Sorry to revive an older thread but didn't make sense to start a new one. Going to read this thread from the start to see if I can find the answer but someone could probably answer before I find it. Looking at getting a used 17.5t Spec R for my 2wd buggy. Where should I start gearing wise? Reading up on these it seems likely just popping on a gear ratio typical for 17.5t might not work. Any tips?
