Autograss Racing Classes

Class 1 & Junior Saloons

This is the ideal class for beginners in the sport, those racing to a low budget and is also the only saloon class where 12-16 year olds are able to race in. It's also a class that people with previous racing experience are keen to join.

A complete family often participate in this class with the same car - Dad racing in the Mens category, Mum in the Ladies and their Son / Daughter racing in the Junior category.

There are no special tuning modifications allowed in this class, the engine / gearbox must remain basically standard within strictly enforced maximum and minimum tolerances. This helps to ensure that costs are kept within affordable limits and that there is very close racing both at Club and National level.

Once more, to ensure that the field is kept as level as possible, there are a limited amount of vehicles that can be used. At this time, this includes: the Classic Mini Saloon, Citroen AX, Toyota Yaris or Nissan Micra. The engine and gearbox must be from the same car and using an engine no more than 1000cc capacity.

 

 

 

Class 2

This class is another great one for beginners to the sport and for starting their Autograss career; those racing on a low budget and those who wish to race either front or rear wheel drive vehicles, although the front wheel drive cars have become the far more dominant over the years.

There are limited modifications allowed in class two, the engine and gearbox must remain basically standard within strictly enforced measurements. All the fuel-air mixture must pass through a single 32mm diameter restricter.

These measurements help to ensure that costs are kept well within affordable limits and that close racing remains at both Club and National level.

Cars that may be used in this class may either be of front or rear wheel drive saloons; estates; hatchbacks or front wheel drive saloons or hatchbacks.

The engine must be of a maximum capacity of 1300cc. To limit the use of 'odd' or 'specialist' cars, the type of vehicle make and model are restricted to those listed in the original 'Palgrave' or 'Glasses Guide Technical Services Data Manual'.

At present, there are over 200 types of vehicle permitted to race in this class.

 

 

 

Class 3

This class is ideal for those who want to put a 'big' engine in the place of the original. This is a very popular class with a lot of sideways action.

The class three cars resemble stadium 'hot rods' as they used to be and to a certain degree, still are now.

The car used must be a saloon or hatchback and be rear wheel driver. Any front engined, front wheel drive saloon with a wheel base of 2400mm or more may be converted to front engine - rear wheel drive vehicles.

The 'Specials' Class 8, 9 & 10 

These vehicles with a steel tube spaceframed chassis, either home constructed or professionally built are divided into three classes by the application of an engine capacity and / or engine type limit.

These 'specials' are specifically designed to be strongly built enough to withstand a collision or roll over, but are not fitted with bumper bars as deliberate contact is definitely not allowed.

There are unlimited modifications allowed, the engine / gearbox / transaxle / axle are free according to each class cc limit and specification. Specials are fitted with a multitude of engine types with 1.0 / 1.1 / 1.3 / motorcycle / 1.3 / 1.4 DOHC engines / 1.8 / 2.0 SOHC &smp; DOHSC engines / 2.1 / 2.5 DOHC engines / 2.8 / 3.0 / V6 / 3.5 / 4.0 / 5.0 and V8 engines, mainly mid or rear mounted to Hewland / Renault / VW gearboxes or direct drive.

All of the specials classes are very popular with both spectators and drivers alike as many are geared to achieve in excess of 100mph! Now that, on a 400m track isn't slow!

 

 

 

Junior Specials

These are a junior version of the adults specials classes, with a full spaceframed chassis. Some are made from 'used' adult specials.

All vehicles must use a Vauxhall Corsa 1200cc engine, plus specified Vauxhall gearboxes, original style struts and driveshafts. No engine or gearbox modifications are allowed, apart from some basic reconditioning.

With cheap donor cars plentiful and older chassis' easy and cheap to come by, this can be a very economic option for the children to enter the sport. The engines and frames are often seen to last an entire five year career!

Professionally constructed cars are also available ready built or in kit form. Drivers of these cars must be between the ages of 12 and 16 years, although adults may drive these cars at single day Club meetings, often in specific 'dads' or 'mums' races.
