yeah thats what i want to run also i was using some this last weekend for like one pass i didn't see any real gains but the tires were pretty much shot and it was getting late and the track was totally unpreped at that point
Nope I didn't have a problem with them but then again I don't have tail pipes so sorry I can't help you there. I have heard of people running a 6.5 bs with tail pipes though.
