Just don't model the cheesy non-functional rollbar "padding". Get the real SFI stuff.

Patrick, why go to 335 on the rear? That's going to be seriously tough to stuff under there. What's the increase in tread width of those versus the 315's?

The 335's are mainly so I don't have to re-setup the rest of my suspension. It's currently pretty much neutral with the 275F, 315R combo, the rear end is too stiff for 315's all around. The 335's should mitigate the oversteer a little, as I can't afford to buy new springs/swaybars now.

Ah, makes sense to me...

It appears the 335/35 Ecstas may not be much wider than the 315/35 Victoracers. No tread width is given for the Ecstas on Tire Rack's site, but the section width comparison is 13.5" on a 12" wheel for the 335 Ecstas, and 12.8" on a 11" wheel for the 315 Victos. The rule of thumb I've heard is the section width of a tire expands by .2" for every .5" wider wheel width it is mounted on. If this is true for this tire, a 335 Ecsta mounted on a 11" wide wheel would have a 13.1" section width. Not much difference. Barring some different information I'd just run the same size tires all the way around and keep the Victoracers.

The 315s are also 25.3" in diameter as opposed to the 26" 335 tires. That's a big difference.

LPEDave, the C5R Camaro in the picture is only my role model for the flares. I think they look really good. I may never need them though.

You're right, that isn't much difference. Looks like I'll have to make some other changes, too, even if I go with the 335's. My budget right now prevents me from spending anything on the suspension right now, so I'll just have to throw the stock rear springs back in and hope for the best. I should wait until I have the funds to do everything, but my codriver will buy the tires if I buy the rims, so it just makes sense to get the wheels now.

Still, the 335's might make enough of a difference to change horrible oversteer into merely miserable oversteer, I think I'll give them a shot, unless there's a reason that I shouldn't. I haven't heard of anyone using this combo before, so it might just be a bad idea.

Can you flip a Victoracer on the rim like the Ecsta, or does the inside and outside refer to more than the (short lived) tread pattern?

The 315s are also 25.3" in diameter as opposed to the 26" 335 tires. That's a big difference.

Actually, that would be an unintended benefit to me. My co-driver swapped in some 4.10's for my 3.73's a couple of weeks ago (for a couple of drag race events), so that will give me back few more MPH in 2nd.

Yeh, you can flip a Victoracer on the rim, no problem.

Just out of curiosity, what did you do to balance your suspension for the 275/315 combo? Maybe there's other things you could adjust to help balance the car with a 315/315 combo?

450 lb/in front springs, 225 rear, stock front swaybar, 1LE rear. It usually doesn't push unless I'm driving stupid, it pushed horribly on the stock springs/swaybars.

I'd go back to a stock rear sway bar before I'd make the drop to stock rear springs, if you still have your stock rear sway bar and bushings. Then, when you get the money to upgrade your front suspension I'd go with a 35mm front bar, and keep your existing front spring rate. Since budget is a factor that would be a pretty cheap solution that should work well. If you can come up with a little more I think I'd go to a 32/21 sway bar combo with 650 lb/in front springs with your existing 225 lb/in rear springs. Just my opinion for a good street driver/track car.
