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!

check out hotchkis's orange camaro, they have a link to it on their homepage if you do some navigating. They put 17x11,17x9.5, they list the backspacing #'s, although every second gen i have seen with 11's on the back, the rim stuck past the quarter panel lip by just a hair
Uh-Oh looks like these second gen firebirds are starting to be more popular!

[ALLACTIONMAN]

Hmmm, could'nt track any specs on the Z-28.
Giving them a call today, though.
Thx for the reply, what size 18's r u runnin' ?
Nice car !
Once I can figure out how to post pix I will throw mine on.
Anyone else out there with some experience in this area (back spacing,max wheel tire combos w/o body mods)?
Thx

[ALLACTIONMAN]

Whoops, I mean 19's ?!?!?!?

[yody]

only 19x10 19x8.5. i could of went 11, and 10 but i didnt' want to deal with any headaches, or wheels sticking out

[DB Z28]

i,m running 17x8 245 45 17 front 6in backspacing , rear now 17x9
275.40 17 6 in backspacing . going with 17x11 with 6 in backspacing 315 rear tire this is on a 79 728

[ALLACTIONMAN]

Have you test fit the current rear wheel/tire combo on the front ov your car ?
Have you tried the 17x11 yet ?
Like, someone elses you could test fit.
Thx

[ALLACTIONMAN]

Yodi, what is the back spacing on the 19's & what is the ride like ???
Thx

[yody]

i forget the backspacing #'s. i will try and look them up. It isnt running yet so i can't tell you about the ride, however i picked tires with a decent sidewall so they won't be like rubberbands, hopefully the ride wil be decent

[ALLACTIONMAN]

Ther has to be more "pro-tourer's" out there with big tire wheel combo's
that FIT the second gen. Firebird
Help a brother, thx
E-mail me if you want @ [email protected]

[yody]

sometimes you just have to do the work yourself if you want positive results, it never pays to just have someone tell you what will work. What if someone tells you what works, and you put it on your car and it doesnt' work?

[ALLACTIONMAN]

I have measured & measured & talked to about a dozen people w/conflicting stories...
I am holding no one responsible for results, just hoping someone had a working package...not a mistake.
I get alot ov "I wouldn't suggest it", etc.
Someone out ov all the second gen's should have found the magical back space, I would think...
So, instead ov calling around I figured I would try a huge group.
thx

[ALLACTIONMAN]

Well, no luck w/back spacin' info or a good deal on some 17's yet so....
In the wind, 2 lane black-top is where I be...
"Seat time" is what it's all about !
See ya on the road or not. :comp3:
Thx for everyone who thru in their 2 cents worth, it is appreciated.
See ya on another topic !
Cheers !
Off to the "vanishing point" in "60 seconds"...

The Hotchkis Camaro is using the following setup:

Front 17x9.5" with 5.5" BS
275/40/17

Rear 17x11" with 5.75" BS
315/35/17

Hope this helps.

[MrQuick]

You know when it comes to BS i've alway found that every car is different.I just watched Chuck Hanson on HP TV and he used a mount mate and came up with 17 x 11' with a 6 1/2" BS to fit a 315...no mods...BS alright. I've never had a 6" BS rim fit with no mods.Anything past 5 15/16" is gonna wack the inner well.Cut the well out and you'll wack the shock. I say find a size,get the dish the way you want and modify to fit. Its easier to modify an inner well than a quarter panel.
A 17 x 11 with a 5.75 bs is alot more realistick but I like to lower the car down on the rims. So that would not work for me.

[c.schulz]

I ve had 17x8 with 4.5 BS and 17x9.5 with 5.5 back space with 245 and 285 with no troubles at all.Rear wheel centered up very well.But I agree with Vince, make sure sure you measure your own car.Side to side tollerences on these car are not friendly.Again measure your own car and use these numbers as a starting point.

I've been trying to sell some 2ea. TTll's 17's to Vince for some time now.
17x11 7 3/4 bs mounted with BFG KD's 0 miles on both. $850 Shay

[MrQuick]

Hey Shay, you still got them rims??? huuummmm ...your evil.... damn is that with 315's?? ahhhh must resist

[David Pozzi]

This was recomended for a second gen Camaro:
(FRONT) American Racing Torq Thrust II 17x8 w/5"bs and BFG G-Force KDW 245/45/17
(REAR) American Racing Torq Thrust II 17x9.5 w/5.5"bs and BFG G-Force KDW 285/40/17

We have this combo on our 73 Camaro, only we used a 4.5" ft backspace since that was all that was available from vintage Wheel works. It works fine, no rubbing, maybe not as wide as you want to go.

THX GUYS (CHRIS,TODD,DAVID & VINCE)
HOTCHKIS SAYS "I WOULDN'T RECOMMEND THAT WIDTH" (HAD TO BEAT THE PISS OUT OV THE CAR).
THE 8 & 9 1/2 WITH 5 FRONT BS & 6 REAR IS WHAT I'M RUNNIN' NOW, NO PROBS.
