I have a PS box, a manual center link and the Pro-Motorpsorts bumpsteer kit which quickens steering.
The effort is way too high with DOT race rubber. I'm weighing my options for power steering this winter.
5 degrees of caster will rip your arms off by the end of four autocross runs. 2.5 degrees was do-able all day at an open track event.
Bringing this back from the dead.... I was looking at this bumpsteer kit, but I kinda thought this should be adjustable... I'm looking at it primarily to quicken steering a bit, but curious if you still think it's the hot setup after all these years....
I am building my car and I am getting ready to order all the steering bits. Its a 68 with SoT coilovers up front and Zray's competition crossmember. I plan on a fresh PS box from Chock and also the roller idler from Opentracker.
I think Maier is making spindles now with built in quicker steering ratio... not your question really but thought i'd add that info to this thread. pricey sorta, but maybe worthwhile if they fit your overall goals.
