finally adjustable Bilsteins

Adjustable Bilsteins for pre '90 911s

[Duc Hunter]

Wow…..$$$$….even compare to my Ohlins Road/Track my 996TT.

Nice edition to the aircoled market though.

Not vastly different in price vs the K3 V3’s w/ raised spindles. Easy $5.5k for the set too.

At a glance it looks like the Bils might be raised spindle (maybe 15mm?) but only single adjustable. Nice to have them as an option, very OE+ if that's your thing.

Whatever flavor you favor, add +25% for tariffs...

[nickelplated5s]

There's always coil overs and a GT3 front if you want to go that route.

[famoroso]

I'll leave these here. Allegedly, Nitron's offering is "coming soon," replete with single or double adjustability and different height, swappable, steering arms depending on which spindle height you choose...








Also, rumor has it that Eisenlohr Racing Products is in R&D for a G Body offering.

God bless America, it's an embarrassment of riches.

nice!!

I'm looking for an inverted monotube gas shock
at least 30mm raised spindles and or shorter body
adjustable height steering knuckle
digressive valve stack, high pressure blow off is a plus
adjustable valving is a plus

all the available shocks I have seen offer some of these features, none offers all of them, it's seems odd to me that for far more plebian cars these features are all available

the Bilstein b16 g series shocks seem to be right there except for spindle height and steering knuckle height which can be fixed

got links for the Nitro and Eisenlohr products?

Cary & co. seem to be working on double arm 964/993/996/997 front ends these days


They also did a double arm for G series 91 but I have no info on it

[Jeff Alton]

If we are in that price range, we use MCS www.motioncontrolsuspension.com We talk with their team about car weight (corner weight) spring rate, desired use of car etc... and get a custom set of dampners...

We have done a couple G-body cars and countless later watercooled platforms and the products are fantastic.

Cheers

I am not familiar with Nitron. Though I see they have a wide selection of offerings acrsoss cars and motorcycles.

The machining could use some finer finish passes but that is clearly a far from finished part. Not sure how I feel about the bolt on nature of the spindle and toe link arm.....

cheers

Looks like a 3d printed sample - can't wait to see that finished product!

I acquired my first set of V3s (plated versions) for ~$3k in 2020. I acquired my second set (also plated) in 2021 for ~$3,300. As much as I like them, especially for road tour / rally use, I cringe at the current $4k+ price tag (for the now painted versions). Ugh.

Nitron estimated price is ~$6,500.

Alas, no links, but I'll inquire.

As seen at ERP's Air|Water 2025 booth...



...The upper A-arm mount is pretty slick, but I can't imagine many 993 owners will be cutting up their chassis for it. OTOH, I've driven a 993 with, among other things, ERP's RS uprights, on the road and at the track, and I'd be DELIGHTED to have that setup on a 993, if I can ever afford one. ;-)

Yes, relatively unknown in the Porsche world, especially the air cooled hemisphere. They have had Lotus offerings for a long time, single, double, triple adjustables, etc. I had double adjustable, remote reservoir versions on my Elise track car for 14k miles and 100+ track days. They were excellent, both more comfortable (even with considerably higher rate springs) and provided more body control than the Lotus factory Bilstein Sport package suspension. I did have them rebuilt at that point, but I am totally happy with their performance / longevity, given the severity of my use case.

Yessir. That's a 3D printed item.

Note the silver fitting near the bottom of the body. That's for the double adjustable version's external canister. The single adjustable version will not require a remote reservoir.

yeah, my 993 has the RS/Cup/RSR uprights, Cary's raise the spindle another ~10mm
They had a teething problem w/ the early bearing retainer plate bolts, looks like that has been rectified


right now the MCS look like the best option for a G series 911(even though mine is really an I series), I was just shocked when I ran across the PS10 Bilsteins for G series, in the 964 up world they are a very nice street option, a couple of steps down from MCS

[Jjm4life]

Had Nitrons on my exige years ago. Great quality wouldn’t hesitate to try out their Porsche stuff

[JackkTheMackk]

Have you guys seen what NTP in Europe sells?

https://www.ntp.it/english/motorsport/marken/porsche.html

3-way adjustable Bilstein dampers in rebound and bump (low- and high-speed)

Bilstein PSS10 front shock absorbers for the Porsche 911 adjustable in rebound and bump with 10 clicks. Complete new front strut from Porsche Original. With 40mm cartridge and Bilstein PSS10 regulation incl. coil over system and specific setting on-demand and also travel for the use what the customer needs (street-use, race, rally etc.)
Bilstein MDS shock absorbers rear – with 2-way adjustable in rebound and compression or also with the Bilstein PSS10 System.

[Jeff Alton]

For the G-Body cars, those PSS10 would be like all other PSS10, a crude 2 way, in that they adjust compression and rebound together, but not independently. Fine for street use. But be prepared for a failure, and then a lack of support while your car is down...

Cheers

[ian c2]

A little bit rough as well …..

So on the MCS 2WR for classic 911
for a car that's 60+mm lower than stock
how long a shock body do you recommend?

how does MCS handle steering knuckle height adjustment, single sheer, double?

I see that they have 2 options
cartridge that uses donor spindle 2way
new spindle 2wnr

What advantage does the new version offer?


i

[Jeff Alton]

Apples to Apples....

2WR are remote canister. Also available is a 2WNR, no remote canister. You can talk to an engineer about your car's weight and spring rate and the way you want to drive it (track, performance street, or a mixture of both, even talk tire compounds). Then get a custom valved set up vs an off the shelf product. Kinda like when Jack French was still alive and working at Bilstien NA and you could get custom help....

For your 60mm specific requirement, talk to them. Or have a dealer talk to them on your behalf.

Cheers
