Hi all,
New to the site so sorry if this has been discussed I searched and found nothing.

I think I have crossed that line and will only be trailering to the track and running 1320. I currently have rear factory style suspension. It has all been fitted with jegs tubular replacements. I am running Hoosier radials 255/50 16. 458hp motor I want to shoot 250 When the nine bolt blows I will with a 9 inch. Do I stick with the torque arm or do the four link? I have a four link from another project that was aborted. I'm not dead set on a specific racing class I just like to go fast! I should be able to tickle the 9's with the bottle if I can pu it to the ground. Will the torque arm do this? I am having some traction problems now without the bottle but without tuning the rear suspension. It will do 1.6-1.7 60's and a pretty consistent 11.90 but spins off the line and sometimes shakes into second. Staying stock will be eaiser but will it work? Sorry for rambling

I was thinking of doing some springs and shocks also till the nine blot blows to try and get some more traction?

 

there are factory style suspension cars running 8's, maybe 7's.

converting to a 4 link will require back halfing the car, expensive and a lot of fab required.

with some slicks your traction issues will be lessened, and a good set of springs and shocks will help you tune it all, as well as other supporting mods, anti-roll bar ect.

 

^ Some very low 7 second cars running drag radial/stock suspension classes.

I wouldn't back half for 9's.

 

I was thinking of working with the stock layout first too. I may go with some wider slicks though next season when I get a rear end. Hopefully I can get it hooked up so I can get the bottle on it!

 

I would suggest keeping the torque arm! And go with a tunnel mounted. And if you are looking to go with a bigger tire in the rear. I would suggest going with our double adjustable w/rod ends and go with our offset bushings to allow you to fit a bigger rear tire.
