IRS is back in the car with a shitload of upgrades. TBM Brakes, and Kelltrac spec double adjustable shocks. Swapped the diff from a 3.31 to a 3.15 and just picked up the new custom carbon fiber driveshaft from Remkes Garage/Midwest Driveshaft in Union. Freakin awesome work they did there! Heading to Thalmans for a 4 wheel alignment tomorrow and then hit the Dyno for a test session.
