Ok, here is some info. I used a tape measure so its not the most accurate measurments in the world, but they were measured with both steering racks removed so the measurement would be more accurate. I would say +/- 1/8"

ST204 (GT) Stroke - 5.125
ST205 (GT4) Stroke - 4.625

In a nutshell, the extra extention of the GT rack will not work properly with the Superstrut suspension. There IS a reason Toyota removed a half inch of stroke from the ST205 steering rack. Anybody care to measure the ST rack?

Thanks,

dude they are the same https://www.1sttoyotaparts.com/oempartscat.html

there is nothing special between the gt and st suspension. They are both the same lengths I can guarantee it, no need to measure They both use McPherson set ups.

You are correct, they are the same part number. I just called Toyota to confirm this. Which means they are both incorrect for the conversion.... Im wondering if the extra stroke would effect any of the joints? There is alot going on with the superstrut suspention and while the ST/GT steering rack may "work" I wonder the effects on longevity or increased chances of damaging a joint.

I wouldn't risk it if I were you. You might effect the full potential of the suspension. But who knows all you can do is try.

Well my LHD German ST205 Steering rack was installed and then removed due to a fracture at the aluminum casting. I used a standard rack to replace it (with the superstrut setup) to get the car on the road again. Well its all aligned and it technically has clearance issues. When its on the ground its ok... the tie rods clear the frame/unibody mounting position by a HAIR! But when its in the air it wants to bind very little on the frame at full lock. Honestly the chances of the car being fully turned while hitting serious enough whoops to make it hit anything is slim, but not good enough for me. Im going to be machining some custom inner tie rod ends to allow the use of the ST205 outer (curved cast iron) tie rod ends for full clearance. I also have some interesting information to report on these steering racks (LHD German ST205, RHD JDM ST205, LHD USDM ST204). Ill gather up my info and post back a bit later.

Thanks,

update. also any luck on those custom end tie rods?! for other members
