Today's rainy day (skipped autoX) update: The KYB's are back in the car in the rear for now. The rear sway bar is now out of the car. Was not a fan of the rear axle on turn in. Felt like the back of the car was trying to lead the front. I have always preferred my miatas without the rear sway bar and thus far I like the way the FC feels sans rear sway as well.
This feels like a more cohesive, predictable set up. I will likely run a rear sway once the car is on wider wheels and tires, but for now I'm pleased.
We also made a major upgrade to the brakes: I had a 929 master cylinder sitting ready to go for my old V8 FC, so we swapped that in along with Hawk HP+ pads all around. The car now stops like its hitting a concrete wall. So much so that I'll need a proportioning valve once we get wheels and tires swapped. Bedding these in was...interesting. Tires are now the limiting factor getting the car hauled down from speed. Really loving the pedal feel as well. Still has some of the FC dead spot at the top of its travel, but the pedal is much more progressive than before.
I'll have to get better about actually taking pictures in the future. Then again...most of you know what FC guts look like.
