Use tall ball studs on the servo saver and the knuckle. I think I have 3/8" (10mm) on both. The steering links are now parallel with the upper arms.
Servo is mounted like in the picture.

Isn't the car made for the Airtronics SRG servo? Or is this an older kit?

Yes it's for one servo model only for the laydown. Other servos will not center right.

The only servo you can lay down flat on the chassis is the Sanwa SRG. Other servos must be mounted differently to fit under the body. The instructions show you how mount a "normal" sized 12th scale servo. I am using a low profile 1/10th scale servo in that picture, and it is held in with set screws and servo tape. Not the best looking mounting method but it works. The stock servo mounting method with a 12th scale sized servo also works very well.

Dumper did you have to lower the ball studs on the servo save with shims

Yes. I lowered them to match the upper arm angle.

So to clarify there is only ONE servo that can be in the lay down configuration? I'm shocked I cannot get anyone to answer in the only semi WTF1 thread there is here. What is the sanwa SRG? Googling that brings up a bunch of models w/ extensions (SRG-LS, BLS, BZX, etc.

Thanks
Dave

I have not seen any other servo that fits the mounting holes. And I have looked extensively.

Thank you. I also noticed that people are mounting the servos two different ways. One where the servo shaft is parallel to the ground like the manual shows and another where it is vertical. Is there a reason people are doing it one way or another? Sadly CRC hasn't replied to emails on their own product which is already making me hesitance to buy CRC.

They are all off at the Snowbirds. I know Dumper well and he usually answers quickly. I have run the servo both ways. I think the way shown in the pic is best. I currently have a Solar 658 mounted like that with 3/8 tall ball studs down on the servo saver and the same on the steering knuckle to make the links parallel to the upper arms. Almost zero bump steer and good ackermen. The inboard ball cups just clear the inner hinge pins on their sweep to give you an idea of how far forward to mount the servo.

Ahh yes. It's easy to forget how small these companies are after dealing with larger companies on a daily basis. As far as forward placement. It appears in that pic the tie rods seem to be perpendicular to the front tire, is that the goal?

Not necessarily, His do appear to be close to parallel but that car has a prototype upper hinge pin mount. It all depends on what you want the ackermann to be. I like mine to be swept back from the servo. You will see many variations if you walked thru the pits at a major race.
