Well you can 'tear up' anything if you try hard enough!
DV tore up his 9" rear, twisted like a pretzel. Running low gears, slicks and launching at high rpm will do that.
In general the Jag IRS (VERY similiar to what the vintage Cobras ran) is strong enoug to survive serious horse power. I was running over 600 with my side oiler and the IRS held up well.
11.9 at 121 mph with those sticky Goodyear Bill Board tires, still, traction was\is remains a serious problem.
