For one thing you drive a Mugen not a Serpent. Everything I have ever tried that Serpent says has been backwards!!!! All I know is I have had the MTX 3 for 4 years, and when I want less rear traction I run the A block, when I want more traction I put C in. It has been the same for all the guys I have talked to.

I would say put each one in and try it out, that is how I learn what a car does.

Yes a higher rollcenter gives the car less roll, but when you are on a sticky track you want the car to roll a little so the car reacts a bit slower. When the car reacts fast on a high grip track, you end up Throwing the weight instead of transfering the weight slowly and progressively.Try to controll roll with the Swaybars.

Last year I went to the Nats in Ohio, I was traction rolling. I asked Josh C. what to do and he said lighten up on the springs and oil to slow the reaction down. It worked great!
