20x9.5 45mm on H&R SuperSports

Guys Im having a hell of a time picking out some new wheels that will work with the newly installed supersport springs

I finally found a set I like that dont cost a fortune.

setup would be
20x8.5 45mm
20x9.5 45mm

Would this work with any tire or will it end up rubbing

Sidenote, I've already had 19" wheels and they just didn't do it for me, so that size is not an option. Thanks.

You should clear no problem as long as you use a narrow tire that doesn't bulge past the lip of the wheels. Those are the width and offsets I'm running but in 19's

What size tires do you run, I need the same overall diamater and width

I'm thinking

235/30/20
265/25/20 or 275/25/20

Does anyone have any input, would be greatly appreciated

There is also the option of running 20x8.5 45mm all the way around if the 9.5 @ 45mm will not work, I would just like to run a wider wheel/tire in the back if possible

265/25/20. You should be fine with that without any major fender work

Anything wider than a 9.5 combined with an offset lower than 42 you might need to fold or shave your fenders.

You will NOT clear out back, u need 50mm to do so in an average 265/25/20 setup. It is a rare tire, 2 brands only and super expensive. I dont get the whole 19s dont do it, on SS they are perfect fit, but its your car. Anyway you will need 255/25/20 in nittos, thats the only choice w that offset, 225/30/20 up front to match............

where do you live? I'd be so scared to run on 25, especially on hres. wouldn't wanna bend them (so expensive). I'll ask rob for you later today, he ran klassen 20's on 35 or 30 (pretty sure it was 35)

pretty sure he used hankook for tires too.

Or you can go 235/35/20 front and 275/30/20 rear... more selection from those specs

You might be able to pull it off with a 275/30/20 tire... worse comes to worst you may need a slight fender roll or shaving.
