Wheel gurus! I've got a new set on the way and need a bit of help.

[NickyC]

Hey hey, with spring coming up I thought I'd put some new shoes on the M3. The prior HRE FF04s were fantastic on my two M4s, but I've always liked the look of the FF11 a bit better so I bought a set and they're coming I think on Thursday. I never ran spacers on my prior sets, so I wanted to get some advice from the gurus on this forum as you guys know everything. Anyway here are the wheel/tire specs:

FRONTS: 20 X 10 INCHES
OFFSET: +23

REARS: 20 X 11 INCHES
OFFSET: +43

TIRES SIZES:

FRONTS: 275/30ZR20
REARS: 295/30/ZR20

Currently I'm running the 437m wheels with a 10mm spacer front, and a 5mm spacer rear along with KW V3s (and brother she's low). My question is, am I going to be OK with those spacers along with the new wheels/offsets on a dumped car or will the spacers have to come off? I'd love to have the bit more flush look of course, but if it's going to create a PITA to get everything setup correctly again I think I'll just dump the spacers. BTW I really like the 437m wheels but going larger sized tires with the corresponding larger sidewalls has caused quite a few issues with such a lower car. I'm soon to be on my THIRD lip in under 1k miles of ownership so I think going with 20"s and proper sized tires will help a ton. I also want to get rid of the slight gap I have in the front right now and make it look more like my F82 (if I go any lower in the front now the car is a plow and I can't get over anything).

Any help would be greatly appreciated! BTW I went with the liquid metal instead of satin black as I've never liked black wheels on a black car (but like black wheels on every other color car hah!).

Third picture is my prior car with the FF04s and NO spacers. Bottom picture is my current car as she sits. I want the tucked look again, so wondering if the spacers are going to put me in the fender? I think the offsets between the two wheels are the same but can't remember exactly. Thanks for the help!

Here's the front of my F80 with 20x10 et17 and a 265/30/20 PS4S tire. A 275/30/20 will rub the liners like crazy when you turn the wheel. If you're low enough, it'll rub/hit the fender. Doesn't look like you're that low though.









Here's the rear of my F80 with 20x11 et36 and a 295/30/20 RE71-R and PS4S tire. Tire only rubs the liners a tiny bit on full compression. It "may" rub the tab where the rear fender and rear bumper meet -- you may need to trim that down. I did.

[NickyC]

Thanks for the help, beautiful car!

So I think what you’re saying is the spacers are going to have to go?

I don’t think our setup is matching though. I had 275/30/20 on the front with prior setup and never had a single rub.

[dms-01]

Yeah 275 is a no go on the fronts on M3s. Doesn't even matter if you are that low, my car at this height will rub in the front on the liner where the side view cameras are on full compression.

FWIW fronts always rubbed on 265/30/20s on C300s and LM-rs on both spring and coilovers (same as you kw3s). I would just get 265/30s and deal with what little rubbing you may or may not have, I would never try and make a 275 work on an F80 based on the fact I hate rubbing and I don't think you would ever not rub with 275s.

Thanks but these wheels are sold as a package with 275/30/20s in front specifically for the car. TAG for instance sells that setup on their website. Confused here.

Is the M4 setup differently than M3 in the front? My 275/30/20s never rubbed front on M4.

Did some quick searching, 275s seem ok. This guy has my exact setup and said: “It's an offset thing with a 275 as I don't know they are bigger section width than P4S. I'm ran P4S 275/30/20 on a 9.5 et22 no issue. I just upgraded to 10 et 23 with the same P4S tire. No problemo. It is crazy close to the strut but still no issue. Gotta love HRE”.

Definitely looks like spacers have to go though!

Here’s a link to TAG wheel/tire package as well. 275/30/20s clearly shown. Hopefully it’s the HRE offset which makes the magic happen. Find out in a couple days I guess!

275s fit better on an M4 then they do an M3.

And in TAGs picture that combo is on an M4 but that doesn't really matter. What matters is a couple things, 1 - 275s are a pain in the ass on an M3 and 2 - using a spacer would only make them worse. They are simply too wide of a tire for an M3 regardless of the width offset of the wheel they are going on. Maybe a narrow 275 but certainly not a PS4S.

PS4S:
275/20 is 10.9" wide 26.5" tall
265/20 is 10.7" wide 26.3" tall

So when a 265 rubs what do you think is going to happen with a 275? Its going to rub even more. But a lot of guys don't give a shit about rubbing so YMMV.

