I seem to recall him saying (possibly on the Xray forum) that he will have two cars, one with the centre mount and one without.

It should also allow the front of the chassis to flex more which should result in slightly more steering, or at least front grip.

Those 3 ways are:
  1. 2011-style:
  2. 2012-style w/o Cntr Mount Kit:
  3. 2012-style with Cntr Mount Kit:
The main reason for the change from the '11 design (front/back) to the '12 (East/West) was due to the complaints about there not being enough room to mount electronics. Others said although lap times were the same the increased 'resolution' of the steering made it easier to drive.

The new centre mount allows the servo to only mount near the centreline of the car, which ironically is where it used to be on the '11 car

How does that chassis handle? Looks a bit like the exotek chassis. What track conditions do you run On.

Funny that most of his posts are about their products, huh?

Nope! atleast 4

Fully inboard



1 servo post and servo tape, allows the chassis to flex and no "pip" to dig in

Ok, 3 official ways of mounting it then.

Really only 2 official ways on the current chassis. I've never seen anybody run the servo in the north-south fashion on the 2012. Just the stock 2 post mounting, or the optional carbon fiber top mount.

Speaking of steering, I was never happy with the fact that the stock turnbuckle between the servo saver and the steering arms was basically 100% bottomed out when I had the servo horn vertical. I also had about a 20% EPA difference in my left and right steering to get the car to turn equally. Last night at the track I started messing with the steering on my setup station.

First I rotated the servo saver a little bit, so it was angle away from the center line of the car. This increased the length of the turnbuckle. With this setup it took nearly a 60% EPA difference to get the left-right turning the same!

I then switched the other way, so the servo saver was one spline off-center, but this time tilted towards the inside of the car. This required me using a shorter turnbuckle than the stock one. With this setup I was able to reach equal left-right steering with only a 3% EPA difference.

I have mine as per kit and there's only 2% difference.
Are you sure your links are the same length etc?

Yes, the links are equal left and right with 0.5* of toe-out.

I think the problem is I could never get the servo saver to be vertical without using about 50 clicks of sub-trim. It was off one way or the other without sub-trim, no matter what spline combination I used. Now I'm using no subtrim with the servo saver spline one-spline towards the inside of the car and it's just about perfect.

Take the servo saver off, and the link from it.

Set the servo up to dead centre (without anything on it)
Now take the small spline insert (If you use one) that fits inbetween the servo saver and the servo spline. If the saver isn't vertical, rotate the spline adapter around to it's next fitting position, then try the saver on it again.
Repeat until as close to vertical as possible.

That's how I did mine and it ended up almost spot on.

Believe me, I did this and anything else I could think of. I couldn't get it vertical without a significant amount of sub-trim.
