2010 Rule Changes
Confirmed rule changes for Season 2010.

1. CARS & BODIES

The car bodywork rulings for 2010, as noted in 2009 rules, will be implemented i.e. original boot, bonnet, tops of wings, tops of doors, roof, etc, from 150mm below lower window aperture and upwards. You may combine original wing tops and bonnet to ahieve a full width bonnet. The B pillar must be retained, and be in its original position - you may not move the b pillar, to increase window apertures.

A maximum weight of 1300kg will be introduced.

The car (excluding driver) will be required AT ANY TIME to record a maximum inside weight of 55%. The car must be race ready when this is recorded.

The body shell must be symmetrical on both sides, with the required door/sill/window heights to be achieved on both sides of the car. Sills folded under the car to achieve correct bodyshell heights are not permitted, and therefore the sill must be backed by steelwork, tube or shs at its lowest point.

3. SUSPENSION

All cars must achieve a minimum ground clearance, between the front and rear wheels, of 75mm. This will be checked by rolling a pipe under the car from front wheels to rear wheels.

Each car will be permitted one standard strut/shock absorber, for each wheel/corner of the car. No extra shock absorbers permitted EXCEPT THE Avo F2 style shock absorber to be retained on the near side front.

WHEELBASE

Outside lead of 2" only permitted. The maximum camber permitted on the passenger side front wheel is 15 degrees. Camber on the rear wheels must be the same on both sides.

FRONT

Front struts must be mounted in original position - both front struts must be mounted symetrically across the front axle. Front strut tops may be adjusted in and out to achieve camber, but not backwards or forwards. Lower arms must also be mounted in their original position, and must be mounted symetrically on each side, and must be the same height from the ground on both sides of the car, when the car is level.

Retaining lug must not be removed on front struts - ensuring that the strut is mounted in its original position.

REAR

No multi hole adjustment permitted on rear wishbone mountings. Rear wishbone mountings must be the same height from the ground on both sides of the car, when the car is level.

11. TYRES

The Avon 7.3 tyre will remain as the principal tyre for 2010, but there will be a complete ban on tyre softener from 1 January 2010 and no Avon Slick Tyres permitted for use after 1 May 2010.

The Saloon Stock Car Association are still currently testing tyres with a view to additional tyre options for 2010, and a possible tyre change for 2011.

The Yokohama A048 will not be acceptable as a "starter" tyre for White/Yellow grade drivers.

16. FUEL SYSTEM

All fuel lines must be clipped securely, and routed away from electrics.

The fuel tank, with a maximum 2 gallon capacity, is to be positioned along the centre line of the car, and on top of the chassis, in the rear seat/boot area.

The fitting of a non-return valve will be compulsory.

There you go.More questions than answers and better defintions would be nice!

So how many cars will need modifying to meet these new rules? All of them?

I don't know anything about the construction of saloons, but how much work is going to be involved to incorporate all these changes? Would it be easier to just build a new car?

basically it requires all the cars which race tarmac to be scrapped and start again,it is easier than a rebuild and the way the economy is people dont have much spare cash to build a new car even though there old one is still ok, even the shale cars require major work to be ok in the new rules, think cabs is right about the rules of the spedeworth cars
as i have already said if the car of eddy darby had been banned when he brought it out we wouldnt be in this situation now and short of cars on tarmac

I dont claim to know much at all about the build and spec of saloons so from my view point of an outsider looking in this seem like madness! Why would they want to change the spec so much? I also hear from my mate there is lots of unhappy 'loon' drivers Crying or Very sad

If there were lots of unhappy drivers then things would be ok, too few drivers is the problem. This is a formula in need of major surgery.

I think the rule changes are primarily to eliminate a need for one car for shale and one for tarmac. The tarmac cars of today are not much different to the F2's under the skin, with everything adjustable within reason which make most cars handle very well indeed.

Cost a new build or even a good second hand car isnt cheap, and unfortunately in the present climate or any other time for that matter the cost does seem to have risen hugely to have a reasonably competitive car in what is supposed to be a 'stock' formula.

The formula needs to go back several years to make it appeal and get more cars on track, unfortunately this means a lot af alterations to current space framed 'hybrids'.

Its not the easiest formula to go into from having little or no experience of oval racing and i'm sure after watching some of the great racing we have witnessed this year many have thought, brilliant! but i'll leave it to those guys Smile

Anyway enough from me i'm off in the garage to look at a 'stock' car .... Shocked

As a current driver with a Tarmac car couple of points i would like to make.
1 Kev which partitcular rule is causing the most trouble. If they need to be scrapped or not economic to modify whos going to buy them?
2 As i understand it are cars will always be a body shell over a spaceframe(similar to a national hot rods but with bumpers).So unless spedeworth cars become space frame the two will never meet in specification.

I am trying to clarify some of the changes to know how much i have to change as i dont want to do it twice but i dont think i will have to scrap my car to meet the new regs.

yes the new rules are primarily aimed at one car for both surfaces, the cars of today are not much different to a f2 but as already stated when eddy darby built his car it should have been banned. i have said this to Hazel at Skegness as long as there is a shale track you wont get as many cars on tarmac whatever you do to the rules as the same people will still win because they put time into preparation, just look at f2 gordon moodie still wins after the rules were changed. the shale scene is stronger than ever as there are 40 cars tomorrow night at lynn
second hand cars are not cheap but for example it is not the only stock car formula where you spend a lot of money, just look at the price of the ex 1300 world champions car for sale, dont know exactly how much, but it is not cheap and that is from the spedeworth field ie cheap stock car formula.
the formula does need to look at change but this will not only affect tarmac it will also affect shale as these cars need altering aswell to be within the new rules.
space frame hybrids do last there are cars out there which are 10 years old will you see this in a spedeworth car lasting ten years, there will be plenty of action in these but no cars as drivers will always be repairing. once you have the car it will last and will be value for money.
i am a avid fan of national saloons and have spent a great deal of time and money following this sport all over the UK for 30 years.
these are only my opinions as a fan of contact racing
