rim offset anyone?

i boughts my new granp prix gt (97)
i found a set of 20`s and can`t remeber the off set
i looked everywhere but no one knows it ,,
these rims state:
size:20x8.5
bolt:5x114.3 (4 ½ ")
offset: 34

would these fit with that offset with stock hubs?

you have them, just put one on the front and make sure it clears the brake caliper. Then turn the steering wheel all the way in both directions to make sure it clears the fender.

i don`t have them yet i`m not gonna buy them unless i know they will fit i need to know if that is the right offset i know i can clear a 20by 8.5
thats what i had on my old gtp but i can`t member the offset .

For 18" - 20" wheels offset should be around 40-45mm. My 18" 8.0" width AR Casino wheels are 42mm positive offset.

34mm seems too low to me. The bolt pattern mentioned is OK but used on late model Ford Mustangs and as an alternative on GM/Grand Prixs. Ours is 5X115mm but the 114.3mm will work fine as far as properly bolting on.

Note: The offset may vary depending on the wheel manufacturer. For example some 18" AR wheels are 35mm offset but supposedly will fit. :screwy: Best to try them on to see if they fit properly or check with the supplier or manufacturer before buying.
