It gives them less rebound. A more linear feel both ways. I prefer them that way myself.

I'll be trying the car out that way tomorrow and will let you guys know the results.

Hey JOLLY. Less of the old dogs and old women

I just want to clarify on what Turtlemaster has posted... is he saying that the chassis with the Part No. BD-002MG would best suit asphalt tracks that have low traction???

One more thing, i i want more steering specifically more turn-in from my BD, what changes in setup do i have to make or parts would i have to change??? If i'd use the front suspension mount part # sd-300f10 1 deg, will that help me achieve more turn in???

try hb parts or Yoki K4 C-Hubs ZS-4134 in combination with SD-202G parts in the steering. This will give you much more steering throw and therefore´give you much more steering.

the toe-out parts tend to give more steering especially in mid corner

first of all thanks for the reply...

for what specific Yokomo car do the C-Hubs ZS-4134 come with??? Do i have to do any modifications or grinding when I install them to my BD???

also, has anybody tried what Chris Grainger advised a few pages back on using a 2.5 deg. rear suspension mount and 0.5 degree rear hub carrier to achieve more steering??? can you really get more steering from changing those parts even when they're at the rear end of the car???

the c-hubs are from the old mr-4 tc car (in germany called K4). They are narrower than the kit hubs an ind combination with the steering parts from the cgm you have much more steering throw

my thoughts are with the more rear toe the quicker the car will get off center, (turn in) but with less rear toe the car will come off the corner better, i run as little rear toe as possible (until the rear gets loose). i have tried the rear toe adjustments, but it was with a 2.0 rear block. for me i couldn't really tell, i must also say that i run on a indoor pavement track where the temp doesn't very that much. i may get a little cooler with the winter weather, but it doesn't change thoughout the day. the tire most chose to run is the speedmind premounted sorex 36's. hope this helps a little.

Default rear toe

I agree..if you need to run under 2 degree rear toe try the SD plastic blocks they work rather well not as bling as the blue aluminum but will do the job.

I use to run 1 degree in the rear and the car exits the corner great.

Need some setup info:
I'll be trying the SDW arms any setup tips for them. Shave the insides down of course and the track width in the front is about 2mm shorter than with standard arms.
I will say the shock position looks great, two holes right in between the standard arms shock holes this solves a ton of problems with running foam tires.

REAR TOE> For mod we run a bit more toe, simply because we can afford the loss in straight line speed. We run the 2 degree block with 0 degree (stock) hubs for 19 turn. For nod weuse 2.5. We get 2.5 in one of 2 ways. Either with 2 degree block and 1/2 degree hubs as Chris G suggests, or with 3 degree block and 1/2 degree hubs fitted on the wrong sides (left on right side etc). We find this one works OK.

FRONT C HUBS> Use AE TC3 (not TC4) front hubs and bushes. They are almost s asraight fit. We run the 4 degree hubs with some anti dive on the arms (2mm rear and 1mm washers front - on front arms).

Plan to try lots of different things today. Will let you guys know results.

I'm about to fit a set of "worlds" arms to the from of my car. Can anybody tell me what I can expect besides a little more turn in? Anything else I should do to make the most of the change. The car has been great with graphite arms, just trying to get a little more corner speed. thanks

I'm running diff/diff with foams on carpet but thanks for the tip anyhow. I'll probably be changing back to graphite arms. The "W" arms seem to make the car a little inconsistent in the corners, may be too much flex with the plastic. I lost nearly a full lap from last week. bummer
