Thanks Carl.

1. So I suppose the new upp rear arms will come with fittings to move the upper hinge pins in?
2. Less camber change = maximum tire contact patch(assuming correct camber of course) = more grip and good for low bite tracks. Is this what you mean?

Very strong yes. Interestingly, it's also underweight - good and bad.

Hey guys the last time I ran my MRX4, the engine revved nice n high off the ground, but on the ground it ran quite a bit slow. Could this be that the adjuster nut is too tight? I had this problem with the R40 and the only way I got better acceleration was to loosen it. Aside from that maybe leaning out the low end would help a bit? At Floyd the car revved very weird like bbbwwwWAAAHHHBeewWWAAHHHbeeeWWAAHHH. I guess I need to take some time to really see whats up with it. Also, the plugs are a tiny bit smaller than the RB turbo plugs so maybe Nova's only will fit and run best with it. Soon as it gets going I can't wait to take it to the track.

The lever you are refering to is used to achieve equal droop on both sides of the car without the swaybar hooked up, once you get them even then you can use the sway bar stops to adjust droop.

so-

1- do i start with the droop screws fully backed out?

2- does the sway bar have to be fully removed from the car or just fully extended to set the cam position? at full extension my sway bar is still engaged (although just barely).

thanks!

Default New Rear Upper Arm Set

Can anyone answer what will be accomplished by using the new upper arm set. I know that it will give more rear traction. It comes with two different set points can anyone give me more insight on how this new rear end works....Thanks....

No problem.

Over here, I'm waiting for the upgrade to arrive. Let us know how your testing outcome is with this part. What do you mean by problems on your track?

Basically rear traction problems. We had too much front steering and not enough rear traction....The problem has been solved by placing Sand inside the sealer to create better traction.
