Replacement Springs for Ground Controls...

What spring rate are you looking for? I think I have a set of new Eibach 500's and a set of 550's collecting dust in my garage.

that's what I've got. I'm going to go with either 650/700 or 700/750. The guy I bought my QA1s from was running much higher than that but he raced his V. But he also recommended Hyperco springs for being more consistent and generally better made...

same price it seems, unless someone can find cheaper...

Also, could someone who has a pic of their own QA1s poast them?

Hyperco? I am no expert but Eibach is more renowned in my experience. Check with some more people who know better than I before you make your spring choice Jimbo. Did the guy that raced his V have brake ducting on his car?

I believe he did. He said most of the guys on the circuit were running Hyperco.

no other thoughts?

Hyperco is what Maximum Motorsports sell and run on there AI car.

Jim, when you they're "more consistent," are you referring to the spring rate from spring to spring? Or do you mean from compression stroke to compression stroke? I can understand the former; the latter, I guess, doesn't make sense.

Not many hits on this thread, so it must be that not many have done this. (Note my firm grip of the obvious.)

More consistent spring to spring. I'm thinking I'll stick with Eibach just so I can mix and match and sell to someone else if I decide to go another route...

You could get a pair of each spring rate and experiment with different rates, instead of staying 50 apart front to rear maybe try 100 and see how that feels, that should help free the rear of the car up some also, loose is fast.
