Hi

I have just completed a brake conversion on my 120y and have a question with regards to disc placement.

Instead of having then slip on over the studs which increases track by 8mm is it possible to have them in the factory position.

I can bore out the rotor hub diameter and slide them onto the hub. Can also drill and tap the rotor to bolt factory style and can add a turned up ring behind the rotor if it needs more thickness for the threads.

I guess all you would then do is add spacers behind the caliper bracket to strut face (thickness of hub flange)

Anyone see an issue with this method?

Only issue i see is possibilty of brake mounts to hit strut, will have to measure it before going ahead

Are you having fitment issues due to.the increased track width? The increased track helps the handling.

I have the S13 brake conversion on 120Y struts on my ute. I believe the track increase can be avoided if you use the drum brake stub axle from a 1200.

Your process may work, but seems like a lot of extra machining. Best to not have to alter the rotor in anyway as they are a consumable part and you'll have to replace it as some point. Easier to be able to grab a stock new S13 rotor and throw it on when you need to...but hey if you've got access to a lathe it's up to you.
