Pull rod suspension! Nice...I thought it might be that from the early pics. Do the ball studs slide in the lever arm or is there a small link in there that we can't see?
For caster are you going to make different c-hubs at pre-set angles?
Edit: Now that I'm looking at it on my desktop instead of my tablet I can see the pics more clearly and see where the ball stud will slide in the cantilever

I am also going to be adding new holes on the arms where the up travel screw and ballstud mount. I am going to allow for them to be swapped for location. This will allow you to adjust leverage points. The further the ballstud is from the pivot of the cantilever, the softer the spring rate. This way you will have 2 spring rate options per set of springs with that now being 6 spring rates instead of 3.

If you could add shims under the ballstud on the a-arms, wouldn't that also make the spring effect harder ? You would then just need to shim the pivoting part accordingly toward the center of the car, or maybe even not. I guess with such a short lever, adding 0,5 mm or 1mm under the ball stud would significantly make the spring effect harder. Anyway, super cool front end. It was about time someone released a front end with double a-arms and real dampening on a pan-car ( the exception being the recent yokomo, but I'm not sure of how the monoshock works exactly).

Jason, this new car looks awesome so far!! Love the pull-rod front suspension!!
You should do an F1 car version of this car next...I bet it would be awesome!!

Congratulations Jason on what is a genuine innovation for the class.
I'm not a BMI driver* but I'm sure this car will generate some interest. The guys who run the 12R in Australia are pretty passionate about the marque. And I think here your car has even more potential than perhaps in the US or the UK because we race on tarmac and rough finished concrete (as well as carpet) on unprepared surfaces. Basically, tracks can be rough, and grip low and this is where the level of adjustment and improved damping at the front can be a significant advantage.
* I actually have a 12th design project of my own.

Im ok with the fact that I am not going to saturate the market with these cars. I am not able to travel around the world promoting it. I decided to offer the most exotic, high performance car i could dream up and this is what i have come up with.
Thank you guys for all the support. It is nice that even guys who wont run this car can appreciate what i am trying to accomplish. You are a good bunch of guys.
