I bought Recaro LS-C seats for my E9. As the car is on rust repairs and stripped down, I have possibility to create the perfect height for the seats, as I'm doing new rails too. Of course I did not measure the original seat height before removing seats etc. Now the question is, what would be good height for the seat. I'm 183cm/6ft tall. Upholsterer who's doing the seat and rails, asked the height from floor to the front base of the seat. Picture attached to show the spot. Could someone recommend what height would be good? Thanks!
