will 15x9 +10 fit dc2's

You'll need to stretch the tyres, maybe 195/45 or 165/45(quite a bit of stretch but this will defiantly clear your guard)

Springs ain't good for wide wheels and lowering unless its very stiff, cos when you bounce, it will smack your guards.

You'll deifnately need camber arms, rolled guards

Depends how low you're going to drop
