Hello from Germany!

That is EXACTLY the kind of extension I was talking about.

Is that something you could add on to your hatch? I don't think anybody in the MOT would complain too hard if you didn't take it further rearward than the bumper. I have NO idea just how interfering your local laws are; where I live if the wheels don't fall off or flames shoot out of the exhaust, you're in the clear.

OK, i'll give it a try. Installing this wing to the 5dr back could be difficult. I hope it's made of smooth material.

Taking it further rearward could cause problems with the race control administration (police).

Not sure if that would be helpful while using LPG, but here in Brazil some ethanol-powered versions of the Volkswagen EA827 engines had a water-heated intake manifold. Probably could decrease the distance required to switch from gasoline to LPG in those cold mornings.

There's also a 1985 BMW diesel 524tdA (E28) in my hands. But i keep it in a garage. Here in Stuttgart i don't get a permission to run it in the city due to the fine particulates.

Gotta hate it. Wouldn't be more reasonable for the government to enforce the usage of cleaner fuels on those old Diesel engines? As it's an IDI it would tollerate some pure vegetable oils as an alternative fuel. Or you could even have it converted to dual-fuel Diesel/LPG in order to keep the particulate matter low.
