The ride height is perfect, car rides and handles so much better than stock. Those springs are the truth. Thank you.

Review by Graham P. on 13 Apr 2018 review stating Excellent quality springs that fit
Excellent quality springs that fit perfectly, provide better handling without sacrificing ride comfort, and sits just low enough to eliminate most of the wheel well gap. Definitely recommend!

Review by Wayne M. on 22 Mar 2018 review stating After the install I had
After the install I had some reservations based on how the car drove and felt. I was initially disappointed and wanted to go back to the factory springs. After 2 weeks things have gotten so much better! The ride has improved significantly and the handling is great! I'm giving a revised rating of 5 stars!
Thanks again David for providing another great product!

Hi Wayne,
Happy to hear that after driving the car and allowing the springs to settle a bit, that you are now happy with the ride quality. Appreciate the kind words as well. Look forward to working with you again in the future.
Thanks,

You Definitely Get What You Pay For!
Review by Reflantrn on 14 Jan 2017 review stating You Definitely Get What You Pay For!
Installed these this afternoon with the help of a friend. After watching the Youtube vid, we started wrenching and were done within 3 hours without air tools. Install was easy and straight forward. No issues whatsoever ( well I did forget to initially torque down a couple of lugs). Once off the jacks, car sat crazy high, but after a couple of hours she sat perfect..
Handling? NIGHT and DAY over stock. Mash the throttle and front end goes forward, not up in the air. Brake dive is gone as well. No more Caddy lean around corners. Rebound over dips and imperfections is swift and well controlled. No more front end wandering at high speeds. Fender gap is perfect, almost what you might expect from BMW. Drop appears to be right at 1 inch so far. Did not want any more than that, as it's my daily, and I drive all day. Steering feels more precise, which might be enhanced by the Luxon FSTB (yep, you will want that too).
Thank you Dave for fast shipping and answeing my NOOB questions.

FANTASTIC!
Review by Lance K. on 12 Jan 2017 review stating FANTASTIC!
Installed the springs over the weekend on my 2016 Optima SXL and I could not be happier!
They ride as smooth as the stock springs did, lower the car just enough to get rid of most of that pesky wheel gap without causing you to scrape on everything, and were very easy to install.
Watch the installation video to get an idea on how to install them if you have any reservations, it's very well put together. (This can be done using a floor jack and jack stands as well.)
