When I bought my car the fellow told me that it had the Centerforce clutch in it and it has the heavy duty bellhousing. Well I didn't think much about it and could tell that it was harder to push the clutch in more than normal it seems. I eventually got under the car and could tell that it had a aftermarket bellhousing of some sort. It looks as if it is made out of some kind of heavy duty steel. So I was happy about that but to sit at a red light for a period of time will make my leg tired so I usually throw it in neutral. If you are going to race the car alot then I would go with the kit that is more suitable for that but if you are going to drive the car often on the street then keep that in mind also.
