Check for setups from the KO Grand Prix. It's an indoor track, but the track is very very very high grip asphalt.

I think this might be useful in understanding roll.

Lateral load transfer is given by..

(weight of that end of car x CG height x Lateral acceleration) / track width

how much you roll will also depend upon the total roll couple you have which includes roll center, anti roll bars, springs, shock oil etc. High roll center (less roll) is better for hi traction tracks, low roll center (more roll) for
low traction. Tuning from wheel offsets is easy and time effecient, you dont have to put into a setup system. It may change the wheel base slightly, and the toe as well( it didnt change my cars toe). During practice and race, I prefer changing trackwidth from wheel offsets rather than the suspension holders shim, because the latter will change shock position, thus possibly ride height, camber, downstop, roll center. Nevertheless, the latter is still a good tuning option XRAY has, which a lot of non-xray drivers want, the more tuning options the more possibility for fine tuning. Tuning trackwidth from suspension holders is more of a primary, permanent, long term tuning, whilst offset is more of a secondary, short term, quick and easy adjustment.
hope that helps.

Is there a T3 setup that would be a good starting point for very high grip asphault like the Colisium in Frederick MD?

Thanks

I would start with the KO Race set up. but i would incorporate the low roll centers all around and front shock set up (2hole 500) from the most recent set ups.

that is most likely where i will start this outdoor season.

Thanks!

Out of interest, why start with the lower roll centres as opposed to kit, is that due to lower grip levels?

Hi, this is not going to make much sence, but you asked LOL.

for me the 11 car has a lot of natural roll. when i first started setting the car up i tried a ton of things to keep it from rolling so much, but everything that i did just made the car harder to drive and it still rolled a lot anyways. finally i just figured that if the car wants to roll a lot that i may as well just let it do so even more. so i put on low roll centers all the way around and it was definately easier to drive for me and just as fast. Then to make the car roll equally front and rear i made the wheel hexs change and went to the two hole front piston and that is how i got to the current set up.

i think for carpet it is good, for asphalt i would most likely run a similar set up but with standard hexs for better steering.

Hi Paul, I can't seem to find any setups from the KO race do you have a link? Is this under your name or someone else? And just to confirm, are you saying you would run this on carpet as well as a starting setup?

Are you still using the original inner rc adjusters or have you started to use the new version yet?

Thanks

I thought i posted my set up from west coast but i guess i did not.
For carpet i would start with my cleveland set up, http://forum.teamxray.com/xform/inde...&setup=t3_2011

For asphalt i am going to start with the same set up but with these changes.
1mm shorter rear wheelbase, long "bulkhead" front camber link, standard hexs, 0deg outboard and 3deg inboard rear toe.

what do you mean by "rc adjusters"?

Thanks!

Those inner roll center adjusters that use shims instead of the shock tower for attachment.

Hi Paul. I hope this hasnt been asked before.
But...do you use the speed in and speed out(TN, RN) setting on your transmitter for the steering servo?
And if so how do you set it up in combo with the expo?

Paul, have you ever measured the corner weights of your car, and more importantly, what is the weight distribution front to rear.
