Gentlemen, picking up the X5 Prospec after two years on no racing.

I noticed that the part numbers for the front and rear lower suspension arms have a "B" added to the part number for the new car. What's the differences in the arms?

Thanks.

The part numbers with the B at the end are from the newer MBX5R kit. They are backwards compatible with teh old MBX5 and ProSpec MBX5. The difference is tha the arms were modified where the shock mounts to allow for the additional travel of the longer MBX5T shocks that are on the 5R.
