hi all

can anyone tell me whats the story with re-drilling hubs.

ive got my escort hubs (4stud) and i want to use falcon discs (5stud).aswell as running 5 stud allround

now if the hub was blank i.e no holes i wouldnt have a problem drilling them but the problem i have is

one hole is in the wrong place and from my understanding plug welding the a cast hub is a no no.

so what are mu options here?

As you say welding the holes is a no no on stressed cast front hubs.

This method has been used on the rear axles for years as in most cases they are billet so that's the back sorted with a disc conversion from a Sierra Sapphire or Cosworth, If you want to keep it on 13" wheels you might have to use something else though. (Mitsi Gallant)?

The MK4 Zephyr/Zodiac conversion works on the front but the offset means you can only run solid rotors which means you get the 5 stud but no real improvement in breaking.

Another option is to get billet hubs made up to suit the Falcon vented or other suitable vented rotor offset turned down to the same diameter as the original rotors and the 5 stud PCD patten with 4 pot Austin Princess calipers (same bolt up and reach as the Escort strut) with alloy spacers between the two halves to make it suit the thicker vented rotor, I've used this option my self years ago for a MK1 Escort running a Supercharged 3.0 V6 and it's not as expensive as you might imagine.

Some one on this site must know a good fitter that can spin you up some hubs, shave down the rotors and cut some spacers for the calipers.

The beauty of this method is that it looks stock as you can still use the stock Escort caliper mounts, dust shield and Early Zephyr/Zodiac steels to keep it on 13" Wheels with hubcaps.

Should be certified however.

The Princess calipers are still available as NOS from England or try Iona Motors in New Plymouth.

This conversion is has been used so much there that high temp pads are available if you want to go racing and need longer life pads.

I hope this helps.

good information thanks mate but keeping it on 13s wasnt going to happen its been set up to run 17x9s allround and 17x10 if needed on the rear.

ive found a set of trailer hubs that fit the escort stub axle and are 5stud with close offset and the 296mm falcon disc will bolt on the front between hub and rim and then ill just make mounts for nissan 4 pots.

cheers again
