Honda Civic Si Performance Parts and Mods

A great all-around performance car, the Honda Civic Si provides a high level of fun without sacrificing the comfort and fuel economy you’d expect from your daily runabout.  Because the Si is in the middle range performance model for the Civic line it has great potential for aftermarket performance upgrades.

Honda is known for its amazing shifters, but with PERRIN Performance aftermarket shifter mods you can get your Si’s shifter even closer to that notchy race car feel. Pair your improved shifter bushings and adapters with a weighted shift knob for a complete overhaul of your gear rowing experience.

We also offer new suspension upgrades, like a precision-made strut brace to help tie the front corners of your car together, reducing flex under load.

Make your Si stand out from the crowd while you’re rolling down the road or parked up at a show with our exterior accessories and upgrades. Tow hook upgrades replace flimsy OEM examples and license plate relocation kits clean up the look of your grill and bumper.  Wheel fitment can make or break the look of your Si. Our wheel spacers are milled to fit the Si hubs and help push your wheels to the outer corners of your car. Fill those wheel wells and add road presence to your Si!
