depends on the seat. leather seats with the knobs on the side for the seat sit a bit higher than say a cloth GSR seat which sits higher than a s2000 seat. which sits about the same as a del sol seat. There is some differences in the actual rail too, some of them have a spacer on the rear right corner (where you put bolts in) where its flat instead of angled im not sure if those rails are a tad different in height. but if you want that low seat feeling the s2000 seats make a big difference from an adjustable leather seat and a tad difference between cloth You can really tell the difference too, im not tall but i hit my knee on the steering column when i heel toe with the wheel all the way up sometimes with cloth gsr seats, never with a bucket or a s2k seat.
