Replacing Z4M seats with recaro pole positions
Anyone changed their M seats for racing seats (recaro/cobra). Am considering doing it myself but was wondering what kind of hurdles I'd have to jump through first (airbag issues/base frames fitting/squeaks rattles etc).
What kind of price could I get for my oems?...trying to offset the cost of the upgrade |

Pretty sure Recaro makes bases for the Z4, as well as VAC motorsports http://www.vacmotorsports.com/ .
The airbag light will be on, I don't know if you can get the dealership to turn it off or not. And if you were in the US, I'd gladly take the M seats off your hands. Good condition, common colored leather would probably go in the $500-1000/pair range. |

I'm in the process of putting in some Cobra Suzuka's. I'm building my own base plates instead of the VAC ones so I can make them perfect for what I need ( 3/4" thick aluminum plate like the VAC's, but only with the size / holes I need to keep weight down). I made some mock ones out of Oak first to make sure I got the perfect size / fit / seat placement.
It's a pretty labor intensive job so far, but I'm really looking forward to getting it all together. Hopefully I'll have the plates finished this week so I can get them anodized and put in. As far as the Airbag SRS light. From what I've learned so far the only way past that is to either get a resistor wired in somehow ( I've heard this doesn't work tho ) or to get a passenger seat occupancy mat out of a stock Z4 M Sport seat and place it under the passenger seat padding / plug it in. That said, I asked the dealer about getting one, and here in the US they only sell it with the base of the seat / leather & foam included for $1500.00.... Yikes. They said I could try to get it separately in EU, but I haven't asked anyone about that yet. All in all tho, I'm really excited to see the total weight dropped in the end... I'm optimistic it's going to be between 75-100 lbs after the addition of the mounting plates / harness bar and seat belts. I've heard the stock seats weigh 70 lbs a side, and they do feel super heavy, but I haven't weighed them yet to confirm. As far as selling your seats.. I'd keep 'em, because you never know what you'll do in the future, and the OEM price of them in the US is $4k each if you need to replace them. Hope this helps... |

Going from a stock Z4M seat to a fixed cabon or FRP backed bucket seat will save much more than 10lbs, in most cases you'd gain that alone in the mounting brackets. I'll likely tackle this in the future in an effort to save some weight as well, but can tell you that in our 996tt which also "Felt" light during removal, we where able to save a net savings of over 70lbs by switching to Status Ring seats with appropriate hardware, I'm willing to bet the Z4M will present a similar savings. Anything lighter than factory is an improvement in my books.

It's gonna be ALOT more than 10lbs a seat... the stockers supposedly weigh 70 lbs EACH, these Cobra's weigh 20 each. Like I said, I'll weigh it all when I get the brackets done. We have a digital shipping scale here at work so it'll be accurate.
I weighed the stock battery and it was 49lbs !!!! I just got a Braille BB2317 battery that weighs 17lbs ( no not the poser carbon one either... hahaha ) to replace it that they said would be OK for DD use... guess we'll see. I just got the kevlar Suzuka S with the Rock fabric... Got them used, but they look BRAND NEW, and I got them for a steal ! Looking at recovering them in Alcantara and having some White top stitching done. One thing at a time tho.... If I got them new, I def woulda gone the Pro route like you're saying. These seats are so comfortable... can't wait to get it all in !!! |

The main benefit is added side support for aggressive track and canyon driving, and the ability to run harnesses. Comfort will be less than stock unless you have custom cushions made. Weight savings over stock M power adjustable and heated seats will be huge but not terribly significant over full-manual non-power M seats.

Sparco Torinos aren't race seats, they're more like sporty OEM seats. The Pole Position is a pretty hardcore race shell with relatively little padding. Not necessarily uncomfortable, but not as nice as stock seats in that department. I ran Recaro SPGs in my last car, which are a more aggressive, narrower version of the Pole Position and I was ok with spending all day in them. My passengers though, had a very different opinion...

I almost put a set of these in the car.
Just under 6lbs without hardware, surprisingly they're not as uncomfortable as they look. I'm 5'11 /160 and they held me in the seat quite well, real ergonomic. |

Help again! Im tearing my hair out trying to figure how to bolt the seats (pole positions for example) to my car. Recaro dont make a subframe for the Z4. Most tuning workshops have no idea about the Z4...only the more mainstream models.
Grrr... |

http://www.europeanautosource.com/in...78e1926a25eb50 So you need the mounting plates, AND the recaro side plates... The EAS ones look nice because they also have that bolt on plate for your lap harness. So you bolt in the plates to your car, then the seat side plates down to the floor plate... You need to use 12.9 Socket Head Cap screw Allen Head Bolts, and make sure you get hardened steel washers for them all as well. |
