i run at this same track as steve. i have had some of the gumming with the front tires too, but not to the same extent. have been running grey rears and purple fronts. i am getting a little push bythe end, but managable. i cut down a new set of tires sunday and i noted that after the main i had NO glazing of the front tires at all. i run more caster in the front end than you steve, i noticed this after lookig at your car. i always understood that increasing caster reduces the initial turn in. and that seems to me like where you are having the most issue. yours also had ten degrees active caster, mine is running five. just a thought for you. your car was faster when it was on it wheels for sure. my thinking was that your car is so aggressive withall the reactive and like no static caster from what i could see, that maybe adding in some caster cold be a good thing. worth a try anyway.

It sounds like you got a really dirty carpet. The dirt on the track is sucking the Paragon off the tire, then it builds up on the tire. Get a pro crew there to do a good deep cleaning of the rug. The rugdoctor rentals aren't good enough.

our clean up crew consists of Dumas. and I keep telling him he sucks at it. he needs to stick to driving. :)

Some of the problem could be the rubber tires from the sedans. They tend to build up a fuzz on the track which causes the 1:12 cars to have very inconsistent handling. I don't know if you have any foam sedan racing there, but you could try having their heats run right before the 1:12 heats to somewhat clean the fuzz on track.

I think you're going to have the swapping end problem running a 1S on a t-bar car regardless of your setup especially when the grip is high. The thing is you'll probably be able to fix the swapping end issue, but also sacrificing performance of the car at the same time.

I was a die-hard t-bar guy and decided to pick up a 12R5. After racing this last weekend. I'm a link car convert and amazed how easy the 12R5 was to drive and work on. If you can, I would get Keven H's setup from the recent Halloween Classic and slap it on the 12R5. You won't look back at a t-bar car...

Also, is the track strictly a paragon track or all types of additives being used? If you can get everyone to commit to a one or two it might lead to more consistent track conditions.

we only run ground effects.

What I meant is that the rug needs a shampoo. Vacuuming only will go so far. Especially Mike's, where the dirt track and carpet track are nearly back-to-back... I don't know what the situation is like out in CO, though.

SteveL,

Here's my .0001 cent idea. Try the black fronts again, sauce the whole front tire but then wipe off some of the paragon off the front outside tire after a few minutes, leaving on the paragon on the inside of the tire the normal amount of time. It might work.

Steve

dont shampoo the carpet we did that one at rc madness and we ended up having to replace the carpet best way to clean the dirt off is to use a good vacume cleaner then just run on it as much as you can or soak a towel with traction compound and drag the track..

hey guys a quick questions on the jaco yellow that keep coming off the rims on the out side edge. what do you you guys recommend to glue the foam down. I would not think of usind Ca as it would create a really heard spot in the foam might soak to much up. thanks in advance

Go to a Jaco Orange tire or just glue where the foam and tire meet on the Jaco Yellow. Then after the glue has dried, crack the glue so it's not stiff, but it's still there to help keep the tire from coming off the rim. Also, don't round the tire too much cause it will cause chunking.

Can you explain this? I always thought rounding the tire helps preventing from chunking.

Yes !

Apex thanks for the reply. for some reason orange are really hard to find around here. I have one set of yellow left though i try and glue them, and maybe they'll last long enough till the orange one avail around here.

Rounding the edge provides more side bite causing more load on the rounded edge which in turn will chunk easier.

Thats not how i understand it. on a square tire, the tire edge will literally fold under as the tire changes shape under the lateral forces, and tear the side wall, and chunk. On a rounded tire, the contact patch on the sides is lesser, and doesnt necessarily provide side bite, it eliminates the square edge from rolling under (not the right way to say it, the car and tire will roll up onto the square edge alot easier) when the car rolls up on a rounded edge, its harder to tear the side wall as there is alot more foam support and rim support (hard to explain without a diagram) and you can actually get some grip flipping without chunking anything. This is as i understand it from touring, to 1/8th onroad. Ive done it literally for years and square edge tires always chunk way way easier than a nicely rounded tire. My 12th tires, i round right to the rim. I dont leave any square side wall and my cars have plenty of traction and hardly chunk.
