ive spent alot of money with them having all the suspension set up, new turbo injectors, lsd, and a few more things to boot. i would highley reccommend them. mark is a really nice guy, in fact they all are. Mark really knows his stuff and after having them set the car up it is now driving so much better than before.
ive had many mods in the past done by different people who i wont mention on here. Having found racingline, ive now got the car how i want it. i feel comfortable leaving decisions up to mark for example he has just redone my engine mounts again as he thought the new ones he had are better and would sound alot nicer. how right he is. it now sounds as good as it goes. you can feel and hear the engine although its not at all offputting, it just adds more excitement to the driving experiance. the engine power delivery is alot smoother now and so much more immediate.
Use Racingline.... you wont be disappointed.
