Sandor-Try a Protoform Vauxall.
I have not yet decided on sway bars at SoCal Raceway. So far no. I haven't even been dialed in yet for set-up. But getting close. The cool temps are what is hurting me. Also competing against pros, really pushing my driving ability.
Included hop-ups should also include the grey front belt.
I know someone posted a couple days ago about the front one-way has too much side to side movement. I now have the one way diff and it to has side movement. I personally like the side movement because that means the diff is not clamped down or binding. I know my rear diff has no side movement which tonight I will give it some.
