Seat options for 2011 Jazz VTi-S

Hi there,

I've got an early MY11 Jazz and don't like the seat bases. I'd probably be happy if I could raise the front of the seat base so it supports my legs better and I wouldn't feel like I'm sliding forward when I'm sitting up straight.

Is it possible to simply put a spacer between the seat rail and the floorpan? Would this raise engineering issues?

An alternative might be to put in different seats. Would Civic Type-R seats bolt straight in? Do these have seat base angle adjustment? Would the SRS bag plug straight into the Jazz wiring and work correctly? Would this require an engineering inspection/pass?

Many thanks for any help.
