The underdrive rear ring and pinion is best suited to a slick low traction condition, what it does is makes the front diff pull the car around on power with a good amount of stability but does tend to loosen up the rear of the car off power and it does add some drag to the drive train. It's a tuning option and if you can't get the traction and stability in loose slick condition's with other adjustment's that could be an option to try.

The CSI pistons seem to plant the car better than other pistons, the car does jump and land better than with the Mugen pistons, so far i've tried the white 5 hole, the black 6 hole, the Fironi Ergal 6 hole and the CSI and I have to give the edge to the CSI's. A good oil to start with is 50wt front, 45wt front.
