Still good enough to change them to Recaro, I should be able to save about 100 LBS.

The question becomes is it possible to replace the seats while retaining air bag functionality and without warning lights?

rzm3 · 08-30-2008, 12:46 PM

how about this babe? comfortable and will work with all sensors.

That looks sweet, what's the price on that puppy?

rzm3 · 08-30-2008, 01:01 PM

just searched on eBay: $5k for a pair... much better than expected

Ouch, I don't call that good.

Actually I was very very satisfied with the stock seats. When compared to my E36 vader seats, the E9x seats do an excellent job of holding me in position at track speeds. I didn't miss the euro seat bottom bolsters at all.

synclastica_86 · 08-30-2008, 02:53 PM

I'd go for it!!!!! I wish there were an M3 logo on the seats though.

How much do these weigh? They are still heated and have airbags, and I can't see them being much lighter than stock.

If we were able to specify leather and color to go with existing interior, I'd be all over this for $5k. But I don't think I can give up fox red just for lighter seats with better bolstering. Fox red of that however, and I'm sold.

Forgive me, I've never did that to any of my cars before, but how is the harness attach without a roll cage?

harness bar

synclastica_86 · 08-30-2008, 05:49 PM

Where do you install it? Any pictures? Is it readily removable?

ace996 · 08-30-2008, 09:31 PM

Having installed race seats in other cars, here'smy take...
- a resistor will work for the airbag in the seat and not throw an airbag light.
- the weight sensors can usually be removed from the stock seats and installed in the race seats...they are usually bladders.
- the stock seats usually have a sensor that reads how far forward/back the seat is positioned to determine how hard/fast the airbag deploys. The sensors can usually be removed from the bottom of the seat sliders and connected to te bottom of the raceseats.
- a stock-type male insert usually needs to be bought/made to plug into the stock female receiver to keep beeping/blinking/flashing/annoyances from happening. This may also effect the airbag deployment strength (no seatbelt seen by the car and the airbag comes out like a frigging nuclear bomb!!!)

Losing theside bags is not a real concern for me if I can get a proper seat/harness setup. The real issue will be how to attach the shoulder belts without a harnessbar/roll-bar. Schroth has harnesses that sometimes attach to the rear belts at the seats, in the stock receptacles, or that connect to the shoulder mounts by the C-pillars...the C-pillar mounts, I believe, is the only track-legal way without a bar.

Regarding the 4-mount harnesses.... again, Schroth makes a DOT legal ASM (anti-submarine) harness that is legal whenever a 3-point harness is legal - track or street. It has a special release on the center clip that is red...so paramedics can push it like a stock seatbelt release.

And comfort...my Recaro Speed recliner seat is more comfortable than the stock M3 seat...doubt it?...I'll bet you a harness that you'd find it more comfortable. The Recaro Sport is also pretty comfortable, too, and can be bought in black leather.

Going one step further, the Porsche GT3 seat is a modified Recaro PP and they would look awesome!!!

I like this post but do we know the sensors can be moved for sure? As soon as we know, I would be interested in a set of lightweight seats.

synclastica_86 · 08-31-2008, 04:21 PM

So any pictures of a harness in a car w/o roll cage?

sayemthree · 08-31-2008, 05:08 PM

no one seems concerned about safety - most sactioning bodies reuquire a roll bar when you have harnesses- otherwise a rollover can easily resuilt in a broken neck.

Not worth it whatsoever. What is the stock weight though? I can't read that language.
