As some of you know, I ran Motive 3.90 gears in my car for the last year or so. While I was pleased with the middle ground it gave me between 4.10's and 3.73's, I can honestly say I will never touch another Motive product again. I picked the car up from my local shop, Delk Performance today after installing FMS 4.10's. No more noise. None. I had thought the problem may have been amplified by the aluminum diff bushings, coilovers, ect, but it wasn't. It was only the gear. Run away from Motive, unless your helmet has earplugs installed. Seriously, they're that loud.
I can't wait to try the KB IRS out next weekend at Nashville Superspeedway.
