Can anyone tell me if there has been any changes to the brakes or fitment for rims on the 2010 MS3? Looking for winter tires on TireRack and they have a surplus of options for the 07-09 MS3 winter wheel/tire combos, but for 2010, it tells me you have to call.

Aren't they identical? Anyone know?

They are different. The 07-09 uses 18x7 +52.5mm offset with 215/45 tires while the '10 uses 18x7.5 with 225/40 tires (the offset is around +50mm).
 
Just curious, I see a lot of folks talking about switching to different sized rims for the MS3 for snow tires. Doesn't anyone make a good snow tire for the stock MS3 rims? In a perfect world, it would be cool to have two sets of stock MS3 rims, one set with stock "summer tires" mounted, and one set with "snow tires" mounted. Is this possible using the stock Speed rims? Any particular "snow tire" recommended? Thanks.

If you want snow tires go with Blizzaks.

it's usually cheaper or within a couple hundred bucks to buy a complete set of 17 inch wheels and snow tires vs mounting a set of 18 inch snows on the ms3 wheels.
 
The '10 MS3 just came out, and during the summer, to boot. I don't think even Tire Rack knows yet what will fit.
 
2010 speed3 have bigger brakes

Says who?? (dunno)

The spec sheets I've seen show that they're the same sizes:

Front: 12.6" (320 mm)

Rear: 11" (280 mm)

Given that info (and the assumption that the hubs and control arms are the same), I wouldn't think that you'd be required to run any bigger wheels on the 2010 model than on the '07-'09 models. Has there been a caliper change??

I believe the person who stated the wheels are different was wrong. 2010 has same size rotors, same calipers, and wheel specs are the same. Most 16s should fit. Just order a 16 inch from Tire Rack, that way will know it fits.

The wheels themselves on the 2010 MS3 are indeed dimensionally different. I'm not sure if they're still using a +52.5 mm offset, but the dimensions of the 2010 wheels are 18" diameter x 7.5" width, whereas the earlier cars have 18" diameter x 7" width wheels...

The 2010 still has a +52.5mm offset. I was curious about the wheel size so I stuck my phone inside a 2010 wheel at a dealership and snapped a pic of the back of the spoke with the dimension info cast into it. It says "18x71/2J 52.5".

The calipers are probably not literally identical to the 07-09 car, but I very much doubt they've changed enough that you can no longer mount a 16" wheel. Certainly, a 17" wheel should fit. DailyDriver, all that's needed to outift the MS3 for "serious snow action" is a set of 16" wheels with any dedicated snow tire. The only reason people stay away from 18" snow tires is the cost, and possibly the desire for more sidewall. If you want to spend $600-800 for a set of 18's, be my guest.

Also, guys, instead of clammoring all over the forums and getting back answers like "2010 speed3 have bigger brakes" with no substantiating info, feel free to go to some tire shop and test fit a 16" or 17" wheel. That will answer all your questions beyond a shadow of a doubt. Also craigslist works well to pick up used winter set-ups, and you can test fit them before you buy.

I like Blizzaks too, but they're best in deep snow and can wear out quickly on long dry freeway slogs.

Honestly, I wouldn't be surprised if the calipers WERE literally identical...They look that way from the pictures I've seen, anyway...
 
That said, i've got a set of RX8 rims I can get for dirt cheap. Would those fit? I know their 18s, 225/45 tires, and a 50mm offset. Offset itsn't going to make a huge difference, but is it something to be worried about if it's a few mm off? Shouldn't be a problem here, should there?

This is one of the few times that having the "newest" model of something sucks really bad....even online, information is very sketchy until people try stuff out and report back.

Thanks for all the great replies, guys. Everyone here is right...craigslist has been a KILLER place to find snows for REALLY cheap. I mean CRAZY cheap. Someone on there has a set of Blizzaks.... 2 in 225/45/18s and 2 in 265/40/18's for $150. Used ONE season. Your lookin at over $1K worth of snow tires.

Sorry i was wrong, i was looking at the protegespeed specs lol
 
New question for you guys. Looking at some Infinti rims off a 2003 G35 sedan. They are also 5x114.3 bolt pattern. Offset is 45mm. Would these fit our car? I see no reason why not but was looking for your thoughts on it.

Thanks!
