That's what Cavalieri was running on the track that i run on. Was just trying to get a lil more input. I'll run the same springs then. Thanks

Put the ballast back in by
the transmission , will make the car steer way more ...
*use the team weight , or up to 21 gram for the most steering ..

here is the big bore spring chart.

Thanks for both of those spring charts guys!

What tires are you using? Where are your shock mount locations? When you press the front, then rear all the way down, do they rebound at exactly the same rate? Good starting points to check...

On the team drivers setup they say to run b44 rear arms on the b4,what would that part number be. I found #9583 carbon arm for b4.and I found #9764 which is the same arm for both cars.

9764 is the b44 rear arm, 9582 is the standard b4.1 rear arm

Thank You.

so what is the difference between the arms???

9582 is softest
9764 is medium
9583 is stiffest

Can use as a tuning aid in high/low bite conditions

The problem with that chart is the word in front of (lb/in.), that being "theoretical". The mfg's ratings are only useful if you stay in one mfg's product.

In short, that chart is wrong.

Well, that's the only thing available. Until manufacturers test their springs the exact same way nothing is going to change.

Hi guys and gals...maybe

So,got my B4.1 working allright,was looking for some stick on weight last race day...But,stick ons look so cheap,and nasty...even with sharpie marker paint job...

A mate showed me these..... Even match the current trend on gold turnbuckles.
Its a pity it comes with the big 50 gram block,im only using the 4 and 6 gram squares...look awesome mounted,uber neat.
Maybe ask some of the racers at yor track if they have the kit,and arent using the square weights...

Just requires a drill,and a 3mm tap...the tap isnt required,i had 1 loaded,so i used it.

Ignore the stick on,i forgot to pull it off before the pics...

Also,do you think using the alloy screws on the front axle to secure the wheel is tempting fate,or will it be fine...i race mod,and still crash occasionally...I went to the 4/40 screws,the little ones strip to easy

Cheers....and +1 on AE loosing the blue ano.....none of it matches,it looks nasty...im voting gunmetal grey,with gold detailing,shock shafts,turnbuckles,few alloy bits here and there...no more shoddy blue

No offense, but what good is it if you know it's wrong? There is an alternative, but it requires some work:

Users can rate their own springs. Google is chock full of how to articles on how to calculate wheel rate.

That's how I figured out the chart is no good. And how I figured out a certain set of springs I received were actually two different springs (they were both marked the same, and in the same factory sealed package). Upon further inspection, the wire sizes were substantially different.

I can't believe I'm the only one who got "lucky". I can believe I'm the only one who caught it because I was looking.

Here's what you need to know (IMO)


AE Green rear 1.9
AE brown front 2.8

KY gold rear 2.5
KY white front 3.72

Losi Yellow rear 2.0
Losi orange front 2.9

Other Losi options
Losi White rear 1.8
Losi Pink rear 2.3
Losi Silver front 3.2


And now my head hurts....
