Is that how much he charges to do a revalve!?! That is insane. You could likely have PSI (http://performanceshock.com) revalve the DFVs to whatever setup you want for not much more over the cost of the DFVs. Or even have them do valving for you on your Bilsteins.

When I go to a square setup I plan to move to 12 or 13kg springs all around and I will most definitely be having PSI do the rebuild and revalve. One because they are an hour away from me, and even better, they have real works level motorsport experience.

My ride height is 330mm from wheel center to fender. On my next alignment I will have this reset and remeasured now that they are broken in.

Spoon Pressure Plate, new wheel hubs and bearings:



Picked up a few maintenance items and a Spoon pressure plate as I am planning to replace the clutch soon as I am getting close to 100k miles. Starting to get some ticking and rough sounds from my front bearings so going to replace those as well. I plan on using the Spoon pressure plate with an OEM disk and an AP1 flywheel. I was considering something like an Exedy Hyper Single VF or O.S. Giken setup, but first I wanted to try out a stronger than OEM pressure plate like what the Spoon one offers to keep it nice and streetable. Maybe I will go for something more aggressive in the future but I think I will be served well by this setup.

You're going to love the change to an AP1 flywheel. It really wakes the car up.

Its not just a revalve, the entire shock is re done, machining of the perches, new springs, custom top hats, spring retainers,new springs, valves etc. But yes, it is approximately that price for the whole shebang. Im sure PSI does a great job, but after doing extensive research and riding in A.R.E. prepped s2000's its absolutely unbelievable how composed the car is in all situations both on track and autox. The ap1 flywheel prepped with the a stronger pressure plate with the oem disk should be a great combo, youll be able to retain the stock street driving characteristics with much more clamping force to prevent that slip that the ap2s have which is in part due to the heavier ap2 flywheel/weak oem PP and not so much the cdv.

Ah that makes sense.

Yeah that was my thought process as well with the CDV. More a problem with the heavier flywheel and not necessarily the CDV.

I'm currently in the process of having some Bilsteins revalved by Guy. I'd be wary of sending Bilsteins to PSI for revalving - I'm sure they know their stuff when it comes to other shocks, but they don't know how to do Bilsteins. I bought a set of Bilsteins that had been revalved numerous times by PSI by two different users. At the end of the day, neither user was happy with the valving/handling of the car.

I sent Bilsteins that had been previously revalved by PSI to Guy at A.R.E. This is what he found after dynoing the shocks.

so here’s what I found-Front shocks way too harsh and not enough compression. Valving is dbl digressive. I can make them better, but I believe they have changed the pistons. Wouldn’t know if I can get to where I want to go until I try. Figure costs $200 each. The rears are really bad. One shock appears to have leaked oil-short shaft one. I filled with nitrogen-it was low WHY? Leaked? If it leaked it will be very hard to get parts for. Or ????? The second shock was dynoed—Whoever rebuilt the shocks had at least that piston in upside down. Compression numbers well over 500 lb/in-horrible. I have no idea what they did internally. I don’t believe either would work on a street or race car.

I essentially paid a little bit extra for a shock that I thought was "reworked" with trick parts and would have made the revalving/tuning process easier and cheaper. Exact opposite... I would have been better off buying a brand new set of Bilsteins or a used set that had never been touched (difficult to find used set at all - i'd been searching for about 2 months or so). If you want to use PSI, take one of their higher end shocks like 8300s or TTX - since i'm sure they're more knowledgeable about those shocks. With the Bilsteins, I think they were just taking stabs in the dark - not that they don't know their stuff, but Bilsteins are not their shock of expertise. The same goes for Guy - he's specifically a Penske 8300 or Bilstein specialist. Another user asked him to work on AST4150s, and he said he wouldn't touch them. I asked about Koni's, and no go as well.

Here's another user's experience with Guy at A.R.E. using Evasive spec SRCs. He had to work with both Guy for the dyno knowledge/tuning, and Tein for the actual physical revalving to requested specs.
https://www.s2ki.com/s2000/topic/108...srcs-compared/

People have won National Championships with Guy's revalved 8300s, and will vouch for the quality and handling of his Bilsteins. I'm going on faith here, for what i'm about to pay for the shock and services, I could easily have a number of quality OTS shocks (including DFVs).

At the end of the day, most "higher end" OTS shocks will be an improvement over stock. However; if you really want to get the most out of a shock - find what your local tuner specializes in and go with that recommended shock.

Sorry Andrew, [/thread jack]

sillyboybmxer

I'm that user that wanted the AST's done buy Guy.^
They are essentially for sale only because I want his 8300s I am curious as to how he works though as in, are all the 8300s the same? or does he base it off what you want to do with the car? I want some of the Jonathan Lugod special sauce shock magic but dont want to suffer on the track/street.

I am interested in this clutch job. Im at 102k on my car all original, I have noticed increased of what I assume is flywheel/clutch noise. Is that a sign its wearing ?? I have no signs of slipping even in all the autox I do

I saw the SRC thread and if my friend Edwin drove the car and said it was undriveable I believe him. He is one on a small list of drivers who's opinion I take very seriously. That said he has also driven an S2000 with a different set of EVS SRCs (the set I own) and said it was beautifully composed and better than his own standard SRCs. And there are numerous other examples of people who are incredibly fast on all flavors of SRC. I am of the opinion that the problem he was having wasn't really verified, as his experience doesn't at all match the majority of users. Seems like something else was going on there.

It's funny now how concerned I was switching from OEM ride height and suspension that I might not be able to handle some of the rougher roads I like to drive, due to ride height and spring rate, and with my current setup the car is almost comically improved over stock on these roads.

I keep returning to this thread. It is one of the sole reasons I am saving for a facelift AP1 (we don't get AP2 here as you probably already know). Can't wait to see what happens next! Especially your experience of a square setup

I have a feeling that you're looking to get a square setup soon...
