The Eibach with its adjustability might be a better way to go if that’s the case. As for dampers I have not tried either the bilstein or Koni for this particular car but I think I would lean towards the bilstein simply because they typically have a firmer low speed compression damping (more of a digressive tune) than the konis (the konis damper adjustment is rebound not compression). You can use rebound to tune understeer/oversteer but with the soft oem springs and konis softer compression (typically) I don’t know if you’ll get the support you want. Maybe go Hotchkis with konis and use the dampers for tuning or go bilstein with Eibach and use the bar setting for tuning but one way or another you’ll want to be able to have some form of adjustability so I wouldn’t go Hotchkis bilstein.

thanks for the input ,seems that I have a lot of pushing all ready car doesn't seem to get lose in the rear and pushes the front instead of turning , im sure my foot is not helping as I have a heavy foot but am working on theat I have about 18 events under my belt and only want to do better thanks

My guess is the car isn't as pushy as you think. When I first got started I had the same mindset. As time has progressed and I've learned to be a better driver, I've actually stiffened the front up more to account for getting back to the gas earlier and not losing the rear end.

Two big tips:

1. Get ahead on your inputs, steering and more importantly, braking.
2. Use the throttle to get the car to rotate better.

thanks , as I am getting better with each event I attend I find myself pushing harder , just need to slow down to go faster

Yea I’m still playing with the balance myself and thought I had it dialed, was great in the dry and felt completely neutral. Now after a wet track day I’m looking for a body shop to repaint my front and rear bumpers (oops). Luckily I was going slow on turn 3 at leguna just getting onto the track and the rear end spun so fast I couldn’t believe it and ended up bumping the tire wall. Now I’m rethinking my sway bar balance because if the wet is any sign to how fast it will let go at the limit in the dry then I need a little more warning then that.

You can't compare wet and dry driving as they are totally different. You can't toss the car in the wet like you can in the dry. Your right foot was probably the issue lol. Tires are a big factor to minimize hydroplaning. Race teams have a total different set up when running in the wet. Rain tires and raising the ride height for starters.

Yea probably a fluke, kind of a perfect storm of cold tires, cold track and very first turn being wet, also sways were set to my medium/medium dry setting and dampers were set to what I liked last time (which was dry). I'm was also guilty of not really understanding what the ecutek traction control did vs vdc. I'll be sticking with vdc in the wet, it seems ecutek delays the stability part of vdc and not just the wheel slip traction portion as none of the diagonal braking kicked in or anything and it did later with vdc on going down the corkscrew. Once I set the bars soft/soft the next session it was a ton better (maybe should have only softened the rear) but still a bit of a handful, probably needed to soften the dampers and ideally I would have liked a milder throttle response for that day, may be looking into the ecutek Bluetooth for that. Ideally I won't ever be doing another wet track day but it had been dry all season and then was too late to cancel.

Wet tracks can be fun or a death ride. It's how you go about it. My first wet track. I started slow and slowly worked up some speed. Testing where my grip was and wasn't. It's fun when you can hang the rear out, or do a 4 wheel drift.

But when you turn the wheel and NOTHING happens.

You KNOW you was a bit too fast! When you get back to the pits. You start pulling seat cover out of your butt.
