The holes in the discs are only slightly larger than the axle/pin to run thru. The brakes are glued to the outer part of the bearing housing. The wheels fit right into the little cup on the discs. I tighten the wheels and lugnuts not quite completely tight, but enough that there is no wobble. The brakes stay in place when the axles and wheels spin.

You have to use the "shallow" discs from the XS Tuning Kit, and shave the backside of the discs flat. Then drill out the centers slightly larger than the axle/pins.

so you cant change the bushing/bearings? hmm

Not without removing the brakes. I did this car mainly for show, and it already has the bearings installed. It will only be driven on the kitchen floor, so it probably will never need new bearings. I wouldn't install the brakes on my racer.

sory to get off the topic but, what does btw mean?

:bled: :btc: bg395 bbcelbl bbgtr brspec bbsups

BC EDIT: Removed innapropriate language and replaced with something more sutable.

Thanks for the compliments! Let's remember though this is a public forum, so please try to watch the language.

here's an idea...
 

I made the hole in the center of my brakes large enough to go OVER the bearing hub...and glued them to the outside of it...allowing bearing removal and not spacing the wheels out at all!!! you should try it...lot better!

Disc Brakes Mod
 

Howdy,
I also did a brake rotor mod to my Skyline. I used sheet lexan to make them out of. I traced the outline of a AA batt to get the right size. I'm not totally done with them yet. I only have two made at this time but am going to remake some new ones with calipers. Just made these ones really quickly the other night. Here are a few pics.

They are a little hard to see but they are there. I will post other pics when I get the new ones done. You can see more pics on my site and my forum. Later

yo sup im not quite following bc i have no idea of the meaning backside

ok the brake pads look all tight and all but what kind of screw did u put on it doesnt look like the standard one that comes with the car

i don't think they're supposed to look like stock disc brakes.

no im not talking about the disc brake im talking about the screw that holds the wheels on

They are aluminum wheelnuts made for the RS4 and Mini Z's.
