Will 315's fit?
#1
I would like to go to a 315 in the back. I am now running a 275. I've read on here that it will fit. Can someone confirm this? Also, what size wheel and offset should I use? I remember reading it here a while back but I can't seem to find it..
Thanks...mike

yes they will-no problem at all. I used some 17x10.5's with 6.8 backspacing, which are aftermarket rims for the SN 97 series mustang The backspacing would be better at 6.25 in my opinion, if you can find a rim-or you could use a spacer if your HP level isn't extreme

"I love my Hookers!" and "Get some Strange" probably have a different connotation to non automotive enthusiasts!

Sweet. Thank you. I am planning a 521 stroker build. I'm trying to get as much runner on the road as I can. Thanks..

Your are going to need more tire than that.

I'm now running 325-45-17's (M&H) on the aforementioned rims, this is a taller 28" drag radial

They fit after I cut and expanded the inner wheel well to fit flush against the frame rail If you can cut and weld, this is a fairly simple mod and can be done in a day.

With that much engine, I think you'll need to consider back halving the car.

Back-half? That sounds like a lot of work for a street car. .lol

No need to back halve it.My 521 makes 630+ hp and 645+ tq.It doesn't really matter how big a street tire is you are going to boil them.I run a 295 BFG TA radial on mine for normal driving and they are useless.I also have 295 MT drag radials,they are much better,traction is much more controllable.A 305 or 315 drag radial will do the trick unless you are planning on a bunch more power than me.

Nice to know.. the motor I am planning is a 521, 10:1 comp, Edelbrock Air Gap, P-51 heads, and a 246/252 @ .050 cam. I believe it will be just shy of 600hp.

You should be north of 600 with a combo like that.Mine is a 521 cam is 247/257 @ 50.SCJ-A heads,11 to 1 compression,Torker 2,950 Holley HP.Mine dyno 630hp@5800 and 645 tq at 4400 before a slight cam change,should be up 7-10 on hp and torque now.
