Regarding the review of the coilovers and a comparison to XYZ coilover:
If you are in SO. Cal. do yourself and that thousand bucks of yours a favor and show up at one of the events we are attending and ride along to see how these things drift. Anyone who tells you the product they sell is the best is just bullsh*t*ng you. So come see for yourself. If you are an amateur or pro am drifter, these coilovers are going to be great bang for your buck. If you want your daily driver to ride similar to the stock suspension go buy someone elses street spec coilover. These are called MAX competition suspension coilovers for a reason, they are great for drifting. They have pillowball uppers front and rear with spring spacers for uncompromised performance. They have urethane lower mounts instead of rubber. Compaired to most street spec coilovers with 32 way adjustability The MAX coilover softest setting is equal to the other's hardest setting with the same range of adjustment. They are aggressive. Made for drifting, not for pansys. At the same time they do a decent job damping bumps like the insane launch ramp to the infield of the Orange Show Oval. And if you do manage to somehow blow one up, replacement dampers are only $100 and are in stock, no rebuild downtime needed!

This vid is all in car cam of me at Horse thief mile equipped with the MAX coilovers and multilink. I'm no pro evidenced by the sweet course out at the end, but you can see the suspension's ride, predictability and handling pretty well here.
