Ok so I'm pretty sure I'm just gonna keep the 205/50/15 and get 7.5" rims. Hopefully I will have enough money to get a better tire.

i don't really see the point in upgrading to a 7.5" width...
kind of a waste of my money in my opinion, you're already upgrading so might as well spend a couple more bucks and get some wider wheels, especially if you're upgrading for performance reasons...
but hey, that's just my opinion, i'm kinda bias towards wider wheels anyways
wider wheel=wider tire=better grip :D
Fixed. :DQuote:

My stock wheels are 15x6 and weigh 12 lbs.
Reducing unsprung weight minimizes the load placed on controlling the motion of the wheels and tires. This means that suspension springs and shock absorbers will have a greater reserve capacity to control body motion -- just as they were intended to! The result is better handling, which we are all after.
Very good point!Quote:

That being said I kind of have the perspective that although wider wheels and tires may have a small decrease in your car's acceleration and maybe handling, you can always increase acceleration and handling in various other ways...engine mods, intake, exhaust, coilovers, sway bars, etc...
But what else is gonna give you better grip other than tires... ::Shrug::
Sorry for the confusion Sam, I wasn't referring to your wheels.Quote:

No confusion...my point was 18x10 RPF1's at almost 20 lbs., while much wider, are also much heavier than 15x6's at 12 lbs. You have aQuote:

The debate is great but has anyone systematically tested one tire/wheel combination against another. These cars have been around for over 20 years but the debate goes on.
I have. With 185/60/14 Dumflop Somethings on my stock daises I can't get to the end of the road without getting sideways. With my 16x7.5 SSR Comps with 225/40/16 Toyo T1-S it isn't an issue at all, unless I'm purposely driving like that. How's that for systematic?Quote:

So are you saying that you like the wider tires better or you just like the Toyo's better than than the Dunlop's?Quote:

If I do upgrade my wheels anytime soon, I'd probably be in the market for some 17x9's at 15.9 lbs. 245 would be a good fit on those.Quote:

The Dunlops are some H-rated M&S tire, the Toyos are obviously high performance summer tires - apples to bananas comparison.Quote:

I just put my last set of T1S on the rear of the car, but need fronts soon so I am leaning towards 215/40/16 Kuhmo r-compounds this time. I am a Toyo whore (was Toyo retail certified back in 2002-2004), but willing to stray from the brand for the sake of traction. Compound is way more important than width, so a 215/40 r-compound will out-grip a 225/40 street tire any day of the week.
I'm really leaning towards 17x9 RPF1's for the NC, they weight 15.9 lbs each...
Bear in mind that the tires you choose can often eat-up the weight saved on ultralight wheels. Some tires out there are 2-3 pounds different than other brands in the same size. I'm all for lightweight, but be realistic about what you'll actually get for your $$. I had 9.5lb Volks on my Yaris and a total wheel/tire combo weight of 23.5 lbs, but still couldn't beat the ST and STS Civics, CRX and Miatas. Samm's comment about letting the suspension work is the most important in this thread, even if he is a douche.
That being said, what size wheel do you think works best with the NC?Quote:

I think 245's require fender rolling too, depending on how much the car is lowered.Quote:

If I was forced to live with one setup, I'd stick with 8-inch wheels, I think. Especially in the 16x8, you get a little more sidewall for ride comfort. The tradeoff of weight, rolling resistance and clearance issues just don't justify the aesthetics of 17x9's, IMHO, unless that's your priority. What's your ultimate goal? If you want a good DD that will also autoX well, its hard to argue with the 8" wheel with some StarSpecs. If you want to go full-on track-ready and look badass, then throw the big meat on there and don't look back! (or calculate 0-60 times, MPG's, potholes, etc.) :)
