    so talking to some of the boys here and seems to be that their is some unknown mistery about our manual racks.

    heres some info ive been able to gather by having an Ae86 GTV rack and Standard Rack side by side

    different types: Manual racks

    Factory

    1. GTV
    2. Standard

    Part #'s

    1. ER2 - 40
    2. ER1 - 10

    Turns Lock to Lock:

    1. 3.6 / with AJPS Lock spacer - 3.9!! will massive angle
    2. 3.3

    Distance from case end to Rack end (see pic below)

    1. 156mm
    2. 144mm

    Aftermarket:

    Quafie


    *the part number is on the drivers side mount.
    *Turns lock to lock were measured with the racks on the floor, marking a point and counting turns of main input shaft
    * the noticable difference was once both rack were at full lock the amount of travel was visuably noticable as u can see above (case -Rack end distance mm)

    pics to explain below

    So the sportier rack is slower than a normal one? Is that right?

    The AJPS lock spacer fouls a little on mine to. it fouls on the internal bush on the pax side but i think it should be right after a little driving.


    as for the racks some guys say that the GTV has a better ratio. i dont know about that, it has more turns lock to lock and more travel than a standard aus spec rack.

    with my 14's up front , the GTV rack and the lock spacer i can't achieve full lock because the wheel hits the rear inner of the wheel arch, i think its actually hitting the break line bracket

    i think the lock spacers were missmachined...

    i got dave to send me a second one thinkin the first one was just accident/oldstock or something.. but both were the same...

    2 minutes with a file worked it out.
