I am going to have my ARK Springs and Eibach Sways both front and rear installed in the next couple of weeks on my AWD Stinger. I went to the KIA dealer where I bought my car and they quoted me the following labour times: Springs 4 hours, sways 1.4 hours. A local performance shop similar shop time. These seem like reasonable hours (based on what I have read on the forums here as well as install videos online) - would the people that have had this done agree? If anything, I thought both could take a bit longer. The local performance shop works on Porsches, Mercs, Audi's etc. but not on a Stinger yet. But I have perhaps a bit more confidence in them than the dealer as they don't strike me as the most caring group. Are these install times accurate? Thank you for your time
