Lowering Springs

[david_12121]

I just installed some Enkei 18X8.5's with 225's for now, which has very close outer diameter compared to stock. A little lighter though.
So it's all good except that the wheel gap is very noticeable, especially with the low profile tire.
I really want some coilovers but all my money is going into a V8 RX7 project I have. (For those who remember my plan to put an LS1 in the SVX, I decided to first do one to an RX7 and do the SVX next year)
I've been looking to find some for the SVX but failed, so is there any other car's that is compatible or do I need to get one custom made?
What I want out of it is about 2" lower in the back and about 3" on the front, but anywhere close to those will be fine. I also need it to be very stiff as I don't really care much for comfort as I haven't been spoiled with it over the past.
Thank you guys in advance.
