Plenty of time left on the table once I learn to stop sucking at braking.

Black car and you were with PCA at Glen this summer? If so, this car hauls. I was amazed how this one black X1 with some "sleeper" plates blew by an E9X (I was instructing in).

Thanks, very helpful info! I was looking for wider Hoosiers but hesitated to use the 295/30 instead of 275/35. What is your experience with the /30 sidewalls?
Any adverse effects in regard to suspension set-up?
Thanks again for posting those details.

Track/Course: Road Atlanta
Lap Time: 1:41.00
Brake Pads: StopTech ST-60/40: Pagid RS29
Tires (Size & Model): BFG R1S 265/35/18 square, Apex Arc-8s
Suspension: GC camber plates -2.6F/-2.0R; stock springs & struts
Other Mods: filter, BPM tune


Rainy weekend at Road Atlanta with Chin Motorsports the week before the Petit LeMans, running in a very fast Red group. Many race teams out testing including Porsche and Lamborghini. 1:41 flat was a couple seconds off best pace but had to slow to allow traffic by (that pair of Lambos were flying!). Virtual best was 1:37.77. A fun day despite the rain. Can't wait to see the race next weekend!

Another shameless plug from a smug N54 driver

Track/Course: Road America
Lap Time: 2:37.65
Brake Pads: Stock setup, PFC 08 pads, solid brake guide bushings
Tires (Size & Model): Hankook R-S3 V2, 265/35R18 & 275/35R18
Suspension: vorshlag camber plates, TC K DA, all M3 control arms, LSD

Pretty happy with the time considering it is my first time at the track. Did suffer some casualty though, my CIC unit crapped out and was constantly rebooting itself at the track (had to tape the screen over so it doesn't distract me). Brand new PFC08 pads are completely worn down to the backing plates, and was smoking at the end of 4th session of the 2nd day...

That's a ridiculously fast time for your car! Good Job. I couldn't even break 2:50 flat with my 335I, and my Modded E92 M3 could only manage a 2:46. How are those PFC 08's on the street? Are they really noisy, and how easy are they on your rotors?

Thanks, it is a horsepower track after all, so the power advantage of the N54 really makes it up at the straights.

They are not too bad when they are new. But after some track time, they are ridiculously loud...even with the windows up. Not so bad on the rotors, but again I don't drive the car that much on the streets. But even with these pads, the front brakes only last about 1.5 day on this track... The FR brakes were smoking at the end of my last session, which I assume it is the dustboots burning up from the lack of thermal mass with the fully worn down pads. My current setup worked great at other slower tracks (GMR, ACC), guess doing hot laps at RA is just asking too much out of them I suppose.

Think I just gonna bite the bullet and get a front BBK for next year. Rear axles are doing totally fine though. I have been running the same PFC08 pads at the rear for this entire season (6 track days) now, and they are only down to 30% after RA.

No one does full 25min sessions at RA. It's just too hard on brakes. It's best to come out after 15mins like I do. BBK will help you, but you will go through pads like crazy at RA.

I max out in the straights at a higher mile per hour than you but your lap times are lower, so I need better pads, but I don't want to have to swap them out on the streets, so my Hawk Street-race are ok for now, but clearly I need better braking. I'm doing ACC/GMR, and RPI next year. If you liked Ginerman, then you should try RPI in Iowa. It was also designed by Alan Wilson, but is a much more fun track than Gingerman.

A bunch of us do Sleeper519 and I are very evenly matched and we played around a fair bit many sessions. As an instructor we can take out a passenger in the A Group too (add more weight). Did a 3 day event last year maximizing every single session (a few back to back also between I group and A/B group with a student) at Road ATL in a 3900lb car with driver zero fade, zero issue. PFC rotors, PF08 or Pagid yellows with Castrol SRF. Think fronts had more than 50% left. Stock system runs like a solid champ all day long. Can get an average of six track days for the fronts. Stock rear rotors with 08s or PYellows.

PS: got rid of the solid pins as it froze all four of my calipers! especially due to street driving (rain/snow etc.).

Agree for most part. Stock system is definitely doable for most tracks. But Road America (not Road Atlanta) is different though, with my car, you have to stop from 150mph twice in just one lap with very little cooling in between them...

Never had problem with my solid pins though, and I drive the car in the winter as well. Ceramic lube help I think.

