I would say stick with what you have for now unless you have no local support for the car.
I assume you are racing and not bashing. If this is the case ask Hodgimoto (a.k.a. Todd Hodge) on his thread (

I am sure he will help you sort it out. As sosidge mentioned you will have to start learning how to tune a chassis. Spend your money on the XXX Main setup guide. This is probably the best book available for touring car setups..
Good Luck,
