It may be a little late to offer any help with this but I'll give it a go anyways.
First you'll want to get some street tires, something else I've thought about was lowering it down with shorter shocks maybe? Instead of 110mm in the rear go with 90mm with very stiff springs, not sure what you would run in the front, I suppose 70mm shocks that are a bigger bore also with stiff springs.
These are just some ideas that may work but I can't say for sure as I've never tried, although I am planning to with a old H7 I have laying around, should be a fun project, was even thinking of doing a 2 speed conversion.
