Porches and FWD cars have most of the weight over the drive wheels. The S2000's perfect weight distribution is great for handling, crap for traction in the snow. It's not that it's light (it isn't), it's that the weight is too evenly distrubted.

In theory weight over the rear means more oversteer, but I would think the benefit of having more rear traction in snow would outweigh that, especially as your prime concern is getting up hills, not ultimate cornering speed.

 

Talk to the older Jocks on here
IIRC they use have bags of sand for winter driving

 

I did some hill climbs many years ago, VW Beetles left everyone else for dead on loose ground...

 

I tried it last winter, weighted the boot with about 100 kgs. Tracton was great, but compromised handling to the extent where I'd rather not move than move in the wrong direction. The extra weight meant once it started to go, there was no recovery.

 

Are you not inducing understeer as well as you're taking weight away from the front wheels?

 

I carry about 40-50kgs of tools etc for work in my boot and over the last week since the bad weather has set in here I can notice the benefits. There is no doubt that to much throttle will cause you to lose traction no matter how much weight you have in the boot. But adding some weight allows you to creep that bit further up the rev range before traction is lost. I normally pull gears around the 2000rpm and try to be as smooth as possible with the clutch and use the brakes as little as possible.

 

Weight made a noticeable difference when I had snow tyres on - I am less sure with RE050s.

 

Well I've just removed the 2 bags of grit from the boot of the car. Result is............. they're going straight back in for the next journey.

 

for the record, i made it to work and home again without any added weight.
if we have an more snow ill give it a try and see what happens
