i would recommend camber plates in front for two reasons-
they will give you more front neg camber-very good!!
and they take out rubber mounts which helps the suspension work
better and tune easier!!!! rear helps -but makes alot of noise on street
so i wouldnt ad if noise echo thru suspension is a problem for you...ray

 

I think for daily driving on the street the PSS9/10 option is fine...but for track work or for the person that is into control/set-up....the JIC may be better. That is why I went JIC..it seemed like an affordable version of Motons at the time..... I like the ***** on the PSS10 a lot.

For me, it is more than what I need.

KWv3's seemed pretty great too at the time....I just wanted the adjustability out of the box....in my budget. IF I run into support issues, I'll likely go to KWv3's or JRZ's or Motons if I am still on track. If not, PSS10's.

I'd like to hear from someone who has tried both, if there is a difference between JICs and PSS9/10s, other than spring rates and camber plates... or if that's the main thing? When PSS9s were around 2000 a set, it seems that for about $3300 total, one could have camber plated, custom valved, custom sprung, reliable, single-adjustable coilovers, which is not a bad value. That's 10% more than a set of JIC Cross, which seems worth while for extra reliability, and total customization. So, I'm still curious as to what other adjustments the JIC have that makes them so often recommended. (Note, not even Moton/JRZ/Bilstein/ race parts have adjustable damper body lengths, so I don't know that this is a real feature...)

Of course, this is just a hair under the price of JRZ RS coilovers, with camber plates... so, where does it end... =)

 

Jeff, Trust me, there's a lot more that encompases proper suspension geometery than you might imagine. My suspension education goes back a number of years and I've got some specialized training thru manufacturers like MOOG, KONI and others. I'm sure that JICs are fine for most folks. Reality is that they are an expense, and have a history I don't need. The long list of problems associated with their QC are well documented. Kudos to Dan and Vivid for doing everything a vendor can do to work with customers in making up for the shortcomings of the manufacturer... Me personally, I'd be on a plane and having serious discussions with the individual who makes them if I were to deal with the problems some have outlines here. F-THAT.

Bottom line is that PSS9s for me are "free", since they came on the car. I'll replace them ONLY with something that is truly a pro grade upgrade. Jics are a minimal upgrade, due to the pillow ***** and camber plates. No thanks.

To all. Mike knows a LOT more than I do....go with him on things as he used to sell/do suspension.

That being said, I agree...if Dan was not the "man" for support...I'd be less comfortable.

Just get the Motons! You are good enough to actually "need" them. I am not.

 

Jeff, I don't know a "lot" more than you. I know a lot about suspensions, suspension designed, suspension component function, and suspension geometry. Beyond that, I'm an idiot...

I'm not sure we have anyone on this board that isn't a vendor who has tried both. Here's the thing... A number of FAST track guys here have gone the JIC route and been very happy. If I were shopping for a set of "first" coil overs, and didn't know about the customer service/QC problems "some" have experienced (Dez and Tom Kerr both driver harder than I do and they haven't reported issues with JICs.) I'd probably be inclined to go for a VIVID racing Special on their suspension, just as Jeff did. I'd probably be just as happy or happier with them than I am with my PSS9s. They're probably just fine for a single adjustable shock with camber plates/pillow ***** and your choice of spring rates.

But that's not "my" situation. I'd want to see a shock dyno and some of the types of data you posted in the other thread about the valving and performance values of the shock. I'd also want to know where the parts sources for a rebuild would come from.

I'm sure they're a "fine" shock. I already have a "fine" shock. A pair of camber plates for the front and upper control arms for the rear should get me all the camber I need for the compromise Im' looking for with the PSS9s.

Mike - still in the office. let me know when you are ready to order.

 

Hey Dan. Is there any chance that you've Dyno'd front/rear JIC Cross dampers and have any data on the damping? It would be really great if you could provide us with some more info on the valving! Thanks.

 

If I put a JIC shock on my Mustang Dyno, it might break something!!! Unfortunately I dont have a shock dyno. We dont need one as we dont make shocks I will see if JIC has some of this data. But in the end, they are proven in their competition results, performance on the track, and numerous customers with positive feedback.

 

Heh... It would be interesting to see how well the JIC turns the Mustang Dyno. =) Thanks for asking JIC for valving data, on our behalf... it's not really about proving anything. Just useful info to help the data heads amongst us bench tune. =) For what it's worth, I'm seeking out this information for all the suspensions that go on our cars. Thanks!
