Default Lowered an rubbing

Alright guys ive been looking around at some of the drag setups around on here an they look sweet. My 02 camaro convertible has 15x8 weld prostars with the correct backspacing on it. I have like a 28 inch tall tire on it right now. I had to put stock springs back in it an roll the quarter panel in. When i launch it it still rubs, I have kyb drag shocks on it. But I want it to still have the lowered look to it so I want to lower it back down with a 275/15 mt drag radial on it soon. What can i do to get it to stiffen the back some where it wont hit my quarter panels? Is the stock springs to weak? Thanks guys for any help on this as to soon I get my car back from paint im putting my rearmount on with a 3000stall on 8#s! p.s im rubbing the quarter panels not the inner wheel wells.

Hello
This is just another suggestion what a lot of guys do is they see were its rubbing in the wheel well and make clearance for it with a hammer and a piece of wood.
Thanks
Brad

Is it rubbing on one side of the car or both sides? If it's only on one side, your suspension set-up has gotten the rear end out of center. You'll need an adjustable panhard bar, so you can re-center the rear end under the car.

S.O.B As much research as Ive done on here an told friends about it I never thought of the adj. panhard bar myself. Thanks leadfoot4 Another ? could it be off from the factory as im running stock suspension now just with kyb shocks? It mainly rubs my passenger side

The rear suspension under your car (and mine, for that matter) has been under the F-bods since 1982. That's a LONG time, and I've seen a LOT of cars over the years, and for some reason, I always take a look at how they sit. Having said that, I have yet to see very many at the same ride height, so basically, even from the factory, they're all over the place. This, in turn, means that tire clearance will vary from car to car, even when new and/or stock.

I had an '85 Firebird that I lowered, and naturally the axle went off center. However, I didn't have a lot of experience with that set-up at the time (back in '85), so I just drove it that way. Strangely enough, I had one of the first adj. panhard bars that was available back then, made and sold by former GM suspension engineer Herb Adams. However, I seem to recall that the main "virtue" that was mentioned about this bar was it's rigidity and having rod ends instead of rubber bushings. I never thought to adjust it to center the rear end. (maybe the instructions didn't mention this either. I just set it at the length of my OE bar) I have since learned a little more, as well as more companies are now making parts for us to adjust our suspension systems. I have an Edelbrock adj. panhard bar on my '96 Z-28, although the Herb Adams bar is still in the corner of my garage.

Because the panhard bar pivots the rear end in an arc, there will always be lateral movement of the rear, in relation to the body. However, if you're centered up at ride height, it helps in maintaining as much tire clearance as possible.

Have you checked to see if your wheels were made correctly, and both have the exact same backspacing?

Kenny, my race car is lowered and I used to run 325/50 mickey DRs. Trick was to adj the panhard bar so the rear is slightly to the driver side of the car. A half inch will do. That will allow it to clear when launching..

I wanna see the new paint!
