Wonder why those 962's got faster?

Well I got an email from Maurizio of Slot It the other day about why the recent Rothman's 962 was so fast. The reason was that the 962 body, starting with the Hydro Aluminum car has had a "touch up" done to it. The body shed 3 grams of weight and it's now down to a light weight 20 grams. The next car to undergo a weight loss will be the Lancia, which according to many is nearly as fast as the 956 Porsche. According to Maurizio that's the standard by which the other car's are judged for speed. The new Martini Lancia will be lighter with a modified cockpit. Further, the Lancia's interior will be modified so it doesn't touch the chassis as it does in the first version, the Malardeau. After that the Sauber will be next on the Slot It weight loss diet.

All of this explains the delay in the production of some cars people have been waiting for....like the Martini Lancia.

It also does raise an interesting point though...let's say you're going to enter a race that's supposed to be "stock" slot it's. Let's say not everyone know that the newer 962 is a lighter body, or the newer interior that came with that body is lighter...you've got a nice little advantage, no? And aren't we all looking for that edge?

I don't think that 3 grams make a difference, a lower center of weight does. The main cause of the excellent performance is that Orange Endbell.
I must say that also the Jagermeister 956 KH is a fast one, mine got a NSR Shark motor as a Sidewinder, with the 18mm 36Z sidewinder crown, and the 6,5mm 10Z pinion. It's the fastest car I've ever driven...

One thing is clear, Maurizio is always looking to improve his products...a good thing for everyone, except the competition.

I was wondering if the 312PBs will have a similar interior treatment as I had to file down the motor pod to allow movement...

Need a physics lesson. Why would reducing the weight make any difference when you are using magnets? Without mags, you add weight, so again, what's the deal?

Reducing weight above the car's CG lowers the CG. Adding weight below the CG lowers the CG.

Reducing weight anywhere on the car increases acceleration and brakes. Reducing weight anywhere behind the guide post reduces inertial forces which tend to make the car slide in the turns.

Tuning is about moving the CG around, and it often helps to have a lighter body.
