Race seats for C5 convert

[BossV8]

Hello,

First of all, please accept my apologies for writing in English. My German language level is very basic.

I am a French Corvette C5 owner. I own a 2000 convert with manual gear box which makes 393 hp, and has pfadt Motorsport suspension and performance friction brakes. I use my C5 on the track.

I would like to upgrade my seats and I was wondering if you guys in Germany have found direct fit race seats solutions?
Here in France, we find lots of race seats, but no specific adaptor for the C5.

Thanks for your help.
