I have been looking at the handling kits for my 66 coupe from different manufacturers. On most of them when you buy upper control arms they give you a template to drill new mounting holes to lower the mounting point for the control arms. They say this increases negative camber and improves cornering. I was wondering if this mod is something that you can do to the stock control arms to get the handling improvement without spending $500 on a control arm kit. If anyone knows about this mod, please give me some info or tell me where I can find out about doing this. I have searched on the forums but have not found much info, I thought there was something called a shelby mod that was similar to this but not sure what that is. I would like to get as much information as possible about how to make the coupe handle better, they way I drive I need it ).
