Is the 1991 Lola Champ Car Full Carbon?

Hello Everyone,



I know that CART allowed Full Carbon cars for the 1991 Season. Do any of you know if the 1991 Lola was a full Carbon Car? If not, when did Lola change their Champ Car/Indy Car Chassis to Full Carbon?



Just curious, so I thought I would ask the pros.



Thanks guys!
