try the drag radials first alex and alignment...225 is preferable since its more traction...how bad are you not gettin traction? launch bit lower and play with the gas pedal...when i street race i never floor it out of the hole until 3rd gear haha i know what your planning to use the limit straps for...other racing purposes

 

I've got an EM1 with H&R sports...225's are a little tight. Rub at full lock and ocasionally it'll hit the fender lining on a big bump.
