what do you have leaf or coil car and are you trying to rearsteer the car so that you can drive into the corner better?

Measure your wheel base from the center of the front tire to the center of the rear tire on both sides of the car. Make sure that the driver side measures less than the passenger side. If it doesnt, that could be your problem. My car is set up with 113" on the driver side and 114" on the passenger side. I dont think you want to go more than 1" difference. Start by adjusting 1/4" at a time until it feels right.

I've never heard of anyone doing that so i really dont know what to tell you. But I use an 2" OFF SET wheel on my left rear and my right rear is 3" or 4" and i've never had anything break nor problems. Personally I'd go back to the stock position or however you all had it first and try a 2" offset wheel on your left rear......

I've had a lot of people tell me not to lead the rearend at all. If you do, an inch is a ton. You're breakin stuff because you've led it way too much. I put a 1" shorter lower left trailing arm in a new car and put a stock one back on because I thought 1" was excessive. The housing was visibly **** -eyed.

In my opinion, leading the rearend is a crutch. It may make things better, but you would be better off to get the car to handle with weight, springs and wheel offsets and leave the 4 link straight and happy. Its not a very good racing set-up and complicating it by misaligning it can't help.

in my opinion......bolting the rear housing in the chassis crooked is a crutch too...BUT, with the rules what they are at most tracks I would say this is acceptable practice........

with stock trailing arms and stock mounts this is what you will need to get close...
the lower trailing arm is closer to the you will need to move that mount farther..............

The street stock guys I help that do this I steer the rear 3/8 inch........I shorten the left side lower 3/8 I just slot the hole in the trailing arm near the rear end, then weld a grade 8 flat washer on.......

The upper trailing arm is soooo close to the center of the chassis the amount it will need to be changed is a lot less.......I move it 1/8 inch to 3/16.......same deal, weld on a flat washer.......

If you moved both trailing arms the same amount they will have a bind.......normally the rubber bushing will take up the bind, but the chassis will not handle correctly.

I would assume you are using a solid bushing, the bind it tearing things off the car............

As for tearing shocks need to cut off the lower mount and re-weld it at the proper angle..........again, the shock has a rubber bushing but it is not allowing the shock to move front to rear far enough..

I lead my rearend 3/4 inch and I like it better than straight up. I have never really had any problems out of the ordinary. I wouldn't think leading your rear would have much effect on rolling the tires off the rim.

As Awkwardjeff stated, unless you correct all your linkage points for the new angles for leading the rearend, you're going to stay in constant bind. As Dunbar stated, I also ran my rearend straight up and used offset wheels to make the chassis adjustments, coupled with tire pressure. Rolling tires off the rims? Well, if you're running to low of pressure w/o a beadlock on the RR, you're going to roll that tire off no matter how you set the rear suspension. Leading the rearend is not a bad thing, it's recommended for some 3-link chassis, etc. But, unless you make all the necessary adjustments, you might want to stick with keeping the rearend square and work with the balance of the components (shocks, springs, rims). It's basic, easy, and if you have a problem, you can always get help quick vs. a custom setup. Just my couple pennies.....

We always pull the RR wheel back. That also gives you a better pinion angle.
