Piero -- in case SP didn't answer your question -- you need to check which perch your coilovers are using in front. Most coilovers use a non-factory perch, usually about 2.25" or 2.5" inner diameter. But some like PSS use the factory upper perch.
You can tell by looking under your front wheel well and see how big the spring is. The inner diameter of the factory-style spring (or PSS spring) is much higher than a 2.25" or 2.5" ID spring. Compare yours to stock cars if you're unsure.
