just by looking at the pictures, it looks as though this company is doing the same thing as KSport and D2, but with less-adjustable shocks and not quite as wide of a range of custom spring rates. Also, the design is virtually identical to the other two, but it's red instead of orange (KSport) or purple (D2).

That being said, I LOVE my KSports, and these really can't be bad at all for the price. MUCH better for the money than Tein Basic or SS.
