HOW TO PREPARE YOUR CAR FOR A TRACK DAY

Race circuits are the perfect place to push your driving skills to the max, but you must ensure your car is ready for the stress. Following this simple guide on how to prepare your car for a track day before you go will enhance your enjoyment and take a lot of the fear out of it. It should also help you bring your pride and joy home in one piece!

Prepare your car for a track day

Assuming your car is in good general condition (a recent service is advantageous), here are the most important things to check.

Prepare your car for a track day

Fluids

Ensure that your oil and coolant are up to their maximum marks – take extra with you so you can top up during the day if required. High cornering speeds on track make the oil in your sump move around much more than on the road and can force it away from your oil pump pick-up, which can lead to oil starvation and engine failure – which is why most race cars have baffled sumps – however, this situation is also much more likely if you have low oil levels, so make sure your properly lubed up. Also, your coolant will be working overtime to keep a caned engine cool, so keep an eye on it throughout the day if you want to avoid a cooked engine and blown headgasket. Coolant additives such as Water Wetter or waterless coolants such as Evans Powercool 180 can help keep temps down too.

Brakes

Your brakes will be put under much greater pressure on a trackday, as you brake hard and regularly from high speeds, increasing brake temperatures and wear. A larger multi-piston set up is ideal, but with careful monitoring of their condition, normal road brakes should be fine. Ideally, it’s best to have at least three-quarters of your pad material remaining before any trackday. Running with destroyed pads will dramatically reduce your stopping capacity and quickly kill your discs. It could be worth looking at uprated pads before the day, but remember to bed them in before doing any heavy braking on track. Brake fluid is also important, as higher temperatures increase the risk of boiling the fluid. A good tip is to make sure the brake fluid you have is reasonably fresh. You can check out our guide on high performance brakes here.

Wheels and Tyres

Having a dedicated set of lightweight trackday wheels and sticky tyres – such as slicks or semi-slicks – is a nicety, but not a necessity. Normal road wheels and tyres will be fine in most cases, but just make sure the rubber has plenty of tread (you’ll have to drive home afterwards, remember) and that pressures are at the recommended levels. It’s also worth giving your wheel nuts a good torquing too, as you don’t want to be departing with your rims down the main straight!

Bodywork

Check that there is no loose bodywork and ideally that the headlights are taped-up. This way, if the worst happens and you lose a light, broken plastic or glass won’t be scattered over the circuit to cause punctures for following vehicles. Some people will remove one of the headlights completely, which helps gain additional airflow to the air filter behind. Splitters, spoilers and skirts can aid track driving, but won’t generate any usable downforce, merely modify the car’s pitch and reduce lift. Swapping heavy steel body panels for lightweight carbon items will improve your car’s performance – due to a higher power-to-weight ratio – but make sure you retain the front-to-rear weight balance. Our guide to car aerodynamics offers more advice on improving your car’s performance, you can read it here.

Interior

Inside, remove anything loose in the door pockets and footwells that could become a missile under heavy braking or acceleration, or worse, get jammed under a pedal.

For the more serious trackday fiend, a bucket seat with harnesses is a good move, as is removing extra weight like the rear seats, passenger seat and excess plastic trim. Rollcages are a good option if you are a trackday regular and are concerned about safety in the event of a crash, but are generally not compulsory unless you are competing in a regulated series. Video cameras need to be securely mounted without causing an obstruction and most trackday organisers will want you to sign a disclaimer that states the footage is for private use only.

What track day should I pick?

With loads of events each month all over the country (Covid permitting) finding a trackday to suit won’t be an issue, but here are a few things to consider before booking:

Noise limits: This is set by the local council and will be strictly enforced. If you’ve got a loud aftermarket exhaust, get the dB levels checked. If your car is too loud, you won’t be allowed on track.

Format: You have two main choices: ‘session’ or ‘open pitlane’. The former groups drivers of similar ability into 20-30 minute sessions – this is probably the best bet for newbies. Open pitlane days offer as little or as much track time as you want (as long as the maximum number of cars on track isn’t exceeded), but usually cost more, as numbers have to be restricted by the organiser.

