The rear, I expect a little more traction with 255 R compound vs 265 summer tire, which will allow me to accelerate out of turn a little faster, but will have to be careful of rear tires braking loose. I have had twelve track days in the last 2 years, and my goal is to come as close to 100% as I can to the capabilities of this car in stock form. Am not near that yet, and want to keep cars capabilities closer to my abilities. I am not competing with anyone, just out there to have fun. Will post the comparisons between the two set ups after my first track day.
Great attitude. I am very similar. When I sit back and take a breath I think 265 R compound rubber is more than enough for my driving ability and now it's about improving my driving rather than improving the car's speed which is ridiculously quick with the suspension, new rubber and tune. I share your concern with the rear end being a bit loose with the sticky square setup. I think as long as I be diligent about building speed, I can approach the tires limits and see how far my ability can take me, until I get more experienced out on track. My goal is to be driving competently at speed for every session with DSC Off, meaning I'm controlling traction on each corner and in control at all times - I think traction control is helping too much at present and probably holding back my development. All the best with your track season - I can't wait for summer!

Thanks, can't wait for track season either, wish I was in a warmer part of the country instead of the Northeast. As far as 9.5 wheels go, If I find I don't like having not enough rubber for a square set-up, I can always mount a 275 on the rear as a 9.5 wheel will be OK for a 275 tire, and go back to an 18" staggered set-up with the 255 on front, or move up to camber plates and suspension upgrades.

Buy some race team's scrubs. That's what I do.

Especially for HPDEs? And lap time is not the ultimate goal? Can't beat a set of 275 R-Comps for $300. Find a local BMW CCA Club Racing team that runs the M2 and you're golden. They'll ALWAYS have post event scrubs they can't or won't use for the future, and they'll gladly part with it for beer money.

True but earlier in this thread ZM2's view was a 275 on an 9.5 "won’t net you anymore contact patch and will increase sidewalk skirm and worsen turn in/steering response"... but yes it'll get you back to a staggered setup at least.

I can echo what a lot here have said. I started to track my M2 last year and I'm using Apex EC7 9" ET31 up front and 10" ET33 in the back. In my first year I didn't make the coilover and camber plate investment so my experience would be slightly different to yours.
I stuck with standard widths on the rims so that I could run them in stock class for autocross.
On the apex rims I run the 71R's staggered (255 front and 275 rear) and like many have said they work amazingly on the track. In my first track day I was moved straight from Group C to B and in the middle of the year they moved me to Group A. With no camber plates I had to several cool down laps per stint or I would have destroyed my tires. I spoke to quite a few people with M2's in the club and while they run RE's, none can make them last an entire season.
I couldn't find anybody running the RS4's on M2’s, but I was talking with two people (one 996 C2 and one Mustang GT) and both are able to run their RS4's for at least a season. The Mustang being a similar weight and power I would say it's pretty comparable.
With cool down laps, I could only make the RE's last for 3 events so I am going with Hankook's this season.
Btw I saw you are using Pagid pads, that's an excellent choice. I use them as well! I would suggest only running them on the track because their noise level is ridiculous.

How many days did you get out of your RS4s so far? AutoX or track days?

I had a Mustang GT as my track car before, and I ran RS3. I got 2 full seasons out of them of 3-4 track days per year. It was a popular tire with the Mustang crowd, and from what I heard the RS4s wear similar to RS3s.

I'd love to get them for the M2 but I don't think they make them in 255/275 - 19 combo.

About 8 track days on 2018. They have at least another 8 days left. Great and relatively cheap tire. I went with staggered 18s.

I should have mentioned that my apex rims are 18" and they do make the RS4s in that size.

Thanks! I’m very curious to see how my new square setup feels this season... there’s such polarizing views on this forum on running the M2 staggered vs square, everyone seems firmly divided.. looking forward to finding out for myself. The car was very impressive on the stock staggered setup so will be interesting!

How did you find the setup?

And if what you are saying about storing the RS4's is correct, maybe i just go all out and opt for the RE71's if I'm going to be replacing them after a season... hmm..
FWIW, the Apex Wheel Showroom Gallery Thread on the Wheel and Tire Section lists several modified M2 running 275 tires on their 9.5 wheels. I do not have any experience running this wheel and tire, but will looking into it down the road.

Lots of people do it, doesn’t make it better than 265 square on a 9.5” wheel.

And, square vs staggered is really just a cost decision, plus it will lead you down either the 18” or 19” path.

The car will always be faster if you can go staggered and get 285-305 rubber in the back. There just aren’t many good 18” options for such a staggered setup. So, 18” is about running a cost effective square setup.

Both paths are good, it just depends on which you want to take. I’ve done both.

On my 17 M2 I'm running the following tire and wheel setups:

1. Winter = square Michelin PA4 snow tires 245/40-18.

2. Track = staggered Hankook RS4 245/40-18 front and 265/40-18 rear.

3. Summer = OEM = staggered 19" Michelin Pilot PS4s 245/35-19 front and 265/35-19 rear.

That's close to what I did when I used to track my 97' E90 335i. I bought an endless supply of the Bridgestone summer performance runflat tires and burned them up on the track. On average each set of tires cost me about $200 and all were new or only had a couple of hundred miles on them.

How do you like the RS4's? Any experience with RE-71R? Would be interesting to hear an opinion from somebody who tracked both.

Plenty of opinions in this and other threads. Bridgestone are faster, Hankooks are slightly slower, but will last longer. I plan to try both this summer and decide later if the additional cost or running Bridgestones is worth it. It probably isn't though; Ultimately I am at the track to have fun and be safe, not try to squeeze out every possible second of time.

The RS4s are great. Long lasting. Super stiff sidewall. Ok, but certainly not great in the rain. It is the best tire for me. It is relatively inexpensive and it certainly wears much better and longer than the RE71Rs.

Thanks Rich, good stuff. This setup sounds similar to what i'd like to do, though my preference would be to go slightly wider for track duty.

In my present situation I do not want to to buy/store additional rims (no garage, just 3 parking spots in front of the house) so I'm leaning towards 255/35-19 front ans 275/35-19 rear. This way I keep the factory understeer/oversteer characteristics by keeping the contact patch ratios the same, and it should fit on factory rims.

5 monster - consider going 265/35 and 285/35 on oem rims. This is as wide as you can go and can get re71r in this size. This is the setup I'll go for this summer.

Thanks man, I'd love to go that route! My issue is that it's tough in Germany to make ANY kind of mod. My registration states the tire size right on it (factory 245/265 setup) and a shop I took it to already told me that's the only thing they are allowed to put on it.

So I'd love to go wider, but I'd be happy with 255/275 if I can even pull it off.

P.S. For street dudty I wouldn't care, but 265 is right on the edge of what the tire mfg recommends. I'd be worried about sidewall rollover to be honest. I've seen the shoulder wear on my stock 255s and 275s on wider rims with my previous track car. They are not joking.

255/275 or 255/285 is they way to go for the track on stock rims, if they’ll let you do it in Germany.

265/35 on the stock 9” rim doesn’t net hardly anymore contact patch and introduces worse steering response and rollover on track. Really need a 9.5” rim for a 265 on track.

Plus, a new 265 is taller and will rub the fender liner under severe compression, which you’ll find on track.
