After a lot of searching and deliberation, have just got a Wavetrac LSD. As anyone with a VR2 or Evo engine G will tell you, although fun, the wheel spin issue can be a little tiring at times! I'm assured by Wavetrac themselves that this will fit the F5M42 box and indeed I have already tried my spare driveshafts and they're good. Will be a few weeks before I fit it, but will update as and when and of course hopefully a shakedown at the Ring.
