wats the fattest low profile tire that can fit into a stock 89 firebird, with roh RTs. cause im looking to buy some, im not sure with 17 or 18, so list both plz, and im also gonna lower it, i wish 3 inches but i guess ill live with sportlines.

 

The RT's are available as 17x9's, 18x9's, and 18x10's. With the 18x10's, you may barely be able to stretch 315's on there, but 295's would most likely handle better on that width of a rim.

A 3" drop will put the front of your firebird close to the bumpstops, and would almost eliminate any front suspension movement you have. Are you going more for the style, or for the handling? You can always pick up a set of Moog 5664 springs, which are quite a bit stiffer than the Sportlines if you plan on autox/open tracking the car, and cut the coil as needed to get the right height. The best option would be a weight jacker kit from Ground Control, with competition springs. This lets you dial in the ride height exactly for what you want - if you're lowering it for shows, you can keep it at a more normal height for everyday driving. Just a thought...

 

well im kinda going for a both style and handling, this is my daily driver, and i dont think im going 2 do any scca racing or wat ever with it, so i think im going 2 go with style. But i also want the car to be able to put it down nicely at the track, like i said I really want a street strip car, cause i already have my 1967 camaro with 502bb drag car

 

that weight jacker sounds interesting, how much does that run, and another question does any one sell lowered spindels, i dont think so. but im askin away
