I don't know whether it is the carpet/additive we use but pretty much everyone runs pink or magenta rears in the UK nowadays. Yellow hardly gets a look in.

I've answered you on the Tekin forum.

I agree with you there Trev, although I have found that CRC yellow's last longer through the 8 minutes than Jaco yellow's do. Pink rears are what I generally use on the back here in the UK.

I wish we could use those as they have much less wear, but at our track they heat up too much, and loose grip at 5mins.
They used to work on our carpet, but something changed in the last 6 months or so.
We can get away with mag in stock, but the car will not be consistent for 8 mins.

Perhaps if we were allowed to use Paragon instead of JTG it would be different..

I'm sure at iic they will be the ticket.

We had an inconsistent issue 2 winters ago and last winter we went and rented a steam cleaner and used a really diluted simple green solution to clean it with and we are now using Pinks with 10.5 Timing and Mod

traction lasts now up to 11 min with Paragon FX II

This has been suggested before, we'll have to see if we can talk the track owner into it.
Thanks for the Simple green tip.

When a JTG track on older carpet starts to get hot > 70 deg and has a lot of compound worked into it, it starts to get gummy and clogs up the higher rubber content foam tires like CRC Mag and Pinks.

This issue won't be as bad on new carpet which is why at most big races it's not an issue. If anyone has gone to IIC i believe this is why Scotty keeps the room cool.

Switch over to CRC Gray or Black front's and yellow or gray rears, you should be good. Gray\yellow do wear fast but that's the price we pay to be fast.

Cleaning the track will definitely help the problem for awhile. If the carpet gets run on a lot with foam tire cars it will start to happen again in about 4-5 weeks. Our local track cleans the carpet every 8 weeks, which is a blessing that they take the time to do this as during the summer it makes for a much better racing surface.

This is exactly our issue, though only us 12th scale mod guys really notice it.
And those are the tires that work best for us now too.
Not as fast as Magenta or pink in the first few minutes, but much more stable for 8 mins.

Our CRC rug has about 18 months of racing now.
Last week it was 96 deg ambient, but I'm sure it gets much hotter on the days they are closed with no air circulation.

You should notice in the evening after the sun goes down and the air temp starts to decrease the track get a little faster. Of course in So Cal the temp may not drop much from 8 to 10pm. This winter you should be able to switch back to Mag\Pink.

Are you racing at TQ?

Yes at TQ.
We had the same issue starting around December with the tires, even on cold nights.
But it wasn't always this way, last fall and before that, Magenta was still the go.
Took a while to sort out what was happening.

Up at Nor-Cal where they use Paragon it's not an issue.
I didn't need Yellow up there.

Paragon is the S$#&, it's to bad so many people complain about it's smell.

When i was out there in Feb the grove was quite black and gummy looking. It was great for TC. I saw Bob's 12th scale after a race and the tires where completely glazed. If you can get the owner to try cleaning the carpet every 3 - 6 months it will definitely help with this problem.

Too many racers here say paragon gives them headaches
But yeah, it is the best stuff, and I love the smell

I used to run nothing but Paragon Ground Effect during 90s. They do make an odorless one and FX2 is legal for tracks. Else, Corally got the jack the gripper which I had to buy at $12 per can at TCS carpet event.

What's the best way to tell if the chassis is rubbing on a carpet track? I use magic marker but I think it may be to stern to rub off unless its a chronic problem in the car, any suggestions?

White-Out liquid or tape works great. I've been using the tape because it comes off easily.
