you'd probably get the best feedback in the suspension forum.
if you want to daily drive the car, as well as not upset the roll center and/or create bumpsteer issues, bilstein HDs and springs from Shine are probably the way to go.
are you interested in running in ST (street touring) or SP (street prepared)?
ST (for solo2) is the best, and cheapest way to get started, after a season of seat time, you can then decide what sort of budget you'd like to spend on the car, and then choose the specific parts you put on the car from there.
the most competitive SP cars start getting away from actually being streetable all together.
