18'' Wheels on your A? What size tires are you running? Post Pics!

18s in the sig.

What size tires are you running?
Any suspension/body modifications to make them fit?
Just curious, very nice car!

4.5" = 114.3mm. Exactly. That is the conversion, no rounding, feel free to try it yourself.

1"=25.4 mm. 4.5 x 25.4 = 114.3

Any wheel advertised as 5x114.3 will fit the bolt pattern for LBP mopars.

5x115mm will not unless you open up the bolt holes, I wouldn't do it myself, but I'm sure its been done.

No need to open up the bolt holes on a 5x115 rim. The bolt pattern is .7mm off, they fit perfectly fine, without any issues at all. I've got a set of 5x115 rims on my 2002 Intrepid with no problems. Like I said, I've put over 14k miles on the car since I bought the rims, including several high speed runs, and I've had no issues whatsoever. Here is the car, with its 5x115 rims on its 5x114.3 hubs:
