| Warranty | Stainless Steel and Chrome: 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 1 | Bolt-on splined hubs - recommended option for conversion from steel wheels to wire wheels - you will need to check the clearance on the front brake pipes : RSK193 - Left (fixing nuts supplied) RSK192 - Right (fixing nuts supplied) The first time you fit bolt-on hubs it is recommended that customers purchase an additional spare nylock nut to use as a cutting guide. When fitting : place the bolt-on hub onto the studs and screw on the spare nut; cut the stud down; remove the spare nut; apply the spare nut to the next stud and repeat. When all the studs have been cut down to the right size fit the hubs using all new nuts and dispose of the spare nut. This advice applies to the nylock nuts but not the standard nuts because of the safety implications of any damage to the nylon inner. If you have to remove the nuts for any reason in the future then as long as the nylon inner is undamaged they can theoretically be refitted but for safety's sake we would recommend they are replaced. Replacement fixing nuts (RN38NYLOCK) are available OR RSK373 - Left RSK372 - Right Four RN38 per hub 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 Click here for a guide to fitting hubs, caps and centre-lock wire wheels | ||
| Option 2 | Integral splined hubs - if converting from steel wheels to wire wheels this option requires extensive modification - half shafts have to be replaced at the rear and the steel wheel brake discs replaced by wire wheel brake discs : RSK111 - Front Left for Disc Brakes RSK110 - Front Right for Disc Brakes RSK109 - Rear Left RSK108 - Rear Right These integral splined hubs are 8 TPI, however, Midget Mk I (GAN1+2) may have 12 TPI splined hubs; these are available to special order. Integral fitting hubs so no nuts necessary Click here for a guide to fitting hubs, caps and centre-lock wire wheels | ||

| Extra Information | |||
| Other comments | A small number (around 20 cars) were manufactured in 1962 with wider rear axles. Slight modifications may be required for "Square Wheel Arches", axle may sit further to left/right. Always check the history of the vehicle to ensure that there have been no modifications to the running gear. Hubs/splines, spinners and nuts remain the same, unless noted otherwise, regardless of which wheel is fitted. We also stock wire wheel maintenance accessories such as our Cleaning Kit (Refills available), Cleaning Brush, Degreaser and Tyre Foam.
