Not 100% legal by the NHRA rulebook but the chassis shop that does them has never had an issue and none of the 5 tracks that have teched it have said anything. It makes it a little easier to get in and out of too!
The only thing they have pointed out is it needs some type of head support since it's a low back bucket seat. Going to whip something up this winter.
I'm running two different tread patterns. I have Nitto drag radial in the rear and a summer radial up front.
