To add 20mm wheel spacers...

NE1 exchange the existing wheel studs for longer ones for the rear?
How difficult was it?

Minsk99 did a tutorial on how to install H&R extended studs in the tech section (http://www.scionlife.com/tech).

If you're just spacing out the back, I'd suggest ScionVan's 10mm wheel shims which go behind the hub. Then a 10mm spacer (which Van sells, as well). He sells both on his site, www.onetongarage.com.

Thanks that's helpful but I'll be changing the rear and rear setup looks different from front....

I suggest you get Van's 10mm wheel shims and 10mm wheel spacers...

Van's 10mm wheel spacers are not hub centric.....our cars need hub centric spacers that come with longer bolts. There's no instructions for this on his website..

I already have Van's shim kit installed.

damn, a whole 30mm space? Maybe you should've gotten a better fitting wheel offset... :P

Unfortunately, that's what's required to completely fill the rear fenders on our xAs....
Without it, even with max wheel offset, back of our cars can look like a small version of Toyota family van....
