Tein SRC vs. KW clubsport

Yeah, most places... but NOT that road. Wait. The SRC are adjustable? beyond full soft I mean...

@churchx To provide a more thorough answer:

As grip went up and courses got faster, the Teins would really show what they were capable of (I'd not be surprised if they did well at nationals, assuming it's dry, for example). I so badly wanted to love them all the time. As grip fell off or surface got bad (one lot requires choosing fast transitions, or fast through the rough... I'm hoping to find a happier medium...) it became a struggle to keep the car behaving consistently well.

I've gone down *significantly* on spring rate to start this season, lower than what I think the Teins were suited for, but there's more to it as well. I'll be experimenting with spring rates. My previous comment about color might be enough for you to make some accurate assumptions as well, but I'm not really wanting to go on about it here. Suffice to say it isn't a lateral move.

What really is interesting is that, aside from one stretch of highway I drove a lot where the distances the cement was laid down lines up with some harmonic and it feels like the car is a seesaw, highway driving was never an issue - and that includes my wife, who likes to knit while we travel, and did so without trouble. Oh, and that one HORRIBLE road in Michigan, where I thought the car was going to fall apart.

And all this goes back to what I asked the OP: what needs to change? Because without that, ... who knows.

Note, I haven't driven more than 5 miles on the Tarmacs yet, so have zero opinion of them performance-wise.

Thank you for your detailed reply on my post.

On the setup I have right now, I can get on gas pretty early to go through the tight corners at track. The car felt a little pushy and on the corner exist, I do felt like I have to fight some understeer. I want the car to behave more neutral, but not too much oversteer to correct. My hks has 8k spring rate all around and my alignment spec is f-3.3 r- 2.5 o toe, and very slight toe in at the rear. And I do have basic aero setup, front splitter and rear wing. I know I could change the alignment a little and adjust my damper to give the car more rotation and more neutral feel. But I want to learn to how properly dail in a two-way damper. And I really wish that my damper has independent compression adjustment.

Stock swaybars? Square springs is common for autocross where people like a bit more push, and transitions win the day. Tires, and tire pressures? Maybe a tiny bit less camber in the back.

Don't get me wrong, every so often I needed to dial out some rebound but not compression... But almost always, it was both together. On the other hand, I can't really say much about wanting more knobs to try to target certain scenarios. For track stuff, CSG can definitely help get you sorted, but the SRC may well be a great fit for your goals. I would not look at the KWv3, they seem to have gone the direction of a street setup that can survive the track. RCE could also get you sorted really well, the T2 is a great setup (you might want custom spring rates though)

Stock sway and ad08r 245 40 17. Hot tire pressure is 36psi. I lean more toward SRC but Rce is definitely a good brand also. Thank you for helping and I will let you know of my impression toward Src on my next track day.
