Hays Knowledgebase Question:

What clutch setup should I use with this combination. Will the aluminum flywheel be ok for the street. (ie. will it handle the heat or will it warp and give me issues.) This car will get driven very hard and will be expected to perform or I will get in big trouble.

Reply from Rep:

Do you need a 10-1/2" clutch or the 11" clutch ? The corvette can run either size and used both. Anything over 475 HP benefits from an Aluminum Flywheel. This flywheel will perform Flawless and you will really notice the lightweight aluminum when you are leaving from a stop. You will be required to give it more gas than normal and get you RPM range up faster. Then at higher speeds you will feel power gains from 3500RPM thru 5500RPM as you are spinning much less Mass. You will really like this Aluminum Flywheel. and it works best with Hays Diaphram style clutch kits
