Soft suspension settings only cause traction rolling when your droop is too high... Balance is the key here... Too stiff a roll bar is covering setup errors elsewhere... With the Awesomatix's lower Center of gravity compared to other cars, you'll need to set roll Center even lower than other cars so you won't get the jacking effect that is caused by the roll Center being in the same position as the CG... Therefore, a very high roll Center will seem great to a point, and if you want better Performance , you will need to go to an extremely low roll Center and stiff springs....

By stiff springs, I meant stiffer than the ones you're using now.
Also, short links raises the roll Center vs long links....
Lowering the CG might seem beneficial, but it is only true when the roll Center is also lowered to keep the leverage....

Our spec tire at our club is the sweep QTS spec tire ( 32 ) which are very similar to the team powers tires ( 32 as well ) used at Time Zone II GP.
Now it makes more sense! 28's !!


If you have "setup stands" try the shorter and longer camber links on the bench. Press car through full travel and note how camber progresses. Write down total camber gain and how quickly camber changes. Having too little camber can cause the outside edge of tire to take the initial load too quickly, causing the corner entry "pressure spike" ( as Paul Lemieux has explained ) which leads to a traction roll. After observing both long and short camber gain on the bench I'd try both short and long camber links on the track and note what is successful :-). I'm curious what you find. Again, I'm no authority on the subject , so your results are interesting to me and hopefully everyone else!

Edit : to somewhat address your question: Generally changes to the lower A-Arm are more dramatic for roll center adjustment whereas camber link length adjustment has more effect on camber gain, but it effects roll center too since it is all intertwined ! Obviously, its easier to change camber links, so I'd start there... but since you are not saucing any of the fronts it may take more severe changes !

Btw, One thing , if you hadnt already , always check your set of tires to ensure they have perfect glue seams ! No point chasing your tail when it's just a bad tire seam !! I've done that once too many ...

Cheers,

Also , I want to point out that I was referring to the static roll Center(at rest), not dynamic....

Has anyone experienced wobbly spur gear once installed, if so, is this an issue?

I usually hold the spur gear when tightening the spur gear nut. Not sure whether this distorts the gear. Are we supposed to tighten the nut without touching the spur gear?

Appreciate everyone's earlier advise.

Thanks!

The spur gear mount has guides that protrude from it that should engage into corresponding holes of the spur gear. Make sure that the two are firmly seated. I use a open box end wrench to tighten the spur.

There have only been a couple of spur gears that were too thin that had excess play. I have had good success with PRS, Kimbourgh and Xenon.

OK found the problem...thanks!

open box? is this a mechanics slang term?

open end wrench is what was meant.

I've a problem with spool axle AT03 in my new A700L

the gear has disengaged the spool, it spins freely over spool axle...after about two months of life (three races and some tests...)

has anybody the same problem? maybe a production mistake?

in one year with old A700 I hadn't a similar problem...and the spool axle wasn't replaced in the entire life of the car...

There is the good method of AT03 reparing :

You should pull the crown steel gear off the aluminium wheel of AT03.
Then please clean all contact surfaces on the wheel and gear with good cleaner-degreaser.
Next apply a good retaining compound (Loctite 601, 603, 638, 640, 648 or analogs) and press the gear on the wheel full way untill stop.
The further heating ( to 60-80 deg) will make the hardening of the compound faster.
