I mean this literally puts it behind the front axle, as compared to the usual mounting position(front). Anyone fancy doing it? Cheers,

You would get roughly the same effect moving 1kg from the underbonnet area to the boot. Lets assume the battery weighs 10kg (wild guess) - this would mean moving the battery is about ten times more effective than moving the calipers (as well as being 100 times easier!)

Nobby Unregistered N	A few points worth noting: The calipers would have to be swapped over (left to right side etc) as otherwise the bleed nipples would be at the bottom. The calipers have 2 different sizes pistons inside for a reason, 1 leading (bigger) and the second smaller. Would these still be in the same place? Sound pointless to me too.

Vas Unregistered V	and fabricating special brackets to hold the calipers the wrong way round is going to add weight/cost/complexity. Another point to pointless from me then $\:\)$ V.

I just hate to think that we've figured out what could and couldn't be done and there's nothing left to do $\:D$ Last edited by DavidL; 02/01/2008 07:21.

Nigel, thr battery weighs anywhere from 15-25kg(depending on the capacity/amperage) $\:P$ Moving the battery to the rear where the spare wheel used to sit was the first mod I did, followed by the carbon bonnet, it really transformed the way the car handles...but it's addictive, so I'm just looking for the little extra cherry on top of the cake $\:D$
