Default Yz-4 VS Hbd413

How would this car compare to a d413? Easier to work on (getting diff's out) any issues with leaking diff's? Any must have upgrades?


Thanks!

Diff leaking will not be a problem.

Getting the diffs out is a lot of work though, due to the fact they are put together in a horizontal way.

The rear shocks, advantages/disadvantages of mounting them on the front of the rear arm or the back of the rear arm?

Like kempower said, the diffs can be a pain to get to, the front in particular. Your unlikely to have the time to replace oils in between rounds unless your at one of the bigger meetings. Having said that, the car otherwise is easy to work on.
And as for Yok diffs leaking, thats unheard of.

There are a few things that the shock mounting achieves, but generally, shocks on the back gives it a bit more traction in lower grip conditions. Also slows down how quickly the car reacts.

Shocks on the front, make the car react faster in turns as the weight is more forward. Gives a whisker more droop. Better for when the grip is up.

I tried mine both ways on a slimey astro track, the shocks forward were 0.5 seconds quicker on a lap, but harder to drive & slower over the run.

One other thing that it does is that it moves the location of the wing. Shocks in the back = wing further back. That definitely has an effect at high speed.

I also should have mentioned that i'm running on med to high bite indoor clay track. OCRC. Most of the setups I see are for astro, carpet or mixed track. The clay setups I see are for low traction. Being such a new car I know it will take a minute for a med to high bite clay setup. I copied a setup of a regular at the track and it's been a night and day difference in the way the car handles and drives. When I get it to where I like it, I'll post a setup sheet for it.

Also I'm full loose on all belt tensioners.
I was assembling my yz4 today and noticed the belt tension was not changing much moving the rear tensioner forward or aft on the wide belt. I installed 3mm of shims between the tensioner mount and top deck and still have plenty of room to get my shorty pack in and out. Should I adjust the tensioner all of the way forward to get the belt as loose as possible or is rearward the loosest setting? This is the stock wide belt btw as I am waiting on a backordered narrow belt kit. Right now the front belt is a bit tighter even with the top deck tensioner removed.

Don't forget about the rear tensioner on the rear belt located on the center bullhead. It can be adjusted, thus sliding up and down a tad to loosen or tighten the rear belt. Again it's Located right behind rear belts center pulley.

I'm using an Exotek one for Associated B4/5s. The holes line up pretty well.

I think I saw somewhere, someone using one from a Yok touring car, but not tried one myself.
