I like the looks of the CRC dish rims a lot better than anything else out there for 1/12th (everything else just looks funky) but it's all about performance.

lower rotating mass = quicker accelerating
short side wall = less foam flex = better handling
down side is less foam = less mileage
only thing I use though even for club racing

the larger wheel on the procuts allow you to run a larger diameter tire/wheel combo for more forward traction without having a tall foam sidewall.you cut the foam low and still have a larger overall wheel/tire which will give the forward traction due to a larger contact patch and at the same time you will have little sidewall flex to free the car up laterally.

i ran them at our last carpet race down here in florida.i really did like them.they are still too big for my taste so i still had to cut them.they are the perfect size for asphalt though.im sure the size they come will be fine for club racing.they are just too big for when the traction comes up.i definately liked them alot.

i havent run into chunking problems with them but they do seem a little harder.i mostly run the jaco 2 stage double pink front and rear.i have been the fastest with that combo.the 2 stage tires peel as they get on the low side but there is always a price to pay i guess. i just keep an eye on the size and sidewalls

yup.the front goes first too.the edge of the foam lifts off the wrap.
