Did you stop by on Sunday at Infineon? Sorry to blow you off - I was just trying to get ready early every session and be in the car a couple minutes early to get my head right before each sesssion.

I agree with the others - try disconnecting the rear sway first. I had lots of high speed push at Infineon but with no wing for the last session the car was too twitchy for me on that day. With one more session I would have disconnected the rear sway and run no wing. I would also have added more rebound in the rear but that's another story...

No, that wasn't me. My car's still in Los Angeles. When I get it up to the Bay Area, I'll be at Infineon, Thunderhill, and Laguna Seca as much as possible.

I'll try disconnecting the rear sway and adding wing and see how it drives

I don't think both are needed just try one thing at a time. They'll both help the situation.

Having 2kg higher spring rate in the rear than the front is back ward and a poor starting point.

It's very easy to pull your coilovers and swap springs yourself and that will give you the right starting point to then try the wing or the rear bar disconnect one at a time.

What is your ride height? Don't go too low or the suspension geometry will end up adversely changed.

Exactly. I'm trying to fix what I think is a poor starting point.

If switching front and rear springs, despite their different lengths, builds a better foundation, then that's what I will do. Also, I don't mind spending $100 to get a new set of front or rear springs if that's an overall better solution.

My car's only lowered about 1.25 inches.

Whiteline is a decent bar I had one for a while but I'm not sure it will be enough.

My springs are stiffer at the rear and with the saner on medium which is stiffer than the whiteline I still think I have too much oversteer on 17x9 255's all round

The saner might do the job but if I could I'd probably change springs.

Can I swap front and rear springs without any issues despite the different spring lengths?

Do you know how much longer the one set is?
I doubt there will be a problem but if for example your rear spring is the shorter one and the lower spring perch is all the way at the bottom meaning that's as low as you can go then the front spring will raise the rear of the car because you can't lower the perch anymore. Same goes for the front but opposite.
Usually there's plenty of adjustment on either end to make up for an inch difference in spring length.

The spring rate change might seem backward but I don't think it's as bad as you make it out to be. On an oem stagger type setup it'll definitely be worse but once running non-staggered I think it's the way to go. Or at least run identical rates from and rear.
