Looking good Rod. I'm more wimpy now than I've ever been in my life, and eventually had to modify a Prius EPAS column to give me what I need with the Porsche rack. Great rack, but with its low ratio (high effort), a 13"steering wheel, and two shoulder surgeries, I had to figure something else out. End results were really good, and now wished I'd done it sooner.

Last note since there is so much similarity between our projects, the design of these racks allows a lot of flexibility in inserting spacers on the ends of the rack to eliminate bump steer. I think I had to add something on the order of around 3 to 4 inches to each sided to accomplish this (basically a 1" tube with a 16mm stud in the end that screwed into the rack ends. The outside then was fitted to the need (which was clevises for rod ends).

I got the rest of my custom titanium for my exhaust

Pictures? I'm just now trying figure that out. I have a prius rack too and I'm using the column also to keep a bunch of switches off the dash and close. I will have some on the steering wheel also.

Rod, nice work and you are making rapid progress. Can you tell me a little about the Prius steering parts or point me in the direction where I can read further? I see you have selected the top of the line QA1 shock package, I may end up with those myself as continue to develop the ride quality of my car.

What is the M6BGT you mention? Details?

Thanks

I used a 2008 Prius EPAS. The default fail-safe mode doesn't require anything other than 12VDC, and is plenty of assist, with no additional control boxes, sensor inputs, or anything. I had to shorten mine in order to fit under the dash, which was a fair amount of work, but it all came together nicely. I had to make the Prius column as short as the 930 column, so it's now about 1/2 as long as it was from the salvage yard.


Trial fit, and looking for a place to put the Prius controller. When finished, in the default fail-safe mode (no sensors, just 12VDC only), it draws about 22 maximum amps at lock. It added a few more pounds to the car, but well, well worth it.
 
Rod, just a question and a comment , what rack is that thanks? and your front upper arms should have a connection or brace between to prevent them moving backwards under braking as there is a heavy load trying to twist those ends where they bolt onto the upright. Not meant as a criticism.

Russell, I believe that is a 911 or 930 rack (not sure of the difference between the two), and it's the same one I use. Very quick turn ratio though, so...

I have a m6gt body. I'll have to make frame for that one.
