Technical Infringement Report #219

Date: Saturday 29 October 2016

Venue: Racewall, Cowdenbeath

Driver: #219 Luke Grief

The 2016 Saloon Stock Cars Technical Specifications state

“..When referring to ANY OF THE SALOON STOCK SPECIFICATIONS NOTED HERIN the principle will always be: Unless permission is specifically granted to make modifications or any variation, NOTHING MAY BE DONE TO ALTER OR CHANGE IN ANY WAY THE STANDARD PARTS. Unless these rules state you CAN do it, you CANNOT do it...”

The Specifications permit the strengthening of a rear wishbone ONLY.

It has been accepted by the SSCA that an arm maybe straightened using heat and then strengthened.

It is the view of the SSCA that the arm in question has been completely cut through, plated, and welded back together up to 35mm off set and on an angle.

The welding back on the angle overcomes the rules regarding all pick points being at the same point. This modification lowers the outside rear arm without lowering the pick up points and gives camber in the arm. This achieves superior handling on the car. THIS IS NOT A REPAIR/STRENGTHENING THIS IS A MODIFICATION TO A STANDARD PART.

QUESTIONS

If this is “just a repair” why was permission not sought to carry out such an extensive amount of work to a part which the rules state must be standard?

If this arm has been bent from racing, where is the damage?

If this arm is bent from racing why has it ended up with camber and stagger all in the correct places.

If it was bent surely it would be bent the wrong way?

If this is just a bent arm repaired how have they all bent the same?

If this is a repair to a bent arm why has the two parts been welded back together up to 35mm offset and on the angle?
