Back Spacing-1970 Firebird/lookin' For Wheels & Tires To Buy Also !

[ALLACTIONMAN]

Hi !
New to the board(rookie).
Looking for someone, anyone(I know you are out there), who has maxxed out their 17" tire/wheel combo for this car(70-81).
No rubbing, etc.
Any info would be greatly appreciated !
I have followed the links, no one really states if their suspensions/wheel wells/lips, etc. are modified.
I am running a 16x9 1/2 on the back w/a 255/50/16 and 16x8 1/2 on the front w/a 225/55/16 there.
I would like 17x11 & 17x9 or 9 & 1/2 front...prefer the latter,larger size.
I have 700lb coils on the front, 160lb leafs on the back...
Global West suspension front to back(no rubber on car), so, no suspension deflection to worry about.
Right now I have about 2 inches front & 3 inches rear of space between the 16's & the wheel lip(vertical).
I mounted the 9x1/2's on the front w/no appearant clearance issues.
The rear measures from the widest part ov the section width ov the tire to any interference=1 & 3/4"s.
I know someone has run a big combo w/out mod's, let me know !
I can't get any sleep, I need to get a set soon !
FOR SALE ?
Let me know what ya got, cash in hand.
Thx!