Are you sure it is your GPS speed? I honestly don't think a stockish M3 can do more than 150mph at the straights, considering my car is running full E85 and pushing around 400-420whp and can barely hit 150.

With my mods, I'd cry if my E92 M3 hit only 150mph on the straights. With Intake, pulleys, test pipes and tune, we have ~400whp at 8,600rpms W/ 7 speed DCT! My speedo reads between 155-160mph at the end of the straights at RA. Now the speedo isn't 100%, but it reads above 150.

I have cobb on my FBO 335I 6AT, and with the 19lb boost race gas map, I was like around 410whp like you, but my E92 M3 can beat it from a roll, no problem.

errr....ever since that thread with the guy whos PFC rotors broke on track, I'm surprised anyone is still recommending those rotors over stock. And as for the stock brake system, if you have decent skills, you won't be able to run them effectively. When I bought my M3 last may, me and another fellow I met at Gingerman, also with an E92 M3, killed the stock brakes. And that's on a 2 mile track with hardly any straight away.

eitherway Cloud9 now has the best time out of any E9X at RA in this thread, with 2.37 beating out Klammer's 2:38. Good Job

I am sure there have been guys who done the course in R compound or slicks

Hi,

Yup that was me! Discovered my car had clogged secondary cats too during that event, I barely made it home before it started almost stalling out. Couldn't accelerate to save my life up the esses

Since then have rebuilt the dampers, added a custom dual core oil cooler with ducting, and added harder front control arm bushings, which is the single best mod I have done to the car (and cheap too). But the best part is besides the brakes, the car looks totally stock from the outside and under the hood.

Next time you see me out at the track please stop by and say hi!

PF is a well known company and supply rotors for a fair bit of race cars including VNL 24 hour series (endurance races...testing durability). So if I read that someone had an issue without knowing it was the product or user error and I cannot discount the entire company's product because of a forum post. I agree stock setup is not efficient but the issue is the rotor(s). Am glad I listened to Bimmerworld folks (they could have sold me on a BBK as I was quite frustrated but asked me to just try the rotors, as a skeptic I did and was amazed). On my 3rd set (on this car) and recommended to plenty others without any issues.

Cheers,

Lutfy

When it ran fine, you flew up the esses pulling yaw angles where I thought this car was done... but nope, this car brakes super deep before the bus stop and fires out like hell!! Absolute joy mate!! I will drop by and say hi and likely ask you for a ride as I was just amazed how f ing quick this (theoretically an SUV) auto is passing well driven Carreras including a few instructors

X1 passing well driven carreras? I am curious what was his lap times at the glen.

We need to have Jon put more info on his X1 or a few videos if he can

From what I can guess, 2:15ish or even quicker (I swear to God I was there on the track and saw all of this) look at his Mid Ohio times above. Absolutely mental!

At the Glen I didn't really get a good lap time, it was my first time at the track and it rained on Sunday I think? Maybe was saturday...anyway I only got a few sessions and the car was not running well.

Here is a 1:44 flat at mid ohio. That GTR that blew me away is insanely fast. Cobb tuned 600whp. I have him in the corners though.

Here is me chasing a GT4 but over driving and making a lot of mistakes. Get passed by a lot of cool hardware including a cup car, a few GTR race cars, etc. There were only a couple of non-stripped dedicated track cars in the group. There was a really cool E92 M3 here running 1:38 on hoosiers. I don't think it is in the video but he was completely gutted, full caged, full carbon aero, BBK front and rear with bimmerworld CF backing plates and custom ducting, data acquisition, James Clay built and tweaked. Extremely awesome car.

These are both in the instructor 1 group with MORPCA.

I have a friend who has a supercharged E36 M3 with aero (he was with me at Watkins running the instructor group, ran a 2:10 flat his first time at the track - you might remember him because his corner headlights fell out on track and they made fun of him in the drivers meeting) drive my car and he was running down race prepped Caymans that were towed there in semi trucks. He is a way better driver than me.

According to GPS data my optimal lap time at Mid Ohio club configuration is a mid 1:41. I think I will need to be much more patient on the throttle and have slower corner entry to even approach that.

I always thought this was a funny picture...at Putnam with 10/10ths

The only guy on this thread who did that in an E92 M3 did a 2:40 Bigjay1976 (sp?)

The guy's running NT01's on all wheel drive. So yes, he should have fast times.
