AE86: RA60 + MX73/63 Lower Arm Lenghts

Hey Ppls,
Just thought this information might be of interest.
RA60: 300mm
MX73: 310mm
MX62: 350mm
These measurements are from the center of the ball joint to the center of the pivot point on the opposite end.
Im currently using RA60 struts and lower arms (P/S variety) in my AE86. And I have +0.4deg camber. I will be putting the MX63 arms in so I ill post the camber I will have then ;p
Also to use RA60 ball joints in the MX73/63 arms the hole needs to be reamed out with a morse tappered reamer. But the MX63 steering arms might fit and are of the P/S variety too...
Ill be posting the results next thursday/friday.

Hey Necros where is the MX73 that you are getting the control arms from , Im after the rear brakes including the hand brake.
Thanks Damian.
Just another point to add MX32 arms are some between the length of 63 and 73 arms.

Is this for real Simon?
Is it safe to assume you have Sigma arms in your AE86? Were they an easy fit?
Cheers

as i beleive... when u use the ra60 or 65 front struts and and discs it gives u the positive camber... so that plus sigma control arms should give just a nice - camber.... just changing the sigma arms gives way to much camber i rekon

well as i have adjustable camber tops i can dial in exactally how much i want, but i think ive got a reasonable amount and not overly excessive, wet braking is somewhat less that the only downside.
yeah the sigma arms bolt straight in with some very mild trimming

Sprinta: Most engineering paces should be able to do the reaming for you... Im not sure where you can buy the actual tool from.
DJ345: I bought my lower control arms from EKW, there a bit expensive but can get a lot of parts too...
Simon-MrRx7: Do you know what model Sigma your arms are from? I measured some on a sigma (not sure what model) at my mechanics and the arms were only 300mm long, the same as RA60... I.E. Not much good with RA60 struts.
