    hi guys,

    okay I need to have adjustable rear camber for my C32 laurel. I've tried contacting R31 house about their adjustable control arms but have had no luck so far (as far as I can tell it's the same IRS rear). The car isn't on the deck (it's not far off mind) but the rear is running a whopping amount of negative camber (easily in the region of 8-15 degrees).

    I'm going to raise it for now to save me getting more police bother, but surely there must be a solution? I noticed some aussie R31's slammed on the ass running near 0 on the rear so it must be feasable.

    Nah the control arms are those big wishbones bud - It's a fixed setup, you' need to incorporate some adjustment onto the inner mounts of the arms.

    OK! After a day of research, I got five viable solutions -
    1) The aus skyline r31, VL (and by that ill also assume the early C31 laurel) had a live axle. So no matter how low you drop it it stays 0/-1 deg camber. Con - the fitment appears to be all different, has a weaker diff, and will require some fabrication to fit.

    2) Buy R31house rear camber adj. control arms - which I would consider if they would acctually get back to me. Easiest and only bolt-in solution, but most expensive I should imagine.

    3) Slot the rear outer control arm mounts and put in an Eccentric/cammed bolt to adjust by perhaps 1 deg max (not really sufficient in this case)

    4) A guy in Trinidad has sent me photo's of his jig and process for installing an S13 rear cradle/subframe. Essentially nothing more than 4 new mounting points but it's the location of these that has to be very specific.

    5) Guys in Aus have started doing R33 rear ends on the similar VL Commy - similar work to above, either in the UK is a viable option as still enough R33/S13 spares going around cheaply.

    4-5 seems like the best option unless r31 house gets back to you.

    To be honest... just by looking at it - I don't see the problem in grinding off and fabricating new tabs on the beam where the control arm mounts.. the way the coilovers are there's very little squat on load
