**This is take 2 because i had initially posted it in 240gen and someone suggested i post it in here as well. Please don't yell at me mods! **

I'm not quite sure where to post this seeing as it could arguably be put in suspension/wheels, brakes/tires or engine/drivetrain so I'm going to post in here. Anyway, I just got back from the track for the second time and and realized that i was not quite pleased with my cars performance through the turns. Fisrt of all, it's an s13 hatch with toyo t1r's on the rear (245/40/17), stance gr+ coilovers, front and rear strut tower braces, front tension arm brace, stock differential and rear sub-frame brace. I'm running about 2.5 degrees of camber in the rear. The problem i had was when i went into a really tight turn and then began to accelerate through the apex, the inside tire (one with least traction) would start to slip like crazy and the other tire would do nothing. My first thought was the differential. But then i started thinking that it might be a number of things including the drastic shift in the cars weight. I was thinking of experimenting with different spring rates (i am running the 8/6 setup right now), maybe something along the lines of a 12/10. I was also looking at the s15 hlsd. Is this a good diff for grip driving? I saw this http://cgi.ebay.com/ebaymotors...ories for sale on ebay and figured that I could just buy this and drop it into my pumkin (since it was made for an r200) and still have the same final drive as I do now which is what i want. Is there any reason why this would not work? Also, i really want to continue to run these tires until their dead which will probably be a while. I know they're not ideal. Sorry for the ramblingness of this post.

Did you try to run it without the strut tower bars? On my stock suspension 90 240sx, I had a front strut tower bar on and everytime I'd go around a corner it lock like it was on rails and it didn't catch traction as fast as without it.

just like your other thread, get a diff. then worry about the springs and bars, as you stated in the other thread

Yeah, disregard this thread. I didn't think I would get much of a response on the other thread but apparently, I was wrong. Mods, you can delete this if you'd like.
