UPDATE: after spraying my inner fender area with some undercoat, to cover the area I hammered back to clear tires with ncrca's & 2.5 degrees caster I notice I AM rubbing on the inner unibody frame rail on both sides at full-lock with the p/s knuckles.

So, in other words. If you run p/s knuckles you won't need a BV kit or aftermarket (ueo/jic/etc) tie rod ends, as it wont help you get more angle. Or atleast without some super wide offset rims, or really far out there adj. control arms/ncrca's

UPDATE 2: just an FYI, aw11 rack housings are the same as the ae86, the only difference is the aw11 rack 'pinion' gear shaft is 1 inch longer and doesn't need the column extended as far as the ae86 rack & pinion gear. (NOTE: if you swap the quaife qsr into the aw11 rack it would be the exact same as an ae86 rack equiped with a QSR)

UPDATE 3: From my posts regarding manual rack/qsr on club4ag regarding column extension/adapters

--------------------------------------------------------------------------------

I just took a quick measurement, there's an extra 1 1/4" of shaft that should be inside the column extension.

Some quick math on the differences in ae86 manual rack column & intermediate shaft differences = 3.825" extension would be perfect. (just a hair under 3 53/64" which is the combined difference between the total lengths of the manual & p/s column and shafts.)

So if you were going to weld to the column/make and adapter: I'd just round it down to 3.75 - 3 3/4" for the extension if installing a quaife qsr/oem ae86 manual rack

Subtract 1" if using an aw11 manual rack.

AW11 is the same as AE86 rack housing?? noice!

in all these pics, the clean rack housing is the manual AE86 version??
thanks for the writeup

from the pics, it looks like the rack is the same for both LHD and RHD. The pinion is opposite direction though from what I can see.

RHD Rack against stock


RHD housing


When I was searching the US Quaife racks were so much cheaper compared to RHD models If the rack breaks, maybe there are cheaper replacements in the US...

god that looks very similar to my escort quickrack!

Its a bit harder to machine extra teeth into a ps rack as you run the risk of going too far into the high pressure zone and causing leaks dont you? I think if i had a hachi i would need PS as i had trouble drifting one with 12deg castor

I think i'm going to go with one of those multiplier boxes on my cressida one of these days...and maybe shortening my steering arms, basically removing ackerman and making the car useless for anything other than opposite lock haha.

Yes.

I agree, that's probably why they went with straight cut teeth, that way they could make the LHD & RHD options cheaper and only have to have to make different pinion gears.

Well, of course it would look similar. I mean, how much room for different designs do they really have?

I wouldn't even bother trying with a p/s rack, I don't think you can due to the design (not 100% sure on this). Some 5-7mm spacers (depending on how far in the seals are on the rack and how far they will sink into the rack housing before binding or coming off the pinion gear) on each side and shorter steering knuckles are the way to go when you want more angle on a p/s rack.
