Garbage.
I have bascially zero interest in modifiying my Versa other than the stereo and speakers which I have already done.
My long-term interest has been in my Honda Accord that I have had for 8 years now. When I first got it I bought all of the stupid cheap ass eBay special stuff that I thought was good, cool, and was a good value for the price. Looking back, a large majority was nothing but crap that was considered "rice". I regret buying those stupid parts and wasting the money on them, the time and effort installing them/modifying them to fit, and then the time to reinstall quality parts. After spending a few grand....on the low side probably my car is now in a state that I enjoy with high quality/expensive parts. But, it nevers ends....i'll soon need to fix some mild rust that is forming and once I get a garage I will actually be able to swap in a k series, build the motor, and add a mid size turbo....in addition to a multitude of other things.
My point is that you don' have to buy super expensive parts but the cheap parts will actually cost you more in the long run as they have me. In addition, use some common sense and don't believe any of the HP/MPG gains advertised on eBay no matter if it is a Chinese copy or a big name company.
If you still don't believe me I invite you to go on to Honda-Tech.com and browse through the suspension sections. You'll find 1,000,000,000,000,000,000 on the no name eBay springs and the opinions of those who have bought them.
Your $100 purchase will blow your factory struts, cause the ride to be bouncy/stiff, and will cause the other suspesnion components to wear out extremely fast.
