Default OEM suspension vs revalved suspension with 600/800 spring rates ride quality

Hi All,

I am thinking of having my shocks revalved to OEM specs given that I am likely to be doing more driving on the street/canyons as opposed to track in the immediate future. The thing is when I bought the car it already had the suspension revalved to match H&R springs F=629lbs R=800lbs so I have no idea what "stock" feels like.

For you guys out there with similar specs, was the ride quality noticeably softer with the OEM setup before switching over? The reason I ask is that I read a few posts saying that the stock spring rates and dampers were not well matched so ride quality actually improved with the stiffer spring rates and revalve. If that's the case, then I will probably just stick with what I have now. Thanks a lot.

Stick with what you've got. The OEM dampers were a little too harsh from a valving perspective for the soft OEM springs however if you swing that the other direction and have too much spring for soft valving then you're going to wind up in a situation where the damper cannot control the spring and the car will pogo all over the place and not handle well at all.

I think Bilstein stopped revalving OEM stuff (at least for our cars), so you may be stuck unless you have an aftermarket source for OEM work. Personally, I didn't like stock and "upgraded" to 600/800 long ago. As Andy said, stick with it - you won't enjoy going back to floaty coach.

Thanks for the input guys. I actually just contacted Bilstein and they said the same thing about not doing revalving anymore, however it looks like there are a few independent shops (Dan Jacobs, Elephant Racing, Rennsport systems) that still do it.

@himself was the ride noticeably softer stock on the street? The wife currently refuses to ride in my car and I wonder if it would help. That said, I'm leaning towards just keeping it as is.

Didn't do much street driving, and, honestly, it was so long ago, I don't even remember if it was softer. My wife won't ride in mine either between the seats/harshness/loudness. Oh well, she was just messing up the corner balance anyway.

Driven my wife for just 3 blocks. She said let me off : (. It'll probably be the same with stock revalve. I think the only way is going 2 way moton or similar with remote reservoir to adjust for comfort. Mike

I am interested in the Ohlin R&T - wondering how they ride on street (and perform on track) vs. OE.

If I understand correctly they are 400/800lbs.

Just throwing that out there as a possible package solution.

Cheers

Matt

A track buddy of mine had 2 way motons and one session he forgot to adjust for track and left it at comfort and it was softly sprung. Probably best option- best of both worlds ie comfort for the street and knife precision on the track. If you go that route do not sell your stock oem suspension. If you plan to sell car some people like purely stock cars. Better resale value if all stock. Mike

Thanks for the input everyone. It looks like the popular consensus is that it's not worth it to do a revalve to stock specs. Either I should get an adjustable set up or just pick up a used 996 GT3 suspension. I will look into the adjustable set up but in the meantime if anyone has a used OEM 996 GT3 suspension sitting around that they can sell me, please let me know.

Thanks,
Andrew

I got Ohlins R&T with 600/800 springs. Ordered them from PSI and they revalve the fronts to suit the 600 springs. Total cost is about $1000 more than if I revalve the stock dampers with new springs.

I went this route so I still have the stock suspension and can sell the ohlins when I am done.

The R&T are great the small road imperfections get soaked up beautifully at speed...ie great compliance.
Almost 30k on mine street and track. Makes the car

I have about 16k on mine and love them. They mitigate the seesaw effect of the stock coil-overs.
