    MX62 are way too long for normal use, and also their balljoint is alot bigger than AE86 so donøt suit the steering arm. Use them only for S13 conversion.

    Egg, RA60 struts give about 3 deg positive camber if run on a stock AE86. Sigma arms give around 3 deg neg camber when used on a stock AE86, so going Sigma and RA60 should give roughly zero camber. But if you are doing it I'd be interested to hear what it ends up giving.

    Using XT130 arms (also heard rumours RA40 are the same) I used AE86 rack ends, RA40 tie rod tubes and RA40 tie rod ends. So very similar, if not the same parts as Dan above.

    I just want to point out at least a few of the measurements in the top list are wrong. When you measure the effecting length of a lower control arm, it should be from the middle of the ball joint, the the middle of the bolt hole. The pivot point of the ball joint can't be measured exactly, so you have to imagine where it may be. Move the ball joint around a bit so you can get a better idea of where the centre may be. After doing this, I think the list would look closer to this:

    RA23/28, RA40, RT132/XT130 (all the same part) 300mm
    KE30, KE55 etc 300mm
    AE86, TE72, KE70, AE71 290mm

    I still need to measure this better.

    It would make very little difference to camber. If you wanted negative camber, you either adjust the strut tops, or additionaly you can get longer lower control arms. (Either Sigma but I havn't looked at them, or XT130/RA40 which are +10mm I think, or have the AE86 ones lengthened which isn't hard). Or you can also get offset RCA's.

    my last post was in addition to my first in this thread. im guessing

    ra60 struts +3, sigma lcas -4 (closer to -4 than -3 apparently), t3 negitive camber rcas -3 and play with the cambertops to get -3 overall.

    Also, RT133 are the same as XT130 / RT132 obviously.

    ST141 and RT142 are 290mm
