Seems like your opinion is based on the fact that Denny is a member here. My about his stuff is engineering based. Bolt on shock towers? It’s what carry’s the weight of the car!
I don’t want to bash Denny’s product. If his stuff was cheaper I would be inclined to use it and weld those things in. The price on all these coilover systems only varies by a hundred to couple hundred bucks. Reilly was the first and they have all gone after his price point. It’s only a matter of what flavor you like. Price is the same essentially.
