Subaru Stars Traction vs. weight?

This is a question about planning for the winter rally cross on the 15th. What do you guys think about weight vs. traction? Do you think it better to leave a heavy subwoofer box (70 lbs) over the rear wheels for traction? Or remove it for less weight? This is definitely not a 1/4 mile run! Any thoughts?

If it is not bolted in, then the tech inspector will probably make you remove it anyways.

It's crammed and strapped in very tightly.

I would remove it simply because it wont add that much actual traction in snow and ice, it will just pre-load the suspension in the rear more, and take away from effective suspension travel. If its weight will be actually felt, it will be in the extra dead mass causing more intertia in the rear, thus, you'll subtly be fighting against extra sliding. Its like pushing a glass with some water in it, after it stops the extra mass causes it to slide a bit more than it would have without it. And like RallyX13 said, it will probably be flagged by a tech inspector, and you'll hafta remove it anyways. Personally, I dont like the extra weight in my car no matter what the driving conditions. In any form of racing, lighter is always better. The only time they add weight is when the exceed the minimum weight requirements.

70lbs is extreme for a set of subs. My two 12in JLAs are only about 30 even mounted in the box.
Even so it's a very negligible amount of weight.
Also in my experience, a lighter vehicle tends to handle better in low traction conditions provided tires are adequate. The more inertia you build up the harder it is to change velocity.

You haven't seen my sub! The woofer alone weighs 50lbs! Check it:

Thanks for all the input guys, I'll be taking it out for the rally. The drive up won't be as enjoyable but oh well.

a glass has more displacement than a 1/4 cup of water, yet it still is affected.........simple phsyics, regardless if its enough mass to add to the actual effective weight of the vehicle than it will, obviously, have an effect, even if minor.

I took everything out of my trunk, box, tire, jack, cover, carpet, all but the amp which is bolted down. the less weight in the rear the better so you can slide easier by spinning out at the rear tires before the front tires. hence no wing
