After a wee bit of advice:
On track I quite often suffer from the tyre rubbing against the arch liner (fender) during compression of the suspension. This is causing a braking effect which is upsetting the rear end during high speed corners, and also makes the steering very 'grabby' i.e. not smooth.

Set up:
Car: GT86
Front ride height: ~330mm / 13" (wheel centre to wheel arch)
Rear ride height: ~342mm / 13 1/2"
Sway bars: stock (I have not fitted adjustable endlinks)
Suspension: KW clubsport (6kg springs I think)
Alignment: Front -2.5 degrees, Rear -1.4 degrees
Wheels & tyres: 17x9 ET 42, 235/40R17 Nankang NS2R tyres
Misc: Whiteline roll centre adjusters / bump steer kit fitted up front. SPL Titanium rear arms. Stock bushings. Left side rebound adjustment siezed on full soft (although still had rubbing when it wasnt siezed pre winter)

Thoughts:
Sway bars - one size up both front and rear (I like the balance as is, would allow me to tune the set up a bit easier)
Raise ride height - dont really want to - I dont feel the car is too low
Revalve for stiffer springs with a rebuild - Scottish roads are not as flat and well kept as american roads, and whilst the car is currently my main car I dont want to go too extreme with spring rates to make the ride intolerable for the majority of my time (closest track being 3hr drive, 2nd closest being 6.5hrs)
The car does seem to 'roll' a bit.
