Very interesting... Sounds like our asphalt track where we spray Mt. Dew. If it rains or sprinkle's and you try running on it before its completely dry your tires get coated in a sugar glaze.

Who would have thought getting traction on carpet would be so hard...

We fought through the glaze tonight and managed to get some decent practice in.

Maybe it's time for an SC10.

I think its Karama... Must I bring up the great Crutch quote of 2008?

New to electric I hit the track on a day when it got hotter than the rubber I had, but what I did have was nitro foams sitting in the pit bag, a quick change later and I was on rails, most fun I have had with my pants on in at least a week...

Our outdoor tarmac track can't use traction compounds, but with the run on basically old used foams, I was left wondering why not, apart from everything else I was getting .2mm wear per run, and the foams I was using cost like a third what rubbers are, grip was so high I'm guessing 45's would have still worked, with no issues to do with temp either.

The crap on your tires means that your rug is dirty. Vacuum the rug till it's clean, change the bags/filters, and do it again. We have the same problem if we don't vacuum the rug often. We have a dirt track in the same facility.

Filters and filter bags clog up with dust long before the bags are full. To really get the fine particles and dirt out of the rug, you need to change them quite a bit. This is why I only buy the generic/cheap bags for the rug.

I have to say this thread has me seriously wondering if we want to make the switch to rubber. We have run foam for 4 years and have had no issue with this. The newer style of foams are pretty nice with the lower side walls.

Ill have to post this thread on our track to have some of the racers read this. Thanks Aaron
