As I continue to go down the rabbit hole of weight reduction/track-inspired modifications... bucket seats were next up on the list.

With a budget of $1,000 shipped for a pair of seats and hardware to mount them, I started my search. Ideally, that price would include sliders because other people drive my car and a fixed seat would be inconvenient. I didn’t want fancy, reclining seats because I'm doing this to save weight. I was tempted to go with a pair of cheap NRG seats from eBay, but decided against it. Buying the cheapest possible safety equipment doesn't seem like a good idea.

That's when I stumbled on Corbeau's website and found some attractive, affordable options. I narrowed it down to their FX1 Pro seats for $339 each and E92 (E8X/E9X) brackets with sliders for $119 each. Quality, name brand stuff totaling up to $916, just within my budget!

A few days later and I had a package waiting at home.







Out with the old...





Seat installed on bracket and buckle swapped over...







All done!





I will admit, these seats are pretty comfortable for being a race seat. If I were taking the car on a cross-country road trip, I’d prefer the stock seats… but when will I be taking this car on a cross-country road trip? I’m much happier that my body isn’t flopping around when I’m ripping around the track!

I ordered a pair of 8″ seatbelt extenders so I could snake the belt through the seat. This allows me to buckle up within the seat instead of over the top of the seat.

Surprisingly, the stock seats weigh a massive 59.6 lbs! For comparison, the FX1 Pro and bracket weigh 27.4 lbs. That’s a difference of 32.2 lbs, bringing the total weight loss to 64.4 lbs for the front seats. I’ll take it! I also previously removed the rear seats, which saved about 55 lbs.

Next up; a carbon fiber sunroof delete and carbon fiber door panels!

Oh wait... airbag lights...



I used the ProTool app by BimmerGeeks to get rid of these error codes. Simply connect an Android tablet to your car with a K+DCAN cable and OTG adapter, open up ProTools and go to work!

Under the “Safety” section > MRS – Airbag > Coding > Standard, we must deactivate the following options.

• Seat Mat Sensor (OC3_1)
• Driver Seat Position Sensor (SPSF_1_CD)
• Left-Side Airbag (SIDEBAG_LINKS_1)
• Passenger Seat Position Sensor (SPSBF_1)
• Right-Side Airbag (SIDEBAG_RECHTS_1)

Awesome car man. When I first got my 135 I would always look up How-To videos and yours were always the best ones. I'm actually down in Illinois and will be heading up to Great Lakes Dragway on the 29th for the Midwest Treffen 1/4 Mile Shootout. You should come rip your car down the strip. Here is a link to the event. $35 to register and spectators are free (plus you get a tshirt if you register)

Nice! Thanks for sharing that event, I just checked it out. It's the week after NFZ Midwest, so if my car is still in one piece, I might try to make it out there. I've been wanting to get to GLD as it's a lot better than my local track.
