MX73 strut into AE86

[terryo]

RA60 & RA40 are definitely different in the bolt spacings for steering arm mount. RA60 give you better brakes. You can swap the hub & rotor from RA60 to earlier RA40 strut, but custom brake brackets needed. You can use the RA60 steering arms with a bit of mucking about. There are KPI angle changes between the various models which effect camber. I've found the RA60 is the same as AE86 (8:50), but I've not measured all the other ones. I know the KE series have a 4:30 KPI so you need a 35mm shift with longer arms or altered strut tops, or a combination of both, to get back to stock camber.

Hey guys ive been reading a fair bit on these forums but i think this will be what feels like my 1st post..

im doing the R32gtst front and rear brake conversion in my KE70.

ive been out done some measuring, and anyway got stuck on steering knuckles.

So im getting some made up, they have the 90mm spacings to suit st141 and mx73 struts.
and 86 ball joint.

if anyone is keen i can have some more made, PM me if interested.
same specs as 86 PS arms. but 90mm spacing for strut.
