I'd not bother with the random cheap ebay ones personally. I got mine second hand from E30Zone. Just don't mention drifting or welded diff's and you'll be fine.
Get a 'wanted - stiff front and rear shocks for a 325' thread up
You might well get a bargain, I did! (also read through all the for sale/breaking car ad's)
15" steels?
8 wheels to drift on then, and those BBS RS's look lovely!
