I don't think you'd need a new bumper, unless you wanted to revert to a pre-installation state at some later date. By the look of it they cut holes in the existing bumper and plug them with the items marked 6 in the diagram, but likely the bumper would have to come off during the process to fit the mountings marked 3. So with dealer labour rates of c.£100 per hour you're probably looking at a few quid, although in the context of the whole car not that much.lankyandy said:cheers for all the info ther. thats not to badfor the rack, i guess it all comea down to if i need new bumper aswel!
