Im sorry, but having spent a good 15/20 minutes yesterday researching what was possible so Grundy can fit these wheels, Im not really down with this advice.
We have proven to him that hes got various options without downgrading the brakes or getting new rims, and I really dont see what lowering the car on the shittest coilovers available is going to achieve, if you are only looking for the camber then topmounts are a lot cheaper than coilovers.
Without being funny, if he'd had some decent advice in the first place he wouldnt have had the problem, to continue giving inaccurate advice isnt going to help. Apologies if that soudns harsh but the guys is going to spend twice what some arch rolling would cost only to achieve a reduction in braking performance, thats crazy.
The car needs lowering anyway to get the look I imagine he is going for in the end. D2's are actually very good coilovers for the money, they have near enough the same adjustment as high end suspension.
As I have said already, the first comment was in jest. Second one is the most sensible option and the third one is the best if he REALLY doesnt want to change the wheels.
And Arch rolling is permanent, the rest of the options aren't. Some people don't like a decision for life
your missing the point of the on coming rocket bunny kit with the permanent thing tho
