I softened the rear springs from white to yellow, lowered the rear roll center from the middle holes to the bottom holes, moved the shocks in one hole at the top in the rear, and then ran out of races to keep on trying stuff. These changes were made one at a time between each race. It still had a little oversteer coming out of the corners, next time I'm going to loosen the rear diff up a little bit and see if that helps. I run on outdoor asphalt and it was hot, track temps near 140 degrees .

I had the same problem a month ago and tried all of the same options you've listed. Try increasing your front droop (REDUCING front downstop) by 1mm and decrease your rear droop by 1mm. This worked for me when all else failed. I was able to stand the rear shocks back up one hole for faster corner speeds in the sweepers once I made this change.

It helped me stay right on the tail of the TQ and 2nd runner up at the end of the first lap after starting last in the A. But unfortunately I had my throttle trimmed too high at neutral for late braking once the tires came up to temp and they started pushing harder and pulled away. I still managed to stay six seconds behind them with 30 secs to go, but then my old batt pack gave up and I barely crossed the line two laps later for fourth.

And I so wanted to bring a trophy home to my 4yr old son.

I didnt use any extra parts, just the parts that came with the shocks. You will have to get some nuts to bolt the top ball studs to the shock tower but thats it. My tam dampers came with gold ball studs.

i had that problem once for a while and changed alot of things but none of them really got rid of it totally, what i finally did and it cured it was running the front of the rear arms lower than the rear,i think its posative anti dive

Yep, I used this rear arm setting (pro-squat) recently while testing the new BMI chassis in "stiff" mode with standoffs on low grip asphalt and it worked very well to give me quicker turn-in steering as well as a planted rear end once the gas was applied. And I didn't have to change my preferred droop settings (1.5mm in front & 3.5mm in rear) as I had before.

Talking BEST UP GRADE

Hey all

If anyone is looking for the best up grade they can get for the 05 check out the BMI chasie kit. It comes with the new redesigned chasie with the batteries moved in and forward ,adjustable motor mount, battery starp, upper deck has stand offs so you can adjust the flex, and frt and rear shock towers with more adjusting holes for finer tuning. more info www.bmiracing.com

or go to the BMI thread

Hey all,

I need an answer fast please

Can you guys use either 3/32" (0.093") or 2.5mm (0.098") diff balls in your Xray diffs? ANy probelsm assciated with using either one? IN other words-if you use 3/32" does the diff rings touch the pulley or if you use 2.5mm balls-do the balls bind in the pulley?

Thanks,
Ray
