Winter/rain/snow, traction, 370 whp. There is a point when the track is closed down due to weather and there is a reason. You will not get stick-like-glue performance in the wet. If you read the responses to your post you will see the common thread that it appears as though you are trying to defy physics and possibly reality itself. This is not a judgement, just an observation. Assuming that your suspension is already fully sorted out (only because stock
suspension is lacking for stock
HP), and you have an adequate wheel width to support the tires you use in the summer at PIR, SIR, Mission or whichever track you frequent, then you have only to decide which compromises (you can't have your cake and eat it too) you are going to make. If you want to resist the laws of physics this could be painful and expensive. I live in Portland, I travel over the pass in winter, I drive to Seattle in the pouring rain and I got a set of tires for the winter that are a compromise. I got some ohtsu zexius xi 427's in 225-45-17 and did not think I would enjoy them. They handle standing water surprisingly well and they brake nicely for what they are, turn-in is responsive and they are SAFE in the wet. Haven't been in the snow yet but I can tell you that if you find a tire that sticks like glue in the dry and hot, the cold and wet, the snow and ice, never letting you down, try not to be upset when you wake to find you were dreaming.
