Do you have the racing version of this. I am looking for the HR605S-10200. I believe QA1 just went from 12" to 10" and I have not seen the part anywhere but Qa1's site. If not, can you get this?


  • This is the only version of the QA1 Single Adjustable Front Coil-Over Conversion that we offer at this time. Unfortunately we are unable to special order products that we do not list on the website.

Coilover Ride Height? How much adjustability do these coilovers allow for ride height specifically?


  • From 1" below factory level down to 3-1/2" low. Longer settings allows for softer ride within limited spring flex of 175lbs and adjusted shorter will compress spring rate limiting spring flex to minimum. Resulting in more tire bounce on rough road surface, but supreme grip and performance on newer smooth road conditions.

    Great Strut

    QA1 makes a great strut. The issue that I had is the spring is too long and the spring rate is too soft for my application. I completed my install with a set of 375lb 8" springs.

    Qa1 coil overs

    So to start my review. The picture that am show is not the correct parts you will get. The ones pictured use a 14" spring and do not have sway bar mounts. The ones you will recieve use a 12" spring and do have a sway bar mount. I drag race so my sway bar is gone. I was expecting to get the ones with out the mounts. Also I was expecting these to be assembled. They come in pieces that you have to put together. Not a big deal but add that to your install times. The instructions for installation suck. I had to go to a mustang web site to get help. Other than that as always fast shipping great prices!!
