Speaking for myself, there were a few reasons...
- The Falken is a relatively new tire design vs. the PS2 which has been around for a while. The Falken appears to be designed closer to a track tread pattern than the PS2 also.
- Cost. The Falkens are a good bit less expensive
- People that are capable of pushing these tires much harder than I can seem to like them
- Having had a set of PS2's on a car before (C6 Vette), after about 1/2 of the life of the tires, they were hard and had little to no traction.
This will be my first try with Falkens. If I don't like them, I'll look for something else. I'm more likely to go towards a set of Toyo R888's than the PS2 though for my driving plans...
