I run an STi V3 in hill climb competition on my stock gearbox/clutch. so far no probs with full bore starts etc. If it does go bang, thinking of above mod.
Any viewa/advice/costs etc from those who have done it much appreciated. I drive this car to and from the events so must be driveable on the road!

speak to mark directly. he isnt a salesman as such and won't sell you something you don't want and need.

You may find he disuades you from buying a kit from him.
