hey joe, dont get me wrong it can be done...but even a low 13 second car, if launching at a decent rpm, will give quite a beating when you dump the clutch...it has been proven time and time again that Bias plies have much better recovery on a stick car than DR's, and thats on cars from 8 seconds all the way to 14...i know a guy who changed from the MT et street radials to an et street with no other changes and went from 13.4 to 12.9...and thats just one guy i know personally, and have seen many others tout the same horn...even if his 60's are high and its only a low 13 second car, id do anything i could thats simple to squeeze every last bit of it, and imo tires a no brainer for that
