Eibach R2's installed... Buttonwillow this weekend.

Eibach's philosophy has always been to improve performance while maintaining a streetable ride quality. I realize our rates are never going to be aggressive with our off-the-shelf kits. That's just how our engineers package the kits. Because of this I've set up pricing to sell the R2 shocks and springs separately so consumers can package their kits with what they want based on tires, brakes, aero, varying tracks, etc.

An actual shock/valving comparison would be ideal so the tester(s) can actually feel the difference in valving and adjustments. Since this is "where the magic lies" this is what I suggest. But that's just my two cents.

At the end of the day people are going to buy what they like. Some people may prefer green camber plates over red. And some people are going make anything they put on their car fast whether it's a one way or a triple way coilover.

What is the range of spring that the R2 can handle, and what is Eibach's recommendation for someone who is only concerned with cornering performance (as is likely the case for any R2 buyer)?

IMO, the best comparison is to mate each shock with the recommended spring, for an accurate comparison. Spring cost (afaik) doesn't change based on rate, so why is that even a variable? Isn't it logical to choose the spring that is best suited for a given damper?

Are Eibach's springs chosen based on the shock, or is the the shock designed around a spring?

I'll be at Buttonwillow this weekend, and be more than happy to provide feedback from the passenger seat.

We don't have enough seat time on this coilover to answer either of these questions 100% accurately. The valving can handle 650-700 (11.5k-12.5K) easy. We've tested a handful of rates but nothing higher than that.

You and I both know there's no magic spring rate that's going to work with everyone. For a novice on street tires I would recommend using the off-the-shelf rates as they will be very well balanced for street and track. From there they can package the kit with different rates as they get more seat time.

This sounds more like a Tein vs. Eibach shoot out. If the valving is where the magic lies, why don't we test just that magic? Anyone can switch springs out springs so why not test where the real money lies?

We plan to buy a BRZ sometime this year. As time goes on and we get more seat time with the car and suspension I'll be able to answer questions like these more accurately.

Our springs are chosen based on the vehicle's ride frequency and the valving is engineered loosely around that number. For some R2 kits like the S2000 we chose a low spring rate but valved them very high for consumers running 600lb+ rates. Every application is different.

@Jackson, i noticed that the R2 is sold outside the US. Is there a difference between the R2 valving outside the US compared to the US spec R2 (assuming for the same car)? How does Eibach of Japan differ than Eibach of US? Is R&D completey separate?

When can I buy some of these?

FWIW I agree. These dampers should be setup within each dampers design parameters.

The test conditions (i.e. car setup, track, temps) should be the same.

omg i want some TRD branded Eibach coilovers!!!

can somebody confirm?

Pretty!

Pics from the Pro-Am FRS testing at SoWS? :p

I understand why everybody wants to know why one system might appear to be faster than another, but at the end of the day, whats faster for one driver, may not be faster for another driver, right? Its all personal preference. I don't think any of these systems are bad systems.

The Multi Pro coilover line is only made here at Eibach North America. What they sell, we make.

I just ordered the Eibach R2 with off the shelf springs. I'd like to do a comparison vs the SRC for the sake of this forum but not really sure how to do so. If it was between your car and mine, they have similar parts but the two biggest things would be the alignment and my stock tires.

Then again i'm planning on getting an alignment at Westend but not sure if you want to share your specs and i'm not sure if I want such an aggressive alignment.

I have a set of the R2's installed with their off the shelf spring rates. But then everything else is stock besides tires. I'll be at Chuckwalla this weekend. I'd be glad to contribute to the comparison if anyone has a near stock 86 with SRC.

Their videos states -3.4 camber front and -2.4 rear

I'm not sure if I want that much camber. I'm guessing the rest of there settings is setup aggressively. Maybe I should since I need to wear these stock tires out faster. I've had the car since June and the tires still look brand new
