Whanioz, I will be sorting some more club discounted days with BaT, and TrackactionOnline for some of the Northern ones
Keep an eye out over the coming weeks.

As promised (like any of you really care ) here's the results of my Torque app log - you can see it covers 4 laps, and also that the GPS seems to get a bit confused at times!
All good fun though

Having Derek there with the heat gun and making take tyre pressures and so on was interesting.
Geo as follows:
Front Camber: 1deg
Front Castor: 6deg
Front Toe: +2' each side
Rear Camber: 2deg
Rear Toe: 30' each side
Here's a brief summary (the coilovers have 40 clicks, and all numbers are clicks from full soft):
1) Coilovers set at 16R 20F (day to day settings) and tyre pressures at 32PSI cold. Pressures rose to 40PSI. Car drove pretty much as it normally does on the circuit, nice stable front end, a bit understeery at times.
2) Coilovers set to 24R 20F, pressures reduced to 31PSI, Tyre temp consistent across the width of the tyre, around 47C - Car drove like an S2000, grip, grip grip, then a quite sudden breakaway.
3) Coilovers set to 20R 20F, pressures reduced to 31PSI (had risen to 33 again), consistent tyre temp again - Rear end very communicative, a gentle squeal from the tyre and a nice slow slide - lots of fun but perhaps a tiny bit wallowy
4) Coilovers set to 22R 20F, pressures 31PSI, A nice middle ground, enough communication that sliding is about to happen, but easy to balance the car, and also to do a bit of messing about (as Ninebolts will testify), and easy to manage when I got it a bit wrong. Care needed for the first few corners until the tyres get warmer and the pressures rise to working temps.

I was on 28 starting on rears. The heat gun was handy though, could see the fronts were becoming overinflated on the track as the middle was hotter.
Mine is running a lot less toe which is odd as we both were setup at WIM. Derek thinks we could get away with a bit more camber on the front

My settings were sorted by Chris at CG, and I just get WiM to replicate them.
FWIW Both places do a setup to meet your requirements, rather than a "one size fits all" approach.
I might begin to use a little less rear toe in future though.

I use -2 front and -3 rear which I'd say is a bit aggressive for road use. Tramlines a fair bit on bad surfaces. Had -2 all round previously and that was nice.

When I've tried it stiffer at the front, it makes getting on the power more difficult and can be a bit snappy.
Except you seem to be saying the opposite (higher number was stiffer?).

The best setup was slightly stiffer at the rear (22 vs 20), although it's worth remembering that the front springs are stiffer on my car 400F/300R.
The softer the rear, the more slideyness was there, and more communication that it was slideytime.
