    I’ve been reading about the camber plates for our cars. I’m wondering if anyone has tried the eibach or similar camber bolts? It claims up to 1.75 of camber adjustment.

    Camber bolts are inherently weaker than the stock bolts since they need to be thinner to accommodate the eccentric that allows for the extra camber adjustment.

    If you intend to track your car I'd think twice before using them.

    Thank you for the response. I’ve read about possible failures. My local mustang tune shop insists they have installed them on 50% of the cars they see including those that see serious track time without any issue.

    I was curious to hear of any where running them.

    Do you track with them?
    What brand did you install?

    Not sure what the torque specs are on a S550 but the later S197s required a torque specs of 166 lbs/ft. The clamping force is what keeps the struts on the spindle. Camber bolts have a much lower torque spec such as 75 lbs/ft.

    Kelly at BMR said he thinks the S550 is ok with bolts because the front suspension is more robust than the previous generations.

    I know of a car that runs both upper and lower bolts, which does see a lot of track time and they have not had any issues.

    With that said, I personally bought plates because risk mitigation on something this expensive, and fast, is probably a good idea. I have yet to install them though.

    I use the BMR bolts and Maximum Motorsports cambe/caster plates. And I track a lot.
    Together, I can get 3 degrees camber. works great.

    The S550 requires a torque spec of 166 lbs/ft. The clamping force is what keeps the struts on the spindle. Camber bolts have a much lower torque spec such as low as 75 lbs/ft but I think BMR requires 125 for their S550 bolts. Still, significantly less than stock.

    However, there may be another alternative

    GT350 Front Camber Adjustment

    Good discussion for the S197 found here:

    Why not camber bolts, you ask? - Forums at Modded Mustangs

    Ford themselves sell camber bolts for Mustangs. I used the FoMoCo ones on my S197 together with camber plates to get over 3 degrees of front camber. I haven't bothered with them on my GT350 because it doesn't need the big camber numbers that the S197 did.

    The S550 chassis uses M16 lower strut bolts and they're torqued to 185 ft-lbs, which isn't nearly as much of a "stretch" as 166 ft-lbs was on the M14's used in the 2011-2014 S197's. Ford also moved the lower strut bolts closer together on the S550, so that means that the bolt can give the range of adjustment without being ground down as much. That all said, I haven't seen a set of S550 camber bolts, so I have no idea if they're a good idea or not.

    What I did on my last S197 was actually to slot the bottom hole on the strut itself. That allowed me to gain some camber and keep using the stock bolts at full diameter. It worked like a charm.

    Decided to try the bolts. Couldn’t get much negative camber. Now looking at the camber plates. This is maxed out.

    Interesting the tires are heating up more quickly now. Pressure quickly rises from 32-35 within a few minutes of driving which would not happen before.


    Front
    Camber -1.45 & -1.36
    Caster 7.46 & 7.35
    Toe 0.02 & 0.01
    Rear
    Toe 0.14 & 0.18
    Camber -0.33 & 0.44
