I'm a bit confused as to why anyone would want to move a corolla battery to the boot. I mean, its not like your pressed for space and its not a huge weight shift. And come on...would you like that acid and hydrogen inside the passenger compartment (it doesnt take much flow through from the boot).
Supra, Skyline, Silvia etc etc I can understand, gotta put those intercooler pipes somewhere... Its not like your pressed for room in a corolla engine bay...
In conclusion, ricers suck.
(P.S. just to make it clear, this isnt an attack on you KE30Coupe...just the previous owner...stupid ricer)
