the last one I had was an RK before that an EK 520SRX, the other ones I had gotten the strongest the dealership had but I don't remember the brand. They usually pull themselves apart in one launch or second gear hit. Heres a pic of a streched part, theres quite a few links like that even one broken one. It was oiled up at the time, just been sitting in my garage corner for a while.
