Why can't I get more than 3.25* of camber with CasCam and eccentric bolts?
 

My car has SPC eccentric bolts in the upper holes of Bilstein B16 coilovers. It also has new Raceseng CasCam plates. But the most camber I can get on one side is 3.25*. The other side is better, but still only 3.6*. Why? I'd like to get 4 or more. The Raceseng website says I should be able to do that with ease. What gives? The experienced alignment guy maxed out the eccentric bolts.

Have you tried oem crash bolt upper + lower spc bolt and camber plates?

No. Although I've thought about it. I'm hesitant to run two eccentric bolts on the same corner of the car.
I would like to figure out why I can't get there with the existing hardware before adding other parts.

Factory coil diameter? Perhaps the coil is hitting the chassis? Last time I lookup up there, I remember thinking that might be a possible concern.

That is not the case. I've seen 3.6* of camber on both sides with these coilovers previously. That was when I was using different camber plates that supposedly don't offer as much camber as the CasCams.

I'd shoot an email to Jarrett, my only thought is that most aftermarket dampers are slotted/enlarged holes to allow for some more camber, the Bilstein is one of the few that aren't and the marketing copy went with what the average user would get instead of the edge case. I only took mine up to about where you are now with a single cam bolt and the raceseng plates. iirc I never maxed them but -3.6 maybe up to -3.8 was all I was going to get without getting a second cam bolt in there. Good luck, fwiw I put maybe ten thousand miles on two lobed cam bolts without issue, currently on a strut with a slotted upper hole and a cam bolt in the bottom hole also no issue at -4 for the past year and a half.

Wait, have you moved the screws over to get the top plate slammed to Max negative? Take a picture looking right down at it. Should be able to go to the last white line.

Edit from the ad copy:
The combination of the camber bolt and slotted coilovers can yield -4.5° of negative camber gain.

@Pat, with only one camber bolt (I had mine at bottom) with cascam maxed out on B14, I was able to reach around -3.4. With both camber bolts in both slots + cascam, I was able to reach around -5 or so. I have been running camber bolts in both slots for a while now with no issues. Sold my cascam, so right now with both, I'm running around 2.4-2.5. Also, how are your tires. Tires do have an effect on the camber. When I had new tires, it was giving me roughly 0.2-0.4 more negative camber compared to now.

Thank you for the feedback, Bach415. That's helpful. My tires are nearly new. But now I'm more inclined to get a second pair of eccentric bolts.
I wonder if there is something about the Bilstein springs that limits camber more so than 60 mm springs. I don't think that's the case, but I suppose it's possible.

I can't tell you for sure if the stock progressive springs are limiting it since I am running 60mm linear springs on the fronts for the entire time I have had them (fronts are revalved and also it was purchased off a previous owner that way). But I have been running this set up for roughly 30-40k miles already and have never ran into the issue of the bolts slipping or losing camber. Car has been tracked before as well (not often since it's DD).

Have you tried loading the spindle before tightening everything? I was able to get -3.2 on one side with stock dampers and 2 sets of camber bolts. Maybe you can get another 0.2 or so to match the 2 sides.



That, and maybe drop it another 10mm or so lol

Check here, I think you have the same problem as your Bilsteins run huge progressive springs and you’re hitting the caster adjusting plate bolt.

I have not tried that. I don't know if the alignment guy tried that. But getting another .2* isn't going to make me super happy. I'd like to get another 1*, but would be content enough with another .5*.

Thanks, Marco. Great info! The top of the plate clearly goes all the way in. If this is indeed the problem would that still be possible?
