please go on ( dont! stop! --- oooh dont, stop! dont stop !! )
I am thinking of getting an s15 silvia Soon ish - reason being I dont think I want something as chunky as an r34 , sunroof meh.. nice to have - but the only reason I was going for the spec R is the helical LSD_ but you have just advised me in a very convincing post that both the spec R and the Spec S have this - so I would rather get a tidier spec S and spend a bit less and kit it up myself if I wanted rather than makde the uneductated decision to buy the spec R in the false beleif its the only one with the Helical LSD
