lookin for suggestions

alright guys ive got a 99 camaro ss only mods now are lts, catback, ls6 intake, tune, bmr lowering springs, lca's, relocation brackets, adj phb. im just torn between a 12 bolt or 9 inch. the car is mostly used as a cruiser to car shows and around town but i will take to the track probably only 10 times or less a year. im lookin for suggestions on which rear to go with along with shocks. i just want sumthin that will hold and feel comfortable on the road aolng with being track worthy and the ability to throw slicks on to race then drive it back home. im leaning toward the 9 inch but also not sure if i should go with posi,locker, or the wavetrack ( dont really know much about the wavetrack so some input would be great)

A 12 bolt is ok if you're an a4, but usually a 9" is recommended if you're a m6. If you are an a4, I would suggest a 12 bolt with a posi, and throw a stall and tranny cooler in. If you are a m6, I'd go with a 9", and consider upgrading the clutch and hydraulics too.

I would suggest a 9" then. If you do not have a tunnel/crossmember mounted torque arm, I would highly recommend upgrading to one as well. I haven't heard enough feedback about the wavetrac as to whether they are worth the money or not. I would just stick with a good posi or locker myself, but that's just me.

I concur.

Being a cruiser I'd stick with stock or no more than poly bushings in you LCA's. I went with fully adjustable ones with solids and it is a ROUGH ride. A tunnel mounted torque arm is a great upgrade, as are adjustable LCAs and a PHB. My vote would be for a 9", but I'm a bit biased since that's what I chose.

Good luck with that LS7 clutch on slicks

Let us know how it holds up.

I personally would not get a locker for DD. They get a little tricky on the street around turns.

If you want it geared more towards street use, I would suggest a full-length torque arm and not a tunnel mount. Tunnel mount is geared more towards track use and will be much noisier than a full-length. Either way, get a cross-member for the torque arm to get the front mount off the tail-shaft of the transmission.

9">12 bolt, but the 12 bolt is still a very nice piece. Any which way you look at it, you'll probably be dropping anywhere from $2500-$3000 on a stout rear-end.

Also, I've seen nothing and heard nothing but good reviews on the Wavetrac. I have the Moser 9" Truetrac myself.
