i have recently started running 21.5 lipo and it seems like every one is so worried about getting there car down to the 38oz limit. i have done some of the safer things to my car to save weight like shortening all the wires to were they are just long enough shaved a little weight on the battery tray, painted a new body with just a few coats of paint instead of layer after layer. my only problem is that my car is still almost 39oz which is still almost a full ounce over weight. so my question is this one ounce really going to make that big of a difference or is it worth cutting your chassis and going to the extremes to lighten this car just to lighten it one more ounce....

One ounce does not matter at all.

Exactly! An ounce does not matter. Just drive and have fun.

Larc You Would Be The One To Know If That Ounce Would Make A Difference On My Car Since Its A Stryker... The Best D@mn Car On The Market

I found that it is nice to have a light chassie so you can add weight to the area that needs it.

.... so my question is this one ounce really going to make that big of a difference or is it worth cutting your chassis and going to the extremes to lighten this car just to lighten it one more ounce....

IMO.... less than an oz.
no.

is it worth cutting your chassis and going to the extremes to lighten this car just to lighten it one more ounce....

If you don't know exactly what you're doing you may very well end up ruining that chassis.

Well I Have The Ability To Cut The Chassis Without Damaging It But This New Stryker Car Works So Good I Dont Want To Change A Thing... Was Just Wanting To Lighten It Up A Bit

I think Mr. Paradis was thinking more on the lines of,
if you cut it in the wrong places, you will ruin it...
Not the quality of the machining/cutting process...

Doughboy, It takes Alot of chassis graphite to make an ounce but little things like the how you paint and trim your body can save you substantial weight and lowers your center of gravity. Some of the adjustible aluminum body mounts look great, but cheap nylon post are lighter, same thing with wing mounts. Any screw that extends more than one thread through its nut is to long. Aluminum screws in low stress areas are cheap.
Also Do you really need that big foam front bumper? :p

Just pointing out theres lots of little things that cost next to nothing ( or can be cheaper than what you have ) that can save you weight.
Weight on any race car is important. Find 28 places to save a gram and you just shaved off an Ounce.

Makes no difference, Set-up, drive line and hitting your marks = faster laps

Dan, You read my thoughts!

Then I would say, dont change it! Weight is important, but if your within an ounce of the min, your fine. Work on other things mentioned. Setup, driveline, etc.

If the car and driver are on weight does make a difference. :thumbsup:

If the car and driver are on weight does make a difference. :thumbsup:I agree with Frank on this one.

I agree with Frank on this one.

So do I, but cutting the main plate to try to shave off an ounce will not work. I got out my old KSG solid plate which is quite a chunk of graphite and weighted it at 3.1 oz. You would have to cut a significant amount of graphite in order to save even as much as half an ounce. Now that Stryker chassis doesn't look as it has that much extra material that you could cut out without affecting the chassis rigidity or torsional strenght. Mind you, I have only seen it on pictures and never had it in my hands.

Now, DOUGHBOY, don't get me wrong, if you want to try your hand at cutting some of the material out of your plate, do it, but do it with a plan and for the right reasons. What are you trying to gain by this? If it's just weight, don't bother, risks are too great, IMHO, for the possible gains and there are better ways to do it without risking ruining your car. (lighter body/paint job, smaller electronics, running smaller tyres, smaller gauge wire on the speedo, lighter wing/wing mount if you run one, aluminum screws on parts with limited load...)

If you want to change the flexing caracteristics of your car, well then you may gain something, and save a little weight as a bonus. Just sit down, think of what may be affected by removing this or that part and be ready to scrap a couple plates if the end results are not convincing.
