As an owner of a stock (except for the REMUS exhaust) 2007 987.1 this information is extremely interesting. I honestly never even knew this technology (The Shaker) existed. I’m definitely going to be looking to change my suspension in the near future. Very, very cool seeing the comparison graphs. Thanks PCA and OHLINS for bringing us such quality content. It’s greatly appreciated.
Hey....that’s my 2007 Cayman and with the same color too!.....I got kind of lost on all the technicalities here but I can sure say one thing about this model: the Cayman is one fun, fun car to drive!....the steering and suspension are awesome......although the ride could be a little stiff and hard at times (so said my 6yr. old daughter at the time.....)....always great to see one’s car on a video......
Coil over suspension? A coil spring with a damper (shock absorber) going through the middle of it? The 987 comes with that configuration stock from the factory. I thoroughly enjoyed the video and hope PCA puts out more technical videos.
amazing video! this is what I suspected and it's great to see real science data to prove that putting lowering springs on stock dampers is about the worst thing you can do to a track car suspension wise. also I have the same car except an S model so it was enjoyable to watch.
What was the goal of the new suspension: Better than OEM Street, HPDE, Track Days, Race? Are the dampers custom valved or off the shelf? What spring rates? What shock settings did you settle on, F10 R7? How do you like the outcome?
The goal of the new suspension was primarily to make the the car better at autocross (aiming for STR class in SCCA for 2022), track days (HPDE), and driving on windy roads. The Öhlins R&T dampers are valved to work with the 400 lb front and 458 lb rear springs that come with the coilover package. In this sense, the dampers were custom tuned to these springs in this kit. Öhlins would recommend having the shocks revalved if softer or stiffer springs are used. The owner is still testing different shock settings, but he's liking 10 front 7 rear for autocross after starting around 10 f 10 r. He is also using the second softest setting on front antiroll bar (GT3 five-point adjustable) and stiffest of four settings in the rear (Tarett 19.1 mm bar). All things considered, the car rides no worse than stock; it definitely feels stiffer, but it handles bumps in a more fluid manner. Rides more like a GT2/3/4. At autocross, it's tough to nail down how much time has improved from event to event, but the owner figures he's about half a second to a second quicker than before. He'll be the first to admit that improving driver skill would have made a bigger difference than the new suspension, but he was aiming to refresh the suspension regardless and decided to upgrade. Driver mod still in progress. Overall he's very happy with the suspension.
Love how he mentions several times that a mismatched suspension modification will adversely effect the handling. With an Ohlin setup what besides the 63K old bushings might also need to be replaced?
The owner did not see any bushings that needed immediate replacement. The coilovers were fitted with Tarett front monoball camber plates and Öhlins rear monoball mounts, so the stock rubber shock mounts were replaced with spherical bushings with the coilovers. It should have been mentioned in the video that the front and rear antiroll bars are GT3 adjustable front and Tarett adjustable rear with new bushings, though those had been installed prior to the shake rig tests.
You'll need to ask Öhlins USA about potential group buys. The R&T coilovers for the 987.1 are just under $3,000. Tarett front monoball camber plates are $450. Öhlins rear monoball mounts are about $600. And the rear adjustable toe control arms from Tarett are $395. Call it roughly $4,500 for this Cayman's setup.
I just installed this Ohlins MR80 kit on my 987.2 Cayman S and I have a question - what will be the recommended height of the set? I am now on -30mm front and -40mm back and when I put the suspension to a soft setting (15clicks) it just because extremely jumpy.
Because ride-height adjustment and spring pre-load are adjusted separately on the R&T coilovers, lowering or raising the car will not shorten or lengthen shock travel or affect preload. This Cayman was set up for the test with Öhlins' recommended preload and ride-height settings, though we did not measure the car's ride height prior to or after the test. Overall the car is likely 20-30 mm lower than stock based on Öhlins' recommended settings. The owner of the car has since experimented with damping adjustments and has so far settled on 15 clicks front and rear for the street and 10 clicks front and 8 clicks rear for autocross with good results. He hasn't experienced any unpleasant jumpiness you describe. The car is definitely much stiffer than stock, though it handles sharp bumps better than before. We believe you can swap out the springs for a softer set, though you'd want to also talk to Öhlins about adjusting the internal damping shims to match softer springs.
You’re supposed to use preload to adjust ride height. The shock body length adjusted via the lower damper mount is used to configure where the tire is relative to the fender when the shock bottoms out. If too short, the tire will hit the fender before the shock bottoms. If too long, you will bottom the shock early and leave available tire travel on the table- effectively just running a higher center of gravity for no reason. A correctly set shock body length will bottom the shock just before the tire touches the fender. It’s adjustable so you can run shorter or taller tire diameters and still be able to compensate for that change. It’s also a cost-saving measure so multiple shock bodies can work with many cars. I suggest cross-checking this info with some of your contacts to reassure yourself and prevent the spread of misinformation going forward. Cheers!
How many miles and what kind of miles on the original 13 year old suspension? Seems the test would need to be done comparing new OEM to new Ohlins to be objective.
Car had about 63,000 miles on it. The owner felt it was time to replace it. We do note in the video that the original suspension was well used so viewers know that a new suspension may have performed differently.
Agree with you. I owned an 08 cayman S and a 2011 S. Both amazing cars. (Both black; manuals). I used mine for ‘spirited’ driving where I live in SD, CA. I trust Ze Germans know what they’re doing, however this video is really interesting. I believe a ‘refreshed’ stock setup would be great; especially in it make$ $en$e. Otherwise, these guys will set your car up properly and surpass the OEM abilities
I'm skeptical about suspension modifications. I don't want to sacrifice day to day ride comfort. Porsche spent a lot of time and money engineering a suspension that transitions between road and track. But "don't knock it until you try it" right? Maybe one day y'all will convince me
Educational and it would be nice to see a comparison of different aftermarket setups. I'm in for a group test organized by PCA for 987s!

Thanks for watching! Glad you learned something from the video, and hope the suspension upgrade goes well!
This channel is criminally under-subscribed. I unfortunately had to sell my 911 for economical reasons but love the content here!
Thanks for the subscribe call out! Glad you enjoy the content.
Why do people feel the need to divulge personal information?

Christer did an excellent job at explaining the process and findings. VERY interesting to me, a layman.
He did great!
1:44 - Oh those look like Bridgestone RE-71Rs, a beautiful match for a beautiful Cayman...
Great/Informative video! I had heard about shaker rigs but had no idea how they worked, and how useful they are. Thank you for a great video!
Thanks for watching!

Interesting info and nice looking garage.
Thanks! Öhlins was generous to allow us to use it to film this and a DIY coilover install. Hope you learned something new!
Wish I could give more than 1 thumbs up!
Glad you enjoyed it!

Great feature - very educative - many thanks for this !!!!!
the sine sweep for some reason seems like an automobile version of twerking. Im sure it's just me.
LOL
instead of a group getting together to test the shocks, can we get a discount for a group to buy the suspension? How much is that set up?
You'll need to ask Öhlins USA about potential group buys. The R&T coilovers for the 987.1 are just under $3,000. Tarett front monoball camber plates are $450.

How exactly does one get new OEM suspension on a 13 year old car? This is all about upgrading your stock Porsche suspension with OHLINS.
I'm skeptical about suspension modifications. I don't want to sacrifice day to day ride comfort. Porsche spent a lot of time and money engineering a suspension that transitions between road and track. But "don't knock it until you try it" right? Maybe one day y'all will convince me
If ride comfort is most importance, non sport factory suspension is the way to go.
