I was told balance > maximizing camber @ one corner.

 

Add more toe in in the rear.

And what do you mean by tail happy? When in the corner is the car loose? What makes it get loose?

 

In recent months the car will step out the rear 1 or 2 yards in 2nd gear on a sharp turn right of traffic circle on spirited driving, with all traction controls switched on. I primarily suspect my PS4S tyres are giving up, or secondly an alignment issue. Tire pressures are as per recommended for street and running 245/295. It is a recent issue I have noticed, but I have felt for a while that after the last of 3 track days my PS4S's aren't quite gripping as they used to.

It's likely the tires, but thought it worth checking alignment. Tires are about 1 year old and <4000 miles, but had similar issues years ago when using PSS on an M3 for track. I know people say the PS tires don't heat cycle, but I'm not convinced.

 

Any update on your alignment specs @ RoadrunnerGTS? I have a '24 GTS coming this summer and I want to have my dealer optimize the alignment for backroad fun and the occasional AX.

 

The above post #17 works well for me

 

Noted.
Thank you

 

Actually currently in shop getting Bilstein B16D coilovers, and shop will do a different setup. Will post it.

 

Just got myself a fresh alignment to start the season. Tech said rear is good enough but to get more negative camber up front would require Camber plate

 

Maybe it is different for the GTS but, you are running the wrong direction for front to rear camber off-sets. At least on the GT4, you would run about .5 MORE neg. camber in the front than the rear.

I would think that with your camber settings, you would have a lot of understeer.

 

I think you are right but I think the tech reduced quite a bit of existing understeer from before (alignment from factory) so I will try this setting for a couple of track days then do another one based on the progression of my skill level. I haven't hit the track for 20 years so the tech is trying to protect me LOL

I told him I don't want the outer edges of my tires destroyed after a couple of autocross and track days....
