I was looking at your older post "Face-ff: p21S 100% vs Z2 Pro" and was very impressed. I'm currently looking into getting new LSP's and my original combo was to go Z2 Pro and top with P21S 100%. Have you had a chance to do that combo yet? If so was there a thread or could you provide feedback? I have both Black, White, and Silver cars. Hope to hear from you, Thanks!
