As the title states, I'd be very appreciative if anybody had any links or info associated with it. I can get two rotors for $35 shipped, but I have no idea what calipers, if "bunny ears" are needed to hold the caliper, any line adjustments, etc. THANK YOU!!!


*Yes, I know the 5x130 conversion is easier, I want to keep my 8.9lb. Panasports instead of updating.

Hi guys. I did this many years ago and was very happy with them.

You need 405 rear rotors and 405 rear calipers. The 924 handbrake cables work without modification (think I re-routed them under the torsion beam instead of above or something). The bracket to mount the calipers needs to be made. I used a piece of 5 or 6mm thick steel sheet and cut it to size and drilled the relevant holes. You remove the drum, remove the 4 bolts that hold bearing cap in place, remove the drum backplate and use that as a template for the caliper bracket. The bracket replaces the back plate. You then need to attack the drum with an angle grinder to reduce its size before putting it in the lathe and turning it down so the 405 disc will fit over it. I.e. You convert the drum into a hub to mount the disc. Then you just need to make a couple of hard brake lines to go to the calipers and you're done. Sounds more complicated than it is!
