My setup is basically:

Regular:
Engine: Efficient
Chassis: Comfort
Steering: Comfort
Brake: Comfort
DSC On

M1:
Engine: Sport Plus
Chassis: Sport
Steering: Sport
Brake: Comfort
DSC On

M2:
Engine: Efficient
Chassis: Sport Plus
Steering: Sport
Brake: Comfort
DSC Off, M Traction: 6

I assume that because my engine is on efficient, it was executing the M1 path when I turned on M2, and the M1 path when I turned on M1?

Engine: efficient is relatively popular for track use, since the car is super torquey and this makes the throttle much easier to modulate. I don't mind the workaround for now, but would be awesome if there's a way to maybe incorporate DSC settings or something in the decision making. Love the cando on the track, much nicer to jump in and press M2 and have the track mode up, instead of fiddling with menus.

MCS Installed



As well as some SPL goodies (front sway bar links, front tie rods, rear toe links)







Big shoutout to BSP Motorsports for helping get this all together and setting the car up.

They also found some nice ways to mount the reservoirs:




Also added some more front camber, resulting alignment numbers:



Initial impressions from driving home on bumpy country roads is that these dampers are insane in handling high speed bumps. The shop left them with all settings midway, and it's kind of crazy how well it rides on the street.

I have a lot of work to do to figure these dampers out. But just on the street, the car feels a lot sharper with the higher spring rates. Hoping this will translate to more stability in transitions!

Coding faults out

I got my seat and EDC errors coded out today by kubax86 .

I wasn't sure about what to expect, but this was a super easy and awesome process, 100% would recommend.

All I did was purchase the EDC code out and Race Seats coding from https://bimmer-remote.com/, and ordered an ENET OBD2 cable from amazon .

We coordinated on a time, and then I just needed to plug in the cable to a windows laptop with teamviewer on, and chilled back for a few mins.

After the first pass, the EDC and seat errors went away, but when I put it into reverse, I get the parking assist fault.

It was the same situation as https://g80.bimmerpost.com/forums/sh....php?t=2162969, where the auto parking feature requires the seatbelt.



I sent the error to kubax86 and after another min or two, they were able to code this out.



Car is now fault-free! Very satisfied with the experience.

I like that rear reservoir mounting!. What psi did you charge the reservoirs to?

I don't think they touched the reservoir pressure at all, so they would be at whatever the previous owner had them at, I think. (assuming that fronts don't require de-pressurizing to remove the QDs?). I assume they are at MCS recommended pressures, but not sure.

Car felt pretty good on track on saturday, didn't feel like I needed more spring rate anywhere so I'm just going to go schrodinger's pressure for these for now and will tweak once I figure out what I'm missing

If you can connect and disconnect the QD's then you likely have zero pressure in there. I will be at Cresson this Saturday and I can bring my nitrogen bottle if you want to charge them up.

ECR Shakedown

I took the car out to ECR over the weekend, unknowingly on an instructional day so it was super busy, as the member sessions had all of the instructors in it, as well as racecars (SPB, GR Cup, Formula Mazda) prepping for races, and some members who brought guests.



Got only a handful of clean laps in 2:08s.

I was pretty distracted the whole day and forgot capture any video. Even autopiloted out of the house in crocs.



The car feels way more planted and grippier, and the most noticeable change is how the weight reacts to inputs (previously, any bit of brakes sent the car into oversteer mode, any steering shifts throws the weight left or right and easily induces oversteer), and now it reacts a lot slower.

As a result, I think I'm very under the limit and experiencing a lot of understeer from not getting enough weight transfer done. Tires are on day 7 and feeling less grippy, but even then I was driving under the limit on these most of the day, so lot of driver mod needed to adjust to the new setup. I think dampening is generally in a good spot, and I can get the car to do what I want to do through better inputs, so going to get consistent with that before starting to change things up.

Oh dang I completely didn't realize apex was doing an event at MSR this weekend. Been meaning to run MSRC in this car. Oh well.

I'll follow up with BSP, I assume they've been through enough of these MCS remote systems at this point lol

Hi, sorry it took a while to get back. I'm not getting the notifications for some reason!

With your current setup, you are able to distinguish between M1 and M2. Under settings, choose Chassis Sport for M1, that should do the trick.

MCS & CRS V2 shakedown - New ECR PB of 2:06.78

New tires and got a chance to properly drive the new setup today at ECR.

