I'm running Recaro Specialist M's in my 70 (a version of the LX I believe). The regular Specialist/LX have taller side bolsters, but to me the M is much more comfortable on longer drives. Ordered the least expensive version (cloth) and had them upholstered to mimic factory pattern. The seat brackets/sliders are from Wedge
