    Great upgrade from stock 1 month ago
    5out of 5stars

    I have a 2002 JDM STI and waited for quite awhile before I took the coilover plunge. I had already installed Anti lift kit and front and rear whiteline swaybars but after my last power upgrade that was not enough to keep the car stable at higher speeds. After extensive research and opinions from a few who i knew had gone with this particular set i purchased mine. I got them installed and corner balanced along with whiteline upgraded front and rear endlinks and can I tell you it made a day and night difference. It was tuned to the last setting before stiff for comfort and it gives me so much confidence and control. The car is now back in balance. Modifying a car can be such a complex decision if you plan to do it correctly. Every mod has the potential to throw something else out of balance. Almost any mod you start with will require you to mod something else to regain the cars complete balance. I have only had mine on for a few months so I will see how they hold up, but thus far I am sorry I didn't do this when I did the swaybars. I live in an area where the road are notoriously bumpy and pothole riddled and these are doing fine so far.

    I could not recommend these more. If you're on the edge about spending 1000 on coilovers IT IS 100 PERCENT WORTH IT. These feel just like stock suspension. I had raceland on before and I was living the rough life. Now i got these babies on and it's as smooth as a babies bottom. 10/10

    Coilovers on my 2002 Subaru Wrx wagon  1 year ago
    5out of 5stars

    Overall satisfied with the coilovers. My brother had these on a scion and a civic so I knew they were going to be great. They fit like a glove I didn’t even have to adjust them . They came at the ride height that I wanted them.

    Huge amount of quality- very little price  1 year ago
    5out of 5stars

    Amazed at how much these Coilovers have to offer in way of agressive/track driving while still retaining comfort on the street. They feel and ride like a $2500-$3000 Coilover at 1/3 the cost. 10k miles and holding strong. HIGHLY recommended
