S60s Regulations

We hope you are enjoying your time in the workshop, as you prepare the car for the rapidly approaching new season? To avoid disappointment at a race meeting, please can we ask you to have a read through the draft regulations for this year, drawing particular attention to two areas, tyres and appearance. It's the driver's responsibility to ensure compliance. We are a friendly series, but a fair one, so please accept this as fair warning.

Tyres The 2026 tyre list has been updated, after close consultation with series sponsor, Adams & Page and Yokohama. Stocks have been secured and reserved for you of suitable tyres for the coming season. On the odd occasion Yokohama 60 profile sizes have become unavailable, a specific alternative has been listed (Adams & Page may stock these). 'If you choose to run a non-production size wheel diameter, it must run within the confines of the standard bodyshell and be a 60 profile tyre. If a 60 profile tyre is not available in that size you must run the standard sized wheel diameter.'

Appearance A. As our longest running series our silhouette and appearance regulations have been pretty consistent over the decades. Last season one or two drivers appear to have been having fun with a hole-saw!

Our regulations are brief, but state : The original silhouette/appearance is to be retained from all angles....

For further confirmation that holes are not permitted, Motorsport UK NCR Ch. 7, Ap. 2.7 says: ' As a general principal of all Technical Regulations it is prohibited to carry out any tuning or modification unless expressly permitted by the relevant Regulation(s) or a component is stated to be ‘free’.'

If you have already cut holes or vents please can we ask they are neatly covered in tape or vinyl in the short term and ultimately replace the panel in time. Alternatively, if you want to further modify your car, you would be welcomed within the R-Werks Special Saloons & Modsports Series. A further reminder about no aero aids, such as air dams, splitters, spoilers etc - there have been a number of Triumph TRs with front air dams in particular - 'they raced like that in period....' unless factory fitted to road-going, showroom cars these are not allowed.

B. We are aware of tyres that are starting to poke outside of the bodywork. This raises safety concerns (increases the chance of becoming airborne), appearance and compliance. The relevant part of NCR Ch.7 Ap.2 6.9. says: ..... be equipped on all wheels with mudguards which present no sharp edges and cover the complete wheel (flange+rim+tyre) around an arc of 120 degrees. This minimum coverage must:

a. be achieved with a continuous surface of rigid material...... The tyre must not be visible when viewed from above. When viewed from the rear the tyre must not be visible above any point 50mm or more above the axle centre line.

Making the arches wider is not permitted within our series, so running a specifically listed, smaller width tyre and/or wheel width and offset is the answer. If that means you have less grip than before, so be it, it's the same rule for all.

If in doubt please contact us, using our emails on the series page: https://www.classicsportscarclub.co.uk/swinging-sixties

There, that's the heavy stuff dealt with, let's get back to having fun tinkering in the garage for another month or two.

Best regards, Malcolm and Ian.
