I LOVE THESE ... must have cost a pretty penny?

and they're a bit heavier than the factory cloth seats to boot .... every aftermarket reclining seat is in fact, you won't get anything lighter until using a fixed back seat and even that can be heavier too depending on the seat and mount setup

Cloth seats are 38lbs, right?

The corbau A4 reclining seat is 25lbs, the brackets wouldnt be 13lbs, would they?

Even so, the weight savings just isnt enough for me to justify the cost and the loss of side air bags and who knows what happens to the steering wheel air bag without the seat sensors in place.

If I get seats it would be a fixed seat like the Corbau FX1 pro which comes in at 16lbs.

Weight is not really a big issue for me, DD comfort would be a big seller but I actually just like the way those ones look heh.

Which is exactly what I did.
I have also figured out how to handle ALL of the electronics so that the SRS and seatbelt system remain 100% functional, despite the removal of the seat airbag.

This removed a total of 65 pounds from the car and vastly improved the driving position in every way.

Very cool.

I dont have leather heated seats, so I wont be able to remove 65lbs with seats alone, but the improved seat support would be nice.

If I decide to go for it I will need to talk to you about the electronics.

The factory cloth manual seats with factory sliders & mounts are only 38lbs each (76 lbs total)

I seem to recall that the lightest Bride reclining seat with the low mount & slider is about 50 lbs each or so, plus this is a racing seat thread not a street seat thread ....

a simple resistor for the SRS seat air bags plus there is a position switch on the driver side that will need to be electronically duplicated or cut off and reused from the factory seat

the front air bags should still work regardless unless Mazda hires idiots who understand nothing about safety systems since the front and side air bags work on their own separate triggering sensors mounted to detect the position/direction of the impact. It wouldn't be much of a saftey system if one defective or failed component shuts it down completely. the same way it wouldn't be much of a safety system if it didn't notify you of any issues. The SRS light is no different than the CEL. It doesn't mean go vs no-go.

The OE leather driver's seat is 75 lbs. That is where my weight savings begins.


That is part of it, though I have a work-around for the seat position sensor. You also need to hook up the OE belt latch or the rear door latch won't lock, which reduces structural rigidity.

Unfortunately, like the ABS, this isn't true.

If the SRS sets a bag missing code or a code for the position sensor or latch, the SRS is completely disabled.
This is actually for safety since the airbags can kill the driver or passenger if the deploy when the other standard safety equipment isn't in place.
An airbag to he face without a seat belt will kill the driver.

Could you explain this a bit better please? My electronic skills aren't too advanced but would like to put the OE belt latch back in and set the trigger correctly.

Are you sure about it? As said i don't have the belt latch but the door latches do lock!

Thanks Jeff!

So the Corbau FX1 Pro (32lbs for 2) plus Side mounts (53lbs for 2) weigh 85lbs, which still weigh more then my factory cloth manuel seats (76lbs)?

Are the mounts really that heavy or do the seats weigh more then 16lbs each?

Corbau claims the sliding bases with bases (1/8" flat steel w/double locking sliders) weigh about 12 pounds. even if we round up the 16lb seats to 20lbs and the 12lb bases up to 15lbs that is only 35 per side. Only 3lbs, 6lbs total less then the factory but with much improved river support and comfort on the track.

Mr. Pockets

Is that a custom bracket? Did you retain the OEM seat belt?

Thanks.

MazdaManiac

Yes and yes.

Mr. Pockets

Thanks. That doesn't bode well for me - I have no ability to fabricate.

Anyone have any experience with the Cobra Sebring Pro GT? I know the Evo2 fits without modding the trans tunnel and this is pretty similar in size but has about an 1.5 inches of increased width at the base.
My car is scheduled for full cage install in June.

Here is the wiring.

You must retain the factory seatbelt buckle from the stock seat. If you are using a harness instead of the OE belt, you must retain the assembly with the buckle inserted into the latch or construct a similar circuit since it is a pair of proximity sensors, not a pair of hard switches.
Without these engaged, not only will the SAS system return a failure, but the mechanical latches that constitute the "B" pillar will not latch and the structural rigidity of the car will be compromised.

^ does this bypass the passenger weight sensor also for 06+?

Thanks Jeff, that's a weird connection anyway. Door latches and seatbelt buckles?

Thanks for sharing that, appreciate it. I understand you keeping info close to your chest most often than not but this is just an issue of safety, thanks,

I went from the behemoth leather seats though, then I swapped for black cloth interior all around to match the seat

Bullshit. I give everything away all the time.
Half the time, no one understands it and the other half they want me to spoon-feed them in single-syllable words.

This forum wouldn't have any real useful information if I wasn't throwing the baby out with the bath water on a regular basis.

Name ONE SINGLE OTHER FORUM MEMBER that has contributed as much factual, practical, useful and, most importantly, accurate information here.

You can belligerently declare what an ******* I am or how full of myself I might be, but you cannot truthfully answer that question with a name.

And I am not talking about parroting what I have said in some other words or reposting things that are printed in Mazda literature somewhere or regurgitating internet "facts".
This is real, bespoke information.

No. This is the driver's side. I'm not interested in defeating the safety equipment. I want to make the equipment work as properly as it can when the driver's seat has been removed in favor of a racing seat. That is all.

Yeah - the safety system doesn't want the rear doors to go non-functional until it is certain the front occupants are belted in.

bse50

I understand now, the funny thing is that I could swear mine used to lock the couple of days I had the buckle off. There's a 0.5% possibility that this is another little "safety" difference between eudm and usdm cars, like the "neutral" switch.
I will try again just because, since i have to do some work there in the next few days.

Another questions is: What's the "reference" point for the driver's airbag when there's no seat rail? Farther or closer seat position? I'd say Farther but i'm not sure. Not a big issue at the track with the airbags switched off, it may not be a fun experience on the streets though!

Don't know if this qualifies as a racing seat, but managed to adapt the seat from an Elise for my RX8:

But, more importantly, folks around here can stop diminishing the impact of my efforts while simultaneously using the information I provide.

It is mildly amusing to me to watch others take credit and thanks for the things that I've accomplished. But only mildly.

With it hooked up this way, it will believe the seat is all the way back, so the bag expansion rate will be at maximum.
Caveat emptor.
