The manual says to screw the cups together but I don't like the angle of the servo like that, I like th servo to point straight up for straight ahead wheels. I plan to add 5mm of a gap with the new turnbuckle and the cups.

If the horn is straight up for straight ahead wheels, it will almost certainly hit the bulkhead on the rh side of the car before you achieve full left-steering throw unless you've altered the geometry in some other way as well.

They didn't arrive at the steering rack/servo mounting setup via amateur internet engineering - the steering works very well built the way it was meant to be.
I don't want to sound harsh but I've seen many attempts in-person by people to "fix" the optics of a steering setup that just "doesn't look right" and haven't seen one yet that didn't leave them with a car that then doesn't even turn the same left and right.

I use the stock supplied servo horn on a savox 1258 with no issues. Angle looks funky but works nice and smooth.

I got the idea by looking at pics of Lee Martin and Marc Reinhards EOS buggies. Maybe you're right and straight up and straight wheels won't work, I'll prove it to myself one way or another this evening

Update! The TLR aluminum horn did not work because it is too short, so full throw left to right was not possible. Threw the stock horn back on, using a slight 3mm gap, it all works nicely and nothing hits the bulkhead. Full throw both sides. The horn is still off centre but not as drastically as per the manual. I'd like to get an aluminum horn however, something in the 21-22mm centre to centre is needed.

Machined shock pistons; possibly the under battery weights. Otherwise, the car comes with a B6-sized bag of aluminum parts in the box already...

I just build a DT edition. Still all stock setup. Which piston best matches the stock ones? I was curious about tapered ones as well.
