you don't need adj arms to fit traction brackets!! fitting traction brackets with the factory arms will work fine, if you have traction bracets like I have fitted which have 3 sets of additional holes then the location of the standard(if standard arm are fitted) would effect the pinion angle! If I select anyone of the three holes then I start to adj my pinion angle(I do have cusco adj rear arms fitted btw) by quite an amount!!

i think you misunderstand me.
yes. you can fit the brackets with the stock arms.
yes. if the adjustment holes are not in the correct arc so as to not affect the required lower arm length, the pinion angle will change.
it seems logical to manufacture the brackets such that the original lower arms can be used, but then you wouldn't have to buy new adjustable ones would you Razz

...

i do not understand your comments above. first you say "fitting traction brackets with the factory arms will work fine" and in the next breath you say "If I select anyone of the three holes then I start to adj my pinion angle by quite an amount"
are you saying it is fine to have funny pinion angles when using the standard arm??? please rephrase Confused

which suprises me when you say 'no one in their right mind would just fit the brackets without adj pinion angle'.....that's what they do!!

let me rephrase.
no-one who knows what they are doing, would fit traction brackets without restoring the pinion angle to a suitable angle. from the designs of brackets around, this requires longer lower arms. i'm not saying that stock lower arm with badly made brackets does not change the angle... i'm saying why would you fit them and not restore the angle.

Quote:

fitting traction brackets with or without adj arms WILL adj pinion angle there is nothing you can do to stop that....unless you fit longer (you mean shorter??) upper arms(like I have!)or wind your lower arms right out!! With a standard lower arm as you move to a lower hole on the traction bracket the hole becomes further away from the lower arm, because the top arm is shorter, the whole lot pivots around this, you must therefore push the diff forward to get the lower arm in, which raises the pinion angle.

so you are saying that to maintain/restore the pinion angle, you must use longer lower arms??? which is what i said...

Quote:

I understand by changing the angle of the arm you are affecting squat etc etc but you just can't get away from the fact that fitting traction brackets with or without adj lower arms will affect pinion angle, oldcorollas have you ever fitted these???? because the amount you have to move the diff forward is quite alot! and I'm sure I wouldn't want to wind my cusco arms out that amount!!

so your cusco arms are too short.. whats the big deal.. get longer ones Wink

i'm not saying it has no effect. i'm saying (again) that to INSTALL THEM CORRECTLY, you need the CORRECT LENGTH LOWER ARMS..

Quote:

at the end of the day fitting traction brackets with standard bottom arms will work and will change the pinion angle by quite an amount.

is that a contradiction? are you saying that the greatly changed pinion angle works?

you say that the standard lower arms work...

and then you say that they will greatly affect the pinion angle..

so which is it? the new weird pinion angle is correct? or the use of lower arms is suitable?

not trying to start a shitfight.. i'm just confused by your contradictions.. and the bodgy design of these products Wink

... must be an AE86 thing Razz
