I think the lowest powered engine from the BMW Z4 is the 2.0 and thats around 150bhp. So its well within the practical / fun range, without being a handful. Its on par with a C20XE Redtop, or a mildly tuned Zetec. You'll be fine without a LSD. Infact I'd go so far as saying it would be more fun and a little more predictable.

Oh, well thats even less power then. Unless your going to be racing it in competition, I doubt your ever going to need it. I'd say its not required unless your clearing 200 ft.lbf

I think I read some where that the car is to light to make use of the LSD so it's not really worth having one?

most ford sierra lsd's are shagged anyway. finding a good one is like finding a petrol station that gives the stuff away for free.
