I just had some eibachs installed and I went to PTuning in Manassas.
They specialize in import cars but also work on euro cars as well.
They did a great job with the installation/alignment and Follow Up.
They are a race garage so they don't cut around corners and the fee's
are reasonable compared to RRT. They share the same passion when it
comes to cars rather than just a maintenance/repair garage.
Great installation, alignment and full dyno facility IMO.
