Will i have driving issues and eventually move to longer gears? I am contemplating adding a LSD, but don't want do do double labor if I am going to swap out for longer gears later on.

It will drive pretty much the same as it does right now, just with a lot more power when you go heavier in the throttle. If you intend to rebuild the differential anyway, you may as well wait until you drive it with the SC and decide if you want to keep your gears or not.

An LSD is a must for a boosted Z. Even with the LSD, full throttle in first and second gear will smoke the rears and in third gear I get wheel spin above 6Krpm. You will also need to replace the stock rear end bushings with polys. They stock ones will come apart.

I'm running Bridgestone RE-11 305 rears which aren't the best for straight line traction but oh boy, they love the curves!

I currently ma running re-11s 285 in the rear. Planning to go to Michelin ps4s next and up to 305 if I boosted. I wanted to do the LSD along with SC install but don't want to do double labor if I have to switch to longer gears than my 4.08s I have now.

I can't comment on 4.08's in an automatic but I've got 4.08's with my manual and stock lsd. I've also got 305 Nitto NT05's. First gear is almost useless. Second thru fourth are great although it'll roast the tires in second gear and light up them up pretty good in third. It's scary without traction control on (and I very rarely use it) as the stock lsd is garbage and when it lights the tires in second, it's a handful. My next upgrade (very soon) is a Quaife lsd, that should straighten things out (literally). And yes, I'm keeping the 4.08's in.

When both tires are spinning, its not going to matter which LSD you have.

I'm not so sure the stock lsd is locking up properly as it really want's to kick the back end out. I haven't checked tire marks to verify if that's the case though.

In my experience, when the back end wants to fishtail while doing a straight forward power pull, that is the sign that both tires are spinning. Otherwise, if the diff opened and only one tire spins, it wont oversteer because the non-powered tire is still maintaining grip.

I know track guys dont care for the stock vlsd... but as far as power-on straight line traction... I have never had the vlsd open up on me and give me a 1 tire fire.
