mine for reference Azeka,




That's with rollbar, rear and front Stb (back one is heavy) big battery in the boot, (11lbs one on the way) and door cards in place. Lol and full fuel. so half tank would be minus 20 kgs or so.

if I take -33 lbs for the huge batt for brallie swap out.. (I also have the 15lbs one) installed a week or 2 ago.

33/2.2= -15kgs.. would bring mine to 1376 kgs.. that's 3027 lbs.

Intrested in how you installed the new batt, I umed and arred a long time before finally placing the new batt and its holder.

i /did/ however pull the whole radio/nav thing bit out though..

Thanks for sharing, Vanne! We have very similar mods so this is a good comparison. Interesting how with your heavy battery you are still 90lbs lighter I guess the Radio/Nav/Amps all add up...

As a point of clarification, my corner weights include a 150lb ballast for driver (Will update my post).

With regards to the Braille Battery, I used a Macht Schnell mount for E92, fits perfectly.

For reference:
My z4 non-M coupe
3160lb
fulltank gas
1gal water/meth in rear
52.3% front
47.6% rear
9lb braile in rear
2jz up front
no cage, race seats
all amenities (AC, lcd-screen nav/radio, speakers, heavy wood-grain dash panels)

every time I reduce weight, seems to be from the rear. There is more I can remove, but I don't want to make the front/rear balance worse.

Planning a cage soon, 40lb more to the rear I guess.
