Race series allowing Grp 2 arches?

[Brynmor]

We’re mid way through building the mk1 as a multi discipline car and as some of you know she has Grp 2 arches really neatly fitted. In Historic Rallying etc they’re perfectly allowed but I notice things like hscc no one has them? Is there an historic race series where you can run them ?

Cheers and Happy New Year

The CSCC swinging sixties regulations forbid any changes to silhouette from front, rear, side etc but loads of people seam to run them. There’s also mk3-5 in there too, go figure.

CSCC have special regs for Minis which does allow the fitting of arches.

Swinging Sixties Race Series Reference sheet for Mini competitors

Mini Bodyshell. As already stated, the car must maintain its original silhouette in all planes. The only exception here is the addition of wheel arch extensions. The series Committee have been generous in allowing the Mini runners to fit arch extensions, the only marque racing that is allowed them. This is because practically every wheel rim and stipulated regulation tyre combination will not fit under the standard wheel arch profile on the Mini. However, there are limitations as to the arch extensions that are deemed acceptable, bearing in mind the 'Swinging Sixties' title and the fact that we do not want to be seen to be abusing this facility extended to us. Whilst most narrow width arch extensions are likely to be acceptable, there are only two styles of wider arch extensions that will be allowed. Since there is some disagreement as to just what the arch styles are called (group 2, group 4, group 5 etc.) the pictures detailed below show what is acceptable. Width should be kept to a minimum for legality only (must cover the tyre in plan view). No ludicrous 'Carlos Fandango' versions will be allowed, such as those used by Mini Miglia racers. Clubman bodyshells are acceptable since the Clubman was first produced and sold in 1969.

Is it only UK cars allowed? Oz Ss came from the Factory with what I think you would call Gp 2 arches fitted.

That’s great many thanks, really not wild on taking them off but we’ll see

HSCC is pre 66 so the arches are not period correct for a touring car, same for pre 66 appendix k, they’re not homologated for a touring car.

Both CSCC Swinging 60s and CTCRC allow arches and neither require CR65s .
