You can try aluminium screws on low stress areas...

Try www.speedtechrc.com He has whole Ti sets. The problem with aluminum is if its used on the bottom of the chassis the heads get torn up, and wont let you get a allen wrench in. In high stress areas they simply break leaving you to try drilling them out. Stainless weight the same as sock steel, so no improvement there. Ti really is the best solution to loosing weight without sacrificing strength.

Actually, SS is generally heavier than regular 'ol carbon steel, dependant upon alloy, of course.

Another problem to watch for is "Bi-metallic welding". Two dissimilar metals can fuse when under stress, and after a period of time. Anti-seize should be used between aluminum and titanium, as these are two metals prone to fusing.

Shorter wires,use lighter rims,use a small ESC like the Novak GTX for example,use a Futaba 9550 like servo,use the Ko helios' receiver 302f.....Or use smaller capacity cells as newer high capacity cells are heavier.

Anyway,the legal weight for racing is 1.5 KG.... Make sure your's won't be under weight after the diet program...

Josh,

How much does the car actually weigh?

I remember it only being around 20 grams over the minimum limit, which is fine for racing.

An underweight car can be a real pain in the butt - besides from finding room for all the weights, you have to keep checking the overall weight every time you run a different set of wheels, motor etc to make sure it's still legal.

You aren't going to save too much weight with the screws - getting rid of the battery strap is the easiest way to drop weight, but using tape can be annoying. The Mi2 battery strap is one of the better designs out there too.

Having looked over your car a few weeks ago I'd say start with repalcing all the worn steering components and set the steering bellcranks up straight before worrying about a few grams of weight.
