Hi, i have just purchased a sierra 3door replica, it had a big brake conversion done on the front, not very well either! I want 15inch rims so decided to put 2wd discs and 4 pots on. I fitted the 283 disc but the 4 pot does not fit, i was told the hubs are 2wd from previous owner. The hubs do have 12mm threaded holes and abs reluctors inside! I dont understand why they wont fit! About 4mm or so. Any light shed on this would be much appreciated.
Sorry for the drawn out explanation! thanks.

 

kieran 2wd discs are 278mm not 283,they are 4x4 cos

 

Wrong, OP is correct 2WD are 283MM, 4x4 are 278MM!

Are the hubs 2WD Cosworth hubs?

They guy i bought it off said they are 2wd cosworth hubs.

 

Then there is no reason for them not to fit, what is the actual problem?

With disc on, when i offer the caliper in, it just about goes over the hub mount but then goes at an angle,, like either bracket is too thick. Im starting to think they are not cosworth hubs, perhaps standard. Although they do have 12mm holes, which i have read are cosworth...

 

quick edit required lol
