I don't think you can....apparently limiters are already "built-in". I would suggest going with OEM E46 M3 RTABs + limiters, polyurethane does not deal with multiaxial deflection as well as rubber and will squeak if you don't put enough grease. For this reason, a couple shops I can think of off the top of my head suggest using OEM + limiter for the street, or solid (aluminum) for the track, but nothing in between.
