Just wanted to show a quick snapshot of the car with them on. Sonic Motorsport in Mountain View did a great job on these and I saw a TPC Cayman out front - great guys and highly recommended; they really know Caymans in and out from plenums to f/i.

Initial drop is 1" front 1.25" rear (update: have adjusted lower since). No real clanks or bothersome noises; then again, the roads around here are relatively clean. I'm currently running on 6 clicks soft for the winter (update: 4 front 6 rear) and while the car is noticeably stiffer, it is absolutely streetable on 19's and feels more planted on my drives up Woodside Road. Anyone care to join?

I have fitted them as well.

They are way better than the PSS( with PASM) that I was using. A little harder on the road, but brilliant handling.

Did you do any other suspension mods, toe links, camber plates etc. Thinking about making suspension mods, mostly track my 06 CS, but I am afraid once you start one mod leads to another. Thanks for your thoughts.

Yes I have installed everything Tarett produces as well as GT3 control arms and GT2 front wheel hubs.

But I already had all those with the Bilstein PSS9 and when I fitted JIC, I saw the car's tue potential.

It is true that when you start modifying it never ends, but that is up to you to control it! Shopping and driving therapy!

What settings are you currently using on your JICs? Shoot me a PM if you get the chance, thanks.

in the 15 scale, with 15th the hardest, I use 6 front and 8 rear. If you make it tougher it does not work well on the road.
I have not installed in the loowest setting about two fingers height front & rear.
If you are using stock rims it would be a good idea to go 1 scale, meaning 245 & 275 (I have fitted RE11 & they work brilliantly)

What you should fit is tarett antisway bars so you can adapt them as well, thios will completely alter you car.

The JICs come with the camber plates at the top, no? Did the shop doing your alignment use them to get the tire settings to spec? Curious whether lowering it slightly would require camber plates to get the optimal street setting. (And avoid premature tire wear.)

I set up my car without paying attention to tire wear, just performmance. The camber on ther rear is 2.7degrees and on the front 2.3degrees. I do not remember the caster settings, though I am way off the manufacturer's, I wil do an alignment to my car at the end of this week & I will upload my full settings. I ahave played a lot with the settings, both for road and track, and actually you must do 3-4 alignments until you adjust to your needs, even when you do not have the drop links antisway bars etc.

If you set them in the softest setting, do they become softer than stock non PASM ?
Thank you :)
That's the answer I want, too.

BTW, Scott, I was also looking at buying those and missed it to you by hours! (John was a straight-up and nice guy to talk to; bet the deal went quite smoothly!) Best of luck with them and I look forward to hearing how you like them and what settings (ride height and stiffness fore and aft) that you find best. I ended up buying a set of KW V3s which haven't arrived yet, so have many of the same questions and interest as you. Best to you and it was good talking with you in prior emails on different subject.

I do not know. Maybe one day when I'm working on the cars again I'll try it out temporarily, but I remember the nonPASM on 19's was plenty soft for me before. From bits and pieces of forum reading before my purchase, I'll guess full soft on JICs would be comparable to stock, if not a bit harder.

I was also considering the V3's from a local shop at the time, but the JICs were impossible to say no to - John was great. I hear great things about both setups. I most likely won't be able to experiment with the full range of settings for another few months, but keep me updated on how yours turn out.

I plan to lower both front and rear by a smidge, stiffen the rear, and go in for an alignment later this month.

Very nice... do you also have PASM in the car? How is the ride? How much do these coilovers go for? Link please?

Non-PASM. The ride is firm, but not overly. I had coilovers on my daily driver so I guess I'm used to it - when stock, the Cayman's suspension felt pretty soft to me.

Vivid sells them here but you can PM them for a slighly lower price.

I put the JIC's a couple of months ago and love them on the track, curious to what setting you guys are using in that environment?

Also my suspension is fairly noisy, but not sure if those are the JIC's or the H&R bars. Livable though.

Re: JIC Cross Coil-overs Installed

You can't have PASM with JIC; there's no provision for that.

I too have alot of noise, clank's when going over sharp drops like manhole covers. It's the JIC's as I have stock bars. I've had them for 2 years. I've always felt it was too bad the car hides the JIC's from view as they just totally beautiful.

I run mine adjusted to the middle setting both front and back. I started at full hard but found you couldn't run the car thru rough pavement autocross as it was too hard to control the car. Then I went full soft and the suspension wouldn't react fast enough to do autocrossing. That's when I when to the middle setting. It worked great for autocross and was street-able. On full soft they are not any where's need as comfortable as a PASM car on soft. More like sport with PASM.

Hi guys, Just had them installed on my car as well.

Yes WOW is cal I can say about the build, that something so nice can be built for about $500 each coilover. We had ours siting on our coffee table for about a week as an art piece :) ( I like to call it Car Porn )

We also installed the TPC racing Sways, Toes and Drop links as well.

So far we have been driving on the street with the settings on 2 all the way around. On this setting the dampening is much better then the PSS9's. The springs are about 100-150 lbs stiffer then the 9ss'9s as well. one thing I did learn about these if that if you have them set at one, it is essentially no dampening at all and you are riding 99% off of just the springs.

We set the camber at 3 in the front and 2.5 at the rear ( as recommended from TRG master alignment guy.... ) We also cut out the top part of the shock tower support so we can reach the adjustments on the camber plate so we can make easy changes as need be.

Yes we get the clanking noises as well, but do not know is it is the full race links or the JIC's

We will work out the kinks on the AX course to find out what sway bar and dampening settings work...
