At my last track day last summer, I mounted my GoPro to the rear passenger door to check and see how much tire spin I was getting under hard throttle out of sharp corners.

I was pretty shocked to see how much tire spin I was actually getting! I would like to correct this issue but would like some feedback on what makes sense exactly in terms of upgrades. I was thinking a TRE rear diff upgrade, but does my transfercase also need an upgrade?

If you don't feel like watching the whole video, you can clearly see at 1:30 - 143 and 3:22 - 3:35 what I'm talking about.

My car is a 2003 with a completely stock drivetrain.

Any suspension mods done?

Having a more aggressive rear diff will increase power-oversteer and will make it worse. What you'd be looking for is an LSD for the front.

 

Only suspension mods are, mr bilsteins w/ robispec springs

 

Front LSD x2

 

you need a front lsd. the open diff is causing it.
taken from wiki

a standard (or "open") differential where one wheel has no contact with the ground at all. In such a case, the non-contacting wheel will receive 100% of the power while the contacting wheel will remain stationary.

 

Makes sense, thanks for the info. Any recommendations on a LSD upgrade?

 

Shep trans t-case upgrade. I went with wave track. Love it.

 

atleast do quaiffe lsd

 

i would get the LSD in the center and the 12 plate kit for the rear.
