There is a trade-off between unsprung weight and cooling, of both brakes and gearbox. On our Chevron based Can Am car our brake temps were fine on relatively high speed tracks like Road America and Mosport but cooked the rears (and CV joints) at Mid Ohio, resulting in DNF. I think that cooling is why inboard brakes are not seen much today.
Just an anecdote which may have little relevance to your Elva.
