The 1500 includes the composite diff pieces, according to Capricorn they save 30 grams so I deducted that to the current weight of the car.
Ok here is the list of the changes I've done and if possible the weight save which goes with it.
All weights are in grams
New transponder 4.6
2x low profile servo's 44.5 a piece
normal servo's 60-65 a piece
All wiring shortened
No Receiver cover, receiver taped to throttle servo
Alu. pivotballs 1.4 a piece
original pivotballs 3.7 a piece
nylon pivotball retainer 0.3 a piece
stock retainer 0.6 a piece
All Titanium trackrods, steering, upper camberlink, ARB link
Hollow mid and 2 speed axles: 19.5
Lightweight first and second gear adapters.
Lightweight brakedisk retainer
Xceed brakedisk, machined to 27.8 diameter
Capricorn diff internals
Total clutch weight: 30.5
All Titanium except all bottom screws.
Aluminium screws in gearbox
Magnesium screws for suspension (fr. ARB)
Also Titanium screws for engine mount and the engine itself.
Titanium screw for fastening wing to the body.
I think this is pretty much it.
Currently the car weighs 1528 with body and the original bare xray rims.
The weight which I will be putting into the car weighs 203 so it will end up weighing 1699 or 1700 exactly.
Off course it could be that I was just unlucky and got a bad one.
But the fact it snapped under high load, the car was just shifting to second in a very fast, banked corner, I just don't trust it anymore. I never had a DNF all year because I take great care of my car, and that is one of the reasons I ended up in a fairly good position in my first year in the nationals.
