Bucket seat height

[Tomo 172]

Hi, ive got fitted a pair of sparco pro 2000 seats using the omp subframes and omp side mounts (lower type) however i find that the seats still sit to high for my liking. Im thinking about swapping to either sparco or recaro sidemounts to get them lower? Does anybody know which sit the lowest and what you have used?

Cheers Brett
