Need exact alignment, ride heights and in car video to diagnose.

949 alignment is quite aggressive on turn in. I would think if you don't have much seat time that this would be the best method of resolving the problem.

Also checking tyre pressures, tyre heat for Inner, Middle and Out.

This way you can start analysing your setup a bit more. Maybe too much camber, maybe too little camber etc...

BUT I agree with 14 mm bar being about right. I run a 16 and have had to compensate a bit as I was getting MAJOR oversteer in to corners..

A 14mm would be about perfect for my car too.

I think I still have the exact alignment spec. I'll look.

I'll measure ride height.

Does the video have to show me going off? I have only one and it's on a wet track so not sure how worthwhile that is. Plus need to put it on youtube so I can link it here and I'm not much of a computer guy. lol

We could tell you what you did wrong. In explicit excruciating detail

It would still be useful to see.

You're running it pretty high considering your 700/400 spring rates.

Try running OEM rear toe and lower rear 1/8"

This from a couple of weeks ago. I got one good session in between the rain. The first 3:30 minutes are me getting ready, so you can skip that, just after 15:00 minutes I go off. Be gentle

Car looks fine. Looks like you were still on the brakes too late and hard (too much trail braking) and spun it. Your reaction wasn't severe enough. It's good to steer slowly into the turn but when you think it's letting go, your corrections should be violent. You could have caught the half spin if you had snapped full lock left the instant you felt it going around.

I notice your heel-toe's are hit and miss. Sometimes perfect, sometimes clunky, sometimes no heel-toe. It's important to be consistent with that to have your corner entries and trail braking overlapping smoothly. In teh turn you spun, you were not overlapping smoothly and hung onto the brakes too long.

Because you have some power, I'd suggest the OEM toe in on rear and lower rear 1/8". Car looks good otherwise.

THIS

And what Emilio said. A little toe-in in the rear and lowering the rear end of the car should make it more to your liking.

Your biggest benefit would be to hire a coach.

I would put one day with a good coach up against 100 trackdays hacking around by yourself any day. Coaching, coaching, coaching. Even (and especially) pros have coaches.

Seat time will give you the reflexes to drive the car how you want. A coach will get you to understand what exactly it is you want the car to do, and where, on that particular track.

Funny...I was thinking about doing this. There are a couple of veteran ex-professional race car drivers who offer coaching at my home track at a reasonable price!

Thanks to all!!

Was that your first off? No offense but it doesn't look like you've had that much track time to be worried about perfecting your setup. Not really pushing the limits in the corners. If your not throwing a tiny bit of counter in, your not finding the limits. A fast auto-x course is a good place to practice this and get your timing, car sliding butt-o-meter, etc. calibrated. And at less scary, less car or tire damaging speeds.

I see you're in IL. I ran at the GPS track times day @ Blackhawk Farms the other week. They had some truly amazing instructors available to ride along or drive your car and coach. I'd recommend that event to anyone. I learned a ton.
