what spacers do I need to mount 17x9s?

Hello, I wish to mount 17x9s to an 86 Cougar 5.0 and plan to use 245/55 tires.  What size spacers will I need and do I need new lugs? Can anyone recommend a vendor for the spacers?  Thanks.

Everything depends on the backspacing of your wheels and your brake setup.

Here's some detail on the wheels:  (17x9" 2006 2007SHELBY COBRA / GT-500 style GT500 chrome aluminum wheels, in Ford's 4x4.25" lug pattern, +18mm offset).  Everything on the Cougar is stock.  Does that help?

Then they will work just fine.  Fit will be just about the same.

I don't know about 245/55 I would go with something with less sidewall like a 245/45. Maybe wider in the back. Those GT500 wheels will look awsome I bet. Does anyone have a picture with these on a fox T-bird?

I got some cheap spacers from JCWhitney that are 1/8" thick and I have two on each front wheel. I wish I could have avoided using that much spacer, hopefully the TC spindles will help somehow.
These are the wheels I have:

Did you have to install longer lug bolts?

Thanks everyone for the feedback.  Is the 245/45 a personnal preferance or do you think there might be clearance issues with the 245/55?

Here they are on a Cougar (like this guy has).  Probably pretty similar on a Tbird.  ;)

No, I was afraid I might have to, but nope.

I'm not sure but a 55 might be close to the fender lip on the front, the 255/40s on mine at stock ride height could likely hit if there was a big enough bump in the road. The rear shouldn't be a problem.
