You will see it only if you know it's there...

In the attempt of keeping down the temperature under the seat of "The Dirt-One" (all the electronics packed in such a small place can become very hot), I decided to turn all the alluminium plate under the seat in a big dissipator.

Also made an extention to act as mudguard/airbox

It looks like the rear diffuser on sports cars

Almost invisible when everything is in place... but you know it's there..

Thanks Enrico!
