Description
Eibach's ERS line has evolved over the years to be the world's most prominent, comprehensive and superior Race Spring System. Eibach Race Springs are all manufactured in series production, often repeated, with a strong manufacturing experience. Thus, Eibach constantly achieves the most linear spring characteristic (rate) while maintaining the lowest tolerances and the highest quality in the industry.
However, Eibach products are anything but average. We know what we want from a vehicle. We want immediate response.
Eibach products are created to meet the extreme requirements of racing, from the 245-mph Mulsanne straight of Le Mans to the fender-to-fender combat of the Daytona Motor Speedway.
The chassis of a production vehicle is designed to be built at a minimum cost, and suited for an 'average driver'". We enthusiasts.

2022 SEL Premium - Daniel
Eibach always delivers
Put these on my Santa Cruz 2.5t awd with 235/50/19 tires and they ride amazing just a little firmer than stock but still a nice daily ride. Lowered it the perfect amount.

Great springs
Not looking to slame your car and just drop it enough to take up the wheel gap then these are the springs. Used eibachs on mynother cars and of course I'm not surprised at how they perform and make the car handle. More on the upper end in price but worth the money

Eibach Lowering springs
Drops the car about an inch all around for a great finish , look , and takes away the wheel gap. Also you can tell the difference in the ride taking a corner

Awesome product, makes the car look amazing! I have this paired with the ford performance track shock and strut kit. Comfortability is not bad at all, haven’t scraped on anything!
