My advise is to not get the speedtech system. There is no reinforcement to the rear sub-frame where the sway bar attaches and as a result, the rear sub-frame can be torn apart when hard cornering is being done. Unless you plan on doing some reinforcement to the needed areas, I would suggest getting the similar Comptech system. It may cost a little more, but the tie bar covers much of the rear sub-frame and strenghtens the sway bar mounting points.
