I got some 3:73'z and my speedo is off, i am planning on getting some 17's 03' r's, but anyhow, with my gears, and future tires, what driven/ drive speedo gears do i need? im doing a clutch so i figure why not just do it now?
Unless you want to change two gears, one of which is inside the tranny, then get a white 23 tooth drive gear. It will get you within 5%.
The red 26 tooth may be for when you change the driven gear as well, but I don't know. All I know is that I did the 23 tooth one and it's on and I'm happy with it for $15 and 5 minutes. Hope this helps.
When changing the gears to anything past 3:55s like 3:73s or 4:10s you need the 23 tooth , but dont you also have to change the transmission drive gear also to be exact?
