Not sure if anyone else has ever done this mod?....i got the idea off the GTIROC, so is suitable for the B13, B14, N14, N15 chassis.
Can you see what i`ve done?.... All you need is camber adjustable topmounts which you rotate around so the adjuster now sits at 45* giving you adjustable camber AND castor. All you need do is drill a new hole, as the other 2 line up.
Not had an alignment check done yet but it looks like it gives a couple of degrees of castor and camber. Maybe one for the track guys?
First impressions: quicker turn in, increased oversteer and ligher steering ( a bonus if you have NO PAS like me! )
