My 94 Z was able to pull off low 1.6 60' times consistently with a best of 1.55. I installed relocation brackets a few years back but had noticed that the wheels were no longer centered. I was able to run like that with no problems until recently...

I bought a set of 27" hoosiers ,but because of the offset they rubbed the rear fender. I thought this was the time for me to invest in some adjustable lower control arms so that's what I did.

The wheels are now centered but the car no longer has traction. Is it possible that now my pinion angle may be off? What other things should I be looking for?

Thanks for any help/advice you guys can give.

whats the angle on them: LCA?

The angle of the control arms does matter. I heard many time that they need to be in the lowest hole of the relocation brackets. Well I have found that my car does 10x better with them in the second hole from the top, but I have 4 different holes. Somebody on here told me that you want a very slight angle in your control arms.

Yes, about 2 degrees. If they are angled too much your instant center will be shorter and higher causing the car to unload too quickly.

Bottom hole is not always the best.

Thanks for the replies. I haven't checked the angle because I didn't think the lca could cause the problem. It makes sense though because I had no traction issues before centering the wheels. I was hooking on 26/10.5/16. The new tires are 27"/11.5/15, and I haven't even come close to hooking. The car spins immediately.

What are my options? I don't have an adjustable torque arm. Will that be necessary? My relocation brackets only have 2 holes, with the lcas currently in the lower of the 2.

find out the angle of them and we can tell you if you need more or less to use the other holes for.

Thanks, I'll do that asap.

What I can tell you is that the angle is far steeper than they were before the adjustable lower control arms were installed. Before, the arms were pretty close to being horizontal. Now, the back of the car seems to sit higher than I've seen it in a while.

Draw the rear suspension out as a triangle.
Changing the length on the lca, with the t/a at a fixed angle, won't work..Try it on paper, and you'll see what I mean.

Your LCA's should have the slightest amount of downward angle that you can get from front to back. Use whichever hole gives you the least amount. The length is not important other than to square the rear with the car.

Move them up to the upper hole.

I seem to remember attempting to move the lca up to the top hole but couldn't get it to work. Will it be necessary for me to just remove the relocation brackets alltogether to get the lca angle back to where it would work best? My car isn't lowered so I really don't know if or how the relocation brackets are working for me.
