I have a 2002 f4i and i was wanting to know if anyone knew the stock numbers on the sprokets? Is the front a 15, 16, etc. and what about the rear 44, 46, etc. Id appreciate the help, owner before me said he went -1 and +2!!! Thanks

Do a search theres a few threads on this...I cant remember off the top of my head

stock is 16/46

thanks lim....!

Just in casae you are still a little confused, that means the front is now a 15 and the back is a 48. That is if the -1 +2 is correct.

right, 16/46 are the stock configurations.

Now, my question is what affects as we trying to achieve by dropping or adding a tooth or two?

I can only guess that the front is how fast you go through a specific gear while the rear is for overall mph per gear... is that correct?


I know, i know... noob... but we all gotta learn somehow right?! :)

obzidian- not sure about the front changing the gear and the rear changing the mph, but i know changing either of them will have an affect on both depending on how much of a change.... i have a -2, +2 swap on my 01 and it is great for acceleration and the canyons, but sux on the freeway, turning something like 9k-10k at about 80mph

Dropping a tooth in the front is almost like adding 3 to the rear. By dropping one in the front, you can get away from adding a much larger rear sprocket, and thus keep from adding more roating mass. changes to the front and rear sprocket do the same thing, which is change the overall gear ratio.

How's that -1,+9 do on the freeway and overall? helps u bring the front end up nicely huh? i have thought of putting the bigger rear sprocket but i do canyons alot 2, have u tried tohit the curves with that set-up?
