I must confess to be frightened by the idea of foam for all the reasons stated.
For my S4, and complying with FIA regs etc I use a QED wet baffled sump. No problems although I do overfill by half a pint - still misses the crank.
Last weekend at Greek circuit which is very tight in some parts and fastre open corners elsewhere, the car was on pole in front of 911's, GT40, Fords, lafas etc and as we use slicks it was pulling plenty of 'g' and also outbraking the bigger braked cars. No surge or loss of pressure [ when I dared to look ]. Traditionally I would go for dry sumping but now find myself wondering just how much bhp loss there is with a wet sump as it is so easy and cost effective.
My advice to the original question is a baffled sump, problem solved.
