I'm running the Street Advance (Basis with damper setting) for SH Foz and really like them.
Unlike most coil overs (in the Foz range) that run "harsh" 7-9kg spring rates, these Teins have 4kg so are much softer without being too soft
I think that I could probably do with an even stiffer RSB (currently 19mm, but I think 22mm would be better)
I don't think that there's anything better (coil overs) for a street car. Unless you're after a much stiffer ride.
If spring rates are similar to Foz, I'm sure they'll be a decent coil over to live with
