I'm newish to track days but run in the faster part of the 200 level. I'm still on street tires (q2s) and I know you can just do a couple warm up laps every session, but I feel like that's wasting a lot of my track day. And in the morning sessions the tires just aren't getting as hot. I can get Tire warmers for 160, and a generator for 80 (craigslist). Should I make the plunge so I can rail right from the start of every session or is it not worth it? Anyone else who's been in this situation?
