looking for pointers on 3 link setup with either a spring bar type pull bar or biscuit type pulbar. car is a camaro clip offset csc sidewinder and we are allowed to run oem ctrl arms for lowers and uppers if we run them i have 2- 24-1/2 inch arms and 2 19-1/2 arms my question is should i run a upper and a lower arm on left rear to stabilize rearend and just a lower on right side with the pull bar on top. we are not allowed to float brackets and are allowed only 2 adjustment holes on each and of arms not sure on pullbar. my idea with the one lower on rr is for rear steer on throttle to tighten car but may be bad idea with the pullbar. im in unfamiliar waters and any help would be greatly appreciated

cd2, I'd be interested in your opinion as well. My car has the same rules, but no pull bar allowed and I'm thinking of trying different things this year.

YOU ONLY WANT TO RUN THE LOWERS WITH THE PULL BAR BEING EITHER THE SPRING LOADED OR RUBBER BISCUIT. IF YOU RUN A STOCK UPPER, IT BASICALLY DEFEATS THE PURPOSE OF HAVING THE PULLBAR ON TOP OF THE REAR. THE UPPER WILL NOT ALLOW THE PULL BAR TO WORK AND WITH THE PULL BAR AND A STOCK UPPER IN PLACE, YOU'LL PROBABLY GET A MASSIVE AMOUNT OF WHEEL HOP ON CORNER ENTRY. DO YOU HAVE A RULE AGAINST A PANHARD BAR? IF A PANHARD BAR IS ALLOWED, YOU'LL BE BETTER OFF JUST RUNNING THE STOCK LOWERS, PANHARD BAR AND THE PULL BAR.

Manic Motors has a question similar to mine.If these lower control arms are still running forward to the frame at an angle will this cause problems with the suspention?Were using a metric frame and stock link hook ups for the rear end. Id like to eleminate the top arms and use a pull bar plus a straight pand hard bar behind the rear end.

NO IT WONT CAUSE A PROBLEM UNLESS IT'S AT AN EXTREME AMOUNT OF UPWARD ANGLE. HOW MUCH ANGLE IS IN THEM? YOU CAN GO AS MUCH AS 5 DEGREE WITHOUT HURTING TOO MUCH. THE MORE ANGLE THE MORE IT PROMOTES FORWARD BITE BUT AT THE SAME TIME, EXTREME ANGLES CAN CAUSE SEVERE WHEEL SPIN OFF THE CORNER AND EVEN IN THE MIDDLE OF THE STRAIGHTS. I WOULD USE THE STOCK LOWERS, A PULL BAR AND A STRAIGHT PANHARD BAR. WITH A MULTIPLE MOUNT ON THE DRIVERS SIDE. THIS WILL ALLOW YOU TO TIGHTEN OR LOOSEN THE CAR WITHOUT CHANGING TO MUCH OTHER STUFF.

ONE OTHER PIECE OF ADVISE. THE STOCK LOWER CONTROL ARMS HAVE RUBBER PRESS IN BUSHINGS IN THE THAT WONT ALLOW FOR ENOUGH MOVEMENT UP OR DOWN AND IN ESSENCE WILL CAUSE SUSPENSION BIND. KNOCK OUT JUST THE METAL SHIM IN THE RUBBER BUSHING AND REPLACE IT WITH THE SAME SIZE WHITE PVC PIPE AND LUBRICATE IT WITH GREASE. THIS WILL ALLOW FOR A FULL RANGE OF MOVEMENT WITHOUT BINDING UP.
