My track is very tight and is asphalt, it has one very very tight 'S' hair pin. Here is my setup for stock, the one that is wearing the hell out of inner tires all around. (But I have the most steering this way.)

http://forum.teamxray.com/xform/inde...3&setup=t2_007
^-Theres the setup

I have a ton of steering in the corners and I am the fastest by far with this setup but man its eating my tires slap up! Help someone.

One last thing maybe im just not understanding what does what, could someone explain to me what the roll center quick positions do again? Putting shimms on the other end?

Thanks mates!

Tyler, quick roll center adjusters are one way of making a roll center change to your car. The other two are shims on the upper-outer link, and different hingepin holders (lower-inner). To see how they work, and what each position gets you, you need to know how to determine the roll center of a suspension setup. It shows you in the T2 setup book. That book also has tables that show what outer shims and inner quick roll center adjustments result in.

To fully understand everything about roll centers takes a lot of research and study (and a degree in physics and/or engineering helps, too). Resources include books on vehicle dynamics, and a few websites. To get the books you pretty much need access to an engineering library. Here are a couple pretty good websites:

It isn't simple stuff. That's why the tables in the Setup book are very worthwhile to keep handy and even memorize.

Looking at your setup, you've done everything right to get even tire wear. I've never used CS27s, but it certainly sounds like that type of wear is simply inevitable. Try RP30s.

You could also try moving your rear upper outer hub linkage position to the outer one ("2" on the setup sheet), and this should lower your camber gain. I don't guarantee success, though.

Another one would be to lower your roll stiffness even more. Apparently this helps tire wear. Lower roll stiffness by running softer springs, moving lower shock mounts inwards, and losing outer-upper shims.

Dragging a front tire is potentially causing that tire wear. But, you say you have high corner speed. You can try more and less ackerman to alter tire dragging. A touch of front toe-out is similar in effect.

No, I'm not just boosting my postcount.

I'm wondering, how are you running the outer standoffs on the EU topdeck? I thought that deck only had the inner standoff option.

WHOOPS!

Your right, there one lower in the front. I just knew that they were the furthest out on the front deck, so I clicked the furthest. Thanks for all the help man. I really dont know what im doing I just try stuff and look at my times, it seems in doing it right but my tires are killing!

The reason I run CS27's is becuase I cant get RP's to hook up, and I havent ever doped my tires! Do you sauce your tires every time you run?

heh, don't take tire advice from me. I've ran rubber tires a grand total of three times, ever. My technique is to hit them with Niftech, and hopefully I remembered before hearing the 'two minutes left.' It's a far cry from the guys who use a proper compound and tire warmers for the same length of time every time.

At the C in Frederick MD ( indoor asphalt ) we run rubber tires ( 30s and 32s ) and at the Sedan challenge last weekend the most common used tire sauce was Paragon with tire warmers.. The cars hit the track and the tires was dialed in....

Those RP27's are known to wear away on the inner part of the wheel, we run Rubber Tires year round up here, I would suggest some Team Sorex 32R or 36R Premounts, they wear alot better than those CS27's, and you can be aggressive with your "dopeing". If you don't have tire warmers that Paragon Ground Effects (black can with pink lettering) is the best stuff you can use on your tires. If you can't get Sorex Premounts, then I would go with RP30's

Is the KO 2143 digital servo, a good servo for the 007?
