888 Tyre pressures

Fitting my 888's soon and interested to know what tyre pressures these should be run at for road and track use.

I will be fitting 225/45/17's to standard speedline rims

Thanks
 
There was some useful information posted in a tyres thread not so long ago, I think generally people start off at something like 26-28 psi front and 30 rear.

It all depends on the day though as well though I've started from the above and tweaked as neccessary.
