First one, no idea.
Second one, why do you not have the AC turned on? I leave mine on all the time and have done for 15 years or more.
As for the tyres, the PS4 tyres I fitted are so much better than the Bridgestone so I can only think how much better the PS4S tyres would be.
I use the AC if the car is steaming up but otherwise switch it off. Not sure if that would make any difference? I might give it a go though, nothing to loose. Thanks
I can't imagine much difference between the PS4 and the PS4S but I reckon they are essential if you want to get the best from these cars, well worth the money particularly as so far I haven't actually spent any
Not today but yesterday I ordered a set of badge skins and my wife is buying me a revo map for Christmas.
You have your wife very well trained, I asked for a VWR turbo elbow but I'm fairly sure the look I got wasn't very positive
