Battery placement for track day car

[jamie077366]

Hi guys, iv not posted on build thread for a while but I’m getting close to completion. Where do you guys put the battery? Two options.... to the left of spare wheel well (hatch) pro’s .... weight distribution and most of weight removed is from the rear...cons... weight is behind back axle.

option 2.... behind drivers seat (no room behind passenger seat as iv located it as far back as possible for weight distribution) pro’s... between axle and low down... cons ... not massively helping weight distribution. I’m aware of safety etc regarding leaking battery’s etc. 

Whats your views guys?

If you look at this pic you don't have to be afraid about weight behind the axle: The dry-sump tank is in the trunk, also the battery and the screen washer tank. And those Grp B cars had an engine that was 6 cm replaced to the rear for weight distribution:

So getting more weight to back seams more important than between axles , thanks 👍

Aye, gets the back end out nicely with more weight to the back

If you are running a standard lead acid battery i'd put it in the boot, but put it in a battery box also (available in plastic or fiberglass) as its in the drivers compartment still on a hatch.

Alternatively look at dry cell race batteries like the Varley red top. They are less than half the size of an original type and can be tucked into a much smaller space.
