What made you choose this particular product?
The first owner of the vehicle installed these once the stock struts were giving out.
Is this your first time buying from this brand? Did you consider other brands?
It would have been.
Was it easy to install? Any installation tips that will help others?
I bet it took some elbow grease, but nothing too crazy.
Once you've had a chance to use the product, did it meet your expectations?
It's great being able to easily adjust the dampening of the 4 struts by simply going under the vehicle and turning the dial on each strut. No need to pull the struts out or get inside difficult compartments of the vehicle. The difference between the softest and stiffest settings is truly remarkable. It completely changes the feel and handling of the vehicle.
Any additional comments?
These are excellent struts for the daily driver who wants weekend tractability without missing out on comfort the rest of the time. There are definitely better struts out there for the track, but they will not be this versatile.
