Lightest square setup for track

Hi all,

I am looking to buy some wheels to square up my 2ss and was wondering if anybody else has any good suggestions on what to get.
I want the lightest setup I can get and I want to run 19's to get the rotational mass down to increse my acceleration times.

Any suggestions?

Forgeline.........if your budget can handle it!?!?!? Contact "Nineball" here on Camaro5, he's a forum sponsor, and he will hook you up with exactly what you want with the perfect sizes and offsets.

Depends on your budget...

Thought I saw you may be prepping for Germany? If you plan to run solo at the stadium, don't go lower than 26" Dia on a lowered car. Carriage will scrape on low grade transitions and street driving too.

Cheapest race setup I'm looking at is TSW 20x10(25-29 lbs each) and nt01 285/35r20. Still will cost little over 3k for everything. Lightweight Forged 19" will cost +4k just for the wheels. Tires will still run 300-400 each. 295/35r19 on 10" or larger tires will need 10.5" to 11" wheels.

What are your goals and budget?

Budget is still in question, but probably high. Goal is to run on the Nurburgring and beat the factory zl1 lap time and be within the z/28 time whenever they run it. I want to be able to keep up with or pass corvettes, ferrari's, 911's or any of the euro stars <300k. I want to keep it completely square and run some ultra high performance street tracks like nt05's.

If you want the lightest then go for mono block designs not 3 piece ones they are more rigid and will last longer coz of durability but they tend to be heavier.

Well, without having to spend a fortune the only wheels I know of that meet your goals are Enkei RPF1-19x10's but I believe they may have been discontinued. There are still some out there if you check around. Retail is about $600 each but you can find them for around $400 if you do some searching. They have an offset of 25 mm so they come right to the edge of the wheel well but I haven't had any clearance problems. They weigh 20.18 lbs each. I'm running Michelin Pilot Super Sports in a 275/40-19 and they stick out past the wheel. This particular tire is really wide for some reason. I could have gone with 285's but they were 2 lbs heavier each and only added .4 inches of tire patch so I chose the 275's to save the unsprung weight. Glad I did because I can't imagine how far out past the wheel the 285's would go. The weight of the wheel with tire, balance weights, TPMS etc. is 49 lbs. And this is a 10" wide wheel. The factory SS 20" wheels are 62 lbs in the front; 67 lbs in the rear, so the weight reduction is significant.

The real challenge is finding the tires in the sizes you want for a 19" wheel. There are many more choices now than even just a couple years ago so it's much better but you may still have some challenges. The NT05 comes in a 275/35-19 but that would leave a pretty big wheel gap in the fender well. You're already losing an inch by going down to a 19 and the 35 profile lowers it even further.

These are the 275/40-19 Michelin PSS on mine, and I have my car lowered with Pedders coilovers:

Size:  425.1 KB

I had them painted of course (they come in silver normally) but you can certainly feel the difference when you take that much weight off the corners.

Other than these you're going to have to spend a lot more to find anything close to them in weight.

To compete with a Z28, you will need Z28 sized wheels & tires,19 X 11 front & rear,they may be even different offsets.$$$$$$,Oh also need Pedders!

I run Forgestar F14 18x10 all the way around with 285/40 18 Goodyear Eagle F1 Supercar tires. The tires are a little heavier than I would like, but they were stupid cheap so I decided to try them out.

I got the wheels and tires for under $1,700. They are about 50 lbs lighter than stock.

What offset are you running for your 18's? I like your setup and I would love to run it. Have you lowered it at all or is that just from the 18's?

I'm running 38mm all the way around so I can rotate them, but you have to be careful. I calculated this offset with other tires in mind so they would tuck as far in as posible and then bought these Goodyears at the last second. The sidewall on these Goodyears bulges out way more than the tires I planned on running so I'm having to use a small 5 mm spacer up front.

I'm either going with different tires when these wear our or I may just buy coilovers and get the extra clearance with those.

I'm also lowered about 1.5".

