Wheel Help needed Please!!!!

[daveybtv]

I have Decided on Rushforths Super Spoke with brushed centers and pollished hoops, my Question is 17''s or 18''s? I emailed Jason and he said my Track4s with 13'' roters should clear the 17''s, if they clear is their any advantage to going bigger?

I have searched for 2 days and am hard pressed to find any pictures of this wheel in 17s, I just think 18s are too BIG for The 78-83 g-bodys. Any Help out there or thoughts on size, any pic of Malibus on 18s would help Thanks guys.
