I have found that in the rain the screens are the least of my worries! Generally they are not much use as I sit so high in car no2. The more recent cars had a footwell and seat redesign so that you sit more reclined, legs straight and much lower and I think that will make all the difference. Mine are the adjustable Brooklands. Interestingly Pembleton have designed a different solution on the four wheel T24 which could easily be added I think and has no gap between base of screen and scuttle. Only new car I will however go with the Brooklands again. I nearly always wear a Davida Jet Helmet and Visor.
