One of the things about the tubular LCA design is that they're not as tall in profile height as the original LCA's. In fact, at the location of the original bump stop the Qa1 LCA's are about an inch shorter in profile height. That means a full additional inch of travel at that location, which means almost double that amount of travel at the wheel. Meaning, you're a lot less likely to bottom out the tubular LCA's than you are a stock set of LCA's.
