Ok im going to fix the steelies up a little bit. So i know for the trim rings i need 15" 1 3/4" depth but does brand matter? Do the ebay ones have to same clip setup as some good ones? Also does anywhere make some caps to cover up just the center of the rim where the lugs are? I cant post links but these are what im talking about

Then the last question is how much spacing does the rear stockers need to line up with the front?I seen the post on this page about using older celica caps but they seem pretty hard to find

O.K. Turbo....

The trim rings I have seen all have a simalar set up as the OEM hubcaps.
They stay on. Some say stainless steel is better, read this thread:

Center CAP from NAPA:
There is a hub cover / grease cap that fits on the XB's stock 15 inch rims.
Go to NAPA, in their Balkamp catalog, #730-2411 as seen here:

This fits over the center hole lip, so it can be removed without removing the wheel.
I keep mine on with the trim rings and with hubcaps.

Please note TURBO: I tried Hubcap Mike's 'Smoothie' hubcaps but they don't fit XB's OEM wheels. Mike gave me an exchange and I got the racing disks. Talk to Mike before you buy, he has an XB and could use his box as a test fit before a purchase.

The rear wheels are 1 inch closer to each other than the front wheels.
If you install 1/2 inch spacers on both rear hubs, your rear wheels will be exactly behind your front wheels. Search for XB REAR SPACERS for many threads to read about installation and vendors.
