Jack, thanks for investing time to respond to my starter relay question. My new-to-me S4 is going in for comprehensive mechanical overhaul and I will add this to the list of projects. Again, thank you. Jim
I too have an S4. I installed the squadra chip a few years ago and have been very happy. Have you started the brakes? I planned to change mine this year. Centerline slotted rotors and stainless hoses. Waiting as they are out of stock. I'm interested if you installed the wilwoods and your impressions.
