Group 4 Wheel Studs
Benzo - 22/3/13 at 02:54 PM
Hi guys,
Ive had some Alloy hubs made for my TR7 and im using Group 4 studs in them.
I want to do the Rear hubs the same, not alloy but with the grp4 studs.
The front hubs are different where the hub sits infront of the disc much like the cortina setup on the front of the westfield.
On the rear tho the disc sits over the hub, can you drill out the disc to fit over the Grp 4 studs?
Group 4 studs -
I want to be able to have wheels that will go on front and rear.. IE Carry one spare wheel.
Rear Disc Setup similar to my own-

The stud loosely locates the wheel and disc, the hub centre keeps everything true.
It's the friction of the mating surfaces that stops the whole lot spinning, so yes you can drill out.
The torque forces on front wheels and rears are not that dissimilar just one is trying to spin up, the other is slowing down on a RWD car.

Yes but the group 4 stud has a taper on it, and so will then the Group 4 wheels.
If the disc slips over the hub like it does on the rears now, surely the taper will become shorter and will not fill the taper in the inside of the
wheel and therefore will not locate in the same way inside the wheel?

Surely the taper is purely a guide ?
The wheel can't fully engage taper as this would not allow the wheel to locate firmly and truly against the hub drive flange to make a
suraface to surface friction joint.
What style of wheel nut are you using tapered or sleeve ?
On cars of this era the wheel was solely located by the studs and nuts the hub centre spigot was rarely used for centering the wheel.
