thanks for the info guys...I did call best of show and they said about 3k off the top of his head...I'm trying to stay with my 17 fiske rims...so I can fit a 315...don't really have the $$$ for 18's and I like the fact I have some side wall...I have a welded up 10" rear...so not sure if it would be better to go with a 12" now...not sure how much more $$$ this will run...
