Respected Subaru tuner Roger Clark Motorsport has unveiled an unparalleled no-compromise chassis upgrade for competitors looking to achieve the ultimate in handling and performance.
Their new Impreza kit is aimed squarely at the top-end competition market and uses the finest materials and construction to allow tuners to run the car radically low for circuit work, without compromising the geometry of the suspension arms. This is achieved by a drastic re-positioning of all key components, meaning that the new, rose-jointed arms can achieve the factory’s desired downward position at rest, as opposed to the undesirable uplifted situation that results from simply lowering a stock chassis set-up. Using this kit, the car can be lowered by over 3” without deviating from the suspension’s optimum positioning.
Material choice is exemplary. The uprights and brackets in the kit are machined from a solid HE15 billet, before being fitted with the very latest Subaru competition-spec wheel bearings and 22B wide track hubs. The studs used are also toughened and extended versions to allow a wide range of motorsport wheels to be fitted. The compression struts and track control arms are precision fabricated from Cro-Moly and utilise precise rose joints to ensure stiffness and accuracy in their movement.
As well as improving the geometry considerably, the kit also endows the recipient car with an increased track of 30mm per side, improving handling and turn-in further still,
The kit is engineered to suit each bespoke application, so can be ordered for any GC8 or GD8 chassis. Understandably, with every solution being tailor-made, prices are available on application.

RCM Start Gobstopper II… The Sequel!
As rolling shop windows go, Roger Clark Motorsport’s original GC8 Subaru Impreza has been something of a success. The ‘Gobstopper’, as it is affectionately known, has not only taken the Leicestershire-based tuner to multiple Time Attack and Ten Of The Best titles, but it has also starred in a multi-platform advertising campaign for sponsors Autoglym, capturing the hearts and minds of petrol heads around the globe in the process. It’s even available as a paint scheme in the popular ‘Forza Motorsport’ game!
Like all true superstars however, Roger’s sons, Matt and Olly Clark have decided to retire the old girl whilst she’s still at the top of her game. Although they’re not ruling out a few ‘demo’ runs at this year’s events, the 2010 season will be the Gobstoppers last official outing, as its replacement is already under construction.
The latest car is to be based on the MY2010 Impreza STi and promises to exploit many of the numerous tricks learned from the evolution of the first car, combined with several new cutting-edge developments that the team have been secretly trialling throughout the winter.
Matt Clark, the technical force behind RCM’s unrivalled success, had mixed feelings about the young upstart. ‘It’s very hard to retire a car that has been so reliable and so successful,’ he noted. ‘But you can’t move forward by standing still. We’ve really reached a pinnacle with the GC8 chassis, and it’s time to see what we can make the latest car do. We’ve already had a 14 month development programme on a road-going version, so that’s highlighted many of the areas we need to address. I love a new challenge and this will really give us something to sink our teeth into.’
With Time Attack achieving true motorsport credibility with its MSA accreditation this year, press, audiences and competitors look set to rise sharply, making the new car the perfect showcase for the team’s talents. ‘That’s a bonus for sure,’ smiles Matt. ‘But the main reason we go racing is to develop new road car products – particularly on the engine side. If we can’t break a 890 bhp 2.0 litre engine, I think it’s safe to say that our customers won’t!’

Current TOTB and Time Attack Champions Roger Clark Motorsport have released yet another one of their own superb trophy winning tricks into the market place; their parallel fuel rail kit.
On the standard Subaru engine, fuel is delivered is a ‘series’ style circuit, feeding first one bank of cylinders before stretching around the block to deliver to the remaining two. In high performance applications, this somewhat simplistic design can see unequal pressures and delivery on either side of the engine, resulting in dire consequences for the ‘last’ cylinder in the sequence.
The RCM solution is a direct adaptation of the units designed and tested by the team on the hugely successful ‘Gobstopper’ race car. The fuel arrives from a central line, before being precisely split into two parallel feeds which then service each cylinder bank. The result is perfectly equal pressures feeding each injector.
The kit consists of two beautifully extruded rails, four dash 6 stainless steel ends, complete with ‘o’ ring, fitting brackets. In testing, the kit has been happy to keep up with the prodigious thirst of RCM’s own 890 bhp test cars, so whatever flat-four trickery you’re planning under the bonnet, it’s safe to say that this kit can cope.
Priced at £425 + VAT you’d be fuellish not to.. Fits all 2001 on engines, both 2.0 and 2.5 litre.
