Ha, I wondered whether I would catch up with the tuned UK Boxster. Glad to hear it's going well.
 
I'm off to Spa next week and at Castle Combe track day on 22nd.
 
Will you be at the Silverstone Classic?

You sound to be busy ;-)
I will try to get to Castle Combe - need to call PCGB tomorrow to see if there are spaces left.
Best

Castle Combe is the 23rd, not 22nd as I wrote previously.

Some recent suspension updates:
 
At the rear, we fitted Tarett monoball top mounts and 997GT3RS rear wishbones replacing the GT4 (offset) top mounts and stock wishbones (with Powerflex camber bushing) - this was to improve the rear wheels' clearance of the diagonal control arm.
 
Also, I replaced the OEM rear cross member with the GT4 part (981 331 071 80) - the GT4 part being more robust.
 
I've backed off camber and am now running negative 2:40 front and 2:30 rear, which seems to be working with the medium front and rear ARB settings. I did try hard setting on the rear ARB but it was a bit too lively for me through Eau Rouge/Raidillon.
 
As someone observed, when you start how do you stop? Anyway I'm looking to try TPC Racing's DSC V2 Controller, which replaces the PASM ecu. I've heard some positive reports of its performance on road and track so we'll see...

I've bought a DSC V2 Controller from TPC and should have it in the car for Silverstone October 24th. We should get some structured empirical data with back to back runs with DSC installed versus running with stock PASM.

The DSC controller was fitted in October and after testing, the set up was changed in March by Centre Gravity to run more camber to better suit DSC and Cup2 tyres. They also stiffened the ARBs which are now halfway between medium and hard settings front and rear (one side middle, the other side hard) which worked well on Silverstone GP circuit particularly though my favourite test of Maggotts/Becketts/Chapel.
