The Eibach PRO-KIT 82108.140 is a four-spring lowering set for the 1.8L four-cylinder 2014 Toyota Corolla, and the manufacturer lists it at 1.3 inches of drop front and rear. Its progressive-rate coils are meant to lower the car's center of gravity while keeping the ride controlled, so this kit suits buyers who want a firmer, more planted 2014 Corolla 1.8L without giving up daily drivability. Compared with a stock setup, the lower center of gravity is the main handling payoff: less body roll in corners, less squat under acceleration, and less nose-dive under braking. The manufacturer also states the springs were tested with factory dampers, so you can keep your existing shocks and avoid the cost of a coilover conversion.
If you are searching for Corolla 1.8L lowering springs that work with stock struts, this set is built around that use case. The kit is sold as a complete front and rear set, and the manufacturer's install sheet says to keep the factory spring isolators, dampers, and tubing. The front springs and rear springs are different parts, so check the part numbers on the box against your position before installing. Eibach also recommends measuring ride height before and after installation and having the alignment checked once the car is lowered.
The manufacturer's vehicle search lists the PRO-KIT for the 2014-2019 Toyota Corolla Sedan and does not break out individual trim levels on that listing. Confirm your body style and engine in the manufacturer's application search before ordering.
Yes. The manufacturer notes the springs were tested with factory dampers, so stock shocks and struts are the intended pairing.
Yes. The manufacturer's install instructions say to retain the original stock spring isolators, dampers, and tubing and reuse them with the new springs.
The manufacturer recommends checking the vehicle's alignment after installing a PRO-KIT spring set.
The manufacturer recommends a hoist, which substantially reduces installation time, and says to keep the car properly supported on safety stands with wheels blocked. You will need a proper spring compressor, marker, and standard hand tools. For MacPherson-strut fronts, mark the upper perch orientation relative to the lower perch before disassembly, because the manufacturer warns that noise may result if the orientation changes. Install the springs with the Eibach logo facing up, and never use an impact gun on shock piston components or piston rod nuts. Before final torque, preload the suspension with the car's weight on its tires, then measure the lowered ride height after driving about ten miles so the springs settle.
