I have a lot of hp at the wheels and need a solution to my whel spin. I have 275's in rear, will putting on 295's help that much or do I need lsd?

 

Look at it this way, if you put on an LSD, then the power will be going to twice the contact patch that it does now. There's no way you're going to be able to put on a tire that's twice as wide as you have now to get an equivalent amount traction. Going from 275 to 295 is less than 10% more.

 

+1..put on a 1.5 way LSD or somethin...its 900 bucks..cheaper than tires :P lol or if all you do is drag get a dedicated drag wheel/tire setup for the rear :/ its an idea

 

I doubt it's $900 installed. Probably looking at about $300 labor.

 

..well...yeah...1200 bucks...same as a good set of wide tires..maybe a lil less

 

I take it you have'nt dropped the diff. in one of these? There a biotch.
