Suspension guru help
i ran into 1le upper and lowers and a nice set of koni DA and a set of slp springs 450-300 and 185-115
should i keep the 1le springs or go with the slp ( i do like that fact the slp lowers it .5 inch ) or a totally different spring ????
the car is not my daily driver so its main purpose is agressive street and some road racing
the car pushes 400 rwhp
thanks for all you guys help


The other stuff sounds good too.
