G-Body Guys, Wheel Fitment

[GBodyGMachine]

I am trying to figure out the widest wheels I can run front and rear. It is kinda hard to measure since my car is torn apart and rideheight is not yet set.
I am going with 18's. I have a frame notch in the rear, and tubular UCA's and LCA's in the front.

HOW WIDE?

Kind of depends on the actual ride height. For sure you could go w/some 18x8's up front & 18x9.5's out back (w/a frame notch) w/o having the tires stick out past the fender-lip.

For rubber: 245-40's up front & 275-40's out back. That should help keep the suspension planted.

I'm running 18x8's front b-body spindles and global west arms 4.75" backspace 245/40 (5" would have been better) and 18x10's rear 5" backspace 275/40.....no frame notch yet..slight roll of the lip. when it needs tires again its getting notched and a set of nitto 305/45's (maybe with a little more sidewall flex I might gain some semblance of traction lol)

the 9.5's I had on the front were a set of vette 17's that I used a set of billet spacers to mock up....they are to much for a "driven" car ...i.e. I saw lots of rubbing in the future....I can't remember the exact backspace as its been about 8 years ago I did that...sorry

GBody,

I run a 17X8 TTII 4.75 BS Global west upper arms with
a 245/45/17 BFG KDW's Rears are 17X9.5 TTII with 5.00
BS With 275/40/17 BFG KDW's.Iam running UMI performance
rear lowers and uppers (control arms) rear swaybar,and
the rear fender lips are rolled.I don't think you will have
any issues with 18" or even 19" wheels.I just purchased
this little tool for wheels.Not bad for $99.00 bucks and
will help me in future wheel/size projects and takes allot
of guess work out of wheel/tire sizes..at least i think so.

Good Luck,

I'm running 18x8's front b-body spindles and global west arms 4.75" backspace 245/40 (5" would have been better) and 18x10's rear 5" backspace 275/40.....

Do you think a 18*8 with 4.5" BS would work at all in the front? I have a stock setup minus hotchkis lowering springs and belltech spindles(might change back to original)

[SicMonte]

well here we go.

I have the rear frame notched..as you already know. Im running 17x11 rears with 5.5 bs. There is still some room left over in the back so i could add .5" of bs to put the wheel better under the wheel well.

the fronts are 17x8 with 4" bc...so it is a centered hub.

18x10 4.75 backspace will fit I have 18x9.5 on mine

Thanks guys.

Camaro SS 17in. ZR1's (17x9 I believe). 275/40/17's all the way around with 2.5in. spacers in the back, 2.25in. in the front. B-body spindle swap and stock drums in back. No rubbing so far.

[355_79bu]

I don't know if it will be much help, but I'm running 17x8 5"bs in front, 17x8 4" bs rear on my 79 Malibu. The car has Global West front upper control arms with b-body spindles, and Global West Negative roll springs on all four corners (fronts trimmed 3/4 of a coil)which lowered the car around 2" front and 1" rear. 245/45/17 front tires, and 255/45/17 rear tires. I have absolutely no clearance issues front or rear.

[BLWN1]

[355_79bu]

What suspension are you running and what size rear tire????

Jeff

[malibu9in]

air,2754018

[mone]

wats the rear width?

[malibu9in]

its only 9 inchs. surprised huh?

[mone]

so its 18 by 9 in rear....What kind of lip u got in rear?Any side shots to see wheel depth?

[SicMonte]

hmm...

i have a 17x11 in the rear with 5.5 bs...with a 315/35/17 tire. it doesnt stick out at all..but is really close to the outside lip.

if i get a 10" rim...what bs would push the wheel in a 1/2" and would the 315 still work on that? I want to get the rim/wheel tucked under the car some more.
