Relocating the battery over the rear axle seems like a good idea to me. I don't know what the electrical issues might be, but the weight distribution would certaily be better.

I was also looking into the small battery kit, so any info would be greatly appreciated.

The only downside I could see would be the expense of the cable to run it up front but I was thinking Ditch tool kit, jack, small battery and save +/- 60lbs.

Shifting new 20 lb battery to back and wich would provide a net los of 40-45 lbs up front and 15-20 lbs in rear.

1.5% weight drop front end .06% drop in rear result in a net shift of weight distibution .9% rear and a los of 2-2.4%.

Doesnt sound like much does it?

How many cheeseburgers is that? :)

I am keen on ketting that weight away from such a high point in the car, so I think it's worth it.

that does ignore and physics involved but i would assume lowering the location of the weight and bringing it closer to the center point of the car would cretainly make this more noticable than 1 or 2 % when cornering at higher speed.

Also one of the issues that can affect is went you go to the track .At least in Drag racing ( not sure about autocross ) and im sure rules vary from track to track . Moving the battery from its original point , and going to the track they would check for the following : TO make sure that the battery is highly secure, that its completely tie down , and also to have on the case of the battery (if you habe it in a case ) and external turning off switch .At least this was an issue while drag racing (which i use to do a lot ) and some friends had some issues with this to the point that the inspector from the track wouldnt allow them to run the car at the track to they had the following this listed .
As far as the only benefit that i can see is the weight , which is not by far much . An if the mayor issue is because you want to upgrade ICP , you have companies like RMR that makes there kit that doesn't required a mini battery .Since its ment to fit the Evo VIII with out anymods .
At least this is the kit i plan to run in the future with an upgraded FMIC ......

If this were the case, then when you're cornering at higher speeds, squat down in your seat and try to get your eyes to a low enough level to be able to see past the dashboard. =) j/k!

In anycase guys, here's how we did our "small battery kit": http://rbmotoring.com/gallery/album24/abx

RB Motoring, I couldn't find any product details on your battery kit on your web site. What's the skinny? (price, amps draw, weight, dimensions etc. Also, is is possible to mount it the other way around (90 rotation)).

the logic use on the weight shift is loosely the same as why open wheel race cars and le amns cars seat drivers in the center of the car and put them bassically on the floor. it is also why fiber glass bumpers and aluminum roofs make such a larger differnece in how a car handels than do lighter seats.

acceleration however would be equaly effected no matter where you romove the weight.

Looks like Buschur has one that fits in that orientation.

Okay, so here's the question.

Batteries are measured in Cold Cranking Amps - The battery industry standard for determining a batteries ability
to deliver power to an engine in cold temperatures.

The stock battery provides 520 CCA and has a reserve of 118 minutes.

I looked at the Baker battery chart and their smallest battery is only 230 CCA. (here http://www.bakerprecision.com/battery.htm)

Don't know what the figures on the Buschur or RB motoring offerings are. Also what are the weights? Just want to compare apples to apples b4 making a decision.

Hmm, about the Buschur one, David said their supplier tells them the battery has 800 CCA - oddly enough he doesn't seem to know much more about the battery though. About reserve capacity he said 'it is probably not really high'. The battery with tray is 17 lbs.

If you're looking at say a Odyssey PC680 (14.5lbs) - when it gets cold that actually only seems to have 280 CCA (it has 680 cranking amps otherwise) and a reserve capacity of 28 minutes. If you go a step bigger on a PC925 that has 470 CCA, but it's a lot heavier.

You could also go for a Xstatic battery, e.g. model 800 you'll get 800 CCA in 10 lbs... sounds pretty good to me.

Good move on lightening up :)
