Lowering springs and shocks ... which ones?

[NOT A TA]

79T/Aman do you need to modify anything to the body or frame to get the 315 in the back ?

I ran 315 35 17's on the back of my 70 bird with no modifications. The early 2nd gen birds have a bit more space and with the right wheel width, backspacing, tire, and suspension they will fit.

My old suspension was Hotchkis, changed everything to a more race oriented set up from PTFB.

thats alot of front tire

it's a 275, on a Firebird we can do a 315 up front.

I have a pair of good used lowering springs MOOG I believe ( 2.5" drop) and a set of rear traction links too if you are interested ?

was stumbling around and found this easy reference page....for moog springs
http://www.74-77camaro.com/susp/suspension.htm

Here is a chart listing a grouping of similar springs, straight from the catalog. These were listed by Inside Diameter; for the 2nd gen F-bodies, mostly 4.080" and 4.090".These are listed for reference ONLY, I do not know for certain if they would work. I do know, however, that the 75-79 Novas used the 2nd gen subframe and they used the CS5276 and CS5278 springs for V-8's, but they used the CS5604 (347 lbs.) for the standard duty 6 cylinder cars, and the CS5642 (420 lbs) for the Heavy Duty 6 cylinder cars. Stock Camaro springs are in bold.
