Maybe they were different OEM tires. As I said earlier, I've used the bridgestone RFT in the past and there ok. The continental RFT were worse.

Pretty sure it isn't going to work well if you have the same continental RFT as I do.

M sport package here in the US has a higher wattage radiator fan and an additional radiator in front of the driver side tire
I have Bridgestone Potenzas on my 335. My 435 had P Zeros.
The M sport has an additional oil cooler; that is not a radiator. I had no idea the fan was different.
