Yes, I am still on the same 70/60 set up. The pad wear is pretty even between the front and rear. Have a new set of pads and rotors for the front sitting in my office ready when needed. Will just need pads for the rear when ready. I am surprised on how long they have lasted but I may be easier...

I had a similar noise and it was my front strut nuts. They had loosed and every time I hit any bumps I got a popping noise because the strut rod was moving up and down inside the strut mount. Worth a try checking it.

I have a set of Nankang CRS-V2 and they are fantastic so far. I have 3 days on them so far. https://philstireservice.com/product/nankang-cr-s-v2-2023/

If you do not find an issue with your compression, Not sure if you already have but check your O2 sensors. I was getting a missfire that looked like an injector and ended up being my O2 sensors with an incorrect voltage signal. We changed them out and runs perfect now.

You can do what I did, I registered it with Haggarty as a custom car with their insurance and was able to bypass all the emissions tests since the car is now exempt in Arizona and registered as a classic/show car.

I am interested in a set for an S550. Do you have available? Would like either red or black.

Just ordered a pair of rear lower control arms with the monoball's installed.

I have had the Trackspec louvers installed on my car for several years. Not one issue with them and my car has never gotten hot and I live in Phoenix. Sure the Race Louvers may be a little more efficient but the Trackspec work fine for HPDE and do what they are suppose to do. Vent the engine...

I have thought about this a lot over the last few years and I think the ultimate and least expensive way would be to go Gen 3 new short block, Gen 2 heads with 2018 intake. Have a professional build the motor. Paying the extra $3k - $4k for the expertise is well worth the $$$.

I found that I had to reduce the throttle to around 35% and the time was also shorter that what it came with but love it now.

The Xineering blip module plugs directly into the harness without having to cut into the harness. The only taps are for power and ground. It has worked flawlessly.

I spoke to Hankook Motorsports this morning and they did confirm at this time, no more 305/19 RS4's for 2023
