I found a Local guy selling some rims in A1 condition.

their 20" coming off 2005 Grand Prix with tires 245/35ZR20 95Y

My guess is it will fit no problem considering the grand prix is 5x115.

 

Dont do it!

Monte Carlos were not meant for 20's !!!!

 

they will fit as long as backspacing is 5.5-6 inches. its same bolt pattern

 

I'd have to agree with this LOL.

I'm not a huge fan of 20's unless it's lowered and still has a clean look. So I'd have to see them first

 

In other words, Franks monte happens to look good with 20's, I think there are a few others here who have good looking 20's, but Franks happens to be one of the best.

 

I agree, I think franks monte does look pretty good on 20's








i say do it but post a pic first , I guess it depends on the style of the rim in order to look good, also needs to be a little lower it makes a big difference IMO. Not so much in pics but in person it sure does lol
Here's mine on stock springs and then look at my sig pic

 

these are the rims for sale.

20 inch rims

 

NOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO.. they already look gay on the gp, don't put them on yours. 5 or 6 spokes is a good way to go with these cars.. there's the rare occasion where something like the moda md8's will look good.

These 20's might look good







and if they would fit these:

 

I myself am on the fence with 20s 0r 18s. I like 20s but the tires would be too expensive.

 

arent they cheaper than 18's? lol
