will thw rim fit?

I seen some 18" focal matte black rims 5x114.3. Will they fit on my 2000 galant ?

Will if fit? Yes, correct bolt pattern. For Fitment issues, I cannot say lol

They will fit, but you might need to roll the fenders to avoid any scrubbing.

There is a whole stickied thread in the suspension, brakes, wheels and tires section on this man. Please search before posting as there have been many different wheel tire set ups documented over the years, and I bet the wheel fitment guide has all the specs you'll need to make sure they will fit.
