Tubular control arms vs rebushing
I have the most info from when I was running Toyo RA1 225/50r15. That's a good all round wet and dry use, and relatively long lasting r-comp.
Generally this worked pretty well, but it would have prefered a bit a more negative camber.
I can't quantify the rear spring info in a universal way. When autocrossing was a high priority, a higher front spring eye position dropped the rear further.
The past 4 years the car has been set up primarily to handle rough, minimally maintained roads.
Last year, I switched my r-comp tires to Toyo's R888r. But I haven't changed the ride hieght back down yet. Just gave the t-bars a turn down for the road course and about the same for autocross. With the higher ride heights, the camber is around -1. Even with the R888, that looks like its not enough. Not enough time working with them yet. But got one road course event on them, and thats easier to judge from than autocross. Using a slightly larger 235/50 but still on the 7" rims, which is pushing it for most 235/50s but these seem more OK with it than the original BFG Rs I had in that size many years ago.
Amongst other things I'll be trying a step up in T-bars with the new tires. This Sunday I'll just be dropping the front, putting some shock rebound damping back in, and focus on driving better. Its possible to overdrive the front, and that's what I was doing. Its not all in the tire or the suspension. I was rusty and regressing to bad practices last event. It happens easily when not doing events very often.
