Length of shaft, not counting head, approx. 1.95". Threaded portion approx. 1.05"

This is the most common wheel stud used front and rear of all early Classic Mini and Mini Cooper before the change to wide rear drums. These fit most front disk brake cars too, and allow the use of MOST aftermarket wheels when used WITHOUT wheel spacers.
Overall length 1.5" (35mm). Length of shaft, not counting head, 1.375". Threaded portion approx. .875"

For the wider rear drums, see 21A1278.

This is the longest wheel stud available for the Classic Mini- 3.125" (78mm). It should only be used when running 3/4" or larger wheel spacers in special applications. Note that these will NOT fit most front disk brake cars and are intended primarily for use on the rear with wide rear drums AND wheel spacers.
3.125" is length of shaft, not including the head. Threaded portion approx. 1.125"

All wheel studs used on the Mini are 3/8" diameter with 24 Thread per inch.

7/16-20 UNF stud in a three inch length for competition applications. The shaft is threaded all the way so can be trimmed for a perfect fit for your wheel and/or spacer combination. Will require machining the hubs & drive flanges, and possibly the wheels, but will provide the ultimate stregth for all out competion, or your turbo VTEC!

Lenght of shaft, not counting the head, 2.875". Lenght of threaded portion approx. 2.125"

These were the stock rear wheel studs for 90s cars with the "Sportspac" option 6X13" wheels, but they can be fitted to ANY Classic Mini as needed to allow for wide rear drums, custom wheels and/or wheel spacers.
These have a shank length of 2 3/8" (58mm) and about 1 1/8" (28mm) of thread so are just about 1/8" longer than the standard rear Cooper S 21A1278.
All wheel studs used on the Mini are 3/8" diameter with 24 Thread per inch.

 

This is the correct length (55mm) for all Classic Minis using the rear spacered type drum as fitted to all Cooper "S", 1275GT and every mini from 1984 to 1996 except the ERA Turbo and Sports Pack cars (which had 13" wheels)
Length of shaft, not counting head, 2.25". Length of threaded portion, approx. .875"
Stanfard front wheel stud for Minis with 8.4" disc brakes when Rover changed over to 12" steel wheels in 1984. These are the shortest wheel studs available at 1.45 inches (37mm) total length including head, so make sure they're long enough if you have aftermarket oversize wheels. Length not counting head is 1.25" (31.8mm).
This Classic Mini Wheel stud is about 1/2" longer than standard. It provides a bit of extra safety when switching to alloy wheels to allow for the thicker wheel flange compared to steel wheels. This is also the one to use if adding wheel spacers up to 1/2 inch thick.

Question:
I just ordered and installed these studs on my '89. After installing one stud I noticed the rotor cracked. (I was using the correct tooling and applied very little pressure.) The stud diameter is correct but it's designed for a countersunk hole where the originals have a flat face. No doubt the others would crack as well, especially after torquing the wheels on and driving. I believe these studs are actually for later model Rover vehicles with countersunk holes. Do you have the correct studs for the Mini?
Answer:
We offer several wheel studs for different applications - make sure the one you select is the right length/type for your car - standard wheel studs for drum and most disc brake cars with standard wheels is part number 21A2064 - larger disc brake cars like the rovor mini used a longer stud which is NAM5645

hope this helps
