Personally I would steer clear of them, I've heard alot of complaints about the bushings. You get what you pay for and if it were me I would try Function7, Skunk2 or even Tegiwa Billet ones as they use Energy suspension bushes which can be replaced easily if needed be which is the same story for the F7's and sk2 sell bushes separately as far as i know.
Remember if your changing LCA's, Don't tighten up the bolts when the car is off the ground. Fully tighten when the car is firmly on the ground as this keeps the stress off the bushings.
