Yeah 19's will fit on a Cougar/Contour but do require a coil over conversion to get rid of the bulky stock spring perch and you must do a 40mm offset on the wheel

I am running Axis Se7en's 19x8 235/35 Nitto 555 Extreme Rubber

I have coil overs on my gf's Contour and have 18x7.5 Alba Blazes on it. Hopefully next spring we will be adding a set of 19's to it, if she has the under hood stuff done.... psssssssssstttt wink
