well i have a 6 speed camaro with a 9 inch rear, ajustable qa1, adj. torque arm, bmr lca's and relocations bracket it has stock springs with water hose mod and im on 275/50/15 mt drag radials and my car wheel hops very bad i have my pinion angle at about -2.5 degrees and i had my lca in bottom hole and shocks on around 4 clicks and it wheel hopped really bad every time i tried to launch so the next weekend i tried middle hole on lca and it still hopped bad and i was only launching at about 3500 so i tightened shock to about 7 clicks just to see if shock were to loose and it started hookin but boggin so i tried launchin harder and as soon as i launched hard enough to break traction it wheel hopped again everytime i break traction it hops very bad and i dont know what else i could try or possible problems that could cause it any information will be appreciated...

I have found wheelhop can be caused by incorrect angle of your LCA's. How do they look, from the rear axle are they angled up, down, or level. You will want a slight upward angle, if they go down or are level that's probably going to be the cause of your problem. Is your car lowered by any chance, ride height will affect LCA angle.

Well the first weekend it wasn't lowered and I had lca's in bottom slot and it hopped bad then next weekend I pulled the rubber off top the spring and done the water hose mod to lower it some then I put lca's in middle hole and went back and it still hopped bad I played with shock some and it got little better cause it was hookin but it was boggin so I launched harder and it started right back hopping

Are you on your lowest hole with the Relocation brackets? I had wheel hop when in the top hole, i lowered it down with my adjustable LCA's to the bottom hole in the relocation brackets and its fixed.

Whats your air pressure? Like others have stated usually lowering the rear of the control arm to a lower hole stops the wheel hop.

I have a lowered car and put LCA relocation brackets on to help with wheel hop, didn't help, played with the shocks(QA-1's), put BMR LCA's in, finally installed an adjustable Chassis mount torque arm and have never had an issue since..

I know of a local car that had bad wheel hop no matter what was adjusted.
turned out to be they used the stock 12mm bolts instead of 1/2 bolts in the aftermarket arms

I've tried lca's in all holes still hops...


I run 15 psi in tires and have adjustable torque arm...



I still have stock bolts in My lca's could that be the problem that I need 1/2 inch bolts...

Is it a chassis mount or tranny mount torque arm? Like I said I changed from tranny to chassis and solved my wheel hop issues..

Tire pressure too low? Have you tried any other pressures?

Its a Tranny mount style a random technology but I have a bracket weld to cross member to hook it in


Ice tried 16 and 18 psi still hops...

Try setting the shocks at mid setting, set the tires at 20, to stiffen up the sidewall a bit.[Sounds like you are "running over" the tires, due to insufficient sidewall support.] A video of them would add more info.
Also, check the t/a clearance at/near the seat belt anchor plate. Some 9"/lowered cars can have interference at that point, and totally screw up the chassis setup. Also, check the brkt and the bolts @ the 3rd member.
Did you use the poly bushing that came w/ the t/a?
Last: Do you have an adjustable panhard bar? Was the rearend centered, after you lowered it? That will affect t/a clearance.

I don't have adjustable panhard but car was hopping before I loowered it...
3rd member is good and I got poly bushings
I run car last night on street just to see how it done with shocks adjusted middle ways and bout 18 to 20 psi of air still hops
