I wanted 20's from the start until the track day I attended last week at willow springs.
the only person who had any issues with their tires was the guy who had 20's on his car. The very small sidewall (that i thought would help in the corners) actually hurt his driveability on the track! He broke the rubber loose from the rim in the first run and then later in the day it broke loose again AND he bent the rim!
i will not get 20's now just because of that....

agree... the unsprung weight on 19s, let alone 20s, will affect your performance...
plus the extra rubber you get from running 18s and 19s will help protect your rim investment... not a bad idea considering volks (for e.g.) run 2200-2500 for just rims
I'm going with 18s for that reason (and price)... but IMO you'll be happy with 19s

I've heard this same kinda thing from my shop guy. When we told him we were thinking of going to the track, he made a big point of recommending we bring an extra set of rims and rubber (17s or 18s), cuz he KNEW we'd get smoked in the 20s.
It's funny, I used to think looks for the sake of looks was enough, but this discussion on 20s has changed my mind: if the wheels hinder performance on the track, I don't even think they should ever get strapped to my car. My wheels should look good AND be functional (ie: 19s or less).
Thanks for the physics lesson D350z
You've made up my mind: 19s it is!

But sometimes it's not just the weight of the wheel that makes it heavy. Tires are actually pretty heavy too. For example, the wheels I have now weigh in around 26lbs for a 20x11. I weighed the 17 and it was around the same weight. So I think I am ok as far as performance is concerned. I definitely did not feel any differance in acceleration afterwards. I noticed better cornering grip.

just keep in mind that 19's will left a untolerated gap from the fender. my wheels are going for $3500. i'm selling because i'm working on something new with iforged. the set up that i'm going with is something that they really don't do but, they will try it.
and yes those are the same wheels

The rim that is 20" will require more effort to turn then the rim that's 17". This is because more of the rim weight on the 20" is further out from the center, thus harder to turn. Bottom line is you will lose HP with 20's compared to 17's of the same weight. Performance at the expence of looks and looks at the expense of performance, your choice.

The larger your rim, the slower the car. Every inch makes a difference, but how much of a difference. 17 to 20 is a big difference, and 19 to 20 is a small difference. How does your car look when it is standing still? Like this....20" rims with 1" lowered suspension..

the "ONLY" 1" comment is a little scewed, since most 20" wheels are of a heavier variation (Chrome plated, or made out of cheaper materials, etc...) In other words, there are not many 20" wheels that are made for the track or to be light wt. Another thing, the wheels are only 1/2 of the equation, 20" tires are much heavier too.
But, I agree, buy what you like

Whoa... what kinda cheap 20s did you have? Forged rims won't flex. I haven't had any problems with my rims and I have like 1 or 2mm space between my big brake kit.
15's won't fit on my car. Only some 18's clear my front brakes too.

I had 1mm of space when I had the lowenharts and almost 2mm
when I had the armanos. But anyways they were too heavy since they were chrome.
