Sorry, don't really know the specs, I just call the pacenotes. It was built by Bumeister Engineering for Mazda a long time ago and has been retired since they built our MazdaSpeedy 3 in 2005. Still a great car for slippy winter rallies so Lurch unburied it out of garage and entered it for the sake of good ole times.
Here are some pics from 2004 and 2005 when we last ran it before it bacame the back-up car.
Yes on LSD. Goes great in snow which is why we prefer over using our highly developed MazdaSpeed3 in winter rallies. One cool feature that greatly helps swing the rear where it needs to be is hydraulic ebrake and the handle is relocated directly beside steering wheel and you push it instead of pulling it.
