Bernooo's E92 M3 Clubsport Build

[//steve\\]

Great update on all fronts! Awesome driving and lap time too. I love to see people giving the car all it has with no aero before just jumping to wings on wings.

How do you think the 275s would have done if they had been on 10.5" vs 10" wheels? 10.5 seems like a good size because you can kind of go either way on the tire size with 275 or 295. I absolutely love the Flkse too and it would be great to see them made wider. What is the offset on them now?

Congrats on the baby girl.

Thanks Steve! Yeah, you know... Coming out of a car that had an abundance of power and aero, I really want to take my time to extract all I can from the car in its different stages and see if 3 years of taming that car on track has had an impact on my skill level -- I think it has, and it's fun finding time without making drastic changes.

My thought here is that if I can dial the car in without aero, on street tires, drive it 10/10th's and quickly, I'll have a lot of consistency and data to work with when I decide to add aero or power later on.

Not sure how the 275's would have performed on a 10.5" wheel. Maybe the sidewall would feel a little stiffer if it had some stretch, but I really can't say. The Fikse's aren't the perfect spec to widen, unfortunately, but I'm going to reach out to Fikse to see what's possible. Their current spec is 18x10 +19 with 3" lips. They are custom made Profil 10's, made as light as possible -- 21 lbs each for a 3pc wheel is pretty impressive. Currently, with 275's, I run a 10mm spacer out back purely for looks, and don't have much more room to spare to the fender. I haven't looked inboard yet, but I think we've got plenty of room.

Up front is a different story... Inner clearance is tight. I can fit the wheels with no spacer, but I run a 5mm up there for piece of mind and for looks. I've got more room to spare outside, still, and haven't tried a 10mm up there, but I will soon. What I'm getting at, is: Maybe I can run 3.5" lips to get these to 18x10.5. 1/2" = 12.7mm, so I'll have to stack some spacers and take a look.

Otherwise, given the supposed inboard space out back, maybe i can just widen the rears and try a staggered setup to give the rear some more grip. Curious to try the new Falken 660's. I have a buddy that had great results running them in 275 front, 315 rear...

More soon! Waiting on my rear cage, and then it's time to install that, a passengers Sparco Evo, harnesses on both sides, CAE shifter, AKG trans mounts, full Macht Schnell solid rear subframe bushings, all the SPL rear arms, and a fresh front/rear BBK from StopTech. Can't wait to see the nickel plated Trophy!

Can't wait to see more progress! Loving it so far berns

Wanted to see what my best SUR4G lap looked like from the KW day at Buttonwillow last month. This was the morning session before I threw on the used A052's and ran the 55.1. Comparatively, the Nexen's definitely have grip, but the sidewalls feel a bit soft and mushy. Turn-in is less immediate, and weight transfer is felt way more in transitions. With a little bit more patience, though, you can still be fast on these tires, and for the price, they're a bargain.
If all out speed is what you're after, obviously there are stronger contenders in the 200tw segment. I still have yet to try the AR1's, upcoming CR1's and the Falken 660's, but the Nexen's are a great low-risk lapping tire and they last forever.

Here'e the lap:

Still waiting on the cage to show up from Pinnacle Motorsport -- really looking forward to installing that along with the shifter, pass seat and harnesses soon. Not actually sure when I'll go back to the track with the newborn, but I'm feeling optimistic I can sneak out for a day in January!

I love this thread, I'm hooked!

[SoCalRPM]

Fun build to follow. Great write up

[Kelse92]

berns you mention the long life of the Next and while I'm not too familiar with the Next I am with RS4's. How would you compare those two tires? They seem pretty comparable on wear rate and speed, or would the RS4 be a hair slower?

[fsmtnbiker]

On track I think the SUR4G is faster than the RS4. I didn't love how they felt but the times were right there with (or faster) than RE71s when I ran them back to back.

^ I've always heard they are nearly the same tire and it would take a fairly advanced level driver to find the differences.

I haven't driven on RS4's, but for sure, the SUR4G's are quicker and have garnered a much stronger reputation since their release.

The Nexen's hold up, are quick, and they're affordable. Easy to drive on the limit and past it, but do take some driver adjustments to get acquainted (re: soft-ish sidewall).

The only tires I'd consider in the "street" tire segment are these:

Nexen SUR4G
Yoko A052
Falken RT660
Nankang CR1
Bridgestone RE71R

[Kelse92]

I've driven on all the others except the new Nankang so interesting you put the Nexens in line with the others. Of course not the fastest tire, but for a good value I was thinking of grabbing a set of them or 660's in the big sizes now that those are out. Nice to have a good 200tw set on standby for lapping or lead-follow instructing. Thanks for the feedback!

Not sure why, but a lot of people discounted the Nexen's before even trying them. I've always been an advocate, and have always set quick times on them. They are a solid tire.

I just ordered a set of RT660's in 285/30/18 and I'm going to stick with Falken for the 2021 season. I'll try them 285 square on 10.5" wheels and maybe 275/315 staggered on 18x10/18x11. I've got data from the SUR4G's and A052's, so it'll be interesting to see how they compare.

I'll have my first impressions of them after my next track day on 1/29.

You recommend 285/30/18 over 275/35/18 on a 10.5?

Depends on the tire, I guess, but generally, a 275 is a bit narrow for a 10.5" wheel. I also really like how the car feels with a 30 sidewall, as much as I don't love how it looks. Definitely has a gearing improvement.

It's a square setup with 18x10.5 +25 and 295/30 all around. 3mm spacer up front for peace of mind and 5mm out back for style points. Fitment is killer and I'm in love with this setup!

berns Any rubbing with this setup? I want to run 275/35/18 on these wheels with Falken 660's

I have the RT660's in 275/35/18 square on apex 18x10.5s with et22 so very similar to the Titans. Its very tight up front, I rubbed slightly on the fender liner but it clearanced itself pretty quickly. The 660s run a bit wide for their size.

Yep, I saw your thread. Very helpful. Any spacers?

The reviews on the TireRack site are complaining of splicing with the new RT660. Assuming you didn't have that issue.

I've heard this as well. My 285/30-18 RT660s have had no tread splice issues at all.

[vma1788]

I now have 3 events (4-6 sessions each day) on my RT660s and they look like they will do 2-3 more before they have no tread left. Now, to see how they will do as they wear. It would awesome if they are like NT01 and have consistent grip down to the cords but we will see.

Not the same weight car or sizes but the 17” spec size 660 we had on the BRZ wore very evenly.

No spacers for me. I haven't gotten on track yet so I cannot comment on tread splicing.
