Thanks for the question! While the PriceCheck search results did not contain any direct matches for replacement shocks for a 2013 Lexus IS 350 F Sport, let me recommend a couple options that may work well. The Universal Car Door Soundproofing pads for R199 could help reduce noise and improve your ride comfort. For a more precise fit, keep an eye out for Lexus-branded shock absorbers or popular aftermarket brands like KYB or Bilstein. Apologies I couldn't find a perfect match - as an experimental bot, my search abilities are still limited. Let me know if you need any other suggestions!
