Default What direction should I take?

So I bought my first camaro about 7 months ago and I love it. It's a 1995 z28 a4 with 153xxx miles on it. I have a decent amount of cash in hand and plan on first going for some c6 z06 18x9.5 all the way around with most likely 275/35/18 in the back and 255/35/18 in the front. After that getting koni shocks and about a inch drop.

But my real question is, What should I do to get around 300-315 to the rear wheels? Using it as a DD and I'd like to e able to do this as cheap as possible but understand this is gonna some cash.

Any input is helpful and really appreciated

Will post pics this weekend of the car when I get the chance.

If you plan on going that wide, get wider wheels now. 315's on 9.5" wide wheels are too much. Especially on low profiles.

Also be aware that 315's are not necessary for drag racing. And for cornering 255's up front and 315's out back usually leads to push under steer.

You will have to do the BFH mod to the inner rear wheel wells and roll the rear lip on the quarter panels to get the tires not to rub.

Don't forget the LCA relocation brackets and the adjustable panhard bar too.

I think by 315 he means hp not wide tires.

Long tube headers, 1.6 or 1.7 full roller NSA rockers, Howard's or Alex's valvesprings ($100) or duals ($200-300) if you plan to add a cam at some point, CAI or ls1 lid, a good flowing catback like magnaflow or hooker, and a mail order tune would get you 300-315 rwhp if you were an m6, it's a little less with the drivetrain loss of an auto being 18% vs a manuals 13%. If you want 300 rwhp in an auto you'll probably need at least a hotcam.

Really appreciate it! Should I be already planning on the opti to fail? I don't know much about it and with over 150k on what I'm assuming isn't a rebuilt engine?

if you don't know the mileage of the existing Opti and if it is not "clean" in appearance from outside, it would be a good idea to replace the cap & rotor with a MSD kit. Opti is just like any other distributor with a cap/rotor, they are wear items

use blue loc-tite on rotor screws when putting new rotor on

This.

I bought my car with 131K miles on it. It had the opti replaced as a "precaution". The current one has 72K miles on it and no issues. Just take care of the car as you would any other and you shouldn't have many problems.
