Oem battery + oem mounting kit = 18.0 kg.
Odyssey pc680 battery + Password JDM Battery Relocation Kit = 7.5 kg.
Net savings = 10.5kg

how long will the battery last you for?

dang u going to pop wheelies now... look out!

So far no problems here, even after 3 days car starts without problem

Please report back after, say, 365 days... :p

Lol yah really its not a fiat.

lol i mean 3 days without starting the car.
i guess 2 times a week is enough to keep this battery charged

with my 285lb.azz in mine & a full tank of gas,,,weighs in at 3640...
at the dragstrip,had about 2-3 gallons of fuel in tank/so weighed around 3525-3530...pretty heavy...a diet would be a good start/but i'm 6'6"

Complete Z1 2 piece rotor kit weighting 30.9 kg or 14.4 kg lighter compared to Oem setup!
I wanted them drilled/slotted but seller sent me slotted only :( however weight savings are awesome

South Bend Daily stage 2 kit + silent disc option (Clutch, flywheel, pressure plate) total of 16.3 kg

^^^ Nice!

What's your Z weighing in at now?

Also, how has the battery been holding up?

Wondering the same about the battery as my oem battery has totaly crapped out.

no problems with the battery so far, works perfectly

so lets say i buy the PC680 batt right now, what can i use to hold it down in stock location?

Anyone know.. please? I need to buy a battery as the stock one is very weak (12.2v resting) and only makes sense to replace it with a lighter battery.. Thanks
