Regarding FFR engineers spec'ing the shocks... I have no knowledge of how that process actually worked but I'll offer this from recent experience... I have pin drive width front and rear suspension. Many owners have experienced trouble with getting proper ride height in the rear because, apparently, the shocks are not long enough. Also, the suspension bottoms with the 450# spring supplied. These setups constitute a very small percentage of FFR cars. This got a fair amount of interest on the forum recently and Jesper from FFR (their head suspension engineer), piped in to say that the rear spring rate for pin drive had been changed from 450 to 750 and that cranking an enormous amount of preload into the spring (because of the short, standard width spec shock) to get barely enough ride height was not an issue. However, they would offer the longer shocks for those that wanted to make it "easier" to get the proper ride height. Based on my experience with this, there is no way a credible person could think the shorter shocks are acceptable. And, to have the main suspension engineer admit that the springs shouldn't have been 450 but rather 750 and that the shocks should be longer really makes you question the..."diligence"... that went into some things. If you extrapolate that to things like zip ties, who spec'd what, etc. it gives a perspective on things. The car is great but there are certain things that didn't get done the way they should have.
