I have Sparco Milano's in my 79. Bit on the pricey side, but still I think easily worth the money, best seats I've ever tried. Tight fit, but still works. :cheers:
Seating and interior ergonomics are so personal, it's really hard to say what really works for YOU vs ME, is impossible.....for instance, I look at the seat above and think my '87 vette, one of the things I hated about it was the side bolsters on the seat were way tooooooo snug on my hips...they hurt from bone compression....I suffer arthritis anyway, so don't need any bone massage....
it APPEARS like a lousey fit for ME.....which is why I cut the interior all up in my '72 vert here....lower/forward the gas and brake pedals, pushed the floorboard forward and and lower below the steering wheel mount flange, and eliminated the dimmer bulge for the dimmer is on my TT wheel now....and too boot took out the rear mount flanges to lower the seat back by 1.5 inches, and too out all the padding/carpeting under the front mounts for same reason, picking up another 1/2 inch....this all acted to flatten out my knees from under the freeking wheel, and make my seating much more comfy.....
I need HEADROOM in a car, even more than knee room....which for a long time driver/hobby car like this vette has to be adequate for ME....
so I doubt it's worth the effort fo try another seat at this point....course I don't drive competitive either, ....
