I destroyed an entire rearend/driveshaft at Rockingham a month ago. First pass was an 11.2 at 121mph, '04 Cobra. Any ideas how to get H.P. to ground for decent take off/launches? I ahve added 3:73 gears, subframe bushings, IRS Subframe Brackets and had the Kenny Brown hard launch kit and aluminum bushings already and destroyed that too! Has anyone seen the new axle girdle RPM Outlet is going to release? I think a must for all owners. I do not advise using the aluminun no deflection IRS Brace Bushings as I feel was the cause of the major failure.
