    900 lb springs...wow. Why such an enormous difference in terms of front and rear spring rates? At what point does it become more cost effective to eschew the shocks and springs and just install solid steel bars?

    eschew?

    One of the front shocks failed on mine once - the shaft seized and would not move. Although it made noise when driven over bumps at low speeds, handling even in fast sharp cornering seemed unaffected.

    One of my favorite words to write (although I don't speak it, to avoid the literary nerd label). Essentially, it means to deliberately avoid using something, although I bet you already looked that up.

    Actually I looked it up about 30 years ago when I saw a bumper sticker that read "Eschew Obfuscation."

    Big difference in spring rate because the rear springs are now mounted on the rear shock perch and so this changes the geometry

    Re: CTS-V Coilovers from LG Motorsports

    NVH? I had to look that up....Noise: no increase here, Vibration: no added vibration, Harshness: they are stiffer but only in a positive way. Before they were installed I was thinking the front spring rate increase from 400 lbs/inch to 700+ lbs/inch would be quite a bit. I feel with the heavy weight of the CTSV that the 700+ lb springs are just right. The Bilstein shocks are stiffer but a perfect match with the increase spring rates. I had 60k miles on the stock shocks and they felt like there was excess oscillation up and down....now when you hit bumps, the car just soaks them up...giving you a very planted feeling. FYI, the upper shock mounts are stiffer and I installed the Creative Steel rear lower urethane shock mounts....all of this results in the shock working well instead of the stock rubber mounts. These are true coilovers front and rear, so I lowered the front 3/4" and rear 1". There is about 1 1/2" gap between top of tires and bottom edge of wheelwells. Had it corner-balanced and aligned fairly stock....front camber -.50 and rear camber -1.50, caster 6.2.

    Mtbf is about 1000 hours on track and 10000 on the street based on my rma analysis.

    Impressive considering it is only 30 hours for Penskes.

    I think you mean mttr/service interval and not Mtbf. Id be quite suprised if you had a failure at 30 hours.

    You're correct. The Penskes require rebuilding after 30 hours of operation.

    Interesting and very long read...perhaps I missed it but did these ever get put into production?

    You just need to give LG a call and drop $2700.
