Like ZDan said, 1-way is supposed to adjust rebound and compression simultaneously in proportion to each other, but in reality, 1-way adjustable setups affect rebound more than the compression.

In my limited experience with them, and lacking any shock dyno data, I'll just say that it seems to me that the adjustment on the Ohlins DFV affects low-speed compression damping commensurately with rebound damping.

Should be noted that a 10% change in spring rate only requires a 5% change in damping to give the same percentage of critical damping. The Ohlins give a quite perceptible change in both rebound and compression damping per click in the 1 to ~8 clicks out range on my FD RX-7 (beyond that they seem a bit underdamped with less noticeable change between clicks). I'm thinking about increasing front spring rate from 11 to 13 kg/mm, and I think the damping adjustment range will accommodate this (will check w/ Ohlins first), possibly at the cost of resolution (i.e., probably a bigger jump between clicks in the trackable range, which is ~4-6 clicks with 11kg springs, probably 2-4 clicks with 13).

Yup, safe to say that most of us mortals don't get *nearly* enough dedicated track time for tuning to REALLY optimize multiple settings. If it's possible to get a set of dampers that have already been developed for a specific application, less likely to get lost in the wilderness...


I don't know if the two are analogous. Having just come from a set of single-adjustable Tein SuperStreets that were utter CRAP, i can say that the single-adjustable Ohlins are in a TOTALLY different ballpark! You can't just throw the Ohlins DFVs in with the majority of Tein's single-adjustable range of coilovers. Tein sells stuff that is pretty much garbage. Ohlins does not.

There was a spurious comment on the thread that seemed to indicate that the Ohlins DFV didn't have camber adjustability, I fell for it too. Good to know that they do allow front camber adjustability!

Weirdly enough, since the S2k has always been my DD/backup track car I've never messed with its suspension at all! Great stock suspension. A bit undersprung and underdamped, but the low/high-speed damping is very digressive and has not deteriorated over 160k miles of street and track usage!

Totally agree. For *most* users, I think they're going to be the best bet. To me the rebound/compression damping is right where it needs to be for the range I'm using (I'm 6 clicks out on the street, 4F/5R clicks out at the track on the RX-7). I.e., I don't find myself wishing I could separate rebound and compression damping adjustment. But I'm not a dedicated die-hard track junkie, either. I go to the track and work out a usable setup and drive :)

If you are interested in having your multi-way coilovers dialed by CSG, let us know. :thumbsup:

AST 4150 singles would be basically an Ohlins R&T direct competitor. You just can't compare a 1-way adjustable setup to 2-way, unless you are capable of developing your own valving with the proper internals...which can get pretty pricey. You can even build a non-adjustable shock and make it look stock with the proper valving. It's just extremely time consuming and expensive. :)

While we haven't tested AST 4250 extensively, I'd venture to say it's basically JRZ and TEIN SRC territory. Meaning, it's good and considering AST builds excellent stuff, I would be optimistic for these. If you can afford this, I'm sure you can afford the revalving. Most base valving setups are usually pretty generic. Some work extremely well and some are so-so. We found that the JRZ soaked up road imperfections barely better than the TEIN SRCs, but the CSG Spec valved TEIN SRCs are better than the JRZs. How do we know? We have a car with JRZs and a car with the TEIN SRC CSG Spec valving that we drive back to back all the time.

JRZ is proven and we have had extensive experience with these units on the BRZ/FRS. Let us know if you're interested. :)

Reason why I mentioned the AST was because I was rather impressed with the features they offer at the price point on their 4150/4250 line. Particularly the double digressive valving and the ability to upgrade to 2 way. So with this set up you can run the single, test it, and upon time for rebuild and/or revalve one can upgrade to a double adjustable if one chooses. Only other manufacture to offer similar features at the price point is Fortune Auto with their top of the line offering. Although, the dyno of their version of the double digressive valving looks rather strange...

I'm not in the market at this moment but I definitely will be. I plan to add some coilovers sometime next year. Will definitely hit you guys up when that time comes. :thanks: The SRC's you guys developed is high on my list of considerations.

You are in California, just hit us up if you're interested in a ride just to find out how the SRCs feel. We have been working with Imperious Rex's BRZ for awhile and his JRZ are pretty sweet too. :thumbsup:

That's been my experience with the DFVs on my street/track RX-7. For dedicated well-developed pure track cars, you may need separately adjustable rebound and compression (and for both high- and low-speed) to get an ideal setup at different tracks. IMO, for more "streetish" cars, *if* the ratio of rebound to compression damping is appropriate throughout the adjustment range, I don't see any real drawback, particularly for a street/track application.

I'd definitely rather have 1-way adjustables with good digressive curves with the knee in the right place and with the adjustability primarily being to the low-speed damping, than a 2-way that was too harsh at high speeds and/or too soft in low-speed damping for a given setting.

Come to think of it, I'd rather have separately adjustable high- and low-speed damping than separately adjustable rebound and compression with no hi/lo adjustability. Don't think anybody makes them like that, though...

has much changed in this area? I am getting into a similar boat. I think I might end up with ohlins because I don't think i will know enough to properly set up the 2 ways. and I am more on the 80% street and 20% track side of things

The high and low speed sections are starting to hurt us, as high speed corners we can't attack the curbing because we have no high speed damping ability. The car literally jumps to the other side of the track.



We've heard great things about SRC

We've heard good things about RCE.

We've heard good things about Moton.

We've heard good things about JRZ.



Does anyone feel like pitching a product?



Price wise, why go 3 way when 4 way is also pricey? Is high speed rebound not so much of a concern?



I apologize in advance. I know NOTHING about suspension, I just turn clicks on the ohlins to make them softer or harder.

From what I've seen the Ohlins has a very nice blow off on the compression damping at shaft speed over 2" per second. Hard to believe that they'd make the car shoot off curbing. Maybe you should share your settings and compare with what other guys are running before you chuck them altogether.

OTOH if you are determined to replace and sell the Ohlins... shoot me a PM maybe I'll pick them up from you if the price is right. :D