Cheating a little bit on my PB time since I messed up the last corner exit on the quicker lap, so I moved the start line back, so unofficial cheater PB lol.

Also thanks Biglife for hanging out today and giving some feedback on my driving and on the car.

The biggest feedback item is that my brakes aren't stopping consistently, which hasn't occurred to me but looking back at my driving and data, it definitely seems to be the case and I've adjusted my driving around it, but I'm not as confident on the brakes as I can be.

I'm wondering if this is self inflicted by throwing the Endless CCRG pads on the stock rotors without resurfacing lol, I had hoped some street driving and the abrasion would clean off any stock deposit, but maybe these aren't aggro enough.
Or maybe these pads aren't amazing at dealing with the heat consistently, since they are more of a street/track hybrid pad.
Either way, will probably get a new set of pads/rotors next. I have recommendations for CSG and for Cobalt.

Nice video!

I have a pair of lightly used Girodiscs that are bedded with Carbotech/G-loc compound if you are interested. I also have a pair of carbotech pads that had ~2 track days left in them.
I only used the Girodiscs for one track day and found them to be more consistent than the stock rotors. I am assuming because of better heat dissipation and grooves versus drilled holes.

[LeggoRacing]

Nice lap and getting better. I'd shy away from cobalt. They chunk and taper pretty badly on heavy cars... Step up to the endless me20. I'm still in love with this pad as they survive full sessions at cota without a whimper. Get the speed engineering brake ducts if you don't have them already

[jacktli_g87]

ZPD might be interested, I'll message you I have a set of XP10 in my garage actually that I wasn't sure if I was going to use, but this might work out.

LeggoRacing yeah I do want to try the me20. kind of a pain to get because of the lead time lol

I had Cobalt and had high hopes for them because the pad is slightly thicker than others. However, they did taper pretty severely, limiting their life. So far, my favorites are the Carbotech XP20 (front) and XP12 (rear), although I never tried CSG or Endless.

Just order them way ahead of time so they're just sitting there waiting. You can actually get them more than half off too order direct from source in Japan ...

I'll probably try something out for the next set just because

Thanks for great content!

I have a question about seats
Do you have to do some coding after throwing out OEM seats? I would also like to throw out passenger and rear seats for upcoming track days but does the car go into limp mode or just show some annoying errors?

My season first time attack event in the beginning of the May (square 305 AR1 on 19/11 wheels, modded exhaust and BM3, suspension secrets camber plates, endless ME20).

if you are not seeing a lot of heat checking on the rotors, they are fine. changing them is not going to make the braking better. you need pads that are track specific. I highly recommend something in the Performance Friction line. PF08 compound is perfect for track days. last longer and have a great feel. PF11 wont last as long as 08's, but has more initial bite. I have been using various PF pads in my race cars for 20years.

for longevity of rotors...the metal used matters. cheap rotors don't last as metal imperfections cause them to heat check then crack. that kills them long before they wear out. Girodisk brand are superior for longevity. when i switched from a different brand to Girodisk on my current race car I was shocked how long they lasted. they wore out before they were heat damaged.

They just throw annoying codes, but no limp mode or anything.
The error messages happen to block part of the info display on the main dash, so I got them coded out by bimmer-remote (highly recommend! See post #47)

Thanks for the insight! Yeah Girodisc is definitely next.

I find that picking brake pad brands is kind of like being sorted into one of the houses like in Harry Potter lol.

I have heard great things about pfc.

jealous of you getting to use your M2 as intended!!

Mine is still stuck at the VDC waiting for the Stop Sale to be rescinded. over three weeks sitting there so far.

Ah bummer, I've got a friend that's in the same situation, who found out after he arrived at the dealership expecting to take delivery. Hope it gets sorted soon!

[Biglife]

Joining the party late here, but it was awesome to link up with jacktli_g87. He'll be knocking down 2:05's, when he get's the platform sorted.

Aside from the brakes, the CRS v2s felt pretty terrible. It might’ve been the tire pressures—when I took a few laps after Jack had been pushing it, they were touching 40 PSI. Grip and feedback were seriously lacking. Even in the mid-30s, it still felt off. I didn’t get another chance to try them, but from what I heard, things improved a bit once he dropped the pressures into the mid-20s and kept them under 32.

Anyone else feel underwhelmed by the CRS v2s? Honestly, the Hankook RS4s feel better. Even the Pirellis felt better.
