BSCRA Production Chassis Policy

Updated November 2017

General

Production chassis are defined as commercially available chassis made from either steel or brass using a stamping / pressing / forming process.

BSCRA only allow 2 piece production chassis that allow compliance with the car dimensional standards without modification. 

For 1/24 production chassis, widely raced in the US, BSCRA will accept USRA approval (where applicable) as confirmation that those production chassis meet the general criteria of commercial availability and manufacturing method.

BSCRA will also consider non USRA approved chassis in accordance with the BSCRA policy.

For 1/32 production chassis, BSCRA will ensure commercial availability during the defined approval period.

BSCRA does not have any involvement in the commercial arrangements between traders.

Scope of Application

The approvals policy only applies to chassis used in the following BSCRA classes:

Class 4            -            1/32 Production and Super Production    

Class 8             -            1/24 Production

ISRA Approval

The International Slot Racing Association (ISRA) is the international governing body for slot car racing.  It is important to note that most of the production chassis raced in the UK are manufactured for the international market. 

ISRA operates an annual approval process whereby 1/24 production chassis may be added or removed from its approved list..  This approval is for the ISRA class,  the BSCRA class 1/24 production class is  not identical to ISRA.

BSCRA will adopt ISRA approval where possible to simplify their approval process. However, there are a number of chassis already approved by BSCRA that are not on the ISRA list.  Generally these will continue to be BSCRA approved thus allowing BSCRA members to continue using their existing cars unless BSCRA considers there is a clear performance advantage over ISRA approved chassis.

BSCRA Approval

The BSCRA Constitution defines how BSCRA will approve new chassis .

Chassis Modifications

No modifications will be permitted to the two pieces that make up the chassis, unless specifically mentioned in the rules.  Chassis must not be bent from their original intended shape / profile, unless specifically mentioned in the rules.

The original motor bracket in it’s original position must be used driving gearing on the intended side 

Permitted construction techniques are listed for each class and these generally apply to assembly and tuning possibilities.   Specific restrictions are also listed for each class.

BSCRA Class 4 and 4A - 1/32 Production and Super Production

 Two piece, stamped / pressed brass or steel chassis homologated by BSCRA.

Approval will depend on compliance with chassis design (two piece), material and manufacturing method.

In approving chassis BSCRA will consider allowing specific modifications to that chassis based on the following criteria:

·         Obvious weaknesses not covered by general bracing / mods already allowed

·         Options for different chassis construction “out of the bag”

·         Restricting techniques that may be employed to influence chassis movement, depending on assembly options

(Clarification   Chassis must be of two piece construction of sheet metal, either steel (including stainless steel) or brass.  The metal may be plated,

 The two pieces shall be linked by a single piece of wire, a split pin or two screws.

Any cutting method may be used.  Material may be formed to shape but the thickness may not be modified from original other than by the changes that are caused by the forming process)

The BSCRA rules contain

General construction techniques are allowed to all chassis where appropriate

Construction restrictions that apply to all chassis:

The list of chassis that are currently permitted for BSCRA classes 4 

The permitted modifications specific to each chassis.

BSCRA Class 8 - 1/24 Production

Two piece, stamped / pressed brass or steel chassis homologated by BSCRA and, where applicable, already approved by ISRA .

Approval will depend on commercial availability, compliance with chassis design (two piece), material and manufacturing method.

In approving chassis BSCRA will consider allowing specific modifications to that chassis based on the following criteria:

(Clarification   Chassis must be of two piece construction of sheet metal, either steel (including stainless steel) or brass.  The metal may be plated,

 The two pieces shall be linked by up to two pieces of wire, a split pin or two screws.

Material may be formed to shape but the thickness may not be modified from original other than by the changes that are caused by the forming process)

 

BSCRA Product Approval Process -  Chassis Approval Form

Introduction

BSCRA production class racing in both 1/32 and 1/24 is restricted to BSCRA approved chassis, and BSCRA welcomes the submission of new chassis from any party (‘the submitter’) 

It is the submitter’s responsibility to understand, and demonstrate to BSCRA that the new product complies with, BSCRA approval criteria 

 Product that is close to the limits of acceptability is likely to need closer scrutiny than product that is clearly inside or outside the requirements, so the decisions on “close to the limit” products are likely to take longer. 

 You must complete this form, provide sample product as described and abide by all guidelines, rules, terms and conditions in order to use the product approval service.

 

1 Chassis name and part number ……………………….

2 Chassis manufacturer ………..

3 Is the chassis USRA approved? (Not applicable for 1/32 )…..

  

All above information is needed for BSCRA to consider a chassis 
Submissions must be accompanied by a sample chassis.

 

Terms and Conditions

1 BSCRA does not expect any consideration for providing this service. BSCRA has no liability for any costs to any parties arising from it, for example and not limited to correspondence, product development, manufacturing, marketing, write off, postage, resubmission or any other costs involved. 

2 BSCRA does not give advice on meeting approval criteria.  Any comment or lack of comment by one or more BSCRA officials that may be construed as advice to a submitter is that individual’s personal view. 

3. The onus is on the submitter to provide evidence that the chassis meets BSCRA requirements.

4 The approval process for a particular chassis ends with an approval or rejection decision: 

The BSCRA Competitions Secretary will send the submitter a formal approval or rejection email. In the event of acceptance, BSCRA will then publish the product approval through its channels. 

In the event of rejection, BSCRA will inform the submitter of reasons for rejection. Rejection will be for one or more of five reasons, and the submitter will be informed:

where the chassis does not meet the dimensions required

where the chassis does not meet the physical construction required. 

where the chassis is not made from the materials required

where there is insufficient evidence that the chassis is USRA approved. 

where insufficient examples of the product will be available to meet demand 

BSCRA reserves the right to inform its members of rejection decisions

 

5 Product can be resubmitted once reworked or with further clarifying information, the submitter following the approval process from the start. 

6 BSCRA reserves the right to change its constitution, rules, policies and approval criteria and may approve new products from a variety of suppliers. This may affect product marketability.  BSCRA has no liability for any costs to any parties arising from these changes, for example and not limited to correspondence, product development, manufacturing, marketing, write off, postage, resubmission or any other costs involved.

 

Confirmation of terms and request to submit 

I request BSCRA to consider making the above chassis eligible for BSCRA racing. 

I accept BSCRA’s terms and conditions.
