Just pulled the trigger on Fittipaldi FSF03 forged 19X8.5 35mm and 19X10 45mm. 2021 C43 coupe. I got a killer deal on them but they are blue, well not for long…. Going to my man James Terry for a refinish @MrSpeedCoatings. Tires will be Michelin PS4 235/40ZR19 front and 275/35ZR19 rear.
Never did post the results. 5mm front was perfect IMHO, decided to skip the springs. Real happy with the fitment and stance. The ride and handling with the Michelins is an amazing transformation. The weight savings helped too!
Nice looking wheel design. And another example of 10" wide with ET45 working in the rear. Any differences between coupe & sedan rear axle or fenders that allow extra wide wheels/tires?
Maybe I will go cheap and get those used Brabus wheels with PS4s already mounted and just replace the two rears with new, narrower tires. They will be heavy, but it will be something to use for a while as I get used to driving the car at high speed.
Hello, I’ve had my 2019 c43 Sedan for almost 6 months now and have decided to finally pull the trigger on a new set of wheels. The ones I’m looking at are TSW Neptunes and the size and offsets are as follows:
Front: 18x8.5 et +32
Rear: 18x9.5 et + 39
I know +30 front and +40 rear are said the be the limits in terms of offsets however I’ve seen on this thread that more is possible. My question(s) are, is this size safe to run in the rear? Could I possibly add 2mm spacers up front to bring it to ET30? And lastly what tire sizes would you all recommend for a more “meaty” look without having any sort of rubbing? Thanks in advance and sorry if I come off a bit uneducated (I am lol)

I probably wouldn't run that rear set-up unless lowered - just a little too aggressive and stretched tires with pokey rims on stock suspension is a pretty heinous look.

nothing considerably different. from everything I've seen they are nearly identical. Near enough anyways to run exactly the same setups.
I'm still learning, but those wheel sizes look fine. Best to get more offset and reduce it with spacers if needed.
[EDIT - Alexsas posted good pics, let that be your guide.]
By a "meaty" tire look, do you mean tall sidewalls or wide contact patch? People seem to stay with a conservative width up front.

my car (lowered) on 19x9.5et38 w/ 265/35/19
This is pretty much the fitment I want! I’m planning on lowering on kw has, so I should probably do that first then. Im not a fan of the stretched tire look in general; are you saying that stretching the tires is what is necessary for these to fit? Or simply that I should lower so that it wont be an issue? Thanks a ton

Thanks! I thought it would be okay but I realize I need to be lowered first. And yes I’m mostly referring to a taller sidewall, wasn’t sure what else to call it 😅

lower first. anybody wanting an even mildly aggressive set-up should lower first.
what you're posting will work fine (lowered) - as it's more or less the go to on this car w/ 235/40/19 front and 265/35/19 rear tires
I don't think they make 2mm spacer - smallest I've seen is 3. Which again - lends better to being lowered before getting those wheels. 19x8.5et32 SHOULD fit. We've had some members with slight issues rubbing the arms - this could literally be the difference in an alignment, etc. or small variances in manufacturer's measuring the offset.
Lowering basically gives you like 7mm upfront in extra space (to outer edge/fender). even more in the rear with the shape of the fenders on this car - which can look totally different from different angles.
for instance: you can literally see into the rear arches from this angle

Gotcha! I’m sure I’ll have more questions in the future but I appreciate the help so far. I’ll be sure to post any updates as I’m interested in hearing everybody’s thoughts.
Generally speaking, is the use of ring adapters to correct the center bore considered safe for track use? I assume companies make custom spacers that also correct for bore size.

I ask above question because I just found some wheels/tires that may work. I'm worried about poke on rear wheels again, should be 23mm more than my stock 8.5x18 ET52 wheels. Will test fit this weekend.
Enkie with 70 something center bore
8.0x18 ET45 (needs about 13mm - 15mm spacer)
9.0x18 ET35 (might poke too much)
They already have Nitto NT01 mounted with almost no wear! $1,000 !!!
This will be hard to pass up. I'm hoping the rears are OK and using center rings is OK. How do I determine the correct bolt to use? Obviously, I can figure the bolt length using my stock wheels and bolts. And I can tell a cone seat from a ball seat, but the proper mm size bolt for the seat? (Worst case, I'll offer $600 for the tires.) Thanks.

4 adults + big dip in the road might cause slight rubbing but for the most part you will be fine.
I was thinking Left Right Left Right during autocross. I think it will be fun to fling this mini-barge around the cones. I learned to autocross in a real barge, 1994 E420.

Also depends on the car. On my wagon, I feel a more aggressive setup in the rear compliments the look of the larger rear propositions. May not suit a sedan or coupe as much.
Wow, that looks perfect!
Can you tell me if those are OEM rims and if so where to get them?
I'm trying for the right set up on my C43 sedan and so far I have found not many great options. This is mine, stock as they come!

Thanks! They’re TSW Nurburgring. I was originally looking for SL63 rims which are the same design but forged and couldn’t find them for a good price anywhere. These were the next best thing (IMO)
I know it's almost 900 posts in this thread, but it is worth reading the whole thing. I strongly recommend it.
Based on posts in this thread, that would definitely hit the suspension in the front. Would need a 7 or 8 mm spacer, and that's a difficult size to fit/use (details above!). I can't comment on the rear as I never considered 10" wide wheel so didn't pay much attention to those specific discussions.

Thank you. What size of spacers would you say I should get to get some aggressive stance.
Depends on what ride height you’re planning to do. Et +30 is max on an 8.5” width front lowered on fixed springs without poking. More aggressive than that you risk rubbing the fender and not just the inner liners. Less aggressive than that your tire will rub against the knuckle.
