Cayman Suspensiom Thread

[stealthn]

I've got a Cayman S with PASM and Sport Chrono and I've been reading through the suspension articles, but wanted to get input on the Cayman suspension. I am looking at mainly street but also autoX and tracking. If find the PASM still a little mellow compared to my setup SC, and I know a TBD is going to be required. Looked at the PSS' but man they are expensive. Got Wayne's Boxster book and the Tarrent and PSS set is very nice.

I am looking at a phased bang for buck kind of approach, larger sways first because...... As and example.

What say ye?

I am definitely interested in this thread. My Boxster has the US M030, and I too would ike to improve but in a phased approach.

Basically a bump here!

Found another thread that covers a lot of this stuff..

Front Sway Bar? - 986 Forum - for Porsche Boxster Owners and Others

Yes but I was hoping we could keep the wisdom on Pelican.


Any pelicans done incremental updates and noted the differences

[arethusa71]

Funny- You know, i pulled that link from another pelican thread, and i didnt even notice it was external. Got ya.

Update, after driving a lot more it is apparent the one thing this Cayman needs is a torque biasing differential, or limited slip. Going around 90 turn or around a round a bout the inside wheel chirps and bucks.

Anyone here do the TBD themselves, how tough is it?

Cheers,

I'm thinking of the Tarrett drop links and sways as a start, do some people just do the front sways?

What difference if any is there just doing the sways? I knw on the 911 I did the shocks first and the car was a lot more bouncy until I did larger torsions.

Thanks

New Year bump,

Sadly car sits waiting for winter to end but getting the planning done now.

I figured the TBD was a little over my head so I would have my mechanic do it. I'll go with the Quaife TBD.
Next will be sways, I've decided on RSS adjustables with Anze adjustable drop links. I'll stick with this config for the year to see how it works for me.

After that probably the Bilstein Damptronics

Will post as I go through these mods.

Old thread revived.
My car went through a multi-year transformation and most experienced drivers that have driven it like the setup as a good compromise between on-track precision and street drivable comfort.

A few questions for a clear picture first:

1. What do you want the car to do that it is not doing now? If it ain't broke, don't fix it.

2. What tires do you plan to run? Suspension is after all, just managing our contact patch so tire choices will steer suspension needs.

3. How much performance driving experience do you have. A first year DE driver will have very different needs than a Grand-Am pro driver setting up a joyride.

4. How many miles on your current suspension now? A car with 20k miles has a lot left in the current struts. A car with 85k needs to start shopping soon.

Good questions,

Mainly street with some DE's and autoX's - 75-25

My 911 is like a go cart and I like the plant and precision, this is what I want for the cayman. Currently it's got too much push and body roll for me, and the lack of LSD/TBD can really be felt.
Tires will be street, I think it's got Pilots now
The car has 47k miles on it now.
My driving I would say is a little better than a newbie and I'm always learning, I've pushed my 911 to the limits and realized I was the limiting factor

That's about it...

Good info. I have really been pretty impressed with well set up PASM cars that were dual-purpose. If it were mine, a set of adjustable sways to control car balance and front GT3 adjustable A-arms to get more negative camber and make the most of your front contact patch would be the first step. The struts are probably still in good shape and work well once you get full use of your front tire. A 245/275 stagger is also a preferred tire setup for a Cay S. I think a LSD is ideal for trailered race cars on full track suspension and comp tires but might be overkill for a street/DE car. There are other ways to control wheel spin.

My 2c

^I think that makes a lot of sense, particularly getting more neg camber in front to get that end of the car working better in roll. You can use the adjustable bars to increase the front roll couple, which will help with inside rear wheelspin, but that has to be balanced with other aspects of the set up to avoid understeer (all other things equal).

Ok while dropping the exhaust I see a rear PASM shock leaking. Not the question, go with PASM (factory) again for the rears, look at a full Damptronic or other suspension ( I don't need that much adjustment), or go factory rears and play with adjustable sways. I already have front camber set ( don't remember the settings).

What say ye?

What are other PASM replacement options?
