Coy C5 Wheels

They are 17x7 with 4 1/4? back space??? I think.I talked to him about them a few months ago.

Edit: His name is DVJCUDA,here is what he sent me:

2 - Front

Wheel Brand Coys

Suspension mods big bolt from 74 dart sport

Rear

Wheel Brand coys
Size 17x7
Backspacing 4.25
tire size 255/45/17
Suspension mod ss springs and poly bushings

weight - they were the same weight as my 14" steel wheels wth 245/60/14's and I forget the exact weight right now
improving handling? yes, but I have poly bushings all the way around and front and rear sway bars... so it all works together.
