pics of modified front suspension geometry:
lower bearing as per-VWMotorsport spec in kitcar manuals
basically I have lowered the outer end of the wishbone about an inch to take it back to the right geometry after
lowering the car - wishbone now points downhill from car to wheel (as it should) rather than uphill which throws the camber curve out with roll - now there should be much less gain in positive camber with roll and better use of the tyre.
My slicks fold the outer edge of the tyre over with hard cornering leading to an odd ring of wear around the tyre circumference. This is the sign that the camber is going positive in roll.
This was not easily achieved as the VR6 upright has a
lower balljoint attachment point that is not vertical. Hence the pin goes out towards the disk as it is lowered. This has necessitated changing the offset of the brakes. Also, the
lower balljoint housing was made longer than stock to accomodate this move outboard (so the wishbone is now effectively longer). This whole setup will not work for you unless you have plenty of arch clearance to go slightly outboard.
Have also altered the steering arm attachment point to use a rod end / pin arrangement. This will allow easy adjustment of the steering arm position to change the bumpsteer characteristics.
More info soon as I experiment with setup
Ave it
