thanks for sharing your setup, i will give it a try.
do you think lay down front shocks would handle better than stand up?
also i m not using chassis spacer, would it make any difference?

What also helped me a lot was playing around with traction compound. I have tried applying the compound for different amounts of time, and location on the tire. And the best I have come up with so far is what I have above.

I would like to thank the entire Exotek Team and Company for their support and sponsorship for the 2011 Cups @ Da' Bowl! Awesome prizes and gifts.
My friend and I took 1st and 3rd in the Cup Modify class.
Thanks again!

Not "modify motor" per se. Maybe they should of call it "Super Stock".
I don't think any of the cars ran anything lower than a 17.5T. What makes it modify, is the tires, open speedo and some option parts (Ex: Exotek Cup, Hot Racing, etc). But 17.5T Brushless is the norm.

The stand up shocks are the one thing I haven't tried that I plan to in the future. I kinda don't want to touch the setup I have for now because what I came with before was terrible. One of the biggest things that helped the setup I have now was going to softer springs in both the front and back. When I had the hard springs (Pinks Front, Blues Back) the car was very unpredictable and would act different every time. The setup I had now the car is super easy to drive. When I went from my old setup to my current setup I picked up 3 laps in a 6 minute race. I think the reason I was able to pick up so much is because the car was so easy to drive, that I was able to focus more on the track around me and not be surprised every time I go into a corner because I had to put all my attention on my car. When I came up to slower cars I was able to look ahead and plan where I wanted to pass. Instead with my old setup I kinda have to hope for the best that the car is going to act like I think its going to. The only thing that I might want to improve on is my on power steering. It's a minor problem and only affects me in a take a corner a bit wide and I want to quickly get back into my racing line.
What also helped me a lot was playing around with traction compound. I have tried applying the compound for different amounts of time, and location on the tire. And the best I have come up with so far is what I have above.

Has anyone tried running a ball diff in both the front and back? After talking with a few more experienced racers they thought it was a little weird there is a gear diff in the front and if you were to run a gear diff most people run one in the back.

whats a good starting point on gearing with 17.5 BL motor?

Couldn't get the rear ball diff loose enough to control on power oversteer without slipping. Looks like a design issue with the metal ring gear and plastic ball cage. One diff ring is rubbing on the metal gear.
Still trying to figure out how MikeR is using the plastic gear from a Hot Bodies car.