Instruction: Check if there is an ARDS (Association of Race driving Schools) instructor on hand. You’ll find a 20-minute session (about £50), with your own personal Stig, will teach you loads and boost your confidence.

Prepare your car for a track day

What to expect on a track day

At the track you’ll get a short briefing that covers the format and rules for the day and the flag signals. The main rules cover how and when you can overtake and that you must NOT race! Track marshals positioned around the circuit monitor this closely and anyone breaking this important rule will be immediately pulled in to explain themselves. On your first few laps, you probably won’t be familiar with the track and your tyres will be cold. Do not be tempted to go for it straight away as this is probably the time you are mostly likely to have an off! Start slow and build up speed as your confidence grows and tyres warm up. Throwing the car around might be fun, but if you overdo it, you may unsettle the car and risk going off (plus it will take its toll on the car with parts wearing out faster!). Concentrate on driving smoothly – smooth is fast. Aim for getting braking points and corner apexes right. Get your gear changes and braking done in a straight line before turning into a corner then feed the power in gently as you exit the corner and don’t forget to wind the steering lock off as you exit. Practice keeping steering inputs to a minimum.

After a session, always complete a cool-down lap to get some air to the brakes, engine and the transmission, and once stopped in the pits DON’T apply the handbrake, as the pads can fuse themselves to the discs if you’ve been using them hard. Popping the bonnet will help cool the engine too, which gives you a chance to double-check your fluid levels. Also, check the tyres again for excessive wear and that the pressures are still OK; and that all the wheelnuts are tight.

2024 BMW 5-Series spy shots: Popular sedan slims down for next generation

A prototype for BMW’s next-generation 5-Series has been spotted for the first time.

The new mid-size sedan is still at an early stage of development but a number of details can already be identified.

The proportions are reminiscent of the much-loved E39 generation, while the headlights look to be getting even slimmer than on the current generation. We can also see that the headlights taper back along the fender, much more than in recent generations.

When it comes to what’s under the hood, BMW is keen to give customers their powertrain of choice, at least until it makes the eventual switch to a full-electric lineup. As a result, powertrains will include mild-hybrid, plug-in hybrid and battery-electric options.

This flexibility is made possible by the latest version of BMW Group’s CLAR modular platform which supports conventional powertrains in addition to hybrid and battery-electric options. There are reports that even the future M5 variant will offer the choice of plug-in hybrid or battery-electric power, which would be the first time there’s more than one powertrain choice for the super sedan.

Look for the redesigned 5-Series to debut in 2023 as a 2024 model. The M5 variant should arrive about six months to a year later. But before they arrive, BMW fans can look forward to new generations of the X1 and 7-Series, as well as a new X8 flagship crossover.

CONCOURS FORD SIERRA RS500 COSWORTH: BLACK MIRROR

With 450bhp on tap, this Concours Ford Sierra RS500 Cosworth is a very dark (and shiny!) horse that’s taken home a title.

Few Fords look more menacing in your rear-view mirror than a black Ford Sierra RS500 Cosworth. In the 1980s, whether you drove a Porsche 911 on the street or a BMW touring car on the track, Ford’s ultimate Sierra left a terrifying impression on anyone it pushed out of the way.

Kev Murby’s experience of the whale-tailed icon was slightly less visceral, but no less memorable. “I had a very unique picture on my wall at work; it was of a black Ford Sierra RS500 Cosworth parked in front of a futuristic-looking glass building. Every single day I looked at that picture, and promised myself that I’d own one,” he remembers.

Fast forward a few decades and Kev has fulfilled that promise while at the same time bringing this particular example back to its former glory. As he explains, “I came into some money around 2014, and wanted to finally scratch my RS500 itch, but prices were on the increase already and there was no way I could justify spending £100,000 on what is still a Ford Sierra.”

