Bro, that old agade is very much alive today as it was yesterday. You do get what you pay for. That's part of the reason I have twice as much more money in my Chevelle as I should, because I took cheaper routes the first time only to have and go and redo it a second time. Now, as far as the TCI stuff winning the autocross, it would have to depend on more variables than the product itself, such as skill of the driver, etc. But the part alone may be inferior to DSE or ART Morrison.
Just my opinion since you asked.
