[Rattler]

I've been a bit bored today, so decided to weigh some disks!!!!

I'm trying to get the best wheel/disk combination and had a few disks "lying" around, so I though a comparison may be interesting, as the lighter you can get unsprung weight, the better!!!

I compared a single front disk off of a 916 (I think) a single disk off of a 996R and a single Braking "Wavey" disk.

The Brembo 916 disk is circa 1999 I think and weighed 1.85kg.

The standard, alloy centred, disk off my 996R weighed in at 1.3kg.

With the Wavey disk weighing in at 1.375kg.

You can work out all of the differences / percentages etc if you want.

So although there's only 75 grammes difference (x2 for both sides), I'll probably stick with the waveys as they do perform better and look better than the standard 996R disks.

If you've got the standard Brembos - you're giving up a lot of weight advantage if you've not got the later "alloy" ones or Waveys fitted.

The weight differences may not sound alot, but its all about gyroscopic forces and the heavier the front wheel / tyre / disk setup the slower the bike will turn.

If you can get the bike to turn quicker, you can go faster and turn later into a bend and also pick the bike up faster to get on the gas earlier! This can save seconds a lap!!

The 996R and Wavey disks aren't cheap though, with a pair of either costing around the £330 mark.

Worth it? If it can reduce your lap times its gotta be good.

I can post some pics of the different ones, if anyones anal enough (as I am) to want to see them.
