Installed ome 880 and 906 springs with bilstein 5100 shocks on my 02 2wd t4r. After installation I noticed a vibration in the gas pedal when I take my foot off the gas pedal. Most of the threads I looked at had vibrations when the gas was being applied. I had a front end allignment done a couple days after which seemed to help a little but it's still noticeable. Any advice?
