Does replacing the steering with a non airbag unit and the seat with something like a Recaro PP cause fault codes? Are they able to be tuned/deactivated? I am curious what folks racing these cars are doing.
 
For hpde?
 
Replacing the seat in any modern car is going to cause at minimum an airbag code. The typical route is to find the appropriate resistor. This car is the typical ohm used for japanese cars, it is easy enough to put the resistor in and tape down.

The seat belt receiver on this car has a plug that feeds into the smaller of the two seat harnesses. That also has to be dealt with. Just unplugging it will fully christmas tree the dash, it also seems like jumping out its pins will also Christmas tree. I have not checked the resistance yet.

Some vehicles have a position sensor that is usually easy enough to move over, the driver side of this car does not have one.

A passenger seat will have a weight sensor, you'd be best copying whatever was done on 10th gen civics is my guess on that.

No company makes seat rails, you will need to come up with your own base. Mine was made of flat iron, have done it multiple times in the past on vehicles due to my vertical challenges and nearly all presold bases for other vehicles being elevated from the floor leaving some extra seat lowering unrealized. The holes if i remember right were about 22.5" apart front to back, located in line with eachother side to side, and there was a slight bend at the front of the rail, very simple. The outboard seatbelt attachment is on the seat itself so you will need to accommodate for that as well.

For most people there is absolutely no real benefit in changing the seat for "racing". You have no method to mount harnesses. In terms of strictly safety, safety items work together as a system. You will not improve on what the oem designed without significant compromises otherwise.

I recently swapped out my driver seat for a bit more headroom, it is a downgrade in all regards other than headroom or if you actually think dropping 30 lbs makes a difference in a 4k lb car (it doesn't). It is not safer, it is not more comfortable, it does not make the car faster. I just like not having my head touch the ceiling or having a bent neck with a helmet (past neck injury from flipping a sxs doesn't help), this car has more headroom than most, but it still was a little lacking.


Tldr unless you have a specific need, don't. The oem seats are pretty damn good.
