First, the Miata mod : http://flyinmiata.com/tech/depower.php?x=1 http://www.dsmtuners.com/forums/article ... -rack.html Second, how this stuff work : http://auto.howstuffworks.com/steering4.htm The solution, soldering the torsion bar : http://www.motoiq.com/magazine_articles ... -rack.aspx I have rebuild my steering rack and done this mod :   Add grease for rust protection only :  I'm in peace now

This post is amazing, first time I have heard of someone here actually welding the torsion bar. Good to know that this is the mod required to maintain direct input, with no slop, when de-powering a power steering rack spool valve. |

Especially to be more solid, imagine if the torsion bar break ! The power steering fluid help to keep pressure in the spool valve and the torsion bar work normally. Drain the fluid and you have a weakened torsion bar system. |

This is pretty cool, but miatas are all power racks hence the write up. It's a thousand times easier just to swap in a manual rack. |

The manual rack requires more turns to go lock to lock. For a drag car this isn't a big deal but it is noticeable for a daily or autocrosser. |

I am very aware of the gear ratios. It works out to be 3 full turns lock to lock for the power assisted rack and 4 1/4 turns lock to lock for the manual rack. I may do this in the future but since I just got an alignment it's gonna have to wait. Besides it isn't really that bad without the mod, I've certainly parked worse. |
