Production class

Post by Matt Wills » Mon May 19, 2014 12:26 am

Hi I am looking to enter the production class which I believe is the one where a roll cage is not required?

Are there any modifications allowed or does the car have to be totally standard?

I have studied the blue book online and various other sites and can't seem to get an answer.

Please can anyone help so I can start working towards getting the car ready to compete hopefully later on in the year funds permitting....

Thanks in advance,

Matt.

HI Matt.

you don't need a roll over structure in Standard Car or Road-going Series Production / Road-going Specialist Production classes. You do in Modified Series Production / Modified Specialist Production. Standard Car is an FDMC-defined class and is based on the blue book Road-going classes but with many more restrictions on modifications allowed (aimed very much at standard daily drivers). You are allowed pretty substantial mods under Road-Going (coilovers etc.). In the Modified classes you can really go to town (engine swaps etc.).

It took me a while to get my head around the blue book, but I think I understand it now. I've only done one sprint (Rushmoor last month), and was in a similar position to you six months ago, but if you post up your car's specs and what you are looking to achieve i'll help the best I can.


Dan.

In the acsmc there are some classes not in the blue book. Completely almost std. I think Fdmc run these in their sprints to.

I run my puma in standard road going A2. We are allowed to removed carpets, swap out suspension, tune the engine, and some other Tweeks.

I think suspension and engine are to be unmodified in std classes. Exhaust, wheels, tyres are about the limit.

I run in the MSA blue book definition of A2, not the ACSMC A2, the fact that ACSMC run different class structure to everyone else causes massive confusion at times.

Morning all

Does this mean that I can change from 16 inch wheels to 15's and are race seats allowed? If so do they have to be in date FIA approved ones?

Cheers

Matt.

To avoid any more confusion, let me summarise why A1 and A2 were introduced. I have now been the ACSMC speed co-ordinator for almost 10 years. Some 6 years ago, there was a debate on the use of List 1a verses list 1b tyres, as well as the degree of modifications that could be made and still fit within the 'Roadgoing' category. After many discussions involving competitors from ACSMC, ASEMC and AEMC and their respective co-ordinators, we all agreed on the introduction of a 'standard production' category. The purpose of this category was to allow newcomers to enter the sport and be competitive with minimal modifications. It also offered a lower cost option for regular competitors.The category is a subset of roadgoing and has full MSA approval. 'Performance' modifications are limited, but all 'Safety' (Blue Book S.10..) modifications are allowed. We envisaged that a 'newcomer' may have a car - typically a Saxo VTR/VTS - with perhaps a big bore exhaust, custom wheels etc, who wanted to get more involved.
We have not changed the specifics for some years, and I think it's introduction has been successful. We asked ASWMC at the time if they wanted to be involved/adopt our conclusions. They declined - they believed it (1a or 1b tyres etc) was not an issue in that area.
Hope that helps - 'standard production' is difficult to define in detail, and relies on competitors adopting the spirit of the regulations. See you at Abingdon if anyone wishes to discuss further.

The ACSMC standard classes are really good. I think the level of changes allowed is just right.

Perhaps it is a shame that the lower class capacity limit is different from the one for production classes as that would make it easier to progress. But 1600 is a good limit, prefer that to 1400.
