Wheel Fitment Guide

[FastCraig]

305 45 17 installed no frame notch or tub, just cut the lip in the rear wheel wells, and it is the same diameter as a 275 60 15! I know it's an old thread just wanted to update 🙂
Oh and I have 17x9.5 wheels, with 5.5" backspace running 1 1/4" adapters so I have the ability to do my 8.8 swap in the future

Horner, I have a set of 17 x 9.5's with 275/40's on them that I would love to mount on my 83 Monty. Are you running the 5.5 BS on the front end too?

Is anyone running 17 x 9.5 Vette wheels? Will a 9.5 wide wheel fit on the front of an 83 Monte SS?

85 Regal
17x7 wheels all around
4.00" BS
235/45R17 Tires
No issues at all and couldn't be happier with the setup. Most likely lowering in the future.

Hey there, I'm looking for some bigger wheels for my '85 regal. (Aka princess v*g*na)

Something that will fit the muscle car style I'm going for and won't look bad on matte black.

The wheels I got going on right now are waay too small.

Looks good, do they fill the wheel well all the way to the lip, any rubbing?

Good afternoon all!

Took a while to get through all 27 pages.

I have a 1979 Monte that has had 15" Ultras that look like American Racing "Gamblers." With a recent engine upgrade I'm looking to move to a tire with a little more "bite." However, as discussed throughout this forum, it has become difficult to purchase performance tires in a 15". So, I've decided that after 20 years it is time to upgrade her shoes. I have two questions really.

First question: Are the fender tolerances on my 3rd Gen Monte similar to the rest of the G-body family? I've been looking through here and it looks like you can fit quite a bit of wheel under these. I want to fill up the fender wells on all four corners. I have to admit that the math you guys have figured out is pretty impressive, but it makes my head swim a tad!

Some details: A few years back I installed a Hotchkis suspension kit that lowered the ride height about 1.5-2in. While I am looking to modernize the look a tad, I want a LITTLE sidewall in the back, but nothing like I'm running now. How big can I go in the wheel and tire dept? Was thinking either 17s all around or 17s in the front and 18s in the back.

Anybody got pictures of their 3rd Gen with 17s or 18s tucked up inside? Did you have to roll the rear fender lips?

Looks like 4.5' backspacing seems to be the norm? Something 9in wide should be OK as well? 9.5in wide? I'm not concerned about all four being the same size as I don't rotate them anyway.

What additional info can I provide?



Second question. I have my WHEEL choices narrowed down to five. All are modern editions of more classic styled wheels.

Standard - U204

Standard - U104

VN409 TTO 2 PIECE

VN515 CLASSIC TORQ THRUST II 1-PIECE

VN615 TORQ THRUST II

I am struggling to find pictures of any 3rd Gen Monte Carlos with these wheels on them. Anybody have any? If not, how about a solid shot from a similar G-Body?

Here is what mine looks like now:



Thanks,
Russ

how do you like the eibach lowering springs? i went to there website, and the only kit they offer only lowers 1' in the front, and 0.8' in the back. i think i need a little more drop than that. the site also doesnt give a price. how much did you have to pay?

I had the eibach springs on mine and the ride is great as long as you put new shocks. The look is actually probably just right for most people. I run an 18 x 10 in the rear and 18x 8 up front.
