Anyone ever heard of one for a 6th gen, or anyone ever try and make one using rack/pinion gear from another vehicle?

Yeah, I do have a spare rack.... but it's not very simple to just modify. The gearing has to be changed, which is built into the rack and pinion.
Unless i found a replacement that fit, not sure it would work. -------------------- -93 Rx7, Turbo 6.1L v8, 725rwhp/760rwtq

Could you not remove the OEM piece from a spare, weld it over and then recut it?
If not, should be able to have it machined pretty easily out of a blank and then rethreaded on the ends. OEM vw piece on the left, Quick on the right.

You will have bumpsteer issues if you put in a different geometry rack out of another vehicle.
I forgot the exact details but the tie-rod length has to be specifically proportional to the control arm length. If its too long or short the wheels will turn toe-in/toeout when you go over bumps(bumpsteer). The tierods must also be on a perfect axis with the roll-center of the suspension or some other suspension geometry point(I cant remember). This is one of those things where the oem manufacturer knew exactly what they were doing when they designed it and without proper schooling all any of us can do is guess. The idea of modifying the gear ratio of the rack and pinion gear sounds practical, maybe not cheap though. |

i had once let someone drive my GT4 who had a regular celica, the first thing he noted was that the car turned alot more with the same steering input.
I hadn't really noticed myself as i had an SS-III before that -------------------- Mike W

AWD binds up anyways, but i think in general theres a reason why high speed cornering cars are poor at making low speed turns, like some kind of tradeoff
though no st20* celica has ever been praised for its turning radius, superstrut or not -------------------- Mike W

You'll need to keep the powersteering even with the 1.5:1 or your arms will get really tired by the end of a stage/session. I'm thinking about doing it to my Road Race Celica too. |
