I don't think you're going to get anywhere near 5-6 deg nor would you want that much if you plan to drive on the street. I expect that much camber would compromise braking as well.

As I said above, I have the Megan Racing version of those and was able to gain ~1.5 deg.

wow really, maybe i have to look into the buddy club one instead, i know the prices are pretty comparable between megans and buddy club roll centers

I would use a ratchet and very slowly work it out, going 1/2 turn out 1/4 turn back in DO NOT force it. This will take some time but will save you problems (ask me how I know). Once you get it out replace it, then loosen/tighten them all back to spec.

To be clear though that bolt needs removed/replaced, I would not just try to tighten it back in, IMO that will cause more issues.

As as far as your actual alignment you start loosing caster after around -2.2 on a normal S2k, so anything more and you will need aftermarket ball joints. I have the Buddy Club and like them.
yea im most likely taking the car back to the shop that did my clutch job to fix the sub frame bolt issue, but i dont think it should have impacted alignment by that much to the point where i couldnt adjust it past -1 camber.

not sure if it's the 19mm bolt but it's the one i circled in red, you can see there's a little gap where the bolt is not fully screwed in to mate the surface

what was your max camber after the roll center install or the additional -1.5 was the limit?

The offset ball joint added a fixed 1.5 deg. There is no adjustability in it. I'm not sure why the manufacturers suggest that you could gain more than that. There just isn't enough offset.

The alternate approach is to replace the upper ball joint and some of those are adjustable.

Hard to tell from your picture but I do not think that is the one. I would stand over their shoulder and make sure they do it like I suggested. If that thing is stuck in that position it could break if you are not careful.

The picture I used is from the Megan racing website. You don't need the spacer with the stock suspension. Mine came with the set which I only installed after I switched to coilovers.

interesting, im doing a little research looks like with J's you are able to get 2~5 degrees of camber adjustment depending on your ride height

haha yea, the shop is off this thanksgiving week, guess it will have to wait , but will definitely get it fixed properly. i m doing some reading on this topic as well, looks like billman also recommend using some penetrating oil, and front passenger side seems to be known for this issue or similar issue

That's probably about right. My front is at 3.2 deg with only a 15mm drop. When I first installed Ohlins it was lower and gained nearly a full degree. A more aggressive offset might gain that final degree.

That said, I've found 3 deg is probably about the upper limit for the street. With 255 in front, there is noticeably less steering feel and the car likes to track ruts. I imagine braking performance would be degraded too. I would dial it back if I didn't track it.

yea, i am aiming for -3 to -3.5 for fronts. i am running 255 17s square set up as well. i did notice a heavier steering feel after changing to sqaure set up. my car is mainly a weekend car and will occasionaly see track time so i dont mind the aggressive setting.

Did you figure out why the passenger side only can get 1 degree? I am facing something similar now… I checked the subframe and it seems not shifted .
