I've looked all over for an answer and can't seem to find one anywhere.
I bought a set of staggered rims the front fit perfect, but the rear hit the caliper. The place I bought them from insists it has never been an issue and had no suggestion other than getting spacers.
the rims are 20x10 40mm offset 72.6 CB.
I'm trying to figure out what to do. Do I get spacers, possibly 10mm. Or do I shave the calipers down?
I'm not even sure how I measure to find out what size spacer I need.
before any comments, I'm not going to get rid of the wheels, there is no place where I live that I could have bought them, and the local shops are as clueless as I am.

Can anyone please help?

 

For that type wheel design/style, +40mm offset is too much. It should probably be closer to +30mm. Your offset is bringing the wheel in closer, so that's why it's hitting the caliper. Spacers will push the wheels out so they'll clear the calipers.

 

Offset is not the issue but can become one....

LS rear brakes are not oversized. Funny how some of these places that sell rims have no idea about disk height clearance for BBK brakes, usually fronts are the issue. Maybe they sold you lo disk rear wheels(for more lip). Do not shave calipers. Spacers might work but could create more clearance issues.

Also your center bore is off. We run 60.1 on Toyota Lexus.

 

I have 60.1 to 72.6 hubcentric rings on now, plus I can get custom Bora hubcentric spacers, I have washers on all 5 lugs that clear the calipers so clearance with spacers isn't an issue. So if I need to go with them, how do I know what thickness?
The stacked washers are @10mm. Thick.

 

If I had this issue I would probably measure how much is needed to clear the calipers and then measure the space between the outer most part of the tire sidewall and the inner fender lip to make sure the tire will not contact the fender when the suspension moves the wheel up into the wheel well. Somewhere in between those two measurements should work to clear both the caliper and fender lip. What did the shop suggest in the way of spacer size?

You may have checked it out already, but there is some great info here on wheels/tires: https://www.clublexus.com/forums/ls-...ls-thread.html

 

Something like 80% of the breaking force - probably more - is front brakes.
Just remove the rear brakes - save weight!

 

How's it going, were you able to get the fitment of the wheels taken care of?

 

I just got it done last night. I ordered a pair of 10mm spacers 60.1 to 72.6. With 14mm bolt holes that first perfect. Mounted the wheels drove it around the block a bit, hit a few bumps,

made sure the nuts were tight, and it drives nice and smooth no rubbing and sit nicely in the wheel well.

 

Sweet, the car looks great; I bet you're a happy camper now! Hard to tell from the photo, but it definitely appears that the rear wheel is sitting perfectly tucked in that wheel well. If you haven't done so already, I recommend taking the car on the highway and driving it up to 75-80mph and keeping it at steady speeds, at short intervals, at 60, 65, 70, etc. to check for vibrations.

 

10mm is ok for spacers without bolts (you still lose some thread)... I would take a set with their own studs if 20mm and up... No issues on my corolla running 1inch spacers, non hubcentric, with non hub centric wheels... Think about it, if the hubs did hold stuff together they would show some wear, but they dont. Even oem wheels dont touch the hub, its just there to help center the wheel with the studs... You have to have ACORN lug nuts however, if they're flat, then the wheel might wobble a bit haha

 

I'm glad this thread came along, I'm going to purchase a set of 20" wheels very soon. Hey OP, I assume the rears were the 20 x 10? What width were the front?
