Did you shorten the inside ring on one side of the coupler? The Eibach couplers I have inside rings that extended about 1/4" from the center of the coupler on both sides, but the coupler in your picture looks shorter on the helper spring side.

 

I didn't shorten the inner ring. The set I received had about a 1/4" ring on one side of the flange and 1/8" ring on the other side. The 1/8" side just barely gave me the clearance I needed to allow the helper spring to fully bind. Though, I think I have one of them installed incorrectly because one of the helpers isn't fully collapsed. I'll have to take a look at it tonight.

 

Ah, weird. The Eibach couplers I bought recently have 1/4" rings on both sides of the flange and would require either shortening on one side or switching to something like the more expensive Genesis couplers (have the ring on the outside of the helper spring side) to work with the Hyperco helpers.

New dynos both bad

 

Quoted from something I was reading recently

Conclusion: Whether you think my way or not, ultimately does not matter. As a team, you should do what you think is best for your type of racing at your track. If zero roll and running on bump rubbers or in coil bind makes you happy, then by all means, go for it. I have always believed that most racers are not totally happy unless they are making changes and experimenting, or just plain being a scientist in our own little way in our secluded little world.

If you can't be happy at what you do, then quit. If you must experiment, and we know you must, I hope that we have provided enough useful information so that you can either find more success or at least know why you didn't. It's all in the knowing either way.

 

I'm sure u learned quite a bit doing that. It will make future successful dynos all the more sweet.

 

I didn't do any of what he mentioned if that's what you meant when you said "by doing that"

BTW are you still on the stock Bilsteins? when the next auto x that you'll be at?

 

Correct me if I'm wrong but i thought u were doing your own valving work now. That is what I meant by "doing that".

I'm still on stock Bilsteins right now. I've recently bought the new springs I'm gonna run. I just gotta get the car in the air and pull the shocks now. I'll be getting the shocks serviced in December and if all goes well I'll have everything back together by January 1.

The next AutoX I'm planning to go to is the Sac SCCA season opener. That will probably be March-ish. I'll be doing at least 1 HPDE between Jan and March.

 

Sorry, got confused
Yea I'm valving my own now it's definitely interesting and it doesn't always come out the way you thought it would
I think I've finally found a good base to work off of, traction, even in the cold last night seemed really good. Time will tell as well as the dyno definitely need to add some high speed rebound and low speed seems to be good so far but with only one short drive who knows

The process of valving a damper is super easy but trying to get what you want out of thin metal discs is a whole different thing. Now I see why they call it black magic, maybe a major in fluid dynamics might help understand the magic a bit more.