Concours Ford Sierra RS500 Cosworth

Kev was determined to buy a solid car but not a minter, at a sensible price. Oh, and it had to be black. He says, “Over the years, I’ve owned a black Mk3 Cortina, a black XR4i, a black JPS Capri, and I’ve got a black rear-wheel-drive Sapphire Cosworth at home, as well as the RS500. Black cars just look better than any other colour – when they’re clean,
of course.”

Most of us would have failed in finding such a unicorn, but after years of competing in concours events with his Saph, Kev was well connected on the RS scene. He received a friendly tip-off about a Sierra RS500 from well-known Cosworth aficionado Paul Linfoot.

Kev explains, “I think Paul wanted to keep it for himself, but he was in the process of buying a very special RS500 at the time, so sold this one to me to free up some cash.”

Although the car was tired and had been badly painted, it was very straight and honest, and all the important numbers matched – including the engine block and head. At £30,000 it was also good value, so without having even viewed the car, Kev organised for it to be picked up and delivered to his home, where the rebirth of an icon could begin.

Kev didn’t hang about: within a week the engine was out of the bay to be assessed by Dave Pritchard of DP Motorsport, and the car was up on axle stands, where a long and arduous love-hate relationship began between the garage floor and Kev’s back.

He groans, “I spent around three hours every night for months on end, laid down, looking up at the floorpan, cleaning the underside with my little Dremel. It was horrific work and I wouldn’t do it again for all the tea in China, but once the red oxide and paint was on, the result was worth it.”

By now, Dave Pritchard had dismantled the engine and discovered some good and some bad news. The good news was some trick head work had been done back in the day, by Dave Brodie of BBR. Kev says, “It was superb work, but unfortunately the rest of the engine needed a rebuild, as internally it looked like it had been sandblasted.”

The discovery offered Kev the impetus to rebuild it to better-than-new condition. “DP asked what I wanted from the rebuild, and I said to be driveable and quick. We ended up making 447bhp and 396lb.ft, and although you need to stay above 4000rpm to really keep it on song, it is very quick indeed.”

The concours Ford Sierra RS500 Cosworth runs four big Siemens injectors, and the T4 turbo has been rebuilt with billet wheels because the originals are hard to get hold of nowadays. The whole ensemble is kept in tune with a retrofitted Level 8 ECU, live-mapped by PJ Motorsport to a maximum 28psi of boost. Kev doesn’t see a need to go any further, and he sums up the experience of a 400bhp-plus T4-equipped rear-wheel-drive Cosworth road car perfectly: “Hit the right revs, and all hell breaks loose.”

The engine went back into an already-mint bay, as Paul Linfoot had previously conducted one of his underbonnet restorations. The rest of the bodywork desperately needed attention, but an initial respray ended in tears.

Kev explains, “I’d wanted Wayne Parrott to do it, but he was busy with work. So I took it somewhere else, and a year later, the whole car micro-blistered.” In fact, when Wayne assessed the damage, he was able to peel the paint off in strips with a razor blade.

Kev was wounded, but after a second respray, by Wayne this time, the car is still in stunning condition five years later. So much so that Kev has enjoyed entering it into concours competitions alongside his Saph.

He says, “My son and I drive the cars to the events, show the cars and then have some great drives home. They do get used hard, which surprises some people, but life’s too short not to enjoy these cars properly.”

Kev swaps the CXN wheels for a standard set of genuine RS500 items to enter concours, and with such a relatively standard-looking car he has won his fair share of events.

He smiles, “My proudest moment was winning the best-presented standard car at RSOC National Day. It genuinely bought a tear to my eye with pride.

Concours Ford Sierra RS500 Cosworth

“The RS500 ownership experience is much like owning other Cosworths. I get immense pleasure out of driving it, and the cars deserve to be brought to the best condition they can – striving for that goal can also bring their owners so much pleasure.”

So much that Kev has now become the RSOC RS500 registrar. Does that mean he can officially value his own car? “Unfortunately not. But even if I could, it’s not about the monetary value – I’ve finally got the car from that poster, and that’s priceless.”
