Hey guys, it's been a while.  Life and stuff got in the way for a while, but I'm back with some fresh eye candy.

I'll start with the predawn show.

(ps. Scud, I love your flamethrower)

And just after sun up, with some loooooong shadows:

Love the shots, look amazing.
I found it interesting that only the GTR had the front calipers at the front of the discs. I wonder if there is any mechanical advantage as to where theyre placed on the disc? All I could think off is moving weight towards the middle of the car would be an advantage. If thats the case you would think the GTR being front engined would have them at the back of the disc.

Firstly, great photos Shane.  Good to see you back. :thumbsup:

That is an interesting question AFU.  I have often wondered if it makes a difference to how a car brakes depending on where the callipers are.  Using Newtons Law, does it make a difference  to the load on the tyre or is it irrelevant as braking loads are already high.

The Red Bull F1 cars have them below the hub to lower the center of gravity.
A possibility may be the air is easier to duct to the rear of the wheel so it can better cool the disc if the caliper is not there.
Another possible reason would be the loading on the suspension under brakes may be better.

My money would be on the cooling of the rotors better.

I do remember in The Advertiser 3 Hour race one year Pitmans ran the brakes calipers on their bike behind the legs not in front as the bike is supplied. No one noticed it was different as the only changed it after practice. made the bike turn in better.

Again, nice shots Shane! Must be hard work in the dark.

Stretching back to my F-SAE days the calliper position does have an effect on forces through the tyre. At the front of the car the reaction from the drag against the disk adds to the wheel load when calliper is at the rear and subtracts from it when in front. Hence the common logic of callipers in the middle.

As PA noted cooling may also be a reason to move them. From memory the rotor position was only a fairly small percentage of total wheel load so actual effect might not be significant if offset with more favourable temps for instance.

Yeah, panning with something moving at 200+ kph in normal daylight is a bit boring now.  :)
