Before you come down on anyone's post, I'd suggest knowing what you're talking about first.10secgoal said:
I never said don't do it, nor did I suggest sticking with pizza cutter tires. Pizza cutter tires belong in the garbage as far as street cars go. If you like the looks, by all means go for it. What I meant by use it is that you'll never reach the performance that a 315 tire is capable of under normal use. I mean come on, we're dealing with leaf springs and a solid axle here. If you have proof that a 315 will yield more "performance" than, say, a 275 that's KNOWN to fit under a '67 without fuss, tire compounds being equal and no other changes other than the tire size itself, show it. Is the extra (if any) performance of a 315 over a 275 really worth the costs of narrowing the rear end, making new leaf springs, mini-tubs, etc? If there was a way to fit 335s back there with no mods I'd be all over that myself but we all know that's not going to happen.
At least 12sec67 admits that he just likes the look, there's nothing wrong with that. I know about g-machines, pro-touring and all that stuff, thank you. I think wide tires look kick ass, but it's not too cost-practical in our cars. In the end it's your car and your money, do what you like.
With no REAL proof that all that hassle is worth it, you guys are just playing the old "swing your thing" contest. Look where Pro-street ended up: who can run the skinniest front tires, the widest rear meats, the narrowest rear-end, the most convoluted roll cage and the biggest, most unstreetable blown race engine while still retaining a license plate. Why? Quite plainly, to outdo each other. Not for performance reasons, but to show what they can spend their money on. At the same time the guys with stock wheelwells, streetable engines and comfortable interiors were walking all over these "pro street" cars on the track and the street. Sound familiar yet?
In the meantime, I'll be doing this to my Mustang soon because, you know, I want to "stand out".
