Shock absorber opinion
I did a write up on KYBs over on the corner-carvers forum about 15 years ago, AFAIK nothing has changed since then, I do not like them:
'Good' Shock Tech

"As promised.
<RANT> Back when I was much younger (25 or so 
) I bought a set of KYB shocks for my ’66 Mustang thinking they would help my car handle and ride better… Not so much. 
What I got was a car that would shake the fillings out of your teeth and tended to snap sideways when it wasn’t pushing the front end. At one point the driver’s side front KYB actually snapped the upper mounting bolts popping to hood open at about 30 MPH (a quick foot on the brakes saved the hood, but almost got me creamed from behind). This got much worse when I installed stiffer springs. Now, many years later (24 or so 
) I have the benefit of hind (and seat of the pants) sight through many iterations of the setup on the Mustang, My Barracuda, my Dart, and of talking to other people about their experiences with KYBs.
My analysis of what KYB has packaged (foisted?
) as a performance shock is that they’ve dialed in a LOT of compression damping to prop the corners up in hard cornering/transitions and placed the knee (if there even is one) in the compression damping curve quite high to provide a “performance ride”, while at the same time they’ve only provided enough (barely) rebound damping to handle some levels of “stock” springs. The result is a car that feels quick and responsive initially, but tends to skitter and dance its way towards the ditch or guardrail when being driven at even 7/10ths on any surface that isnt glass smooth; forget about trying to balance the car on the limit of the tires at an autocross, the chassis will tend to wind up to certain point, then “sproing” right on past the limit without so much a “how-do-you-do?”. 
I can’t help wondering, based on my own experience, and that of others (mostly MOPAR A, B and E-body guys) I’ve discussed this with, just how many kids have spat themselves off of the road because they expected a shock being sold (and hyped in all the popular rags) as a “performance” shock to actually work like a performance shock?

All IMNSHO, YMMV, BYOB. "
