Ever Since I bought my Coupe, 2 months ago, I have been trying to decide what aftermarket rims to get for her; I eventually opted for Apex ARC- 8s in Hyper Black. Normally one would go for either an 8.5” or 9” for the front, but these are only available with a relatively flat face, not the lovely deep dish that you get with the 9.5”, 10” or 10.5” versions.
My car is fitted with KW V3 coilovers which, due to the position of the spring and lower spring perch, require the use of a 5mm spacer on the front, even with the standard wheels & tyres. After a bit of investigative work, I decided that it would be possible to modify the upper spring seat/top mounts/springs in order that the lower spring perch be raised enough to get the 9.5”, deep dish, rim to fit on the car with either a 245 or 255 35 series tyre.
I have started this thread to keep you all abreast of progress as it develops!
This is the situation with the standard wheel and tyre, fitted with a 5mm spacer, so effectively ET36:
The ARC-8 is ET35, here it is fitted with a 5mm spacer, so effectively ET30 - I have raised the spring perch 25mm higher that where it was, to get it above the rim:

There is actually very slightly more that a 5mm gap & I have had it fitted with no spacer, but the clearance is too small to be of practical use, but I am hopefull that I could make some 2mm spacers! Next step is to fit a secondhand 255/35 to see how much futher I need to raise the spring perch - I hope to do that this weekend.
