Luckily the track nearest me is pretty smooth so shouldn't be bouncy with a firm setup.
I'm also warming up to the idea of kw v3 a little more even though I wasn't really impressed on my friends 335i and just don't think I'm a fan of progressive springs.
I'm still stuck between kw, rsr, hks and now after reading some surprisingly good reviews of the tein flex z they are also in. Hard part is I can only find test on brz/frs so it's not apples to apples.
It does seem most of the coil over options do increase the springs rates however the rsr do not (yet they do on the frs which confuses me more, like did they not do their research). Kw runs a little firmer front but actually a softer rear. It's odd on other cars it's seems they are all much closer to each other but on the z they are all over the place which makes it hard to get any idea of how it will ride.

I can certainly elaborate more. the IVs are a street oriented setup. They are also a progressive spring, so keep that in mind since you say you are not a fan.
When I say rides better than stock, I mean ride comfort. They are softer over bumps and transitions, even on the stiffest setting. These are not something that would will run closer to full soft on the street and then turn up for the track. I had to drive them at full stiff all to time to combat body roll and the suspension bottoming out.
I would recommend them to someone wanting ride height adjustment and comfort that doesn't want to do super low setups. The guy that bought them from me is still trying to make them work on the track and is now considering changing the springs to get better performance on track. He's already done sway bars as well.
I did quite a bit of driving on them at the Tail of the Dragon before I sold them. They didn't seem to handle quick transitions or harsh bumps well and ultimately decided to go to a better setup to accomplish my end goals and not continue to tinker with them trying to get better performance.
For what you want, I'd look at some of the Stance lineup with swift springs. Talk to Corner3 Motorsports since they are somewhat local to you. They deal with street/track setups with these cars a lot.
