My car is mainly a drag race car .. but i do auto-x from time to time

I have the QA1 coilover / shock in the back (stock springs in the back) .. also have the ST 35/25 bars along with pretty much every other supension / chasis piece

i need some suggestions on what settings to put my QA1s for starters ... my tires will most likely be just street tires (275 / 315) .. unless i borrow a friends R comps (would i want to set my shocks differently according to my tire? )

sorry im a noob when it comes to settting up my suspension for auto-x

thanx
