Rides slightly on the firm side and will get bouncy from higher spring rates. Slightly expensive for not being rebuildable, or dampening adjustable. Overall pretty good.

If you plan on slamming your car these are not the coilovers for you.They get extremely bouncy when you lower them to the limit but if your looking to Daily your car and you want a 1.5-2" drop then these are not a bad choice for you

This is my first set of coilovers for my car, never driven a lowered car before. As the parts were being shipped I did my homework and read up on the install provided by Progress. The only reason this coilover gets 4 out of 5 stars is that the instructions were really vague. There are many components that come in the kit, and it wouldn't hurt to better label what and where things go. During the install the most challenging thing was disassembly of OEM suspension, it took the most time and energy (having 130K miles on my chassis). Assembly of the new Progress coilovers is do-able, but again having better directions would make it reassuring. You are dealing with you cars suspension, it is under tremendous and dynamic loads while driving, the last thing you want is complications while you are driving. Finally ride quality is great, a lot less body roll, and the bumps from the stiff spring rates is very tolerable for daily driving. With OEM rims and tires I have 1 inch gap in the front with more to go, and I am fully tucked in the rear with more to go. I would recommend these coilovers, get the proper tools for the install, and be sure you all the necessary honda parts!!

Tough decision, but glad I chose these

It was between Function & Form Type 2's and these, and I am so happy I chose these coilovers. The adjustment allowance is enormous, and I am able to drive smooth, slammed and sexy on 17" wheels. Great ride, great product, great price.
