I am all for those rubber wheels on spec/stock racing. They LOOK SOOOOO COOOOOOLLLLL.

For mod, and even limited mod foam tires are the only way. For stock racing, rubber tires would wear longer and free the car up.

I have a question that may or may not get some debate going...carbon fiber vs kevlar for chassis construction.

Carbon is lighter and more rigid than kevlar. Has anyone used kevlar layers in their carbon chassis? Or hybrid carbon/kevlar? There are some awesome hybrid material available...even colors.

If the cars are coming out lighter with the lipo...is there an advantage with added weight, flex or cost by using some or all kevlar in the new chassis? I think the flex could be kept out with a layer or two of carbon.

Just some food for thought....

I have a quick answer for you, I tried it once, both the hybrid and the full Aramid/Kevlar material and found it to be unmachinable... You just cannot get a clear cut through Aramid fibers, you are only tearing them apart resulting in an extremely ugly edge (if you can call it that).

But maybe I was using the wrong tools ;-) you can allways try and let us know.

yeah, that makes sense. I am not a composite guy but I have been involved in motorsports and another full size project that used carbon.
I am used to molds in the manufacturing process and not machining...I do know you can inlay kevlar but not sure if that helps or not.
If there was a way to manufacture...are there advantages to using kevlar in chassis construction? Cost savings, extra weight?
