CSG Spec Tein Flex A Owners Thread

CSG Flex A is Corkscrew tested during the recently concluded Round 6 of 86Cup

So, in my last post I touched on how Grid Life just didn’t go well for me. Well, a week later and I got to head back to the same track in “full” configuration; Autobahn Country Club in Joliet, IL. This time the weather and driver were in much better condition!

After some thoughts I reduced stiffness up front to 6 clicks and kept the rear at 7. Both counted from stiff. The result? Amazing. Compliance on the car went way up and it just felt so right. This was the sweet spot I had been looking for on this track and it led to me running consistently faster and more aggressive laps. I even posted my best lap ever on this circuit at 3:04! Precious best was 3:07 a year ago on RE71 with stock suspension and a stiffer front bar. This time I was on the GT Radial SX2. By all accounts a “slower” tire. Feeling myself just get more and more comfortable with each lap just blasted my confidence into the sky. It was amazing.

Videos below for the curious.

I know I still need more work as a driver, but this is the best I’ve ever done thus far.

Definitely seems like 6-8 is a great sweet spot for these on most tracks. Mike, is there a good way to tell if you’re running too soft of dampening and could benefit from going stiffer?

Yes, but you'd need a bit of seat time to recognize when the car is underdamped. It'll become easier once you go through the range of damping.

For now, keep upping the damping until you start getting hopping or a loss of grip where you did not previously. This will vary by car setup and track conditions.

Once you get that loss of traction, back off the setting 1 or 2 clicks. Unlike most coilovers in this price range, each individual click is meaningful.

what is an expected time/miles between full rebuild?
is given the cost of FLA, rebuild a viable option anyways?

Depends on your driving conditions and how you treat them. It could be as short as 45k miles, or as long as 90 miles.

Rebuild is totally a viable option. These are not throwaway dampers.

Thx for info. My '17 PP dampers lasted about 25k (s)miles. I mean they still work but that wonderful feel of precise rebound holding suspension in stable position and releasing slowly is gone. My driving style does not promote longevity ...

Sweet picture, but I wonder why rear is way more compressed here. Because your run 6ksquere, it is rear is too soft?

Has anyone compared these to a RCE yellow/B6 Bilstein combo? Or is a better comparison the Bilstein B8 as the Tein Flex A might have reduced droop travel?

The CSG Flex A has been preferred over shock replacement and lowering spring combos.

I believe it's due to the resultant motion ration from the multi-link rear suspension. If the springs are 6k square, the rear spring rate is closer to 4.5k
May also be caused by throttle

Yeah you pretty much go full throttle from the top of the corkscrew until the next turn in, so I'd bet it's at least partly due to acceleration.

Edit: That is coming out of the corkscrew at Laguna Seca right?

That's coming out of the corkscrew; the car is seeing almost 2G there, vertically, momentarily.
