Yep, custom mounts are the way to go. The sparco hardware is notoriously crap, doesnt fit all that well and wont get the seat any lower than stock height. Best bet is to have a race shop (piper) make a seat mount for you, weld a sparco universal slider onto that and shorten and weld the side mounts onto the slider. Then again, do you need sliders on the car? With a MR2 i dont see the need to move the seat much.
