Suby rack

[wally57]

Guys sorry to be a pain, but after all of the feedback I got I have changed my mind about trying to fit a mx5 power steering rack and I am now looking for a suby rack. I want it to have 2.75 turns so what all the info on the site is telling me is it will probably need to be out of a WRX.

My mate has a brand new one in his garage, I'll check which model it's for

Hey Wally....I don't agree that you need a WRX one. I have a 1989 Liberty one in my car, and ONCE YOU SHORTEN IT TO THE RIGHT LENGTH, it is right in the 2.7 turn lock - lock range. If you get a rack with 2.7 turns lock to lock before it's shortened, you will find it's even faster when the right length....too fast for my liking....the car would be too darty for a road car.

 

In case you're unsure, the reason for shortening is to get the inner ball joint centre to centre length right (ie suit the spacing of the LCA inner pivot points) and also to get the rack travel right so you get the right steering lock (which determines amongst other things your turning circle)...if you left the subi rack at std length and travel, the bump steer would be wrong and the locks would be excessive, causing the wheels to foul the body at or near the locks. It's just a fortuitous coincidence that by shortening the rack about 11mm each end you get the centre to centre distance AND the lock travel within a bees dick of std 240Z, so it all works out nicely.
