Just attaching the copy of the latest running from this weekend. Having had a few weeks off since TITC, time to get back into driving again, so I headed to the local indoor asphalt track.

I started out with an adaptation of my TITC settings, but with much softer roll bars all round. Car worked well, but seemed to be missing something, and was crashing over the bumps a bit. No real vices, but didn't feel fast... so took it back to the pits and decided to stick on Steen's settings (or as close as I could get) from the last ETS..
Well, that made a massive difference. Car was much better over the bumps, but with such softer dampers it was really stopping in the middle of the corner.

Next few runs had a play around with the dampers and springs, trying harder damper and spring, as well as Asym and Sym. Overall, the spring rate seems to be good, but the damping needed to go up, and I tried going as far as I could without altering the spring (so 3mm out on A from Steen's). This was too far, so backed it down to 2mm out, and that felt pretty good. However, the car still had a tendancy to over-rotate mid-corner if I got aggressive on entry, so wasn't so consistent.
On the Asym and Sym comparison, the asym felt really not nice to drive, really initially reactive, but then completely numb... it was so bad I pulled the car off the track after 2mins to put the sym back on!

I switched out tyres from 28's to 32's at the end of the day to try and have representative few runs on tyres similar to what I'll use next weekend... surprisingly the car felt pretty good, although could do with softer damping now, and the over rotate tendancy was still there. Also, given the low temps (~8°C!) the tyres took quite a while to heat up, but once they were there, and I got my head round driving it, popped in a series of laps with a fastest of 11.9, and a average of 12.1... so again, pretty consistent runs, which I'm happy with. Car was much more compliant over the bumps and ripples, actually felt like for the first time that it was riding rather than smacking them. Big improvement for sure.

Anyway, by that time it had got quite late, so left on my list for next weekend are to try a slightly softer rear spring, more rear camber, and overall lower damping/spring, to try and get the heat generated quicker. We'll see how it goes then... hopefully can get a decent run in, and even if the traction is super high I know that they'll be no hint of traction roll for me
