JIC is ok too, what is great about them is that they have everything in stock and very quick to get. As for Tein, they are mostly for the civic or small compact vehicle and most people still don't like them that much. We own a shop here and even my reps (all from Japan) from other companies say don't buy tein. Here are the list of good companies, Kei-office, Apex (Not WS), HKS, Cusco.
By the way, my suspension came with 20kg Front & 16kg Rear spring rates due to the very heavy weight of the vehicle. See what Tein offers.
