Sounds the same as mine, but I was doing it more into Pif Paf (that's the slower chicane that looks like a hairpin): lifting off slightly on the way in to let the car oversteer until it was pointing the way I wanted and then using more throttle. I seem to be getting good at doing that on chicanes and dual corners like that: let it oversteer on the way in because you know you're about to turn the opposite way anyway. Works well on the twisties after Hatzenbach, and at Hockheim (I think that's where I mean).
This is what's so great about my car now Chris has worked his magic: it feels like you can just play with oversteer and understeer all without any drama.
What I have found works really well for me is setting my rear dampers stiffer than the front. This means the rear rolls slower into the corner (so turn in oversteer), and takes longer to roll back on exit (so exit understeer and more rear traction to overcome it). I imagine you'd like that.
And I hearby take back what I said about caster. I thought it was great yesterday.

I've got some longer front springs sitting on the desk in front of me I'm going to raise the front end a few millimetres (the driver's side is 4mm too low at present anyway, hence the front lip scrubbing a little as I turn into the hairpin from the banking).
Then it's a question of waiting for Powerflex to supply Chris the ARB bushes and I'll be over there to get the stiffer Tanabe rear ARB installed and I can then play with the balance of the car by adjusting the drop link length, front and back
I felt that the rear of the car had too much roll on track with the rear OEM ARB - now I have the anti bump steer kit etc, the problems which I was seeking to address by (probably wrongly) returning to a rear OEM ARB should not resurface (fingers crossed!).

Just spent ages looking for a map of corners so I could see what you were talking about (there's one on BAT's site ).

I feel like I've got some of the bumpsteer back. The rear ARB makes things worse over bumps with losing the independence of the rear suspension (as Nick had said somewhere). It's definitely not as stable as it was pre-ARB, but better overall with less roll, and less of that slightly unpleasent feeling you get when one end rolls more than the other.
Whiteline have a thing for stopping the ARB moving side to side (I think the OEMs have them), so I might get those for the rear and see if that improves things.

Pif paf isn't really a chicane. It's a lefthander. Hug the kerb around Chapman, then turn once to the left, and the straight before Kirkby gives you enough time to get back on line. That's one of the places on track I gained a lot of ground on traffic. And that info was from lower's instructor via lower
I hadn't had a chance to get to learn the circuit, there was too much traffic, and because i was getting the lines right (ie under instruction) i kept catching other cars.
I ended up hanging back, doing 3 quick corners, hanging back, another 3 quick corners etc.
