Thanks Grandpa.
Yes I have the alu steering stuff, along with several other alu hop-ups and the carbon fiber front shock mount.
I have tried the s grips but I did not like them. The were inconsistent, car didn't drive as well as with the type A slicks.
I have tried yellow springs front and blues on the rear and the car would bounce in the corners, which is why I went softer.
When I drove with a clean diff I was getting lots of wheel spin when coming out of corners and other cars would pull away on the exit.

I will lower the rear ride height and try the s grips again next week. One change at a time. I am the race director, I can't make changes between rounds. I have to drive it the way I brought it. I can change tires, that is simple and quick.
