Mr 19"

I,m maybe buying a R&D 6-speed dogbox for my Sierra cosworth, but i would like to know if there is anyone that,s using it on the streets, and not only for track use. i would like to know if it,s a pain in the ass to drive on the road or if it,s acceptable. How is the durability on them? do they need a rebuild every week, or just regular oilchanges?what modifications do i need to do on my car to get it to fit? It,s currently on an Escort. What,s a good price for a good one?


Thanks!
Johnny.
