Go ahead and start protesting every ND in CS that is lower than OE and running -2.5* of camber and is completely legal. I'll wait here and enjoy my popcorn Sent from my iPhone using Tapatalk

NDs are double wishbone....yeah not sure what the NDs have to do with the front MacPherson struts and camber gain, but I'm sure you do |

Struts will hardly gain any camber if any from lowering. Typically .1 or so but not half a degree.

Not all MacPherson struts are exactly the same. Ours do gain a tiny bit of camber under compression (up to a point, beyond which it will stop gaining and actually start losing IIRC).
Anyways, if you want to protest someone, you'll have to show they didn't install the washer correctly or you're gonna need a great pair of calipers. Given that Koni have admitted to their issue and provided a fix, you've got a pretty high bar to clear to show noncompliance. |

Shock degassing alone will not net you -0.4 to -0.6 alone. To get that amount of extra camber something has to be off. Not surprised that folks with Koni strut replacements are up in arms. Many owners claimed ignorance about the illegality of those struts when the source of the extra camber gained was plain as day! Here we are again, people with the Koni washers are claiming extra camber. Here we are again, Koni people are up in arms claiming that there must be some sort of "Koni engineering" miracle that nets more legal camber....All while not one Koni strut owner has posted measurements of the corrective washer. My guess would be the either the washer is too small and thus provides wiggle room (thus misaligning the center of the mount hole and resulting extra camber). Think about folks. The OEM crash bolt is only 2mm smaller in diameter than original. Simplistically speaking, that means it provides 1mm of extra outboard or inboard adjustment, which typically nets about 0.5 degree of camber adjustment. To get enough extra camber to achieve -1.8 or more I would imagine that you would need about extra 0.5mm or more of wiggle room. While witch hunting after for 0.1-0.2mm of variance might be unreasonable, looking for half a mil or more is much easier. Even harbor freight calipers can handle that |

The only thing you'll need to readjust is camber, which is just pushing the strut inwards as much as possible before torquing down that top bolt. Just get that useless WWRB driver we both know to help you. And I just saved you $120. You're welcome

So my understanding of that would then be that there's possibly a variance in crash bolts, a variance in the bolt holes on the cars, and some measurable change from what springs are in use. Someone please feel free to correct me if I'm wrong.

There is also a possibility that the stepped washer that Koni supplies wears or loosens, or if paint around the strut hole broke/wore off to give more play. You could also have a difference in alignment racks. If digital laser type, they do need to be calibrated. You're talking a tenth or two of variance though...not half a degree or more. |

The ND is a different suspension that nets a ridiculous amount of camber and ride height from the Konis. It's what it is.
If I remember right, we had a wheels off impound at Nationals in 2015, I believe it was because of the camber question on our cars and the reason Koni corrected their full body shocks before the 2016 season (my timing might be off). There was no protest that year, but I think it contributed to how well Koni drivers did in 2015 vs. after 2015 when the Koni correction came out. How much did it contribute? It was somewhere in the range of not at all to barely within noise. I remember before the spacer, cars easily had -2.0-2.3 up front. I can believe -1.7, but if it's still at -2.0 with Koni's spacer, I'd be suspicious. Either way, I won't be leading any protests unless it's to get the ND moved to B-Street. If someone wants to protest camber on a street FR-S/BRZ, I think they're going to have a pretty tough time winning the protest unless it's something extremely blatant. |

So much fun. No power steering, so plenty of feedback but requires plenty of effort in tight corners and counter steering. The car in it's current form loves to rotate when lifting or braking but will immediately hook up when you get back on the gas. I'm still learning to trust it, because at first, it felt like the car wanted to murder you with the back end immediately coming around when you lift and steer at the same time... getting back on the gas early and trusting it is incredibly rewarding.
I have this wild (probably stupid) dream of putting Hoosiers on the car and trying out SSP after nationals. Video from last Saturday https://www.instagram.com/p/BU5I-ZJhY0P/
