944 Bump Steer & Camber gain

[AZIT]

SCCA Spec944 (Basically built to ITS spec)
'86 944 2.5
Ride-height ~5"

Bump-steer is radical - Does IT allow for rod-ends in lieu of OE tie-rod?

Geometry of lower control arm equally as bad - positive camber gain under compression. Does IT allow for:

1. Fabrication of control arms using OE mounting points
and/or
2. Spacers between ball joint and strut

I've read the GCR - looking for an interpretation or precedent set.

Thx

I assume aftermarket, OEM geometry arms are OK. Like the chrome moly ones etc.?

Why would you assume that? Aftermarket control arms are not legal, nevermind ones of alternate material. If it doesn't say you can, you can't.

why, wishful thinking I guess....

Understood.....confirmed what I thought.

This Spec944 class has really taken-off out here in AZ (21 cars, our own group) - I can run in S944 or ITS with very mild adjustments, or even with NASA as they have a 944 class too (very similar).

Is the value of the 944 being appreciated in other regions?

Appreciate the input on the suspension stuff.

I have the same problem in E Production as its a LP car. wont let us use hime joints or spacers. You can bend them all you want but unless you change the pick up points it wont change spit. You can work on the housing for the struts but you wont get away with it. Learn to drive with the bump,more toe out in the front helps some. Raise the car back up again HA!!
