ok guys i would like to know if some 18's would fit nicely without having to make any camber corrections. i know the msp already has 215/45/17 and i figure if i went with 18's i would be at 215/40/18, and from this tire calculator i used it says when im driving 60mph im actually going 60.4 so its not perfect but its not way off. The rims i looking at getting are 18x8 is the width going to be a problem?
 
I wouldn't go with anything wider than 7.5" unless you plan on modifying your fenders. Also pay close attention to the offest.
 
I have 18x7.5 with 215/40/18's lowered on Teins. No problems. I don't know about 18x8's That might be cutting it close. What is the offset? If it +45 you should be ok. Under that I don't know, you might rub inside.
 
the 42 offset probably won't be enough with a 7.5 and 215/40
 
this line is key "If the offset were to stay the same while you added width, the additional width would be split evenly between the inside and outside."

you'd be fine with a +42mm offset if the wheel were 7" wide, but when you add .5", that gets added to each side (6.35 mm to each side)

ok so am i wrong to beleave that these *should* fit with out a problem?
yes, although it may be close

if you're really sold on those rims, get 215/35s and pray

and if all else fails you may need to yank on the rear fenders a bit or have the mounting surface of the rims machined a couple mm's
 
ok from what the calculator says

The clearance from stut housing to the inside of the wheel will be 3mm MORE
The outside edge of the wheel will EXTEND an extra 3mm

i guess that aint too bad
 
that cannot be right

hang on while I calculate this ;)
 
did you input stock MSP rims? 17x7, 50 mm

going to a 18x7.5, 42 mm

you would be adding 6.35 mm to each side and pushing the rim out 8 mm

so you'd be 1.65 mm farther away from the strut housing, but 14.35 mm further out than stock
