Got my Xida ACEs a little earlier than expected, got them installed yesterday and aligned the car today. 300/200 rates, didn't have a stock front sway so the RB tubular bar will have to stay until I can get one.
So far, I am pretty impressed. I've had a few different setups on Acamas, most recently a 600/350 MSM Bilstein setup that I felt was underdamped, and a 9/6kg setup with some Taiwanese shocks we were evaluating which was better than the MSM Bilsteins but still slightly underdamped. My initial impression is that 300/200 might be too far in the other direction, especially given this car's setup (~2500lbs, 300whp/270wtq, 245 RS4s on 15x9s), but the ride quality is pretty incredible. I will give it a few weeks to adjust, but my inclination is that I would prefer something slightly stiffer, like 450/300, even if it meant a small hit in ride quality. In a 2200lb car the 300/200 would probably work better, but Acamas is very porky. Ride height was ~5.8F ~6R, I need to check where it settled to after the drive to/from alignment.
The remote has four separate adjustments, each with a range of 1 (full soft) to 5 (full stiff). It has static rebound adjustment for front and rear, a pitch adjustment which stiffens based on accel/decel inputs, and a roll adjustment which stiffens based on g-force input. Currently have the shocks set to 3F/2R static, 4 pitch, 4 roll. On flat, level highway, I can back the static settings off to 2/2 or 2/1 to let it float a little more, but it feels too soft to me around town if I go lower than 3/2. I don't think I've really experienced the full potential of the ACE valve with the driving I've done so far, but it feels much tighter in transitions and under full power than I would expect it to given the spring rates. A car which spins 2nd all the time and 3rd at night should probably feel like a sloppy mess with 200# rear springs, but it definitely doesn't.
It will be at MRLS for test rides.

Working out the final details before I do my big-power E85 tune. Installed an AEM 3.5bar MAP sensor today, doing a little road tuning at current boost levels before I hit the dyno sometime next week. If I don't hit 400whp it's because something broke

The only thing I can't come up with is a logical purpose for that package to exist.

Billet caps? Why no push to market?
I'm jealous of all that spool. There's something clearly flawed with my setup when looking at everyone's 6758 plots. You're making 20% more power by 4k. No slouch!!
I also don't think my car can handle more right now. But that's a beautiful climbing curve.
