Hi Andy,
your car looks really beautiful. I like the way it is modified. You are strongly restricted by the rules, but on the other hand you have real racing upgrades like hanging pedals with balance bar and a hydraulic clutch. The radiator looks great, as well. We would like to see some photos of your engine bay, as well.
Are you allowed to use anything other than the stock brakes? If not, I would like to know, how your brake feels during races and how you chose the master cylindres. My car has very similar data (158 HP, 670 kg) and it was lots of try and error until the brake worked well for the first time. At the begining, we used the stock one-circle brake with booster, but it was rediculously bad. After that, we installed a Porsche 911 tandem master cylindre, because my Dad raced a 911 before and the braking of this car is really great. But this did not work out well with the tiny discs and drums of a Europa. With 0,7" at front and 0,625" at the rear circle the brake began to work well, but you have to push the pedal sooooo hard. After that we changed the front master cylinder to 0,625", which made the pedal "softer", but destroyed the whole balance, as you can see on the attached pictures.
For the next season we are going to keep the front cylindre, but take a smaller one for the rear brakes, as well. AP-racing makes master cylindres down to 0,55". The result should be an equal balance as before, but with a pedal, which can be used without brute force.
Your regulations seem to be even more restrictive than mine, but I am still not allowed to use rear brake discs or wider discs at front. With the braking assembly of a Type 47, it would work out much better, but the FIA says no.
@BDA: The Europa's advantage is certainly a higher cornering speed, but the braking distance is despite the relatively low weight not as great as you would imagine.
