Some pics of my updated setup
Front:
TrofeoR 265/30-19
OEM 10" ET40
REAR wheel plus 25mm spacer
3,1 degree camber
Rear:
TrofeoR 295/30-19
OEM 10” ET40 wheel
2 degrees camber
The car is just very sligthly lowered to Öhlins Road & Track default setup
The 265 in the front sits much better on the 10" wheel. I felt a sharper steering response, although it might be placebo
I also felt a very small increase in tramlining, still on a very nice low level in general. This increase is maybe more due to the wider track (more scrub) with the ET/width change rather than the wider wheel stretching the tire a bitmore. Maybe. I think a 20mm spacer rather than the 25mm I had in hand would be more optimal. But this seems to work. I'll keep an eye on rubbing issues on track.
