Notes
WarrantyChrome: two year structural and cosmetic
Painted: two year structural and one year cosmetic

The warranty period commences from the date of invoice and is subject to the wheels being maintained as per our Wheel Care advice and in conjunction with our Terms and Conditions. Please retain the warranty tag supplied with each wheel as it contains the information required to identify the wheel in the event of a claim.

Please note: MWS warranty automatically becomes void if the wheels have been: subject to re-work or change; fitted with tyres other than the manufacturer’s recommended fitment; or used for track events.
Splined Hubs
Option 1RSK067 - Front Left
RSK066 - Front Right

Integral fitting hubs so no nuts necessary

Click here for a guide to fitting hubs, caps and centre-lock wire wheels
Option 2RSMGB3RL - Rear Left
RSMGB3RR - Rear Right

Four RN12-MGB3 nuts per hub are required plus a spare.

Studs must be shortened otherwise they will foul the back of the wheel.

The recommended method of doing this is:
remove steel wheel
slide hub onto studs
screw the spare nut down into place on one of the studs
cut the stud back
remove the nut and repeat until all studs have been shortened
fit the hubs using the other nuts
The reason for this is that very often when cutting back the studs the nut will get damaged.

Bolt-on splines, unless fitted as original equipment, will increase the track by up to 1¼" per wheel

Studs will require shortening, click here for a diagram

Option 31962 - 1964 models originally required 12 TPI adapters (drilled for 9/16 studs). However, this option has never been offered by MWS. The 8 TPI bolt-on adapters can also be fitted without any problems.
