I am about to do a 5 stud conversion to my Cefiro and this is what I know so far:
- The S13 and S14 front hubs have a different bore size, and therefore you cannot just bolt the S14 hub onto the S13 front carrier.
- The S13 and S14 have different sized wheel bearings, which make the above not possible
- You can buy 5 stud hubs that are made to fit the S13 bearing, meaning converting the front is rather easy. It is advised at this time to replace the front bearings. These will need to be pressed in and may cost you upto $200 to do
- The other alternative is to replace the front hub, carrier, ball joint and lower arm with that off a S14. Then there is no messy takings apart of the hub
- The R32 hub, carrier, ball joint and lower arm are the easist way to upgrade the rear. This will allow you to run the bigger brakes also.
If you choose to upgrade front and rear calipers also you will need to replace your front Brake Master Cylinder with a bigger item. A BM44 will do the job. The Standard cylinder wont allow enough fluid to be pumped.
