Okay, so the stock FZJ80 driven gear is 32 teeth. Slee offers a 31 tooth driven gear but that will only make it 3.2% faster. I need about 7% correction. Anybody find a source for a 30 tooth? I already called the dealer and they don't carry it or Toyota doesn't make such a part. I'm trying to find a less costly solution than the Superlift Tru-speed Calibrator. I am exploring the option of getting a custom Ratio Adaptor. The cost is $90 from http://www.speedometershop.com/ratio.html Anybody try this?
