To get the smallest battery possible ive had to also invest in a Brise starter http://www.brise.co.uk/BMW_starter_motors.html
When commuting in the car to track i use the stock battery, once on the track I fit the little one. Eventually i would like to fit the racing one behind the passenger seat (when that gets fitted) and keep the cable going to the back so i can simply remove the OE once at track and not mess about fitting or connecting the racing one.
These are also not bad value, but they are not as light.

I was recommended an Odyssey battery haven't raced it yet! Starts the car fine.

I bought a second hand red top race battery off Pistonheads for £50 and it weighs a little over 5.5kgs, compared to the 16kgs of the OE item. It cranks the OE starter with no problem and only mod I made was changing battery terminals.
