whats the bolt pattern on my/our cars? im to lazy to look it up right now.

5*115 I think

^ 100% correct! ^

GM 60 degree V6.

And yes, Ford 5x114.3mm wheels fit just fine

Wrong on both counts. We are 90° V6'*, not 60.
Ford pattern will damage your wheels and lugs and could cause a bad thing later on.

nvm

Yep. More than a few people have ran 5x114.3 without any problems.
Off the top of my head, I have, friend w/ a regal does, and I know gameover has too.

And we've had 2 or 3 members that have had rim damage from it. Bottom line is the tapers on the lug holes don't match, and don't distribute the load evenly. It'* a risk. And on any car expected to be 'performance modified', it'* a very bad idea.

The total contact surface area is less than 25% of what it should be, all lugs combined.

But Willren...

I do know the 3800 is a 90 degree V6, but like the 4T60, based on the 440-T4, was made for like the 2.8L, A 60 degree from a Chevy design.

I would ask what came before, but the Buick V6 was around long, long before. Oh I dunno. I'll shut up.

hmm, I thought ours WERE 5x114.3 and NOT 5x115 if you were being more exact.

that was just my thought...but apparently I'm wrong.
