Default Final suspension adjustment double checking

Okay im taking my car to a well known drag shop tomorrow to have everything double checked and given the final once over. I just wanna see everyones opinion on everything before i take it in so if there is somethingi should have changed i can do it.

TA in top of 4 holes
LCA in second from the bottom
Pinion at -2.3*

I cant for the life of me get this rear end better than a 1/8th" centered which is the main reason why im taking it. The owner is a good family friend so he isnt really charging me anything. He is also welding on my SFCs and intalling/welding my ARB.


The only thing i think might need changing is the TA going in the second hole down. I usually see that as the "normal" setup and i have no idea why i put it in the top one.

Car is a slight weight reduction (maybe 500lbs but more than 400) M6 radial car on MT 295/45/17 (28x11.5x17). Battery in the trunk no a/c blah blah blah on strange DA coilovers 300lb front springs 175lb rears 27 1/4 rear fender ride height and 25 even front fender height

if he has corner scales try to get him to let you put it on there and get it pretty well balanced.

sorry its a MWC complete rear end setup. top 4 of 4 holes, lcas has 4 holes also


camscam i was going to see if he could. I know he has corner scaled a mutual friends car, so im sure he can do it with mine also. He has setup tons of 10 and sub 10 second cars so im just going to drop it off and tell him to make it go straight and fast lol. This is his first time doing a stock suspension style 4th gen and even though im completely sure he will do just fine, i wanna make sure i bring it to him set up close if i can

You need to provide angles of the TQ-arm and LCA, that's important not the hole they are in.

Also how do u go about setting corner weights do u just try and get everything as close to 25 percent on all corners with the driver in the car?

Corner scaling the car is all about making the weight on the rear tires as close as possible. Ideally you want the right side rear tire about 15lbs more then the left rear tire.
This is all done with the car set-up to race with you sitting in it with all your gear on.
