What is the difference between the single adjustable conversion kit compared to the double adjustable conversion kit? Is it worth paying the extra money to get the double adjustable kit or is it just a minor difference in performance?


  • For the QA1 Double Adjustable Front Coil-Over Conversion - 200lb Springs (05-14 All) the valving between compression and rebound can be adjusted completely independent from one another rather then the single adjustable coil overs only has the one point of adjustment.

Question Resolved

how far can they lower a '13 GT? I want to know how far these can lower a new GT and how harsh will the ride be compared to Eibach Pro kit springs (which are in the car now)? thanks, Bob


  • The QA1 Double Adjustable Front Coil-Over Conversion - 200lb Springs (05-14 All) can lower your car up to 3". Since these Coil-overs are adjustable, you can make your ride as harsh as your Eibach springs, you can make less stiff, or even more stiff than your springs. These Coil-overs will ride a lot different than lowering springs will. These are meant for full adjust-ability to really dial in your suspension.
