RTR Upgrade

TR4A-6 aluminium firewall, required for competition. The kit consists of a main aluminium centre section and two small steel 'ears'. These are made in steel so they can be either welded or riveted in place.

Whilst we call this a Fire Wall it is in fact a fluid barrier. Its intention is to reduce the possibility of petrol finding its way into the cockpit in the event of an accident. The aluminium sheet should be sealed and riveted in place to ensure a fluid tight seal.

The firewall consists of 3 parts; a main sheet and two ears.

The fit of the main sheet is straightforward as there are 'L' brackets welded all around the opening which the firewall can we riveted to. The two ears fit under the tonneau panels and can be riveted to the  join between the main tonneau panel and the forward tonneau panel. There is a small 'L' shaped bracket on top of the wheel arch that the ear can be riveted to  and the is a cut out i the ear so that it can pass from inside to outside of the tonneau panel lip.

Once in place the firewall should be sealed all around.