Do you think a 20-25mm offset would work? I want to run the same all around and run 275/35R18 BFGoodrich gforce comp 2 tires.

They will poke out a bit. I would stick with a 35 mm offset if you are going to run a 275 tire. Also, you do realize that a 275/35 18 tire is only 25.6" tall, right? Your car will look very goofy with those tiny tires. You can lower it to help the fender gap, but the over 3" shorter tires will lower your car 1.5" already. Lowering it even more to minimize the giant fender gap you will have will make the car too low and you will scrape everywhere. Ask me how I know.

This is the reason I got rid of my 26" tires and stepped up to 27" tires. I'm used to driving very low cars but the 1.5" drop from the wheels and the 1.5" drop from the lowering springs was just too much for even me.

Sorry I looked at the wrong size. 275/40ZR18 bfg g-force sport comp-2 tires. Will that be better. And I am going to upgrade the suspension to the stage 5 pfadt coilovers. I don't really mind if they will stick out a little bit.

Yeah, those are about 26.75. A lot better, but still have to get used to driving a very low car after you drop it.

Do I have to shave the hubs to fit 18's? If so I think I'll just stick with the 19x10 +25mm Enkei RPF1 wheel's and run the 275/40 or 35ZR19 tires. I will be running it on the autobahn and the Nurburgring in Germany next year.

If your looking to do any AutoX dont get the BFG G-Force Comp II. They suck for that. Great on the street but can't take the punishment of the heavy cars cornering. We have four of us in my local SCCA who got the same tire and we are having wear issues. I have severe cupping or feathering on my SS and so does one of the V6 guys. I am running the Pedders Race alignment so that contributes. I'm looking at the F1 or BFG Rival next. Really liking the Rivals but trying to fiure out sizing and wheel needs first.
Sux2BU, that price you quoted for your setup, was that for wheels and tires? If so, where? I'd like to go square also but thinking of only dropping to 19X10. I've been following this thread so thx for your input.

i was thinking about getting a similar set up over the winter for next season. i plan on hitting some auto-x and HPDE type events. probably gonna stick with 18" wheels and some nice sticky tires since they are just gonna be for track duty. i think ill either go with 18" f14's or 18" Nurbergrings...depends on the cost vs weight situation. and ill probably end up with somewhere in the 275 to 295 area Nitto NT05's.

It depends on the offset and width. I outlined when you would have to grind and when you wouldn't in this thread

Yes, that was wheels and tires. I got my wheels from Nineball on here (DV8motoring.com) and I got my tires from Discount Tire (they price matched am online price I found).

Tire price thread
http://www.camaro5.com/forums/showthread.php?t=216800

The good thing about going down to 18s is that the tire choice is insane and the prices drop drastically. 19s aren't anywhere near as common as 18s do the tire selection and price is more in line with 20s.

I was looking at the same wheels for my car. The Nurburgrings are cheaper, but don't come in the wide selection of widths and any offset you want, so I went with the Forgestar F14s. The weight difference is negligible, they are both super light

These guys have the Enkei RPF1 in the 19x10 witih 25mm offset for the best price I could find:

I just did a track day with these wheels and Michelin Pilot Super Sports in 275/40-19 and they performed flawlessly. The Michelin's stick out a bit; about 1/2 an inch in the front (fit perfectly in the back) because it's such a wide design tire but there were no rubbing issues, and I have mine lowered 1.5" with Pedders coilovers.

Even if you just get a set of these as a track set, the price is really good for such a light wheel (20 lbs) in this size. Overall diameter of the tire is 27.7" so it does lower the car about 1" lower than stock but it doesn't lower the car too much.

If you order from them make sure you tell them what car you're putting them on and ask for the correct size centering rings. These wheels also include the very nice Enkei Racing center caps.

You make very good and sound arguments Doc. Sounds like I'm stikkin with you on this one. I really appreciate the assistance guys.

Check my build thread out to see what comes next. I might need your help again. I'll update on here and on the build thread when I finally purchase and install my wheels.
