I am narrowing down my track set up and I am leaning towards 19x10.5 and running 305's. Is it correct to say that your fitment guide is based on stock suspension and not lowering ~1" via a HAS? TIA

There are notes for that fitment with aftermarket suspension, but we haven't tested every single combination of tires and suspension listed on the fitment guide at different variable ride heights. HAS kits in general limit inner clearance around the front suspension more than the stock dampers. You'll need wider spacers and the 19x10.5 ET18 fitment, in particular, takes up quite a bit of room in the front wheelwell, especially with the 305 tires.

5mm spacers would be my minimum recommendation in your case, but the harder part is going to be getting this front tire to clear your front fender liners when turning lock to lock if they are still stock.

Looks nice Tom! Why you guys cheating on me!

Kidding... I was going to post photos in "what did you do to your G87 today" of my ceramic coated 20x11's... DIY of course. Should be getting them on this week!

One M2 is never enough! Looking forward to seeing them on your car.

I'd like to reuse my stock tires (PS4S with the *), would they fit with this setup?

Our front wheels in the staggered diameter setup (19x10 ET12) easily fit the factory 275/35-19 tires. The rear 20x11 ET18s are less ideal. The factory 285/30-20 tires are going to be stretched on the 11" wheels and lack a bit of sidewall support. It's probably fine to use this fitment to wear through the OE set of tires, but I'd recommend going wider once the stock tires have worn through.

My 305/30R20's are mean looking.

Tom, would the 20x10 ET8 work with the factory 285/30-20s?

They would be fine to run, but a half-inch narrower than the OE wheels. Unlike the 11s this setup wouldn't give you the lee-way to go wider in the future without compromising sidewall support.

Got it. There's a local place that is a vendor for you guys. I can order from them to support our local business. Sounds like I'll do the 20X11 in the back and the 19s up front to get close to stock sizes.

Heres an example of how that stock tire setup looks on a G80 with the 285 on the 11. Definitely a bit of stretch but not that bad to my eye:

Would a 19x11" ET22 square fit with some camber in the front?

That would be an extremely aggressive fitment. It can be done, but you'd need quite a bit of camber, aftermarket or modified front liners and thick spacers, 12mm at minimum. Jackie Ding runs this setup (19x11 ET22 square) and I believe with the OE dampers he's running around a 12mm spacer.

If gold wheels are a fad then I don't want to be in style.
Here is my M2 with 19x10.5" square VS-5RS

GT3M2 · 09-02-2023, 10:54 AM

18x10.5s mounted.

295/35R18 Nankang CR-S.

So far no rubbing but haven’t got it up on lift to check, turn in feel is incredible with the wider front, cannot wait to throw some camber at it.

49.75-50.15 lbs per corner 👍👍👍

What tire size did you end up running? I'm having a tough time reading the sidewall.

Love these setups guys! For my own reference, were spacers required with either car?

Thanks for picking up these sets!

295/30/19- I bought 5mm spacers but I didn't need them. I will keep them in case I decide to go 305's down the road.

Nice, that is good to hear. It's also good to see that the CR-S is getting more available as well. For a while, it was hard to source those and recommend them to customers but I saw they were added to Tire Rack recently.

Tom I am running the 5mm spacers you guys sent me but as far as I can tell they are not necessary and 0 rubbing at full lock yet, track this weekend.

Will update after weekend.

Stock height, only changes are wheels and tires.

I know this is less than ideal question as its personal preference but thinking about buying a set for the track, what is everyones thought here? Cost wise and performance.

go for 18's? and staggered setup? I have some camber plates and KW HAAS I am throwing on there. Thinking of keeping the 20's for "street" and getting a second pair for the track but hard time deciding what I want.
