how slow will i go?

with 17 inch rims, how bad will my performance decrease? will it just mess with acceleration and 1320 times or will it affect top end also? or both?

at the most, you might lose .2 seconds in the 1/4. nothing to get worried about

depends on the weight I'd say, there are 17" which are lighter than some 15" so that would make you faster, if you get heavy chromies or something it will definitely slow you down.

A 17" wheel would have to be considerably lighter than a 15" wheel to allow you to go faster. The acutal weight of a 17" wheel is only one factor that can affect speed - the other is the fact that the rim (the largest concentration of mass on any wheel) is situated 2" further away from the axis of rotation, meaning more force is required to rotate it, even if it weighs the same as the 15".

The fact is is that almost all 17" wheels will be the same weight or heavier than a typical 15" wheel. As an example, the stock 15" alloy wheels on the '99-'00 Civic Si weigh 16lbs (I weighed them myself).

Kosei K1 Racing wheels weigh 16 to 16.5lbs in the 17" size. SSR Integrals weigh 16-17.5, SSR GT1s 16.5-18.5, and BBS RKs weigh 16.8-19.2lbs. A very light wheel, the SSR Competition, still weighs 12.9 to 16.7lbs each (depending on what width you get). These are all considered lightweight wheels - typical 17" wheels weigh closer to 18-20lbs.

Bottom line is you will feel it when you go from 15" to 17". Exactly how much depends, and it won't knock like a full second off your 0-60, but you'll feel it in the butt-o-mometer...

well right now i have the stock honda 14" hubs with caps. i bought 17" tenzo-r av-7's whats the URL to that site with all the wheelk weights and everything. they feel light but the box they came in had 2 rims per package. and there were 2 packages with 4 boxed rims. on the ups slip it said box 1 or 2 and 2 of 2 and it also said 50lbs. so im guessing it could be 25lbs per rim. or 12.5lbs per rim. i want to weigh them but they're still at my shop.

CornerCarver you're right didn't think of that, I was at work when I posted that, I can't think right there :D

Your stock rims weigh 18lbs and your Tenzo's weigh 20lbs, so not too big a difference.
I got this info from

Thats a cool webpage, bracer! My car club has a similar one, but it does not have nearly as many entries. I'll have to bookmark that one... ;)

thats the site i was looking for.
