Thanks for the feedback guys.
Both nuts off (and both bolts clockwise threaded for future reference). I used several old bolts to jam the hub and stop it turning - after breaking a drill bit, an alan key, the 6in nail that has never let me down and 2 screwdrivers. And the best breaker bar ever - a 4 ft scaffold bar with a really heavy base welded on. I think it is a 'tamper', used to flatten the surface before laying paving stones. It was in the garage when I bought the house 12 yrs ago. Unused til I bought the VX and now the ultimate tool!
I am very interested in the points made by Tony and Martin. I will go the electroplating and powder coating route instead as I don't have the skill or tools to re-engineer the wishbones after treatment. And, I have brand new bushes, ball joints and nuts and bolts to try and fit in this process, all of which will have their own challenges.
I am also fitting the Spitfire engineering toe link (and brace kit - I still haven't measured this Gaz, its on the 'to do' list) and VRSAS kits. This assumes I can get the track rod ends off the steering arm - I have the tie rods off but I had to use an angle grinder to cut both the tie and track rod bolts at the uprights - so the track rod ends are still on the steering rack at the moment.
The calipers are being sent for refurbishment and car will go in for a full service (including timing belt change) and a geo set up.
I am thinking about increasing the power too. I will leave this until next winter and just enjoy the car this summer when I have it properly set up. However, to add to the general debate on this I was reading recently that Cosworth built a triple that generated 250 bhp as part of the proof of concept for the Valkyrie (V12 - 1,000bhp and 206kg). That is the engine (with a 6 speed g/box) that the VX needs as it will presumably weigh a lot less than 206kg, as it has 9 fewer cylinders. We just need to persuade them to build it.
