I prefer to leave thinks oem and in stock form. These are for the most part luxury vehicles, not race or high performance cars, or muscle cars. I'm 55 and went and worked at dealerships immediately after high school in 83. Imo, you start deleting parts that obviously have a purpose being on the car, you generally have problems. That's just common sense, to me. It IS your car so do what you want. Then when you have an issue, you'll be right back here asking for help. Good luck tho.
