-1 will significantly improve acceleration, but you'll lose about 4-5 mph.

Your speedometer is off 8% or so from the factory, going -1 will make it off 15-15% total.

You can install a Speedohealer to fix it. We have them in stock and we'll calibrate it with a GPS to be spot on.

I just went -1 in the front on my 07 GSXR 600 about a month ago. I love it! You can definately feel the difference on the acceleration ... it's a little more torqee. I havent noticed any losses on my top end, because it is so minimal and at really high speeds that I am hardly ever there.
Yeah, your speedometer will read wrong. Its a percentage, for example ... when I mine read 25 my buddy with a stock GSXR 600 was going 25 ... when mine read 85 my buddy was going 80. so the faster you go the bigger the difference will be.
And yeah, you can still use your stock chain.

go with the front, easy to do yourself, use stock chain, cheaper, make more of a difference than the back will.

Yeah but it sucks on the 05-06 636 as we already have a 14t c/s. :/: Going to a 13 KILLS the chain.

Matt,
I'd go with a -1 first and see how it feels. For most people it's enough, adding =2 on the rear on top of that is pretty overkill.

Only issue going -1 on the front is when you hjave a small sprocket to start with and go down, it can wear the chain faster.

+2 or 3 on the back is about the same change as -1 on front.
