Garage Hirota’s RWD GC Impreza getting it on…
Cleanliness is Next to Godliness
22 JulAll too often, we’re used to seeing ‘track’ cars tossed together without any real forethought, no real plan. Everyone can appreciate a home built effort, built on a budget, long nights and weekends spent toiling on a cold garage floor. But can you equally appreciate a race car built with top shelf parts, zero expense spared, by a professional shop? This is one of those cars. I can’t recall the last race car I saw who’s build was executed with such attention to detail.
Built by Roger Clarke Motorsport in the UK – this is the Gobstopper. No, it’s not a new build, but so what? Not many cars come along built to this spec, and it’s worth of praise.

Taking it Back
16 DecFor you Stern show fans, you’ll appreciate that this car “….still holds up”. I first saw this car at T.A.S. back many years ago. One of my favorites. The kit is super aggressive, but it still looks fresh today. Posting it up because a customer just asked us to price out some of the components shown, and another local guy just picked up his coilovers for his GC8 coupe project (which is going to be a beast!)
Wide Load
15 JulJust got these pics from a long time client in France. He’s been through alot of project cars, and always does them up fully. This one is no different, but a bit older than usual.
EJ257 engine, JDM 6 speed – he is still contemplating which turbo to go with.
