caprisport hub diameter?

[vibrating_Cake]

Does anyone happen to know the diameter you need to machine the hubs down for the caprisport 280 kit, running the 283mm Sierra RS cosworth front disks??

and does anyone know if it needs to be a tight or loose fit??

 

also, if you guys dont know this info, does anyone with this conversion have any discs hanging around and able to measure me a dimension?

I had a hub machined before but its always been "slighlty" wonky, (left to right) so my car tends to eat steering racks, which lead me to the question, does the OD of the hub need to be a tight fit into the ID of the disk?

 

We think the hub was machined on a rugby ball shaped machine (very very slightly) so it does affect it slightly, can feel it~45mph. but dont have the disks off the car to change stuff over.

 

 

The dimension i need is the internal diameter of the offset step of the disc, not the central bore (63mm) the "inner diameter of the tunnel in the middle of the disc" lol.

 

Ta very much!!!

That shouldn't make a difference. If the disc is centred on the hub the wheel and wheel bolts will hold it in place. The hub may not be flat causing run out
