Nice try, not even close ...

So, if you think that you can beat me on the track (245/15 & 295/15 Avons), come on down here - we have some interesting tracks. Who looses pays the track time ---- how about that?

Bigger Wheels = Bigger Brakes

lol, do you even understand the discussion? chassis & suspension yes, car bodies? ... too funny.

I have to say I'm thinking the 15's look best to me personally. Luckily that is what I have, but as others have said maybe some 18's for the roadcourse or drags.

I ran 15" back when they actually made good slicks for 15's (1970's), LMS 16" slicks in the 1980's and 1990's on wider than stock rims (9.5 F and 11 R) and now 18" on (11" F and 12" R) and I can tell you there is no comparison. Yes, part of it is modern compounding but the steering response is so much more precise with low aspect ratio's I would never go back. There is also the problem of tire distortion under high loads
with large aspect ratios especially with poor suspension geometry. There is a reason that the automobile and tire companies gravitated toward larger wheel diameters, they are better.

This guy knows PERFORMANCE, when it comes to Cobras Bruce is a God...

Have you seen this Cobra run, until your car wins the Optima challenge and is not invited back cause he was too fast all my money is on Cobra 3170, I'll pay tract time and bet you thousands if you want, Bruce are you in?

G-Pete 02-13-2014 03:07 PM

I know who Bruce is, I would not challenge an amateur.

I think the wording on the poll is kind of flawed.
It depends on what you are trying to do with your car.

I have 17's on my track car and 15's on my street car.

I think 15's look better but that car will never see the track.

17's perform better and allow bigger brakes too.

The poll is flawed because you can own more than one set of wheels. :confused:

buddyg 02-13-2014 05:23 PM

Well to clarify the question is really for the street. It's obvious the bigger wheels and tires would be better for the track.

So answer the question based soley on street driving.

Beating you would be fun, why don't you come out here, Willow Springs will be running this coming May with the Cobra club, if you are faster I'll pay your entry fee, in fact I'll pay your entry fee to get you out here.
My front tires are 315x30x18 and rears are 335x30x18 and I would estimate that I have 400 HP on you, I am pretty sure you won't be visible in my mirrors after 2 laps.
