Heck I'm running slicks and still can't hook up enough to break anything, tire spin is really bothering me. I guess I'll have to move up to some wrinkle walls to get anything done.
Classic 3:31 rear gear in a Jag IRS with a TKO 600. First gear is TO low for me, 2nd is still worthless. Wow, I can't imagine a 3:73. Maybe you should consider a THIRD gear start??
...oop's, there went the clutch, but the ET was fabulous for that run!
