18x12" rear wheels with any of the offsets listed in this thread will fit without contact when the vehicle is at ride height, and when you're jacking up one side of the car at a time. The contact only occurs when both sides are off the ground (the suspension isn't bound up anymore, allowing it to droop down further). Multiple on-car tests in various scenarios reveals this, grabbing offsets off the internet does not.

The question regarding 18" vs 19" rear wheels has come up a lot lately, so I'll share what I've told everyone else so far who has asked. In my opinion it comes down to what tires you want to use. The performance difference from running an identical setup with an 18" rear or 19" rear is negligible if any. But many tire combos are not as easy to come by in certain sizing. If you want to run slicks, 18" front and rear is a no brainer. However, many popular 100 and 200 TW tires come in the 275/35-18 - 325/30-19 setup, which is perfect for 18x10"/19x11.5".

Hoosier R7’s still the tire of choice for weekend track events? Is there a recognized best option for performance & longevity before going to the 200 TW club? It’s been a couple years.

Hi there what wheel brand and tire are you running? I'm doing mostly SCCA events I'm wondering if they will make move classes if I go to an 18" in the rear. I believe we can only go up or down 1".

I'm currently running a 9.5 x 19 275/35/19 Sport Cup 2 and 12 x 20 325/30/20 Sport Cup 2 but they got me for 180 TW tire. Need a cheaper alternative.

Thanks
Brent

Are you running in SSCA street class autocross, or their track day/time trial series?

Our 18x10/19x11.5" combo has been very popular for track day customers for a few reasons, but most importantly there is a massive selection of tires available at much better price points than a 19/20 combo. Forum member AHP just setup one of their cars with the following:

VS-5RS Forged wheels finished in Satin Black
Front: 18x10" ET42 with 275/35-18 Continental ExtremeForce
Rear: 19x11.5" ET48 with 325/30-19 Continental ExtremeForce

This setup retails for $3,196 and is currently about 6 weeks out for more. They are not made to order, we just happen to be out of stock at the moment but more are already in production!

Are you guys considering an 18x10.5 front option? I'm guessing we'll get the best performance out of these cars with 315 front tires, and 10.5 would support that. I suppose 18x10 does, too, but it's a bit too narrow at that point. Thoughts?

Default MRR Forged F43 wheels for Track

why wait for custom track forged wheels? when we got them in stock ready to go.
This is our Forged F43 model as posted above the threads before
18x10 front and 18x12 rear, will accommodate for a huge variation of tire sizes
zero mods required, straight bolt on application.
Here's one shown in our Gold color

Perfect offset fitment on the MRR Wheel. A real homerun by Carlos and his team. They have been abused on track, hit a bunch of curbs, jumped a bunch of curbs... they are a strong wheel. Been putting them through their paces for some time now!

There are no plans for a wider front wheel for the narrowbody C8. 10" is pushing the limits already with a 275 mounted without major changes. People are running 295s on them as well but it rubs the inside on compression, which is okay as it's cosmetic only rubbing.

Have you seen a narrowbody C8 run 315s up front? That's asking quite a bit from it.

That said.. Super pleased with the quality, fitment, looks, etc.. of the Apex wheels! The 18/19 combo really broadened the available tire options for a dual purpose car.

I have not seen any narrow body C8s with 315s up front. I'm ordering custom forged wheels at:
18x10.5 front, +52,
19x12.5 rear +58.

I will try them along with track alignment, MCS coilovers, and 315/30/18 front, 345/30/19 rear R7 tires. We'll see how it all works out!

Note: I made it work for C7 Z51 at the time:

10.5 + 52 is going to stick out in the front. I had that set up and used some C&z front spats to make it work. I have since went to a 9.5 front rim with a 38 offset and it's even. 275 front Goodyear SC3.

had to make some brackets to hold the spats. basically some industrial velcro did the trick.

18x10.5 +52 is tucked in more than APEX's 18x10 +42 wheels. If anything, I'm way more inside, and this will limit the lock-to-lock movement. Here's hoping it only becomes an issue for parking maneuvers. I'll be using at least -3 camber in corners; this should also help.

I've also ordered a set from APEX 18x10, 19x11.5, and intend to use them for less aggressive tire fitments and street use. Looks like I'll have everything before the car itself; oh well : )
