It's a straight rail sportsman , Howe shocks , quick change ...don't really know a lot about it . i do know  I need to get the ride heights up or I'm gonna rip the nose off 1st lap. It's a bumpy 3/8 mile track that dries out and you can lay rubber by the  of the night. Looking for a base set up , spring rates and size of springs etc . I don't own scales , so, could be a while to get those numbers . Any info would be awesome . Thanks
