The most comprehensive resource for the early mini fan anywhere

Another long gone tuning concern is FORSPEED, based at a small garage / filling station near Huddersfield in West Yorkshire. This company produced a decent range of tuning equipment some manufactured to their own designs, some bought in from other suppliers.

I can't see any trace of them after about 1966, they probably suffered by having the local Speedwell dealership just down the road.
