You may be able to use a 10" spring. Really all you're doing is holding the front of the car up since you're not concerned with taking corners. As suggested, talk to the folks who buy the "kit" from. They might have some other suggestions. Quote Selected

Thats what I meant by saying about the nose length, there is alot of over hang on these cars.But I would agree with Chuck, ask the company you are going to be dealing with and see what they have to say.
