I know technically the car will accelerate more slowly (assuming they're heavier than stock), but is it even noticeable? I'd like to go to 17" ASA AR1's, but I'm trying to justify the the extra cost (+$230) and weight (+12.4lbs total w/tires) over the 16" AR1's. Especially since i'm gonna be putting on E46 325i brakes soon, which will add even more weight. What do you guys/gals think? | | | 06-06-2005, 04:50 AM | #2 | islander on the mainland Join Date: Jun 2003 Location: SF Bay Area Posts: 286 | Are you set on the ASA AR1s? You might want to consider BBS, because you can get a set of 17" BBS that only weigh 17 pounds. Granted they're more expensive, but the quality is better and the wheels are lighter. __________________ moku 1996 318ti Cali Top w/ Downing/Atlanta Supercharger 2003 M3 w/ CSL trunk, splitters, & diffuser | | | 06-06-2005, 05:11 AM | #3 | Senior Member Join Date: Nov 2004 Location: Minneapolis Posts: 1,587 | Yeah, i'd ideally like some 17's that are lighter than stock (like BBS'), but it's down to a money issue. I know the 17" Kosei K1's are very light and cheap ($199) but I really don't like the looks, so they're not an option | | | 06-06-2005, 06:07 AM | #4 | Senior Member Join Date: Mar 2005 Location: Portland Or Posts: 2,666 | Acceleration is affected by outside TIRE diameter not wheel diameter. So you can get 15,16,17 wheels with tires that are the same overall height and width meaning no significant change in acceleration. Not that the lower sidewall hight won't affect handling but it should not really change your 0 to 60 by much....

Rereading my original post, I realize I wrote that quite poorly I should ask, for those that went to a significantly heavier wheel (regardless of size), do you even notice an acceleration hit? | | | 06-06-2005, 12:10 PM | #6 | Senior Member Join Date: Jul 2004 Location: Delafield, WI Posts: 471 | I've got 235/40 17's on '95 BMW Motorsport Double Spokes. I weighed the wheels on a bathroom scale after they were powdercoated, they're 19lbs. These are lighter than my original 10 spoke 15's. No difference at all in acceleration. | | | 06-27-2005, 11:07 PM | #7 | Senior Member Join Date: Feb 2005 Location: Essex UK Posts: 164 | Go for the 17"'s.........they look so much better and you'll feel more difference from polishing the car and laminar airflow effect than wieght of OEM wheels! LOL 225/45-17 Michelin Pilot Sport on OEM wheels......magic.

You could have 18's on your car and say it does 0-60 in 4.5 sec with smaller rims like say 16's it will probally take off 1/2-3/4 of a second. __________________ 98 Avus Blue 318 ti Active clear outs all around,stealth turning signals,blue led interior lights, 35% tinted windows,K&N air filter, 12" Kenwood Sub, MTX Thunder Amp,Alpine cd changer, Leatherz Armrest,ACS Pedals/Handbrake/FloorMats & Vitesse Tuning Carbon Fiber B-Pillars/CF Spark Plug Cover, New 16" MSW Typer 14 Rims on Goodyear Triple Treds www.myspace.com/avusblueti | | | 06-27-2005, 11:39 PM | #9 | islander on the mainland Join Date: Jun 2003 Location: SF Bay Area Posts: 286 | Quote: Originally Posted by Tyler The bigger the wheel the slower the car.

Usually weight is the issue, since bigger wheels generally weigh more. __________________ moku 1996 318ti Cali Top w/ Downing/Atlanta Supercharger 2003 M3 w/ CSL trunk, splitters, & diffuser | | | 06-28-2005, 12:16 AM | #10 | TRETEN IRGENDEINES ESELS Join Date: Aug 2004 Location: Rhode Island Posts: 3,687 | Quote: Originally Posted by moku If you plus-size correctly, this shouldn't be an issue.

One has 15's the other has 17's i will guarantee the ti with 15's will be faster in 0-60. We are not talking alot here just 10th's of a second. I would pink slip my car on that. __________________ 98 Avus Blue 318 ti Active clear outs all around,stealth turning signals,blue led interior lights, 35% tinted windows,K&N air filter, 12" Kenwood Sub, MTX Thunder Amp,Alpine cd changer, Leatherz Armrest,ACS Pedals/Handbrake/FloorMats & Vitesse Tuning Carbon Fiber B-Pillars/CF Spark Plug Cover, New 16" MSW Typer 14 Rims on Goodyear Triple Treds www.myspace.com/avusblueti | | | 06-28-2005, 06:59 AM | #11 | Senior Member Join Date: Oct 2003 Location: Wilmington, NC Posts: 641 | dude, they are 17's, there is nothing to be afraid of. -chris __________________ 18'' Ace Wheels Pirelli P7000 SS Tires Bosal Brospeed Exhaust B&M Short Throw Kit H&R Sport Springs Euro Clears cat delete Rogue Engineering Clutch Stop Modded Airbox blacked out kidney grilles Suede Headliner/A Pillars S52 CONVERSION UNDERWAY | | | 06-28-2005, 07:50 AM | #12 | Member Join Date: Feb 2004 Location: Vallejo, CA Posts: 47 | "Lets say we have 2 ti's both bone stock both auto.

Well...guess that works for the 1/4 mile but on the track you get that back in maybe two corners with the tire width available for the 17" and if you multiply that by the corners you come out ahead with the 17" especially when to take into account the tire choices available.

I changed from 15" Steels to 15" alloys then to 17" alloys....all OEM BMW wheels and michelin or Conti tyres, and yes I wieghed the assemblies out of curiosity......the 17" are lighter than both other types! Same rolling circumfrence, lighter wieght.........faster car! Best regards David ah yes.......wheres that pink slip gone?

The way I see it, the moment of torque is about the center of the wheel, unlike a motorcycle that has a sprocket. The center will have a harder time mover a wheel that has a larger diameter, just as a larger sprocket has more torque on a motorcycle wheel. It's the same issue when talking about differentials. Now the wider tire will add more friction, that will require more torque to spin the wheels. Quote: Originally Posted by Tyler Lets say we have 2 ti's both bone stock both auto.
