why 18'' wheels more popular on track?

I actually learned something in this thread. Thanks guys!

Not feeling the tape, but it seems to be a valid means of NOT losing your wheel weights. It just makes me think that it will look silly, lol.

Yep that's what I use - stove pipe tape, but mine is silver.

If the weights are on the inside you'll never see it. If you're tracking your car it's not for show, it's for go. No one cares about looks. Most tape also comes in colors so it will be kinda hidden. My fronts are plasti dipped so I should be ok since a thick layer of rubber is holding them on, also another option.

Look up the wheel diameter on F1 cars and report back please.

Well that's not fair, they weigh 1000lbs. They can have tiny wheels and rotors.

They run inboard brakes, don't they?

Sh0velMan · 01-27-2014, 08:43 AM

No sir.

Sh0velMan · 01-27-2014, 08:45 AM

Teams run bigger wheels to fit bigger brakes, period. F1 gets away with a 16-17inch wheel it because they have the most potent friction materials available, bar none, plus the most aggressive cooling systems, and their cars are around 1200-1400 pounds fully loaded.

During one of our advanced classroom sessions at the track this weekend, the instructor (who seemed quite experienced) had a detailed discussion with us about all things related to tires and rubber and widths and heights and tradeoffs. I'm still digesting half of what he said, and there's no way I could repeat it all anyways, but suffice it to say I came away from the discussion still thinking that 18x10 square is best for this car in the overall. You could potentially see some very small benefit from going wider (at least in the rear), but only if there's another reason for the tradeoff (e.g. to use up leftover points because you were under expected weight for your class or something) - although I'd rather buy aero than wider wheels, I think, in situations where that's an option.

Good to know. Selling 9.5 and 10.5 now to get 10" square with 285/35 or 295/30 or 295/35 if they make something I can afford.

SPOHN · 01-29-2014, 06:25 AM

I run square size tires but my wheels are a inch apart. Until I come a cross another set of just two 9.5 width or 10.5 RPF1's I can more than live with it for now.

synolimit · 01-29-2014, 06:57 AM

Ill sell you either or spohn.

Check out A.M. Brian's offer. That is what he is trying to do is make them affordable. That's why I am waiting to see what happens with those. Races don't start in CT till end of March anyway so I have some time.
