I've got an idea. Lets get someone with some lightweight wheels on the track. Get a baseline of performance. Then, we'll add on about 3-4lbs of tape-weights to each wheel and redo the test.

done.

at least then we can throw the "wheel stiffness" etc out the window to an extent.

I traded weight off on the wheels for weight on at the tires with my 17x9 RPF1s on 245/40R17 Dunlop Z2s. I don't think the acceleration or braking changed on the car during AutoX, but the amount of traction sure as hell did. (And the suspension upgrades from @Racecomp Engineering and @Whiteline didn't hurt either).

Just because you have an NSX, doesn't mean you have a clue.

What he said! Sure 20lbs doesn't sound like a whole lot but it really is, especially coming off of your wheels. You WILL notice the difference unless you are completely clueless when it comes to driving and the communication your car is giving you.

I would go as far to say that you would notice a 10lb net savings on your wheels.

I have 17x7 RPF1's with hankook v12's. Saved roughly 6 lbs per corner..car is much lighter on its feet, the v12's are definetly not rs3's or star specs, but a pretty good improvement in grip over stock.

Agree. I noticed a difference dropping just 3.5 per corner or 14 total pounds.

What are your goals? Autocross/track/better looks/more grip? What is your budget?

Compared to stock..then going to a lighter wheel but wider and heavier tire..even a -5lbs wheel (ex: rpf1), I don't think it'll be much a diff anymore... after the tires, you'll be saving maybe only 1-2lbs per wheel compared to stock from going full oem setup to a 9" wheel with 245s. The improvement will obviously be more about running a wider wheel and tire while keeping things weighing fairly similar as before.

I am running 16x7 Volk TE37s and 225/50/16 Hankook RS-3s, yes its smaller and people will complain it looks funny, but they are significantly lighter than the stock setup.

Track, look, grip

Currently I am looking at going with enkei performance klamps at 18x7.5 running a Goodyear ls2 sport tire at 225/45/18

I have a 10 series fr-s so they will def stand out on it weight is at 20.8Lbs and stock are at 22.8 so I am cutting 2Lbs off per corner with them

Those wheels are sharp. I love me some double spoke design!

But not so fast on the weight savings...remember your bigger tire will weigh more...not sure the exact weight on your Goodyears, but I'm guessing 24-25 lbs each compared to the stock Michelins (20lbs each) and you're actually still adding weight per corner.

I keep going in circles with this very issue! Now thinking of just staying with stock size with lighter wheel and higher performance tire in a 215/45/17.

The tires I'm getting are still 20Lbs luckily so I can save it, but the other tires I was looking at the Bridgestone potenza re760s are like 24Lbs
