If you live for the corners, the Eibach PRO-PLUS Performance Handling Package delivers. Eibach PRO-PLUS packages include the legendary Eibach PRO-KIT springs along with matching ANTI-ROLL-KIT sway bars. The Eibach PRO-KIT lowers your car's center of gravity, reducing squat during acceleration, body roll in corners and excessive nose-dive under braking. Add the Eibach ANTI-ROLL-KIT sway bars—with increased roll stiffness, compared to stock bars—and you get pure, balanced-handling perfection. 



With the Eibach PRO-PLUS installed you will immediately experience more-precise turn-in response, improved handling, and enhanced cornering grip—in any performance-driving situation. The Eibach PRO-PLUS is designed and tested to work well with either factory or aftermarket performance dampers.

Sway Bars

I installed the springs and the sway bars. I reviewed the springs already. Long story short if you have Impact wrench/driver this job will go very quickly even if you’re on your back. The rear sway bar is very easy, with minimal bolts to remove. The front sway bar is a bit more time consuming as you will need to remove the brush guard and a metal mount that covers access to the sway bar. These sway bars made a phenomenal improvement in performance. There is next to no sway I can feel now. Overall the springs and sway bars combo took nothing good away from the performance and comfort. This kit added a great improvement to looks and handling.
Installed on a 2021 WRX STI, stock rims/tires.

Joey,

Thank you for the 5 Star Review and added pic! The Eibach Pro-Plus Lowering Springs/ Sway Bars Combo Kit for the STI is a fantastic suspension upgrade from OEM! Without a doubt installation is easier when you have the proper tools!

Eibach Pro Kit

I haven’t installed the sway bars yet.
I installed the lowering springs. The installation on my 2021 STI was easy however I had the right tools. You’re going to want a hydraulic low profile lift, 4 jack stands, impact wrench, sockets, socket wrench, torque wrench, plastic fastener remover tool and spring compressors.
Follow the included instructions on trimming the rear strut bump stops. My STI isn’t bouncy, doesn’t bottom out, isn’t a rough ride and with stock rims(19”) there is no need for spacers.
Also for my fellow mudflap people; I have the full size RokBlokz and have plenty of clearance.
Overall the STI looks great lowering it. As for driving quality I wouldn’t say these lowering springs do anything to blow you away as in “Woah man this car is soooo much better.” However they don’t take away from the ride.
