    Post Lower Control Arm- Measurments & Compatibility

    Ok guys

    im still confused with a few things

    i found a list of LCAs and what sizes etc...
    Model - Length - CT Dia
    RA40 - 300mm - 12mm
    TA22 - 300mm - 12mm
    AE86 - 300mm - 12mm
    KE7x - 300mm - 12mm
    XT130 - 310mm - 12mm (RT132 too?)
    MX73 - 304mm -12mm
    MX62 - 365mm - 12mm
    GE Sigma - 330mm - 12mm
    S13 - 350mm - 14mm

    now it seems everyone goes with the XT130s what i want to know is if i do the same what exactly do i need to do the job, what parts do i require i know i need the XT130s but what else and has anyone one done a write up fo this?

    thanks

    nothing else.

    the xt corona has lock stop on the lca. you need to cut these off. thats it. your stock tie rods and rack ends will have enough adjustment in them. if you have power steering as as well though, you might want some longer tie rods or rack ends.

    you can grab the tie rods off the corona as well. theyre a 2 piece turnbuckle design, and have a greater range of adjustment, and are on car adjustable too.

    if your tie rods you have on your car are new say, but your stock rack ends are fucked, just get ra60 rack ends. theyre a touch longer.

    either set up will be long enough.

    also xt/rt 13X are all the same.

    no. i would only use mx62 arms if you want full "oni kamu" style. its really too much to work properly. youre talking in the region of a minimum 6 degrees negative camber. maybe 5 ish with strut tops wound full positive.

    mx62 would only really be good to cut up into adjustable ones as you have more meat to play with and would likely be bit thicker and stronger than other yotas of the same style lca

    Agreed. I have them on my RA65 and it's heaps of track. I run 14x7 0 offset with about 4-5deg neg camber so they sit under the guards.. Will be going s13.

    thought i'd add.. people asking about mx83/gx8#/jzx8# lca's .. they have a larger bolt through the pivot bush. (other end to the ball joint).

    and could the OP please update the first post so the list is corrected?!!

    re ball joints.
    A6 celica/carina *4cyl* have same ball joint thread and taper as ke3/e7/tt132/ae86.
    ma6/ga6 celica-supra 6cyl have a larger taper but with same 14mm thread. mx8#/jzx8# etc have a larger taper ball joint than the ma61.

    compared these moons ago.
