241 racing,
l0lzpl0x is correct, all that GPM you added to your car will only make it heavier. Use carbon fiber and it will lighten in up alot more.
What everyone wants is to make their cars faster and to handle better. GPM will weigh you down and wont let you handle as good.
And what would be the point of adding a bigger motor if youre going to slow it down with all the extra weight? I lightened my car as much as I could and still put in a big motor (O.S18TZ).
If you are going to use GPM you might as well keep it stock and save your money cus those parts are doing you no good.If you would of left it stock it would be ligher, faster and handle better (extra weight will make it oversteer) Dont get me wrong, it does look pretty![:@]

241racing, and the issue came when I purchased the GPM chassis, it looks lighter and it does not help when you use the 37/41 spur gears. Many people think wrong when they try to dremel holes to move the engine to get the pinion to reach the small spurs. What you need is to use HPI chassis, the holes are longer so you can move your engine further.

JonKBMW, the carbon fiber parts caould be found in towerhobbies. And having a lighter car will make you better.
