Bespoke seat brackets for the MKII MR2 to mount your side-mount racing seats as low as possible while also reducing weight! Designed around the Corbeau FX1 Pro seat, but with enough adjustability to fit most side mount racing seats, Wilhelm Raceworks seat brackets weigh less than 6lb per seat and will give you the maximum amount of headroom available. Laser cut from 10ga (.135in / 3.4mm) steel. While not specifically certified, they exceed the FIA thickness specification of 3mm for steel seat mounts. Fits either LH or RH side in LHD or RHD cars.
Made in the USA
$110 per set (mounts one seat)
These brackets are intended for track cars with racing harnesses. They do not include nor are they designed to be used with sliders, and they have no provision for the OEM seat belt attachment. If you want to use your OEM seat belts, you will need to remount the buckle to the mounting stud on the tunnel.
Should fit most side mount racing seats with 11.4" to 11.7" (front-back) mount spacing and 16" to 17.5" mounting width. However, keep in mind that the MR2 cockpit is quite small and wider seats may not fit in the car without modification.

I am offering a $30 refund (per bracket set) for anyone who can help me expand this list by confirming fit with a seat not listed above.
I attempted to build in sufficient adjustability to accommodate a variety of seating positions. Personally, I am 6'1" and wear jeans with a 32" leg, and I use the brackets as configured in the images on this page. There is an additional one adjustment point further back, and two points forward, all on 3/4" spacing. There are also several options for seat height and recline angle. However, please be aware that the rearward most position combined with the lower positions may make it very difficult or impossible to access the rear seat mounting bolts. This will also depend on the exact shape of the seat.
