DCD - Thanks for your ideas.
Would fit the additional water cooler, but running out of space - Huge intercooler, Large Alu Radiator, Air con condenser and fuel cooler in the front. Left hand side - huge oil cooler and electric fan plus water spray system, right hand side, blow-off valves and horns. I would not know where to fit it.
I will be in Tokyo next week - Do you have any idea how far say Top Secret or Mines is away from Tokyo (Otemachi specifically) and how one would get there? Train, Taxi? I understand you get your car done by Mines and Top Secret - are they open on a Saturday? Just want to go there buy some stuff I need and look at some of the cars the are set up to have a good balance between track work and everyday road use.
Thanks Again.
