The Koni yellows do very well with lowered cars. I'll send you a pm in afterwards on pricing. I have the yellows on my Boss right now, they offer a hefty range of adjustability and paired with the right Springs (BMR) they would do very well at the track. The BMR rear spring rate I beleive is right at 160ish, so with the adjustability you could easily run at the track and on the street.
