i have 17x9 cobra wheels on my t-bird right now running 275 out back with the offset at 36, will these go right on a ls without issues? thanks.

Nah they'll rub, too little offset.

Also wrong bolt pattern! to low of an offset

Also wrong bolt pattern!

That depends on what year thunderbird we are talking about.

the t-bird is a 97, will they fit on a mark 8? thanks.

I put on my cousin's aftermarket 18" wheels from his 96 t-bird on my LS. Not sure about the offset but they stuck out too much.

+1 on the sticking out. Mine are 17x7.5 on a 42mm offset and they almost stick out. Your looking at a wider wheel and less offset.

It was 9" wide and I found a pic of it (click on the image to go my gallery and view full size 2MP image):

Yeah, if they fit that vintage T-Bird, they should fit both an LS and a Mark VIII, bolt-pattern wise. I don't know what the Mark's offset is, but it should be the same as or very close to the T-Bird's. (The LS's is 60mm, BTW.)

I had a MarkVIII with Cobra R's that I had on my 95 Cougar, they'll fit with no issues. The LS shares the same bolt pattern with 93-98 Lincoln Mark VIII's and with the 89-97 T-bird/Cougar MN-12's also with the Rangers and Marquis and Crown Vics and Marauders I believe. The offset is different though. And you dont want to go with 9" wide b/c to me they'll stick out to much.

Not Rangers, they are 5 on 4.5 like a Mustang. IIRC Panthers share the F-150 5 on 5.5 pattern.


Remember this formula

[.5(x)]-y=how far it will stick out where x is the width of the wheel and y is the back spacing.

if x is 9" then half would be 4.5"
if y is 36mm or 1.41" http://www.psinvention.com/zoetic/convert.htm
the outer edge of your wheel will be 3.09" out from the face of your hub. Don't forget also to allow up to 3/8" for tire bulge because tires are almost never flush with the edge of the rim.

I have a 7.5 wheel with 42mm bs and they don't stick out at all, but I have noticed more road splash on the body panels because they do stick out at the bottom more.
