adding suspension springs...question
 

hi, im new to the bit charg and i have yet to fully disassemble it.....last night i had an idea to....well... break my cheap mechanical pencil and take the spring that is used to load lead...

the spring is a good diameter and i cut them to the right size, and i KNOW they are going to fit....but the problem is...i cant seem to figure out how to open the hatch under where the struts are without breaking anything ;/

if someone has a diagram or a solution..please tell me :D
thanks in advance

I have yet to do this mod but I have some springs coming so I'll be giving it a try myself. Try this link:

I have done this to all my cars. The tricky part is cutting them to the same length, so the car is balanced. Once you take out the screw under the clear PCB cover, disassemble the front end and get to work. Always test the steering before you fully re-assemble the car, in case you need to make adjustments.

Good luck.... the link provided by billybonz has great pix

Here's another pic. with the body...

payaso, what type of pen/pencil did you use? It seems like you have to get just the right one or it will be too stiff.

that mod works really really well in my Trueno, it actually changes the handeling and works really well on rough surfaces

These springs are gold plated, and from QFM. BIG PIMPIN..
My supra has the silver plated bling bling.. Gotta love QFM.

hey...how do u guys get the steering to work after u put the springs in....?

i put perfectly fittin springs in yesterday....but the steering was bad cuz of the magnet gettin attracted to it......

how do u guys prevent the magnet from gettin attracted to the spring...?

That's impossible. If anything, it would help draw the magnet over, cause the springs are located on the sides of the car. What happened is that your springs are too stiff. The coils don't have enough power to pull the magnet if the springs are putting too much pressure on the suspention. Try cutting them shorter and see if that helps...

In the QFM website, It said that those springs were 'Tomy micro springs'.. but what are they orginally for?

thanks

my springs r not too stiff....

they r shorter than the shaft cuz im tryin to lower the chassis but still have good steering....

i dunno wats wrong wit it but until sum1 can help me im running it normal....

i change my mind
 

heh yeah....i took out my springs...i think it was a bad idea now...cuz at first they were too bouncy...and my steering was off...so i took em out...
i think im going to somehow find/make plastic springs :D or some other contraption

Bay on Aim and MTL,

I dont recommend using pen springs because we have tried that before and the tension is too stiff, and the springs are magnetically attracted which throw off steering. I believe that is what is causing your problem. We sell non-magnetic springs that are delicate enough to compress on the Bits own weight. Unfortunately we are out of stock at the moment though. Also, this isnt the easiest mod to do, so I dont recommend trying it until you are comfortable disassembling and reassembling your front end.

u act as if im a newb.....

lol............

dun worry bout the springs anymore...heh i took off my strut bar a few days ago...trying to see the difference in performance
seems the same, but with a more low profile look :D

so ur running on nothin at all................>?

umm...kinda..yeah...no springs, no struts...it has a more...lets say rigid suspension now...but i always race on smooth surfaces so its perfect

hmmmmm.............

i havent tried that yet mayb i should...........

has n e 1 tried to put like mayb rubber sleeves or sumthin on the shaft instead of springs yet.....?

if so tell me how it is.....

That's a good idea, like some fuel tubing or small rubber washers - nice hard ride but with some damping - someone needs to try this!

i was thinkin more on the line of heat srink tubing and stuff its more flexible.....

thats a good idea..but im still trying to think/find a good material or object to use...

What about a really soft foam that absorbs the shoks but inflates back just enough to get back to original?

In my opinion, I think anything rubbery or grippy like soft tubing, is going to make the steering worse. Unless you put some kind of a metal washer between it to make em smoother.
Just an opinion.

I tried to put springs on my bit and had the same problems with the stearing so here is what i did, i shaved the ribbing off of the underside of the stabilizer bar and put it on upsode down, then i shaved off equal amounts of material from each side untill i was happy with the handeling of my car

Yeah...I took my suspension set off...and the car steering and handling was horrible...the stabisus kit is a must have upgrade.

it does not matter what kind of "suspension" you have, you just need to have something so it does not riding rock bottom all the time. Unless you have springs or a stablizer, your steering will be weaker and less responsive, and sometimes will get stuck going around corners and such.

also, i think that the qfm springs would make the front wheels slide more, resulting in wider, smoother turns. Payaso or anyone who has done this successfully: how do springs compare?

The springs do make the turns a little wider, but I prefer it like this...
In my opinion, the spring mod is a must... especially if you use faster motors.. If you use the stabius, when one wheel goes up, it forces the other down, to where springs are fully independant.... I use the springs without the stabius... Springs are the way to go...

did mod didnt work
 

i put springs on my zip, didnt work, because the springs are metal they interfere with the magnets, where can i get springs that wont do this???

Re: did mod didnt work
 

Go to QFM... Their springs are treated....

Payaso is right. Non-magnetic springs are a must. Go here:

QuestForMadness.com

Do you need to put the stabilizer bar back on after you have done the spring mod? I would think that it would defeat the purpose of the springs by limiting the upward travel of the stear knuckle pin?

I use springs only... Your right when you say that it defeats the purpose
