RS4 can be had in 265/35/18 F and 285/35/18 R. Alternatively you can have 275/40/18 F and 295/40/18 R but I am not sure the fronts would fit.

RE71s are an option at 255/35 F and 275/35 R but will be very short. If you go 19" rear wheels you can do 18" fronts with RE71 at 275/35/18 F and 305/30/19 R.

I’m running 265/40-18 and 295/40/18 Rs4s and love them! Fit great on my Apex 18x10/11 setup... did they discontinue the 265fronts already???

wow, but are you lowered?

No, but the 40series 18s have the same Diameter as my stock ZCPs.. I will have to look up the exact difference, but it’s a fraction of an inch tops

Stock front 26.3”. -Rs4 26.2” diameter

Stock rear 26.8” -rs4 27.1” diameter

Wanted to go 275/40 fronts, but I chickened out without anyone else running the Rs4 yet, I wasn’t sure how close it’d be with the extra 1/2” in width. After running these, it looks like it’ll work... close enough I’m gonna try it for my next set.

Trying to maximize the TTSA for this setup to get the most I can from the tires...

My goal... Smallest wheel diameter to clear the brakes, largest diameter widest you can fit and keep balance. Our cars are front tire limited on track imho, (yes, you can overpower the rears, but I’m talking balance) so a 275/305 would be about perfect, but couldn’t find a 305 18 outside of a pure track tire... so 295 it was!

Anyone try the MPSS combo on the track with camber plates? For the money, wouldn't the PSS be the best bang for the buck and would be a good choice if it were to rain out there? Currently I on the the RE-71 but on stock 19, I'm looking to tire up my EC-7 18x9.5 and 18x11. The NT01 seem like a great choice however not sure if they would last long at all? The RS4 don't seem like a bad compromise but they are heavy and the overall diameter for the choices seems a bit off. Would DSC intervene more with the larger difference in F/R diameter? Anyone try the RS4 265/35 295/40 setup?

Great set up, but I haven't compared to a square set up in my F82.

If you're going to get these wheels and plan on coilovers, just be careful about what size wheel you put up front. Some popular sets like KW will interfere with your tire if they're 10" or bigger.

I'm thinking of adopting this setup above. I'm wondering if anyone has gone with a front 18 x 10 ET22 with NT01 275/35/18 combined with the M Performance HAS suspension (and can confirm no rubbing). Or - is the performance difference between a 9.5 width front wheel vs. a 10.0 width wheel (assuming both have NT01 275/35/18 tires) so minimal that I may as well "play it safe" and go with the 9.5 width if going with the M Performance HAS?

I would do RS4 in 265/35/18 and 285/35/18 if you really want RS4. That will give you more width than stock. You can run them on the EC7 wheels you have above safely. If you decide after a season to move up to NT01 that will be an option. Lastly, why don’t you check out the NT05? I am going to run the NT05 275/35 and 295/35 on 18x10 and 18x11 EC7s this year. I will let you know how they do in a few weeks! I am coming from RS3s. The NT05 are reasonable enough in price (in the grand scheme of things) that I planned on giving them a shot. Not mentioned a lot on BMW forums but good feedback on other forums.

265/35-18 and 295/40-18 would be a huge spread for diameter. Go with the 265/40-18 and 295/40-18 (what I'm running) if you want the 295s...

Last time I checked the 265/40R18 wasnt an option at Tirerack anymore.

I have thought about this as well but no info please post after you use this set up will be very helpful!

I thought about this but the tires overall diameter will be almost an inch over stock and the weight is heavy on those tires , how are they? Can you feel the weight ?

Nice to know they have them back! A month ago they didn’t!

they are comparable in weight to the NT01 or R888R or Re11 and very close in weight to RE71.

MPSS are lighter but it's because they are not in the same category of tire.


only tire in the same category as above potentially is PSC2 which is the lightest one I've seen to date. but in 18inch few sizes exist

JRZ RS Pro with Eibach 450/550, Dinan Toe Link, Fall Line Mono Ball and rear end bushings, Brembo GT Type 3 front and rear 380mm, Endless ME20 and MSi Racing.

Just FYI, the JRZ RS Pro do not require front spacers unlike the KW Clubsport to clear the front wheels.

Forgeline GTD1 Square 18x10 et 27 NT01 275/35/18. I prefer the square set up over my staggered because tires are not cheap. Yes, I'm at the end of my front rotor life and I'm planning on giving the Brembo RE10 pads a try.

How much clearance from the JRZ RS pros do you have with you setup up front?? I see that you have ET22 up front so I was wondering if 275 tires on 10" wheels ET25 would fit?

MPSS are lighter because they have significantly less tread width compared to the others.

I run this exact setup with 275 NT01's. Clearance between the front tire sidewall and spring perch is about 2mm so I run 3mm spacers to be safe. There is a thread discussing this where I added some pictures, do a search and you should be able to find more info.

I posted the diameter compared to my stock zcp setup a bit above in this thread. 0.1” smaller od up front an 0.3”larger od rear.

I didn’t notice the weight as I went from the stock 20” zcp setup to these on 18” apex wheels and lost a fair bit of weight on each corner. I could feel that!

Hi all!

New to the forum, am driving an M4 ZCP! I have had a huge headache on what kind of a track setup to run. I am not looking to run a 10X18 square setup as I would have to go down from 285 to 275 tyres in the rear and grip is a priority for me.


Would it be advisable to run Enkei RS05RR's F 18X9.5 ET22 R 18X10.5 ET23? My main concern is the offset for the rear rims, which is much more aggressive than the recommended ET32-37, would this lead to any issues?

Thank you!

Your fronts are not the recommended Apex setup i believe. They usually do 18x10 for fronts.
