We went through this on a previous page... guys lighten up the car for a reason. I do run practice, I'm learning tuning.. which includes lightening up the car. I can run a qualifier without a marshal at pretty much max effort running an average lap less than a second off of my fastest lap ever on the same layout.

So... will it take me from middle of the pack to the front? Probably not... but sitting still and doing nothing wont either. The top of the B vs the bottom of the A is often decided by less than half a second at my track. So yea I feel like lightening up the car is the next thing to look at.

Awesome, thanks. So if the aluminum weighs the 15g it claims then that's 9.1g there. So the aluminum is going in the box as a spare.

I would just love to qualify in the top 8 on club/ points days when there is 20 or so cars...Qualify in the A and be done with it. I've been able to bump about half the time but getting in the B always leaves the possibility that something happens.

Whoops, no it didn't.
Plastic front bulkhead comes in at 6 grams

EDIT: looks like i was a few minutes late on my reply .

I did the mistake of running the ProTek 2800 100C Light battery in a main without any practice. I spun out on the tone and had trouble for the first half of the race before i got used to the lighter car. I have since added weight to the battery.

Also have the aluminum front bulk head and find my car handles very well. I can also take a beating if I case the triple.

Thanks to you guys that posted up the weight on the stock bulkhead. That tells me exactly what I need to know.

While the alum bulkhead isn't a necessity. You are seriously too worried about weight!

A b5m lite with a Ti screw kit is pretty damn good! Attention to detail on wiring can potentially save a lot too.

If you can get your car to 1550-1575 you're good. Can it be lighter? Sure. There's a 1000 different variables to racing and the right tires and driving clean consistent laps still mean the most. Losing 10grams isn't going to be the deciding factor.

Don't forget about the al bulk head allowing you to do the Cav bumper mod which means the A mount and its screws and a few mm of hinge pin material can be taken off.

I have lots of al parts - front bulk head, c mount, d mount, schelle rear hubs and my car is 1510 grams because of the slrc chassis, ti screws and 2.4" tires (2.4" tires weigh 18 grams lighter than my 2.2" tires)

1550-1575 is where I'm trying to go. I have a CE that weighed 1605 since the last weight in. Since then I've changed esc (from track star to the justock) and shortened those wires in the process...but I'm sure it still needs more. I want to try a lighter car now that I know everyone else at the track is running around 1550.

The esc will make a decent change. I can't remember how much the Ti screw can save but I'd definetly build a stock car with it.

I couldn't believe it.. but I could hold each esc in different hands and notice the difference. Justock much lighter.

Sounds like you are already close to your target weight with those small changes.

Maybe... I'm going to weigh again before doing anything else.

Go to 2.4 wheels. You'll drop some weight easily.

I make the A main in 17.5 buggy at Sparks anytime I come in from Kansas. I have a B5M CE with an aluminum front bulkhead, stock gearbox, and steel diff and out drives... I can't understand why the car needs to be so much lighter. Corner speed is the key. If a mid motor car over rotates and stalls, all momentum is lost.
