   Right,
   
   Lets say
   
   1.1 Zest Shell - No PAS, No Sunroof
   Cammed 16v Lump
   Stripped as much as humanely possible
   Full GTI/VTS Running Gear
   
   Any guesses as to what weight I could get it down to?

   Too many factors like exhaust, windows, body panels, etc
   
   It would be nice to get a saxo/106 down to about 700kg

   This sounds like a job for an overly complicated Excel spreadsheet.
   
   Watch this thread, I shall be back after much coffee and some spreadsheeting!

   Forgive me if my Excel skills are still a bit rusty

   Touch over 700kg maybe. 1 (lightweight bucket) seat, no dash, no interior at all, all un-nessecary metal work removed, poly windows, take a hole saw to anything non structural, minimum wiring loom, fibreglass panels where possible (bonnet, boot) etc etc and you might get under the 700kg.

   Running 160bhp minimum with 700kg car works out at a nice 230 bhp/tonne, just don't crash.
   I know you are trying to save weight, but don't compromise on safety, Get the lightest roll cage you can

   OMP do a 19kg rollcage.
   I still think it will be a struggle to get under 700kg without some specialist parts. Every component will need to be looked at, such as choosing the lightest damper units, exhaust system, manifold etc. You will need a nice budget!

   depends how much lighter the 106 shell is over the ax.
   
   I have managed to get my ax down to 700kgs with a cage.

   I have seen the omp 19kg cage. I wouldn't like to have a bad roll in it. Like standing on a cage of straws

    It may not be good for rallying but it will certainly be up to the job for a track car compared to a car with none...
    I'd only go stiffer if the chassis needed it or I was racing...

    Not a chance in hell of getting a Saxo down to 700kgs
    
    There was one on here once (Bill his name was) who got close but he literally went to the extent of comprimising safety
    
    Only way you'd get close is to spend an absolute fortune and carbon/fibre glass any panel thatd bolted on

    Thats some sachievement considering he started at NCAP level 2
    
    When you go to the extent of cutting out of wirse from the loom that arent needed and removing soundoproofing you may as well not eat in the 24 hours leading up to when you're gonna be racing or hey, hire a jockey!
    
    All seems a bit over the top to me when you get to that level

    730kgs sounds like a reasonable weight man
