To answer the original question:

x% = (430-391)/430*100

x% = 39/430*100

x% = 0.090697674 * 100

x% = 9.1%

So, your speedometer (and, for that matter, your odometer) will be off by 9.1%. Of course, this is dependent on tire size vs stock size as well.

You have to get the whole internal assembly. Really not worth it unless you get a kazz or something.
