Sparco Roadster seats

[nsx1164]

Does anyone have Sparco Roadster in their cars.. I would like to try sitting in a seat before i buy em.

Theres a group buy on another car-club forum --

Any feedback on fitments in an NSX ?
- increased headroom
- ability to use 5-point harness
- comfort on long drives
- seating position ?
- mounts ??

IIRC Chris at SoS had a set on sale...

Thanks -- Manuel
