If I remember correctly, the sound was similar to what I get when driving over a rough lateral ridge/pothole on a highway, i.e. just a hard boom.



Checked, everything's fine.

Speaking of endlinks, is that expected that I'm rubbing a hole in the frame with my end link at full lock? This is camber maxed out on the top hats, measured at -3.1.
Any workarounds other than dialing the camber off?
It's possible, although not everyone has that issue, due to manufacturing differences. You could use the SPL endlinks to gain some clearance, or use crash/camber bolts to pull the damper body out and further adjust with camber plates.

What ride height are you set to?

The endlink clearance issue is fairly common on our cars when running a lot of camber through camber plates. I had this issue with my stock endlinks. With the strut pushed all the way in for camber, there's little room with the inner fender for the endlink to move. The contact looks somewhat minor, so just about any lower profile endlink will fix it.



I use RacerX as of recently when I replaced my Megan endlinks(replaced while troubleshooting a separate issue). I have plenty of clearance with camber maxed to -3.2*.

Got it, thanks! Those RacerX endlinks look good too.

See the photo, I'd say about two fingers between the tire and the arches in the front.
The wheel/tires are 17x9 +37 Titan 7 T-S5 and 245/40R17 GT Radial SX2s.

What's the minimum drop with these installed? I'm very interested, but my apartment complex also has some gnarly speed bumps. How close can you get to stock ride height?

Also, ^ Those Titan7 wheels look amazing. I'm glad I found out about those.

there is quite a bit of threadding on it im willing to bet you can actually run higher than stock

According to FTSpeed, the non-CSG TEIN Flex A have these specs:
Base Ride Height Drop: Front -1.2 inches, Rear -1.2 inches
Max Low / Hi: Front -2.3 inches to 0 inches, -3.0 inches to 0.6 inches
Recommended Low / Hi: Front -1.6 inches to -0.8 inches, Rear -1.6 inches to -0.8 inches

I believe CSG Spec only differs in the valving of the dampers, not the springs?

Thanks, I could say exactly the same when I found about them myself! It was hard to find any fitment info on those at the time, glad I was able to spread the word.

Just to close the loop here, this weekend I tried this idea and it was successful!
Thanks to @AngelGT86Racer for sanity-checking my ideas before I implemented them!

What I did was I jacked the front of the car, measured the distance between the top of the tire and the top of the fender arch. On the front right it was 75mm, and on the front left it was something like 82mm.
I then took off the wheels and measured the A and B lengths of the assemblies and compared them to the values recommended in the installation instructions.
The "B" measurement (distance between the top of the damper body and the bottom collar) on the front left was ~2.5mm longer than recommended — so clearly I was running into the HBS more frequently than intended.
I've added 3 turns of preload (6mm, assuming 2mm thread pitch) and then shortened the damper body by 3 turns as well.

As a result, now my droop travel is the same left vs right (75mm or 3"), without changing the ride height under load.
Assuming equal total suspension travel, I now also have the same amount of compression travel left vs right.
To the best of my knowledge, this is really what damper body length adjustments are about — fine-tuning the compression/droop travel.

Then I went to test drive it, and confirmed that the ride feels a lot less harsh on the highway.
Haven't noticed any rubbing while spirited driving in the mountains, but will also monitor that at my next autoX or track day.

Will also check the amount of droop in the rear some day.

Thanks for your help. Buying both as soon as I finish being laid off because of god damned global pandemics.

It was a little odd that they initially sold them only in a size that doesn't really fit on the car, but I'm going to go with the 17x9s too.

We just noticed the little brown option on the spring. Did you get a chance to pull the brown piece off the spring? If you haven't done so, please do so before you drive around in it. Thank you!

Umm, I've installed the coilovers in September 2019 and was driving like that since then. Always thought the brown thing was a spring isolator...
You're saying I remove them?

Installing mine now and wondering the same. Are the brown plastic bits supposed to be removed while in use?
