I am thinking about selling the TRD Prius Plus springs on my 2011, and going back to the original stock springs. The handling improvement was simply non-existent (if not a downgrade) with the 15" after some miles were accumulated; I truly think these springs were tuned for the 17" wheels. The springs are still on my car now and have approx 11k on them. I would be interested in selling them for $200 locally and help the new owner with installation, if interested. Otherwise, I am willing to entertain other reasonable offers as well. Thanks. I am located near Monterey, CA but would be happy to meet anywhere in the SF Bay Area.
