The spring bar diameter on the Carbotech models are enlarged to the size of tubes so you dont need them. With drilled lugs, you still should have been able to remove the strap with tubes. I cant imagine a circumstance changing straps you could ever crack a lug unless it was blatant operators error. To push out tubes from oem straps, you use a small Philips head screwdriver and push the tube directly out of the strap.
