What I have on my car is, aluminum shock caps, 12.5 degree aluminum front caster blocks, floating servo mount, aluminum steering rack, I only have the top part of the rack now, waiting on the bell cranks, aluminum pulley for the front gearbox with aluminum side pieces, the narrow rear belt and pulleys you mentioned already, the two 25 gram plates for extra weight, I'm using one plate under the battery, front and rear graphite shock towers, front rear and rear rear aluminum hinge pin holders, the ones for the YZ-2 fit and work great, 0 degree aluminum rear hubs and aluminum rear camber block. This should be a good starting point.

I hope you can help.

thanks
The car is pretty light out of the box, but for stock you could get all of the light bits & titanium screw kit, to lose even more weight.

The narrow rear belt would help with stock motors, after that, you only really need the rear hangers, roll bars & some springs to change set-up to suit your track.

Most of stuff people (including me) are putting on the car, isn't needed.

I'm a bit bemused this car doesn't come with roll bars .... XB4, B44, D413, ZX6 all came with at least 1 roll bar.

For those that have replaced the clicker with an aluminum pulley.. is Z4-630FC the correct inner pulley guide ? I see that Z4-630F3 is listed as the outside one and Z4-630A is the pulley itself. But Z4-630FC says center inside.

To replace the clicker you get the narrow pulley and two of these. http://www.mibosport.com/aluminum-pu...center-outside.

Sorry if this has been asked before, but YZ4 or Bmax4 for low to medium traction dirt? Likely to get bumpy by the end of the weekend.
I have both cars, but until now have only run on carpet, but have a major meet coming up on dirt. I wont get the opportunity to test both cars, so Im going to have to take a punt and just pick one and run.

Boiling the wheels for 30 minutes makes them more flexible and less likely to break.

For those running the flat arm carbon fiber shock tower and struggling with getting the ride height you want, the gullwing arm tower fixes the problem with no need for the longer shock eyelet, I am running 21mm front ride height and my shock collar is halfway down the shock body were as before it was all the way down and all i could manage was 18mm.

I got the first race in tonight with the Yz-4 . Qualified 3rd and finished 2nd . Anybody notice the front belt rubbing the motor housing? I noticed their is no inner flange on the spur pulley and it seemed to be hitting the motors casting . So I ended up putting a .5mm shim between the clicker flange and bearing to try and get the belt away from the motor . The Yz-4 is very fun to drive .
