seems a bit high for my liking
iirc subaru recomend 34 front 32 rear
i run mine 31/29 , , on track 23/21

it doesn't matter what make the tyres are . . but 215/45/17 are the wrong size for a my00
i use 215/40/17 or the other option is 205/45/17
try 33/31

When i had 17's (215/40/17) i used to run 33/31, now running 18's (215/35/18) and use the same pressure.

For each 50kg or so add 1psi over the Subaru recommendations. A petite female will be IRO 50-60kg with a med to large male 80-100kg. Tyre make and size has nothing to do with pressures, it's all relative to the vehicle weight.

DAZZA, I am surprised that you actually reduce pressures on track and by such a significant amount. I usually go up from 34/32 to 44/42 on track. The excessive cornering forces combined with such low pressures must wear your tyres very quickly and risk pushing them off the rim.
