Carrera2RS:
Well, greasy roads and the chance to explore limits at sensible speeds, well yep I can provoke oversteer, but easily balanced and the poise balance and behaviour is text book stuff, anyone watching would be fooled into thinking I was talented. It's coming close to reminding me of a FWD equivalent of an E30M3 (I had one for many years and was complimented on my driving around spa by a pro, I didn't tell him the reason he couldn't shake me off with slicks in a very low class BTC of some equivalent was the sublime chassis and near tyres as good as his slicks - Dunlop DJ01's)

This car has moved into the great category, I'm gobsmacked. If I'm slower on the track I'm happy too. It's a point and shoot roadie to enjoy day to day, I am actually excited about the drive to work tomorrow...... which I never expected from a GTi  :wink:

Carrera2RS:
I have had two glasses of wine since getting home, so my view might be more balanced in the morning !

Gents

I thought it might be helpful to set out the actual figs (recognising my last setup showed very small differences when back on the same rig, so accuracy to 2-3 mins is clearly a pointless challenge)

Front

Ride height 338 mm
Camber L -2 deg 10 mins, R -2 Deg 0 mins
Toe L - 6mins, R - 6mins (toe out)
Caster L 8 deg 13 mins, R 8 deg 14 mins
SAI L 16 deg 36 mins, R 16 deg 21 mins
Bilstein PSS10 setting 3/10
Neuspeed 25mm bar full soft
WALK
Tyre pressure 35 psi after a 20 minute normal journey (32.5 cold)
Tyre Pirelli P Zero 225/18 92Y XL MO

Rear

Ride height 324mm
Camber L -1 deg 37 mins, R -1 deg 30 mins
Toe L 6 mins, R 7 mins (toe in)
Bilstein PSS10 setting 4/10
Neuspeed 25mm full hard
Tyre pressure 33.5 psi after a 20 minute normal journey (31.5 cold)
Tyre Pirelli P Zero 225/18 92Y XL MO

I will still look to raise by some 5mm or so, mark very carefully the collars and experiment a little. I was looking to move from 335 F, 320R to 340F, 325R it didn't quite hit those heights after settling over a few hundred miles

the bruce:
Better go for 330 to 335 mm rear.  :wink:
I suspect I had the problem of too less suspension travel by myself when
I was as low on the rear like you.
This may have caused the sudden massive oversteer I had on 180° corner.

If you're going to do a new alignment try toe in on front.

Carrera2RS:
Bruce, tks

I will try raising the rear to 330mm.
