What brake fluid would people recommend for use in conjunction with wilwood m/c's + calipers, and standard rear drums, the car will be used on
track...

You will get lots of differing opinions, but I recommend going with a good normal dot4-5 and change it at least once a season.
I don't like silicone for lots of reasons, but one being the extra expense.

same here, my bakes fade well before anything happens to the fluid, though if I was going to race something perhaps I'd invest in something
fancy
I didn't change the fluid on the bluebird due to its pathetic mileage per year and given the fact that most of the time it sits in the garage.
Wish I had though as when I took the drums off I found it was leaking! Leaking at 40k I was stunned  So I took the slave cylinder apart (their
aluminium) and found it was covered inside with a hard brown varnish that had torn the seals. New cylinders have been fitted and I'll give it
proper yearly changes regardless of the use it gets, strangely the brake fluid was perfectly clean looking.

The higher boiling point fluid you use the more water it will absorb.
Water has two bad effects
(1) It lowers the boiling point of the fluid.
(2) It causes corrosion
For track use I strongly advise using Dot 5.1 fluid but change it at least every year --- you don't have to completely drain the system just
bleed the fresh fluid through.
For a book Locost that dosen't see the track DOT 4 fluid is fine change every 2 years.

Dot5.1 every time for me - it is compatable with Dot4 but I THINK it is less corrosive to paintwork.

Don't use dot5 as the calipers are almost certainly assembled using non-silicone fluid and they do not mix at all well.
dot5.1 should be fine though which is what i use.

if you are going to pay for 5.1 check out the AP stuff on Burton Powers site - it's pretty cheap for something that is good quality.
£4.50 for 500ml
