Will this fit on my xB? I have found a really good deal and am wondering. I'm most likely either going to get the spy springs or the tanabe ones. Will this set-up fit? Any help is appreciated...thanks!

man,you guys need to learn the search feature for common questions like these - it's really easy :)

but here's your answer:

anything over +42mm and 7.5" in width will need at least a 5mm spacer in the rear, and you may have to shear a bolt on the rear suspension arm to get enough clearance.

Brian,

Thanks for the help... I tried searching but didn't really find anything specific to my scenario... but i'll remember that next time :)

what does 44 offset mean? will it sit closer to the inside of the car or stick out more? Also, what about the front? will it fit ok?

hope this helps

Thanks man...

So you guys think I should do it?

$500 18" x 7.5 RH C5 with decent tires
4x 100 offset 44

im running 18x7.5 with 45mm offset....i ran the tires without spacers for over 1k....now i have 15mm h&r spacers rear....
if u get the tires i would recommend the spacers....just for the rear tires....the fronts should be fine....mine dont rub at all....

if you dont mind me asking...how come you ran it without spacers for so long? What would happen if you didn't? Did you have to cut some bolt in the rear? Thanks for the help... I think I'm gonna get those wheels now.

i didnt have any problems without the spacers...just didnt look right....the back need to sit out further to be even with the front...didnt cut any bolt in the rear....

certain wheels are different.. offset matters
but the way the rim/spokes are matters as well..

like some rims(usually those jdm expensive ones) have u select the
DISC type.. like for cars with bigger brakes that need clearance or what not.
i remember when we tried to put a certain wheel on my friends xb..
the spokes in front wouldn't clear the caliper.. even though it was like around 44 offset.
on a 7.5 in rim..

double check.. call up a dealer of RH or check online..
tell them the car u want. pretend u wanna buy a set from them..
tell them u have a scion whatever.. and will 18x7.5 +44 FROM THIS company fit
