A bit unconventional but worked for my 8 gen civics-using m16 washers and longer seat base fixing bolts, I raised the rear of the seat base using the washers packing under the two rear seat base fixings.
3 or 4 each corner with the longer bolts worked for me. Very much a personal thing, but for me making the seat that bit more comfortable on longer journeys.
