Very pleased with the tires.

Wow! That is a good price. I will have to check that out. Thanks man!

Do your mirrors fold in automatically when you park or lock? Mine fold in when the fob lock button is depressed 1.5 seconds ...would love it to be automatic.

I'm sure both tires are great for the street but I think PS4S will be hands down better. It's a matter if you think its $400 better.


The mirrors close when I either press the lock for 1.5seconds or hold my hand over the comfort access lock button for the same duration. If you press the interior button, when you unlock the car it won't unfold automatically which is a bummer lol.

I bought my 275 PS4S from DT last week for $247/tire. It looks like the extreme contacts are $203 in that size, so the price difference is more like 44x4 or $176 for a set of four. DT had a $70 rebate on Michelin tires last week too...

Sounds like that is what I need to do. Get them at $247/tire and $70 rebate. Time to call America's Tire (our DT here)

I think DT has a $100 rebate going for President's Day right now for a set of four tires.

Great clean build! Not sure how I missed this, but awesome pick up. Can't wait to see w/ the new wheels mounted up!

Derek,

Nice ride and great blog. I have the same E90 M3 color combination, Alpine White/Black interior and with the same 219M wheels as you. Have you picked up the 18/15 mm spacers already? Any chance you can throw them on your car. Would love to see how that looks with stock wheels.

Thanks man! I loved your build at PTech.

I did pick up spacers but I did not plan to install them on the stock wheels due to the extra work involved. :P If I'm taking off the stock 219Ms they are coming off!!


Specs:
15mm Front
18mm Rear

Final Specs
18x10 +25 front
18x10 +22 Rear
275/35/18 PS4S

On another note, I just received my BBS Caps from IND today!




Last bits to do:

• Unplugg the TPMS module and code in FTM monitor flats indirectly.
• Buy Tires and get them mounted
• Install the wheel studs/spacers

# BBS GT4 RE Installation Day
Today is GT4 install day! After finally caving and buying tires on Tuesday, it's time to install them!

## Goal for Today

• Install Apex 90mm wheel studs
• Install Apex 15/18mm Spacers
• Install BBS GT4 REs w/ 275/35/18 Michelin PS4S
• Remove TPMS (Tire Pressure Sensor) or referred as RDC
• Code in FTM (Flat Tire Monitor) or referred as RPA

## Coding
The BBS GT4s use 8mm valve-stems instead of the factory BMW 11mm valve-stems. For those who wish to retain TPMS sensors, there is an option here: https://**************/BBS_wheel_TPM...4_p/bbsrdv.htm I personally didn't want to spend the extra money for this and second set of sensors. I figured the economical decision is to ditch the whole wheel sensors altogether and revert back to the Euro E9x/Pre-LCI E9x FTM system.

FTM = It uses the speed sensors in each wheel and compares rotational speeds to check if there is a differential between wheels. This will determine if there is a flat if there is a large deviation. The con is if there is a decrease in tire pressure across ALL tires due to not checking, it will not detect that. (ie. All tires drop to 29psi instead of set 33psi)

TPMS = This uses sensors in the wheels and connects to a main RDC unit in the passenger rear wheel well (at least for LCI E90 2010+). This system is more accurate but can get costly with extra sensors when multiple sets of rims or in my case, racing rims that were not designed for TPMS.

During my research, I found a thread that describing exactly what I wanted to do! http://e84.xbimmers.com/forums/showthread.php?t=1145078 Thanks improvius for documenting this awesome finding!

The first step is to take off the rear right wheel and undo the inner fender liner. After that, I unplugged the RDC module which is in the lowest rearmost area of the fender liner. Next up, coding!

### NCSExpert changes

• Remove $2VB vehicle order
• Add $265 vehicle order
• FA Write to the CAS module
• Either code defaults to CAS, KOMBI, DSC, CIC or add the following code to the corresponding module:

CIC: RPA_CIC
aktiv
CIC: RDC
nicht_aktiv
CIC: RDC_SAFETY
nicht_aktiv
KOMBI: RDC_ALIVE
nicht_aktiv
KOMBI: MMI_ENA_RPA_RDC
aktiv
KOMBI: RDC_VERBAUT
nicht_aktiv
KOMBI: DSC_MIT_RPA_CC
aktiv
KOMBI: RDC_DISP_SWITCH
nicht_aktiv
MK60_M3: RPA
aktiv

CIC module now shows FTM instead of TPMS!


## Installation
A small storm as passed through San Francisco and today had a slight 50% chance of rain mid-day. Luckily the driveway wasn't too bad.




Off comes the 219M wheels! The PSS tires only have about 3k miles on them so they are looking sharp!


My cousin's 328i E90 in the background just happens to be on GT4s too


My brother's Msport 11 E90 335d, Cousin's 08 328i and my 11 E90 M3.


Installed!


After I reset and initialized the FTM, I drove around it now shows active instead of FTM malfunction!


Few more pics:



## Impressions
Final Specs:

• Front: 18x10+25 275/35/18 Michelin PS4S
• Rear: 18x10+22 275/35/18 Michelin PS4S

The rear looks like it has room for a 20mm spacer instead of an 18mm. The front is perfect with the 15mm spacer. For now, I'll leave it as is. I didn't get to drive it more as I had some errands to take care of. Back into the garage, it goes!

Initial impression of the square setup is that the steering is a bit looser but I will check more the next time I drive it. I'm now itching to lower it... YIKES.

Thanks for reading!

How long did you leave the studs in before mounting tires? Just wondering how long it takes the loctite to set?

Initial cure time is about one hour. A full cure is 24hours. I wanted about 2-3 hours (was waiting for tires to be mounted while I installed the studs)

No problem! Apex has an install PDF on their website.

Thanks Mark!

Welcome derbo !!! very similar story here, started my BMW journey w/ a 2003 ZHP (fellow ZHP mafia member as well) and progressed to an e90!!! I love the e46 M3 so much though, that I decided to buy one as well! Don't mean to clutter your build thread w/ pics of my cars but just thought I'd share:

[SFCM3]

interesting read, I am also local in SF and have an e90m3 that replaced an e90 335d M-sport in black sapphire pearl, identical to your brothers!~

any interest in selling the 219s?

[94jedi]

Love the GT4's btw...(actually, love almost anything BBS lol)

Thanks! Hope to meet you sometime at the local track/meets! There is a possibility I may sell the 219Ms. PM me.

GT4 is one of my all-time favorites BBS. I'm lucky enough to find a nice set and it satisfies my need for an "OE" type rim. I really love these rims over the ZCP because they are 18s and cheaper for tires!

[TigerTater]

What made you want to do studs? Look, ease of access and rotating tires? I'm debating on a set...the wheels are smokin btw

I'm running a 15mm/18mm spacer because of the high offsets on the rims. Instead of buying 18mm wheel bolts and 15mm wheel bolts, I opt for 90mm wheel studs all around.

From my research, if I ever decide to go to Ohlins R&T or B16 Damptronics, the front will require an extra 5mm for clearance of the spring perches. That means I will most likely need a 20mm spacer up front (18x10+20). The rear should have room to clear a 25mm spacer (18x10+15 final spec).

Wheelstuds are easier to get wheels on, better compatibility with different spacer sizes. That's why I did it!

Hey Derek!

Awesome car, I'm really excited to see what you bring to the table here. Plus, I especially like your fiance's choice in cars as well. Any girl who picks an M3 is okay in my book

Mary

Edit: Oops, just realized your girl's car is an M2... still qualifies lol
