I really don't know, but still believe the bdm is stiffer than the old bd.
but to be honest .. who cares .. this car rocks :-)

Hi Martin
I understand what you are saying I think now, The older kits the chassis was a bit softer, in fact almost every carbon chassis varies slightly in thickness and stiffness, for a big race like the worlds, Yokomo will select chassis for the team so they are all the same..
But if you buy a std BD or My Bd or a Masami bd, that was packed at the same time from the same batch of chassis they should be identical and the part number is the same
They officially do 2 chassis, but there are 3 about
BD-002MG, This is a replacement for the BD-002G, same harness but it has the 4 slots at the front removed, and a extra hole at the back for a new side post that has not been released yet.
A Masami BD or std BD packed a while ago will have the older 002G, but any packed recently will have the newer one.The 002g is now not available from Yokomo, but some shops may still have old stock
Then there is the 002GH, this is still 2.5mm thick but a harder wave so a lot stiffer
Hope this clears it all up

ok this clears it up ...
all my bdms have been from one batch.
so are the bdms of the other yoki teamdrivers in germany, this may be the reason for our cars beeing really stiff in comparison to the old bds we got I thing 1 1/4 year ago.

Here's an interesting bit on the topic of chassis stiffness.
Some of our local Xray team drivers are switching away from the US version thick carpet chassis to the thinner EU asphalt version for carpet with foam tires.
I've wondered why my 007 seems "twitchy" and unforgiving. Have we found the point of "too stiff" for the average racer?
On the other hand, my BD with the hard chassis and Bomber top deck still has a little flex and is an absolute joy to drive. Hmmmmm

My Car was a exact copy of the car I used at the Last Nat of 05 to win the Championship, At that race I had 2.5 and 0.5. It gives more steering than 3-0
Someone asked about the rear tower? The Masami one was designed for one track in Japan, Kawaba, there we ran 8 droop and 3.5mm ride height!!
So in the UK and Europe and even on carpet with a normal 5mm height rule you cant get the droop bellow 6 with the masami tower. so cant run more than 4mm ride height!!! the whole Yokomo team have only used that tower at that track, everywhere else we use the std one
#6504
there I have a little trick , in order to be able to set the droop at 3mm :-)
You can shorten the platik part in the damper to an complete hight of 2,5mm and put it back in upside down, so you are able to make the dampers about 65mm long, which gives you enough droop and rideheight if using the masami shocktower

Sorry to disagree with you again but! Cutting to insert down or even just using the new shock bodies that have no insert is a good idea, but if you run the shock 65mm long the piston runs to close to the bladder, you want to keep the piston as far from the bladder as possible, you should not run the shocks longer than 63mm

Hey Chris,
How are you?
I am trying to talk Steve into sending Duane to the DHI cup for Checkpoint representation in Europe.......
I hope he and myself can go...
Hope to see you there...
Barry
BTW tell Sam I said hello!

yes maybe there's a problem but there is no other possibility to achieve enough rideheight and and droop
by the way, you got a personal message from me

have to agree
have to agree with Chris G on the shock length.
I've had a problems with running shock a bit over 63 mm. I'm currently running 62.1. and they feel great with the Corally springs (foam tires), will have to admit that I have to cut my tires down quite a bit to make it feel right.
I would assume the Yok whites would be great for rubber tires.

Olando..
I see corally springs.... is that mine??
For the shock length, how are you guys measuring it?
from the ball insert?
Thanks,
~Ming

yeap your 33 lbs but the blacks are working great also. last weekend I used 30 lbs (silvers) they reacted great and they fit perfect..
just had a terrible day forced to use a brushed motors.
hmm, maybe I'm measuring wrong, caliper from top to bottom.
am I suppose to be measuring differently?
On a side note the Yok fits a brushless esc with plenty of space to spare.
