Someone once told me you can take a mixture of camaro and impala control arms and a-frames to improve the camber curve of a metric front suspension but for the life of me I can't remember the recipe. Does anyone know of what I'm talking about? If so can you smack my melon and get my gears unstuck? thanks in advance.

go fast, turn left

ok just spent 3hrs researchin archives back to inception of this forum in hobbystock division. Seems to me that the easiest way to raise the front roll center is to get a set of 78+ impala spindles and or taller bottom balljoints. my next question to bring to the forum is what if any changes need to be made to the tie rods and center link as well as the pitman and idler arms to keep the same geometry as before the change. or do you want to change this also? when using the camaro rotors what calipers do you use? what can be done to take up the approx 1/2" space betweeen the rotor and caliper mount?
as always thanks for your input

BIG BEAR where do you race? your right about the spindles and arms also the extended lower ball joints. i would use the extended uppers too. your rool center will be raised, but you need to check bump steer now. it will be whacked! you can use alum. sleeves with hiem ends on the outer ends to adjust this. you have 2 options here: drill taper out in spindles so you can use a bolt w/spacers or "SPEEDWAY MOTORS" sells and adapter to do this that fits in the stock taper. you can also try diffrent combinations of tie rod ends and ream the hole in the steering arm, but this can be a trial and error deal (you proboably will trash a few spindles) this is info i got from this forum and other racers. hope it helps. neil

Thanks Neil. Just got back from playin POKER with the guys and was kickin around some ideas in my head while I was loosin my *ss. I wonder how a modified large Metric front clip would perform under a small Metric. Just a thought. Am I on the right track or should I have stopped at a six pack?

Know when to fold 'em

i dont know which tierod ends to start with, but if you can get the tierod at the same angle as lower a-arm (on an even plane) its a good starting point. i wouldnt nescesarily say its close, but better than you can get without actualy bumpsteering the car.the car has to be setup at racing ride hieght and tire psi when you do this. i think the inner pivot point on the lower a-arm should be higher than the outer by bout 1/2 to 1" (r/f) the left lower a-arm angle is not as critical. this is based on what other veteran racers told me when i started.
