Advise on suspension setup
I've got a 00 t/a six speed with turbo. Have 275 pros with moser 9" with lca relocation brackets. Founders adj lca, Midwest chassis short adj torque arm,qa1 single adj shocks with 300 springs on front and single adj qa1 with stock springs on rear , subframe connectors and spohn adj aarms. I have shocks set on 5 from the bottom. Lca's are level and the torque arm is in the middle hole. When i dump clutch it's wheel hopping for about 30ft then she's gone. I've messed with shocks and air pressure. I had a spohn sway bar but it was flexing so I just replaced it with a Wolfe anti roll but haven't had a chance to go to track yet. Just wanting to know if I need to change anything before I go back to track .I'm new to stock suspension stuff. Thanks

Test it now that the anti-roll bar is in the car before making any more adjustments. My car would twist and wheel hop really bad before I put the MWC anti-roll on. Now, no more wheel hop and the car launches straight, no more twisting.
I moved the Lca to the lowest hole, and it would hit the tires really hard, carry the front tires 6-12" in the air for 20' then unload the rear suspension and spin the tire. Eric at MWC suggested I tightening up the front shocks a couple clicks, and moving the bar back up 1 hole. Get the LCA a bit more parallel with the ground so, so it didn't hit the tires so hard. Big improvement car stays closer to the ground and doesn't spin anymore.

but like other have said, try your most recent changes first and then decide if you need more.
I can't find it now but there was another thread that had graphics that explained it all real well. basically for the street you want the lower control arms level to slightly uphill from the rearend to the body so the weight of the car is pushing down on the rearend, because if it's the other way you lose traction and have wheel hop because the control arms are "pushing" up on the rear end, this is commonly experienced when you lower a car (if I keep the car much longer I desperately need to get a set of these to complete my setup), but you don't necessarily want to go to extreme with it on the street because it could affect your cornering, but straight line drag races don't need to corner and want the best launch so you go with the steeper angle. it's all a balancing act to find what works best for your exact setup.
Well I dropped lca one hole,installed roll bar, pinion angle is at -2 1/2 degrees, torque arm 2nd from bottom hole, qa1 7 clicks from 0. Still hopped a little bit not as bad. Any advice on what I should do nect

Make the torque arm adjustment first. I'm sure it will help. If it still has some hop drop the lca's down a hole. Basically if you have the lca's on the bottom setting but the torque arm moved up a hole or two it's counter productive.
