NICE DUDE, you will enjoy it. You should do the camber plates too It allows for more aggressive alignment which REALLY improved the turn in and mid turn stability. Also more direct as you get rid of all the rubber stuff up top

just measured my 991.2 C2 on H&R and it is 26 7/8 front and 27 rear. Its low. Maybe too low, but its what Ive got!

Axle lift would be helpful... on a side note, the new C8 corvette has auto gps based axle lift, which is awesome if it works...

I have a set of used TechArt Springs I would sell for pretty cheap from my 991.1. Here's my car on the TechArt.


Dropped on Tech Art
What is this snapring adjustment on rear shock you speak of? I don't remember seeing anything like that when I did my springs. How much more can you sneak out of it? Intrigued, I'll have to crawl under there and look.

Second the motion for the camber plates. Alignment is the name of the game to maximize benefit from any upgrade.

if you look under the the spring perch on the stock rear shock, you will see machined slits and DIRECTLY underneath the spring perch is a snap ring that you can lower, which in turn lets the spring perch fall so you can lower the rear ride height.

I will get them at some point. Need to cool it on mod spending for a bit, spent a lot in the 2 months I have had the car. Going to install coils with OEM mounts, and maybe upgrade to aftermarket in the spring or something.

Ya I did notice the notches on the shock and wondered what they were for. Didn't look close enough I guess. So how is it adjusted? Is there a snapring inside the spring perch?

What notch are guys using for the Techarts? The manual says either third or fourth from top. I'm not actually sure which one mine is at but I'll check when I get home. How difficult is it to change to the next notch? If I move down one will it require a re-alignment?

I want to know this also. I bet this is the reason some cars on springs look raked and others don't!
