Good day folks I am customizing a 3rd gen 1986 Monte Carlo LS slowly.
I would like to get a wider track on the front end to match the rear end.
funny story is most are not able to tell what I have LOL
I want to widen the track 2 to 2.5 inches and looking for options on how to do this.

Thanks,

 

I'd go with a new set of wheels with a smaller backspace measurement / higher negative offset. Thatll push the wheels further out and can be tailored to exactly how far you want them pushed out on each side within the limits of the wheel of course.

Another less desirable option is wheel spacers, but I would be leary about running that much spacer - 2.5" on each side is really going to add leverage on the wheel studs and may leave you with insufficient thread engagement on stock studs.

 

Thank you @bumpin96monte - currently have 16 inch Iroc wheels using 2" hub centric spacers on front, car needs 12 inch wide all around
I have a custom Currie rear axle and want to have the same stance on the front without using hub spacers or deep offset wheels if possible.
The wheels is not a bad idea just concern over the horse power and handling. LS conversion @-500 Hp conservatively.

 

Yikes, thats already an awful lot of spacer. I still think wheels are a good option though for the easiest way to do this. Looking online, iroc wheels look to be about 5"+ backspacing depending if they're front or rear wheels. Taking your 2" spacer, and an extra 2" for the added track width, you'd be down to 1" backspace. Not sure I've seen 1" wheels, but there are definitely 2" and high 1s available.

The best way would probably be a combo of width and backspace. Add a few inches of width (looks like irocs are 8", a 10 or 11" wouldnt be crazy) and and you could take a couple inches off backspace getting down to the 3"s. All with a simple bolt on wheel set. Not sure you'll find anything easier that that.

I'm not getting what you're saying by this- 12" wide tires?

Its certainly possible to do it without wheels and spacers, but it could get a lot more expensive. I know nothing about that body, so I've got no idea whats available. The 3 options I see though from cheapest to most expensive:

-Spindles with pushed out hubs. May need to be pretty beefy to push it 3"+ off its stock axis though to keep the same strength. Really hate to be adding that much weight that far away from the body.
-Longer upper and lower control arms. Pushes the spindle mount out. Would probably be the easiest to fabricate if none of these options are available off the shelf.
-Modified body mounts to push the control arm mounts out further. Probably would have to be a 1 off custom job as it would require hacking and reinforcing the body.

Curious what the hp has to do with front wheel width and backspacing? You're not doing anything odd by going with a wider wheel and less backspace, could be 1000 hp and still work just fine. Look at something like a new Z28 or ZR1 - they're 500+ and run 10.5 - 11" front wheels.

As far as the handling, who knows - you'd need to consult a real suspension guru for that.. You're hanging the weight further from the pivot, likely adding weight (unsprung in almost all cases) and really changing the track width. Also potentially changing some suspension geometry depending which way you go.

 

Actually you have a 4th Generation Monte Carlo here the 3rd Gen would have been like an 79-80 I think.

 

yeah @drivernumber3 you are correct 4th gen thanks should have known - I have had 2 1980s - well 3 one got stolen and parted out in 1990, another spun out and wrecked 2007, and the last I frame off restored and gave back to my dad 2014 - he did not even recognize it as his.
Love 3rd and 4th gen Monte Carlos the ride and the feel of them.
