Cosworth powered Subaru STi is getting ready to take on Superlap!

This WRX STI hatch has undergone somewhat of a makeover since coming through the doors. This client of Tunehouse originally wanted a road car he could get out and have a bit of fun at the track on his days off. With the red mist of motorsport however comes a certain hankering for more… over everything!

Wind the clock back 12 months and you may recall a quick update on our website about particular car being upgraded with a Cosworth 2.6-litre crate engine and few tidy ‘bolt-ons’. Now you will see the ‘bolt-ons’ have taken a ‘custom’ turn for the better with E85 now truly the breakfast of champions and some stump pulling AWD fun being the result.

We can’t release the output just yet because to be honest – the client doesn’t know just yet, but he will… very soon. The car has gone on a major diet with as much weight as is feasible given its category of racing at Superlap this year we’ve mated that to an equally impressive improvement in grunt.

We’ve got some Clubsprint friendly aero changes due for delivery and the big MAX SPORT Cosworth Racing brake kit also on its way from our friends on the USA. New race seats keep the driver and co-driver in one place when trying to tame the STI and the suede Momo race wheel makes turning corner much more fun!

Stay tuned as this client is really looking forward to some test days and of course Superlap itself to really shake of the dust and let the STI truly show its stripes.
