Any update?

Sorry for the late response – way too much going on.

I did indeed run the arms at TWS for 8x25 minute sessions and they were fantastic. Everything I was hoping for. The final setup for the proto II’s were
DF PF
Camber -3.0 -3.0
Caster 4.3 4.3
Toe 0.01 0.00

I had the rear camber set at -2.3 for both tires.

Note: That is all the proto II’s could give me in camber and caster hence one more version (the final one I am sure after all the testing we did) will be coming out.

Compared to stock setup, this was an out of this world configuration for me but I would like a touch more camber and more caster up front at the end of the day. The final version should be coming out next month if the machine shop does their job.

It felt very strange after 3 years of actually being able to turn the car more in a corner once I set my hands. Normally, all I could do is point and shoot and then the car would understeer through the corner and then I would try to throttle steer as best as I could to bring the rear around (all you track hounds know this feeling). This setup gave me all the front end grip I have always wanted but I had no snap oversteer tendencies with the rear alignment setup. The rear end was totally planted and I never once felt it trying to come around. I guess I just didn’t push it hard enough although I was running just 1 second off my best lap times. I run Nitto NT01’s with 18” rims – with 275/35’s all the way around. After the event, it was the first time I ever had tire wear on the inside 1/3 of the tire. Pretty amazing what camber will do.

Well the proto II’s are now on their way to the Pirelli World Challenge folks to see how they work for them. I can’t wait for the final product next month.

That’s what I know for this moment. I am running COTA this weekend and I sure wish I had those arms. Oh well, back to point and shoot with throttle steer!!!!!! No worries, I have had lots of practice doing that. lol

Cheers.
