i've been away from stt a minute. due mostly to scheduling been riding w/ x-act, but wanted to say the stg dual temp warmers i got from stg are the shit! 3 track days now and they have been flawless! i highly recommend them!
I bought two sets of them last year.......a set for me and a set for my wife's track bike, and you are right....they are a great product.
They're made for STG by Chicken Hawk Racing, so you're getting a great product. iirc, they're nearly identical to CHR's Suzuka tire warmers, which have been used to great effect by Vesrah Suzuki in the AMA this year.
