Offsets on a SC430

Right now have
19x9 +19 and 19x10 +19

but I'm looking at
19x9 +15 and 19x10 +5

Offset calculator says they will poke out 4mm & 14mm more respectively (shouldn't be a problem)
but inner clearance between inside of the wheel and strut housing will be 4mm & 14mm more respectively.

Anyone know if these new ones will fit, or how I can measure it myself?

Thanks
Stefan

4mm is a little bit less than 1/4 inch. 14mm is a little bit more than 1/2 inch. Do you have 1/4 inch of space between your front fender and the wheel? Do you have 1/2 inch of space between your rear fender and the wheel? If yes, go for it. If no, you'd have to camber the wheels a tad or pull the fenders.

inner clearance is not the concern here, it's the outer. if you say adding 4mm/14mm "shouldn't be a problem" then it will fit!
