I've easily fit 275/35/18 up front, even 285/30/18. -3 camber stock ride height.

He was talking about fitting a 275/35/19 up front.

The 71R's are easier to drive at their limits in the wet, and are somewhat faster... The Rival 1.5's are faster in the dry. Look at National SCCA Final results in in the ST classes.

The Rivals IMO are a better all around tire on a dual purpose car..,..

Even if the Rival is barely quicker in the dry for your particular driving style and setup (while being slower in the wet), you won’t be able to fit a 275/35/19 up front.

And, the Rival is much more twitchy at the limit. Not really what I’d want on a track, where the speeds are higher than autox and smoothness is rewarded.

But, if you make it work, post the pics for everyone. I’ll have pics of my 265/35 305/30/19 71R setup later this month.

How are you so sure the 275/35's won't fit?

3.5 degrees of neg camber on 19x9.5's and a small spacer should work fine...

305/30's on a 10.5 with 2.3-2.5 Neg Camber and a fender roll should fit in the back as well.

The Rival 1.5's are, and have been proven time and time again to be the fastest 200 AA tire in Solo 2. The problem is it requires much more skill to get everything out of them vs. the RE71R's.

I like both these tires, but the really loud road noise and quicker wear of the RE71R's has me 100% in the BFG corner...

Well, truth be told, I don’t care much for autox, so the track is my focus. The 71R is much more predictable at the limit than the BFG, which is more impt where the corner speeds are much higher on a track, and that predictability leads to faster times on a real track where there are a lot more things to hit than just cones, esp in a $60k car, vs a Miata.

The issue with the 275/35/19 is the height, not the width. You’ll rub big time with even slight compression. Even 265/35/19 rubs until you’ve worn the tire down some. But you seem like the hard headed type, so give it a go and report back to everyone.

Also, you don’t need more than -2.0 in the rear on the M2 to achieve good wear. You’ll instead lose acceleration traction and slide the tire more and wear it quicker. And, you don’t need to roll the fender (again, $60k car!) to get the right fitment. I’m pretty much the guy that forced Apex to go to +45 in the rear bc I kept hounding them that their originally proposed offsets wouldn’t work for some 295/305s. I’ve been running +45 in the rear for a year.

But don’t listen to me, I’m just some guy that has no idea what he’s talking about after 40+ track days in his M2 over the last 2yrs.

Lastly, the OP was asking about tires to mount on his stock wheels. I gave the best answer to his question in the very first reply, vs all this 71R vs BFG Solo2, too tall tire, extreme camber, rolling fenders, aftermarket wheel discussion.

Appreciate the input...I don't even have my M2C yet....so all this is very informative...THX

I agree that the slip angles on the 2 tires are different and that the Bridge's are more forgiving at their rolling to sliding friction transitions.

But both these tires aren't even in the same league as a BFG R1 or HOHO A7/R7 for slip angles and feedback. I say that because both the aforementioned are 200 wear street tires and are much easier to drive up and over their limits than a R compound track only tire.

I state this from my own experience as well.... having over 200 track days in 2 different M cars and a EVO X over a 30 year period...

On R compounds both the M's liked 2.2-2.4 degrees in of neg camber in the rear with 3.4-3.7 up front. That was verified with both a pyrometer and a AIM SOLO 2 on HOHO's and BFG R1's. Also with a dialed in spring and C/O setup.

I'm sure those camber numbers will be lower on 200 wear street tires like the RE71R's.

I wonder if anyone has tried the 275/35/19's up front yet?

There are 2016-18 M2's on them in the 18" size...

I'm trying not to have to spend $'s on the Essex BBK kit if at all possible, but if what your saying is the case then that's exactly what I'll have to do next Spg, and buy some 18" rims and mount BFG R1's in 275/35/18's on all 4 corners. That should be a wicked fast square setup!

Keep the shiny side up!

I hear you regarding the slicks.

When I ran 265/35 & 295/30 R7s on my 19x9.5/10.5 setup, the fronts wanted more than the -3.1 I had dialed in. The rears were pretty happy at -2.0, tho. When I’ve tried -2.2 in the rear, I couldn’t get the backend to hook up as good. But, when we’re talking tenths of degrees, track layout, conditions, suspension setup, and driving style will all impact those settings.

After running thru tons of 18 & 19” tires on my M2, I’m landing on 265/35 & 305/30/19 71R as the best performance bang for the buck I can find at the moment. Hopefully we get more options as 19” track tires get more popular.

That's great advice on your staggered setup. I've started to pester BFG to make some R1 & R1s in 19" sizes we can use. The R1 is my all time favorite r compound DOT tire.

BTW true slicks are even more difficult to drive on vs DOT R compounds. They all have very square sidewalls and have very small slip angles. User beware. I ran some YOKO's several years back...Went right back to DOT R's after realizing they aren't worth the hassle and quick wear for only marginally faster lap times.

Why not use MPSC2?

They are, but they are also quite expensive and wear out quick on the track.

But they do the job in a good way. I don’t know any other tire, which you can drive on the racetrack and at the same time be comfortable on your way home from a racetrack.

My car is on stock suspension now. I expect to install camber plates next year, and will likely end up mounting these RE-71Rs on a dedicated set of EC-7 wheels (9.5/10.5). I do not plan coilovers or HAS anytime soon.

I checked w/ Apex to confirm fitment of 285s in their EC-7 rear, and they responded "A 285/35-19 is 2.05% taller in overall diameter compared to the stock M2C rear 265/35-19 rear tire. With an aggressive tire such as the RE-71R there could potentially be scrubbing issues on the rear fender due to the height of the tire and the more "beefy" shoulders that those particular tires have. It might be something you could potentially run on a stock ride height car, however it isn't something I can guarantee a perfect scrub free fitment with."

I'm hoping to confirm that ZM2 experience was with similar stock configuration. I really want to avoid any rub issues. If there is a small chance of rubbing on compression, I'm fine with my original plan of 275s in the rear.

You shouldn’t have any issues with 285s in the back if you’re on stock suspension.

Basically any other 200 rated extreme performance summer tire. Hankook RS3 and RS4, Bridgestone RE71R. Advan AD08R, Star Spec II if you can still find them, BFG Rival.... a lot tires fit this description. My money is on the RE-71R for my next set on factory rims.

I run this RE71 setup on the 19" EC7s and am lowered on KW v3s. I did have to raise the height a bit in the rear to get the 285s to work, but on most tracks I haven't had any rubbing.

Thanks for the replies ZM2 and wanofakind01! I'm leaning toward this setup for an upcoming HPDE weekend. Will post afterward for any members interested in this tire combo.

Hi, I drive 265/30 R19 front and 295/30 R19 rear. Both Pirelli Trofeo R, it is the best semislick on market, was driving on many semislicks and this is the top by my taste.

3,2 camber front; 2,7 camber rear

I was going to try 265/35/18 and 295/30/18 Nankang AR-1s on some 513Ms once i wear out my PSSs (2-3 more track days im guessing).

Do you get those tires in the usa?

@5.M0NSTER have you seen these camber plates? might be OK for the street but have not looked up reviews
