I have the stock traction lok diff in my car, I am putting 3.90 gears in it and i was wondering if it was worth upgrading the differential if i already have one? Or would it be worth it to just do the carbon disk rebuild? Does it have those already? The car only has 36,000 miles on it

I heard the carbon disk rebuild is worth it

You already have a Limited slip (all 2005+ GT's do)

BUT IMO a detroit truetrak would be better than the clutch based one.

theclutches will wearout and the detroit truetrak is a better design

I know i already do but i was wondering wht the benefit of an upgrade would be

how many miles on the car? Unless you plan on drag racing a lot or drifting, the stock clutch disks are good for probably 100K+ If you're past 50K a rebuild would be a good idea regardless. I've thougth about the carbon fiber ones for when I do my gear upgrade but I haven't checked into any real benefit.

yeah I think im just gonna do the carbon disks, I might as well i only have 36k on it but like everythings gonna be out already

I did the gt500 rear diff kit and 3.73 gears love it

I'm searching for upgrades too.. My factory clutches gave out at around 40k... I upgraded to the carbon fiber ones... they gave out after another 60k... So, that's probably not too bad..

I don't plan on keeping this car for more than probably a couple more years, or I'd do a Trutrack or something like that.

I need to replace my clutch packs in my diff. I've been thinking about buying the whole rear axle from frpp with 3.73 gears and 31 spline axles. The $1400 price tag doesn't bother me, it's what do I do with my used axle. Try to sell it on craigslist or make a yard ornament out of it.
