But what about mounting the callipers??? To change from a drum rear to disk would involve more i'm sure, and the stud pattern would need to be changed on the axle, how strong are the gemi diffs, i'm talking a 13b rotary, will it handle it??? I've found a brake kit for the front 300mm VX rotor and twin spot callipers, dunno if i'll need to do the rear, but what i'm really askin is whether the diff and complete other stuff would be a better idea than modifying the standard diff if it aint gonna hold up in the end... |

The disk conversion for the fron you've got two options in kits that i could find anyway, apart from piazza disks which are near impossible to find. One is the castlemaine rod shop in VIC web address http://www.rodshop.com.au, or Hoppers stoppers also in VIC web address http://www.hoppers.com.au, they both mail them out. The castlemaine rod shop kit is $275 i think, for basically the mounting brackets and you will have to source HQ/WB callipers and XW/XY disks, and you're left with a ford stud pattern, but this isnt quite as big or cheap as the Hoppers stoppers kit which comes with the 300mm rotors and twin spot callipers from a VX commodore and everything else bar a master cylinder, its around $690 to $950 depending on what rotor you want eg slotted etc. Its so cheap as he gets the parts from HSV when the brakes are upgraded from factory, 50km on em or so. Which engines the 4ze1??? Can anyone help me bout the whole diff thing??? Hope that helps ya mate... |

Fitting Commodore discs will NOT change the stud pattern. You will need to change the axles this is where the wheel studs are mounted.I have heard that you can get commodore axles shortened and resplined. I have about 200hp in my Gemini race car and the diff handles that ok but it will depend on how much you abuse it.I have seen a Hilux diff conversion with no torque tube and you will need a new tail shaft anyway. McDonald bros Drag racing in Thomastown sell this type of setup I have seen a rotor gem there with this diff. Good luck
