I will be running drag radials (Nitto 555r), no slicks. Mostly highway pulls, not from a dig or shifting super aggressive. I am looking towards a Ram PowerGrip HD and nodular iron flywheel, with new shift fork. For the moment, I will have to stick with my t-45.
I'll be looking for some good axles and a driveshaft to upgrade, so I am open to suggestions. Thanks for the help
The driveshaft isn't necessary to upgrade, but you can always do a aluminum to free up Rotational mass, thats always your #1 goal
as far as axles you can always do a 31 spline upgrade. i know it "sounds" stupid going from 28 splines up to 31 but theres a world of difference.
many companies manufacture them, heres a few key elements to the rear end stuff.
1. Your rear end is 100% compliant with a 99/04 mustang gt too for those that don't know the axles are a inch longer. so if you're ever looking to space your rear wheels/tires swapping this rear into your car will make that process safe. instead of rolling dice with wheel spacers.
2. The 2003 cobra differential is 31 splines, so you may have a better chance to pick up one of these in a parts shop/ebay/craigslist blah blah easier then going out and grabbing a 31 spline differential from a aftermarket supplier.
also consider upgrading the clutch packs while you're doing the differential, the 03 cobra also uses a better clutch design for the differential. All of these little things add up in the long run.
Pull the rear, build it, do it once, do it right.