Gotcha thanks, the one thing we’ve learned is the spacers 100% have to go lol. Would suck to get the setup and rub right away but never expected the 275 would be an issue due to my history and the way the package is sold. I really appreciate the help however, I guess we’ll find out in a few days. Thanks again!

Found another place with the 275 recommendation. Maybe this is straight from HRE but hope they’re right.

[NickyC]

The answer is a BIG FAT NO.

Finally got a chance today to try the 275/30/20 et23 in front on the F80, FUGGIT ABOUT IT.

There would be massive rubbing on the fender liner, and even the fender itself would be at risk. Absolutely NO chance without major mods. How TAG got this one so wrong on their site is beyond me, but if any M3 owners are looking into this package do NOT get the 275/30/20 et23 option for the front. You should get a 20x9.5 with a 265/30/20 at the absolute largest.

Thank you all for your help on this, I hope it helps someone in the future. Now to put these up for sale for a lucky M4 owner!

[dms-01]

We told you man. And if it were me I would make TAG replace those 275s with 265s. Huge fail on their part and they should know better for being in the scene so to speak.

Yep, but I had already bought them before I found out here so wasn't ignoring the advice. Very disappointing on TAG's part though, they have the package clearly listed for an M3 and it's not even close. I didn't buy the package from them, but I did buy similar from them for my M4 which is why this is all quite a surprise.

I love these wheels though, maybe I’ll just get a new pair of 255/30/20s to be absolutely sure. They’ll be stretched but I like that look.

A 20x10 et23 with a 255/30/20 would be fine in the front of an F80 I’d hope? Thanks.

I would stick with a 265/30/20 F because you are running a 295/30/20 rear tire. If you drop down to a 255/30/20 front, the height difference btw front and rear tires would be noticeably greater than stock, which will cause more traction control interventions during normal driving. I noticed this issue when I increased my rear stock 19s to 285/35/19 paired with my stock 255/35/19 front tires (which were admittedly worn and likely exacerbated the issue since the worn tires were even shorter in diameter paired with the new 285s out back).

FWIW I am currently running PS4S 265/30/20 on 20x9.5 +17 rims on my lowered F80 M3 with zero rubbing issues at all under any condition.

Understood thank you for the help!

[dms-01]

Yeah stick with 265/30/20 with those wheels and you will be ok. Worst case you could always raise up your car a little bit as you have KWs.

My 265 RT660's are 10.9" wide and 26.4" tall... They don't rub at all and I have Ohlins R/T coilovers lowered most of the way. I could probably fit a 285 PS4S.

Just gotta have the right offset/camber.

265 what? 35/19? And without adjustable camber plates there is no right 'offset/camber' because we both know there is no camber adjustability in the fronts on these cars. And I doubt he (like the majority of owners) has any interest in buying front camber plates in the hopes of making 275s work or whatever 19" RT660 you are running.

265/35/19. The size the tire has on the side of it doesn't matter nor does the wheel diameter in this case, it's the actual size of the tire that does... The actual size of the tire that I have are are 10.9" wide and 26.4" tall, which is the same specs at the 275 PS4S you were talking about, which, according to you "will rub even more".

I didn't see him mention anywhere that he didn't have camber plates. From my experience, it is pretty uncommon to install coilovers without camber plates. Anytime you lower a car that much, especially when you want more of a flush fitment, camber plates become a needed mod. They really make all the difference.

[dms-01]

Did he mention that he did? No so your point is moot. And not everyone who lowers their car on coilovers needs or wants adjustable camber. So anyone can buy a wheel-tire that fits without the needed camber.


You want to go full send with camber and wide/tall tires go for it but you're the exception and not the norm of majority F8x owners.

[bigj505]

I found this user on IG. He has 285/30/20 up front and 305/30/20 in the rear. Maybe you can ask what he did to get it to fit.

Thanks, but where does he say he has 285 up front, another part of the post? I don't have IG or any social media shit like that haha.

I don't know I would do it, there was absolutely no room up front. We couldn't even put the car on the ground as the tire/wheel was already hitting the strut with the car jacked. I don't know if my KW V3s have anything to do with it but we weren't even close clearance wise. I'd have to put some massive spacers on there and roll the fenders or something to make it work, even then I'd be spraying the rear fenders with constant road debris.

[TR930]

I run 275 front and 305 rears not rubbing or issues. F80 m3. ACS springs. 19 inch wheels et20 front and et40 rear.

Thanks, I’m trying to use 10 inch wheels however so big difference.
