I have a factory ZF 2.5 turns lock to lock steering rack with factory turbo tie rods and boots installed. The rack has less than 15k miles(total) on it. It was built by ZF this way. Not a gear change with aftermarket parts.
Your steering rack should be the stock 3 turns lock to lock. Installing mine with dramatically tighten your steering responce. Even more so at higher speeds.
I will sell it complete with outer tie rod ends for $600.00 + shipping . Of course you will need to find out if this will help your needs. Im assuming your mechanic checked out the front end components (ball joints, tie rods, etc) and nothing is worn.
If your looking for a cheaper way to tighten it up just try a 330mm steering wheel.
