Not as many wide sweeping changes made this year, got it aligned, still playing with the rear coilover height though. Turned the coils up but the last 1/2" didn't even raise the height. It's about even or maybe even 1/4" lower in the rear than front, front I like right where it's at, want to bump up the rear at least 1/2" more. Contacted Ridetech, the solution they suggested I didn't even think was an option, changing the shock ends. They have different lengths, bought ones that are 1" longer. This will make dialing in the height much easier. Just replaced them and am in the middle of setting the height.

Also removed the stock exhaust system and put on a gutted MCSS cat, cheap new Walker MCSS intermediate pipe and mufflers and some 442 style tail pipes that are nice pieces in 2.5" diameter with some adapter fittings to mate them up. Got the tail pipes to clear things barely and look ok. Pretty quiet exhaust which is ok with me.

The car still isn't getting in closed loop I believe and the ECM isn't connected possibly, the converter isn't locking up and my mpg is horrible at 11, starts and runs fine, doesn't seem that rich but something is clearly off. Speedo is fairly accurate so I don't think that's an issue. Almost all city driving and no lockup isn't helping but should be well into the teens I'd think. Next up is addressing the CCC wiring and how it mates up under the dash again.

Did pick up an L92 with 107k on it in May as well, price I couldn't pass up, so it sits on a stand for now.
