Post your wheel size, tire size - looking for the best track for set up c6 z06 If any one has any input Id love to get some feed back

AtomicZ

CCW, Finspeed, Forgeline seem to be the popular picks for track wheels.

I run 18 x 11 front 18 x 13 rear CCWs on my Z06(with coilovers)

Tires are 345/35/18 rears & 315/30/18 fronts.

How do you figure out what offsets to order?

AtomicZ

Bought both sets used on here.

Call John at CCW and tell him what you are looking for - he has made a bunch.

Check out Finspeed. Great wheels at great prices with many options. Sizes are the same as others have stated.

DSteck

Finspeed for sure. CCW was bought by Weld, so you probably won't be dealing with John anymore. Finspeed wheels are extremely well engineered one piece wheels. Super light, super strong, and pass cyclic stress testing with flying colors. They're also all cut to order... So you can completely customize the set and get as crazy as you want (and your budget can handle) with lightening options.

Thanks for the advice from everyone! Finspeed seems to be the way if they do custom stuff.

Do tires increase substianlty as rim size goes up?

Seems everyone stays 18 diameter vs doing 19 19 0r 19 20 like the zr1

I have a set For Sale if you are interested! https://www.corvetteforum.com/forums...and-tires.html
Give me a call, these came off of a C6-Z

Screamin Z

Everyone stays with 18" wheels for better tire selection. Imo anything bigger is unnessary for the track.

I have a set of Finspeed. Like new that I may sell. 18x11, 18x13 with Hoosier R7 (3 20 min sessions). PM if interested. Gunmetal black.

What shape are the rims - but I'm also unsure about the 11 and 13 specs- Seems most people are running 10 and 12 (for savings and for speed)

Question for thread
Is 18front and 19 rear terrible on the track or 18-18. 18-19 19-19 are just flavors I should pick what I like the most?

Rando question for the thread - if I run 18x10 from and 18x12 rear or 19x10 front and 19x12 rear - with front splitter and a rear wing (eventually side skirts and rear diffuser) can I then save cash on rubber by running really good street tires (wich I can drive home on) or are slicks substantially better/ way more fun on the track especially with down force

trj3

It depends on what you want to do. I have run stock staggered set up and it works fine. The fronts push a little. The 11x13 is a beast set up and works great. I have never run 10x12. Rims are near perfect.

univerz06

I wanna do auto cross, track days, hill climbs and time attacks (although im going to use the hill climbs and time attack as just fun track days lol) but I like a car on rails or as close to it as possible. I'm in love with the HRE p40sc wheels but the smallest offered is 19. Finspeed f14s concave version are my second fav and come in tons of sizes. That's said, Id rather have better perfomance than my favorite wheel.

Budget wise is the 18x11 18x13 set up difficult to find rubber for? I'm kind of hoping to run a good street tire and down force instead of running slicks (so I don't have to have change tires out every track day)

Are 18x10 18x12 cheaper?

RichieRichZ06

Finspeed FTW!

univerz06

Those rims are what I want - if 19front and rear is detrimental to perfomance and rubber budget then those are the ones I want with the concave and everything

univerz06

By shape I meant are they f14 f11 like what design are they lol - im after f14 concaved as they can be. I can just buy them direct from finspeed unless you happen to have what I'm after I don't mind saving some change buying used (and helping a forum member out)

Actually I talked to John when I sent one of my CCW C10s back to them to be checked after an on track incident at the end of June. He is still there providing his excellent service.

Ditto on the CCW and tire sizes. As prescribed, John at CCW just several weeks ago set me up with offsets etc.

parsonsj

Same here, on Forgeline GA3Rs.





I've also put in .400 travel limiters on the rack to keep the front tires out of the brake ducts.

One other thing about wheel sizes. Bigger wheels cost you in performance. I'll spare the physics, but wheels are big rotating masses, and the bigger they are, the harder it is accelerate and decelerate. A decent rule of thumb is to think of them like weight. Each inch of wheel diameter is about equal to 50 lbs. So 4 19" wheels makes the car "feel" as if it weighs 200 lbs more than the same car on 18" wheels.
