Limited Slip Diff.

Limited Slip Diff.
I am considering a new limited slip differential. My car will slip to the side on hard launches. Will a limited slip differential improve power going to both wheels significantly better? And if so, should I go with new rear axles as well. I will be putting a new motor in the car in about 6 months, with forged internals, so I can take the boost up. I am shooting for ~550 to 600 rwhp. This is a street car that may see a road racing course, for a track day, a couple times a year. So corning characteristics are very important to me.
These are the two models I am considering: an OBX Helical LSD or an Eaton Detroit True Trac.

Yes, it is already on the car. However, it is made for everyday use and not going to cause extra NVH issues. Getting something else, like what is mentioned above, will be better able to deliver an excessive amount of power to the ground in racing conditions.

Tru trac FTW. No issues here. As long as you're going FI and increasing power I would recommend that. IF you're going to stay NA then the stock diff is just fine. You should NOT have "one wheel peels" with the stocker. If you do then there's something wrong.
But I am familiar with your sideways slide problem and there are several things you can do to stop that. First of all make sure the tire pressure in each rear tire is exactly the same. I'm sure this sounds obvious but you'd be suprised what 1 psi can do when burning out. Next, I see you've installed a stiffer rear swaybar. This probably helps some. Lastly, and most important, stiffen up the rear D-spec on the side the car slides away from, or loosen the shock on the side the car slides to. Keep fiddling with this and it should correct most of your problem. Good luck.
