    Great product

    I got the br series for my q50 and the ride is pretty close to stock and I enjoy the ride height.

    Bc Coilovers

    I just dumped my car with Extreme lows and swift springs. I absolutely love it, it gives me more of a connection with my car, the coils are very smooth.

    So far so good

    These coil overs were easy to install and everything fit perfect. Just be warned that you will need to take off your stock strut plate from your old suspension & add it to your rear bc’s. Even came with some damping adjustment extenders that help a lot with my q50 because the top of the strut is bolted away behind the seat. So fair they ride amazing & have no complaints!

    BC Racing coilovers.

    I ordered extreme low BC Racing coilovers with swift springs, I was excited but also bummed out due to the fact that on the website it gave a warning that special items such as the extreme lows might take around 3 weeks to be shipped out. Come to my surprise only a week later my coilovers were delivered to the front of my house without any issues. Definitely recommend these guys if you’re looking to get quick shipping and an overall great experience.

    High Quality, Fast Shipping, Great Service

    Heads up for Q50 owners (RWD) - for the newest version of the BC Racing coils (extreme low in my case), you have to utilize the original top mount of the stock rear strut on the new coils. We also don't get adjustable camber plates since our suspension system is unaffected by that setup. The coils were well packaged, high quality, and came with a signed card from the person who built them to your specs. Package arrived a day early too! Communication was fast and friendly with all the staff here and I definitely recommend supporting these guys.
