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.

Simply put, you are basically stuck with that particular spring rate since the valving is tailored specifically to that spring rate.

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).

On top of that, most people are not able to tune 2-ways properly. To give you an idea, many clients come to us asking us to help them out with their suspension setups, more particularly KW V3 or Club Sport owners. They end up realizing their rebound and compression settings are way off.

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...

Ohlins has a proven background, but do not always look at the name for quality. There is a reason behind the price difference. The TEIN SRCs are a completely different class from the rest of the TEIN lineup just like Ohlins TTX is completely different from their DFV stuff.
|
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 are adjustments on the R&T with camber plates. So I'm not sure what adjustability you're looking for?
|
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!

True story. I'm glad you pointed that out. As a fellow veteran S2k owner, your opinion is much appreciated in this forum. :thumbsup:

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!

The benefit of a 2-way is much more effective in the hands of the proper user/tuner. While Ohlins R&T is extremely high end compared to their competitors (unless you're pointing out the ASM Sachs stuff...:wub:), it also utilizes proper engineering to provide significant differences per click. This is one of the best 1-way available on the market and it's proven to be rightfully so. :thumbsup:

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 :)
