just some thoughts, after talking with the local js dealer (good friend of mine), I think the mistake was made by me through my order. Monday when I will remove the js rca from the car will verify my memory that my rca is summetrical with NO offset ball joint.

Unfortunally my car is at a friend's house and I will have it tonight, that's why I cannot take new photos. But even if I had the car, I wouldn't bother to check the rca. I want to take it out and check to be 100% sure and also to take some photos for you guys as reward for bothering your minds those 2 days. Thanx guys

Now this is the rca I ordered - CAJ-S1-S1



Now forget the blue and red, the red ones are the new ones. According to js S1 can MAX to -2 or -3 degree, depending on the ride height. So there is nothing wrong with my installation or the product, everything works perfect. (max camber -2,6 my car sits on descend drop, with 1cm more drop I am sure rca will give me -3 degree camber). That's why I believe and I remember that the s1 is symmetrical with out offset balljoint.

Now js rca S2 product has an offset balljoint and can max to -3 to -5 degree again depending on the ride height.

Below you can see some photos of the MY08 OEM part. Even some guys don't believed,but I am pretty sure I could get easily on OEM MY08 suspension and OEM ride height camber at -2,5 degrees.









OEM suspension, OEM ride height, -2,5 degree camber



Now all of the above is just some thoughts Monday or Tuesday I will know the truth.

Thank you ALL OF YOU GUYS for your patient and your informations

 

Definitely there is no way to achieve -2.5 degrees of camber with OEM suspension components (OEM coilovers, oem balljoints) something's broken if that can happen.

Also the js s1 is definitely offset. Look at the center line for the balljoint pin in relation to the 2 mount bolt positions to the knuckle. On the OEM camber joint they are all inline, on the js there is a bias between the 3 points.

Im pretty scared to even install my s1 now. I want to be about an inch lower than stock. No more. And want to achieve -3.5 to clear my tires.
I tried to order the s2 but was talked out of it by gotuning. Was told an additional 2-3 degrees can be gained with s1. I was at -2.7,granted I was lower but assuming raised up a tad wouldn't limit me THAT much.

 

and I can assure you that nothing is broken!!!! Everything working perfect on straight line, on high speed curves etc... Even the tyres wear - left, right- is exactly the same. As I said I am the original owner of the car, I bought brand new.


As I told before, on Monday or Tuesday I will take a photo of the s1. You can wait and see!! That's the reason I ordered s1 on the first place.For the ''additional'' degrees.

I wont argue about my max camber (-2,5) on my OEM suspension but lets say you can obtain -2camber on oem suspension and oem ride height. If you go lower with coilovers, that means you can have max camber -2,5 approximately (I am just throwing a reasonable camber).?? If you use the s1 you can have an additional 2-3 degrees it means you go to 5,5degrees. If someone uses the s2 that means you can obtain 7,5degrees max camber.

Come on guys do you know how much cm pin movement you must have to obtain that kind of angle??? Aproximately 1,5-2cm movement!!!!! Does someone of you believe that this thing, even the s2 can move so much??? I believe we misunderstand the js statement. I mean with s1 you don't get additional 2-3degree camber, I believe they mean you can obtain max -3degree camber, DEPENDING on the drop. The same with S2, you can OBTAIN -5degree, again depending on the drop.

I don't think js will sell a product that give you 7degree camber, I mean who uses 7 degree camber. Semislick tyres work perfect on 3-3,5degree range and slicks on 3,5-4 degree. Now 5+ degree...... good luck

 

Return it and get the s2. If everyone listened to go tuning we'd all be running around with messed up fenders, a $2k exhaust that rattles, race suspension that won't last a season and wouldn't be able to outperform stock suspension.

Get the s2. The s2 will allow you to achieve the camber range you want with more caster (that's a good thing)! With the s1 you will be sitting at your alignment guys place constantly choosing camber or caster.

In fact, get the l2 that way if you choose to slam the car you can have the option of RCa plate to fix roll center.

On my 3-4 days experience , I couldn't agree more!!!

 

PmD them just now.

 

FYI, here's my P/N

 

yes this is the s2

 

Again, there is no such thing as a J's front roll center adjuster without camber offset. You have the S1, which is a less aggressive of an offset than the S2 you saw in the picture posted by another user.

The information you listed about the J's S1 joint adding 2-3 degrees is also incorrect.

Here is the S1 joint:



Here is the S2 joint:



It isn't that complicated.
