Thanks for that addition, it's the first I've seen of a number assigned to the weight gain for that aspect of the relocation.

Moving the battery to the trunk is a great idea. It helps even out the weight. Our cars are very nose heavy.

Im not totally against relocating the battery, dont like the idea of battery fumes in my trunk. Also I went with a lighter battery and would have slow starting in cold weather. I think if you spend more money on a lighter H.P. battery would be the way to go. they're expensive.

I run a Braille battery behind the passenger seat inside the cabin. It's a sealed lead acid. Braille's aren't cheap, but they are very light and dependable.

Still I don't recommend the smaller ones for daily use. They can work, but they have a low reserve capacity

Seems like I did the math and the cost verse ponds lost wasnt quite worth it for me.

moving battery is not in the spirit of overall weight reduction, but balancing out the car. The stock battery is at the nose, putting 40 lbs right at the far end nose of the car. moving this into the trunk moves weight over the rear wheels which is good for this car, especially if you already removed your spare tire. Either keeping the stock battery or going with a smaller one.

i used these cables:
TEMCo Welding Lead & Car Battery Cable WC0179 - 30' Black/Red (15' Blk, 15' Red) 2 Gauge AWG - - Amazon.com TEMCo Welding Lead & Car Battery Cable WC0179 - 30' Black/Red (15' Blk, 15' Red) 2 Gauge AWG - - Amazon.com
(although i would recommend going with more than 15', 20 would give more headroom for placement)

these terminals:
Amazon.com: NOCO TZKIT1 Lead-Free Top Post Zinc Battery Terminal Kit: Automotive Amazon.com: NOCO TZKIT1 Lead-Free Top Post Zinc Battery Terminal Kit: Automotive

and you need some 2awg copper lugs
Amazon.com: Pico 4539C 2/0 AWG Battery Cable 3/8" Tubular Lug Ring / Eye Terminals 15 Per Package: Automotive Amazon.com: Pico 4539C 2/0 AWG Battery Cable 3/8" Tubular Lug Ring / Eye Terminals 15 Per Package: Automotive

you also need a battery box which depends on the size of the battery you end up using.

cheers
Marko

I think it would be nice to get the extra room in the engine compartment also, just not ready to commit, but thanks for the parts list Marko. Would def. go with trunk compared to rear seat area. So you ran the ground cable all the way to the block?

you only run the +12v cable back, ground goes to chassis, so block to chassis in the front of the car and battery to chassis in the back, grind away some paint and install a stud or find a bolt that grounds. the car itself is the common/ground.

adding a datapoint here, stock spring/shock assembly weights 57 lbs for 4 corners, CXracing coilovers are 42 lbs for all 4, 15 lbs reduction. this is using my bathroom scale, so probably +-1 lb accuracy.

Got my Advan hood in the mail. They were hoping to make it 20lbs, but they contacted me saying when they were done, they got it to 25lbs and to get it down to 20lbs it'd be too flexible for a street car. So I told them 25 was OK. I haven't actually weighed it myself yet, but it is definitely pretty light when we carried it into the garage. Hopefully I can get it mounted at some point to see how the fitment is!

likaboss22, I removed my A.C., condensor coil, dryer, prob. i5-20 lbs. It also frees up engine bay area. Helps with oil filter changes. There are days in the summer when I miss it, not sure it worked anyway. The aluminum lines and fittings get brittle and weak.
