So as I've been tracking the car more and more, started to feel the that the stock seats were no longer cutting it. To try and stay in place I was having to brace myself with my knees, and this in turn made it difficult to be precise with my brake and throttle inputs. Only issue here is that the majority of the aftermarket seats that fit the S2000, don't fit me. I am what you could call "fluffy" (6'0" 280lbs 42" waist) and as you can imagine my options were extremely limited. I had tried several different seats: Recaro PP (barely fit, but harness holes are too low), Sparco EvoII US (fit decent, but requires extensive work to fit the car), and looked at ordering the Marrad ST3 (which are copies of the Recaro Pole Position ABE which are a little wider than the regular PP and have larger harness holes, but have no FIA or SFI certification). During my last track day with Track Night in America, one of the local S2000 guys had recently installed a Corbeau Forza Sport and I asked if I could sit in it. The seat fit me good (about the same as the Sparco EvoII US) is FIA certified, had proper harness holes, cost less than half of the Sparco and Recaro options, and best of all fit the S2000 with no modifications needed! So I decided to order the seat along with the Corbeau seat brackets with double locking sliders. Ordered the seats from THMotorsports
who had the lowest price and also offered free shipping. The seat arrived one week after I ordered it, shipped directly from Corbeau
The seat was packaged very well, it included the seat brackets in the box which are very well made with thick steel and predrilled for the S2000.
The bracket install was very straightforward, the Forza Sport comes with options to either do a side mount or bottom mount, the Corbeau seat brackets use the bottom mounting option. To install just remove the 4 hex mounting bolts on the bottom of the seat, align with the holes in the slider and install.
The brackets also include a place to mount the OEM seatbelt, which many aftermarket brackets do not
Bracket install took maybe 10 minutes total, and the seat was ready to go in the car
Here's a closeup of the seat and materials, it has good padding and the cloth like material seems to be good quality, I would say equal to what you get on a Sparco seat.
Side by side with the stock seat
The seat install itself was very simple, I've read horror stories of installing aftermarket seats and how difficult it is, but with the Corbeau brackets, everything lined up perfectly out of the box, I pushed the seat slider all the way back and installed the front two bolts first but left them loose. Then pushed the seat all the way forward and using a long 3/8 extension easily bolted the back two bolts. Total install time, including removal of the stock seat and moving over the OEM seatbelt buckle was 45 minutes. Here are some pics of the seat installed:
Before the install I took some pictures and measurements of myself in the seat with my helmet, just give others some idea of how low the seat fits. With both seats pused all the way back, the OEM seat was 40" from the floor of the car to the top of my head, the Corbeau seat was just under 39". So with this seat you also gain a little over an inch of headroom. Top is the Corbeau seat, bottom is the stock seat.
Since I am happy with the seat and the ease of installation, I went ahead and ordered another for the passenger side as well. Had the wife try it out, and even though she is much smaller than me, she felt comfortable in the seat and said it felt much more supportive than the stock seat. Hopefully this helps some others in a similar situations, if anyone has any questions about the seat or the install, let me know!
