Lowering Z-51 with MRC

Thanks to both of you, I feel a lot more confident that lowering my C7 won't adversely effect this awesome MR setup!
Seems the system is vastly improved over the previous incarnations.

No issues . I am taking my C7 tomorrow to the Porsche local club car control clinic/autocross winter driving skills out here in Bremerton. Weather should be driving rain, gusty winds but warm at 45 degrees. May leave early in afternoon because the saints are playing our seahawks in this weather at 130p
My alignment shop also corner balanced my C7. I can take it back anytime to check the tire wear with the new setup. I plan on tracking my car 5x this season and don't want to keep switching back and forth alignment settings. my 0.02c

GM has a T1 racing suspension kit for the C6 and a T1 racing suspension kit for the C5. That should be both a lower and stiffer suspension.
But T1 is now T2 and so there will probably be a T2 racing suspension kit for the C7 in a few months.
The idea is that someone who bought the MRC would not want coilovers and so this racing suspension kit would be something that they could use

This is an old, but often asked question. If you spend much time on the threads you will see where many owners have already lowered their cars using the factory ride height adjustment bolts. According to every string I have read....and that has been many.....the owners that have lowered them also report their alignment to remain within factory specs. I am comfortable enough with what I have read that I will lower my car upon delivery and not worry about it. Did the C6 have factory lowering bolts or was it an after market solution? Two different animals!

Well...except for scraping the air dam on just about any dip in the road

We've engineered a great kit to lower the C7 a full inch and a quarter without degrading ride quality. Check it out!

I lowered my Z51 with mag ride last week all the way down on the stock bolts..
The car rides fine no pulling,
But I think I'm gonna raise it about half way back up . It actually looks a little to low for my taste.

Scraping the splitter.
I took mine down less than 1/2" up front and a little more than 1/2" in the rear. It sits perfectly now, and I thought it sat well at the as-delivered ride height.

I think for each rotation of the bolt moves the car down or up 1/8 inch...
Did you count the how many times rotated your bolts?

I recall doing 40 1/4 turns (10 full rotations) of the ratchet for the rear, but don't recall what I did up front. But don't quote me on that...I wrote it down on a box while I was doing it and didn't commit it to memory.

I know this is an old thread. Sorry for resurrecting a dead horse.
I lowered my Z51 with FE4 all the way on the stock bolts and it had no visible effect on the ride height. It's even got 7k miles on since the adjustment, so everything should be more than settled.
I know a guy with a CTS who tried to lower his and he found out that the MRC keeps a constant ride height based on a sensor pick-up. He was advised to lower the pick-up. Any body ever hear of this? It isn't mentioned in any of the forums I've read.

Thank you. I'm wondering now if mine is lower, just not enough to make a visual impact. I admit I was in a hurry and didn't take any measurements before or after.
Thanks again.
Thanks again.

Lowered mine all the way down on the stock bolts with no ill effects. An alignment was needed, it went out of spec (was recently aligned and within spec prior to lowering).
