Johnny I'm convinced that the parts in Tamiya 53574 are identical!

I got mine from ebay, should be getting them next week.

For the shocks being stiffer, did you put the same piston size and oil? the TRFs i THINK have a smaller can, so it could explain why it's stiffer, drop down one size oil weight.

Ran the car yesterday, if it wasn't for my ESC having problems, i would have been able to run it a lot longer, as it is, i barely used 1 pack, with help from a regular, we were able to get the car pretty dialed. We played with the roll center in the front, extended the front top arms to the inner hole, and raised it by 1mm, it actually help keep the front more planted as well. The car is great out of the box.

Is there anywhere i can read about how to setup the car? Not the basics, more the details in Roll Center changes, kick up, caster, etc

I've used the equivalent piston, the Yok ones are much thicker so don't fit the shaft anyway.
The o-rings were quite old so I've changed them and the car feels much more normal now, can't wait to try it tomorrow.

Those changes are covered in the XXXMain setup guide.

I need a lot more steering. The car is way too stable. What can I do to get the front to react quicker and also get more rotation in the middle of the corner?

Narrow front hubs (4.5mm)
front inboard toe
lay down front shocks one hole
softer front spring
more rear droop

You could also use 4degree caster blocks.

Yeah thanks guys. I just received the 44.2 block in the mail today. I ran the stock setup and ended up running blue springs front and rear.
Also lowered the front shocks and less rear toe but its still too stuck. The graphite arms helped a little with the sharpness but the issue is more fundamental than that.
Where can i get 4 deg. C hubs?


In the setup sheets on petit rc, they list the droop as distance from ground to what? The bottom of the arm or the hingpin ?

There is a space for both measurements on the setup sheet.

If you look just above where the measurement is given it'll say "Arm" or "Pin".

You can also move your roll center, i lengthened my top links, and moved the ball to the inner hole, it gave me more aggressive steering in a turn.

umm....does everyone agree with this? not saying that you are wrong... but from my previous testing it always seems to me like shorter camber links make the car more responsive. hence, more initial steering.

I believe yes, shorter links react faster.

From testing other cars, I would agree with both of the things you've said.
Running shorter links all round makes the car react faster, but runnin the front longer than the rear gives more steering.

I haven't tried it on the BD7 yet, but I'd expect the same to happen.

What ackerman are you running? Try 1.5mm. Also try a heavier rear gear diff and 2.5d rear toe. The car comes with 4d C-hubs, 6d wont help your issue.
