Wheel Spacers & un-laden weight...

[EssexPorsche]

Quick question chaps - probably one for PL and JD.

I am having thoughts about running spacers on my 2002S. I currently have the 18" Carrera LW's. Thought it would be nice to bring them out a little and stop that kind of old VW Beetle look with the wheels buried in the wells.

However (back to the weight issue - i seem to have a thing about weight!!) - will adding spacers defeat the object of LW wheels by adding to the unladen weight.

Physics tell me the lighter the weight the drive train has to spin, the quicker they will spin up and hence better acceleration? I have seen posts where talk of wheels being the heaviest cast wheels around etc etc - so i figure there is something in the weight issue and therefore should i avoid adding the unnecessary weight just for a few mm of extra track width?
