I just ordered a Sparco seat and never followed up on the CC seat. Here is some contact information if you want to invistigate further.
Hello Tom
Thanks for the follow up.
I will attach the mounting dimensions of the Comp coupe seat - talking with
John Archer - he feels sure this will fit into a GTS - do you still have the
door trim?? this could be the only point of contact in a GTS??
You could either contact John Archer or
The guys at Racetech North America - Pete or Ray (714) 894-5010

They have a standard Viper seat there and a large which we will be
displaying at PRI show in Indianapolis in 2 weeks.
We are putting together an order now which will give Racetech NA good stock
for Mid January. If you wanted it earlier we could possibly bring another
seat to PRI.
Please talk with the guys at Racetech NA re ordering a seat and brackets or
get back to me for any more tech advice.
