Team Associated B6 aluminum steering rack, bellcranks, servo horn review (ASC91669, ASC91668, ASC1366)

I noticed the stock plastic steering rack and bellcranks had a lot of
slop in them, so I decided to try the aluminum rack and bellcranks.  
The aluminum pieces are a little more precise and got good reviews online.

The weight difference between the two full steering systems is 2.6 grams.

I left the plastic servo horn in my buggy, but it broke within a few packs.  I replaced it with another plastic horn, and that broke on the next pack.  So I decided to get an aluminum horn.  Associated makes two horns, one for the B5 and one for the B6.  The B6 horn is a couple of mm more forward than the B5, but you should select the one that fits your servo better.  In my case, I have a Savox 1257-TG, and it would probably fit better with a B5 horn – the B6 horn mounts it a little too far forward.  It’s not a big deal, but it’s less linear this way and the steering linkage is not quite perpendicular to the steering rack like it should be.

Overall, I find the aluminum rack to be more precise and direct.  There might be a touch more steering with the added weight as well.

Something I noticed was that my steering linkage was hitting the left upper brace when steering is turned to full right:

I had to take my dremel and notch a little clearance for it.  I’m not sure if this problem existed with the plastic rack, but without the clearance I could only get 95% throw left and right.  With the notch, I can get 105%+ steering EPA.

Overall a nice bit of kit.  The buggy feels more precise with maybe a touch more steering.  As long as I don’t start blowing out servo gears, I’ll be keeping it in.
