My set up is close dimensionally to what you are thinking about. I have the below spec wheels and tires on with Dinan springs, providing a 3/8 - 1/2" drop. I originally had the Conti EC DW with 255/40 up front, bad rubbing with max camber (no shims, just shoved struts inboard as far as they would go). With 245/45 - no rubbing, but it may also be because the 255s wore away some of the inner fender liner too....
RAC RG63 wheels
18 x 9 et38 w/ Conti Extreme Contact DW 245/40
18 x 10 et27 w/ same tire, 285/35
Dinan springs
Hope you don't like the wheels too much, we had only 28-30 sets made, if you can get them off of somebody more power to ya, they won't be making another run of them.
I just realized I don't have any recent pics with the springs and different front tires on...will have to try to correct that problem...
