I always see this ITR springs, retainers and stuff for sale is this like the stock skunk 2 versions of stuff. Like is it one the same par as sk2? Or do people use ITR for racing because of stock parts only? In general i see so much ITR stuff.

ITR is usually the best OEM stuff you can get.
Higher spec aftermarket parts will usually top that.
