How to 5 Lug Swap an S13 and Keep ABS

[allntrlundrgrnd]

I imported a relatively unmolestered 180sx Type-X equipped with ABS last year and wanted to put R33 GTR wheels on it. Given the cars relatively original condition and me slowly becoming a boomer, I scoured the internet for a definitive answer and never really found a 100% confirmation how to do it. So, here it is for the 3 people who don't want to delete their factory ABS system. I am keeping stock brakes for now.

Rears are easy, I just swapped on some Z32 NA rear hubs, which are a bolt on replacement. You must use hubs from an NA car because turbo axle splines are apparently bigger and don't fit. Buy S14 rear 5 lug rotors.

For the front I ordered GKtech 5 lug conversion hubs and swapped the ABS ring from my 4 lug hubs onto the gktech hubs.

Grab a suitable instrument of your choosing to CAREFULLY tap the ring and slowly work your way around until it separates from the 4 lug hub. I soaked the ABS ring in PB blaster overnight and it came off relatively easily, just take your time because if you break the ring they are discontinued and you'll have to find some used ABS hubs. I did have to use a dremel to remove the paint on the GKtech hubs in order to be able to press on the ABS ring.

You'll have to press in front wheel bearings, I used NSK Wheel Bearing 30BWD04 which are made in japan and seem to be good quality, I could not find OEM that were not absurdly priced. More bearing options can be found here: https://blog.gktech.com/blog/nissan-...-part-numbers/

Front rotors I used Brembo 09525410 which is the part number for 1995 Maxima, they are 280mm x 22mm ~$50 each from rockauto.

There's some measurements in the pictures, I could not find an interchangeable nissan part with the same tooth count or diameter.
