I was just wondering if it has a full size spare tire. It should because the front and back have limited slip differentials. It screws things up if the tires are not the same height. Well I was just wondering while I wait. Hopefully pretty soon I can just open my trunk and see for myself...

i've had a couple front wheel drive cars with LSDs and they had donuts also. is there something special about both the front and back have LSDs??

Better be a 'nut. If they are that concerned with weight, we'd be lucky to get a spare at all!

This shouldn't be a huge issue with the differentials. If the donut is in fact a smaller diameter than the stock rolling diameter, the differentials will just see the difference as if you were going around a turn and the wheel speeds were different.

Of course you should still take it easy and get that thing off ASAP. It's just a crutch.

I've been pretty lucky in the 11 years I've been driving, and only ever had two flats. So I don't have the best knowledge of spares, but doesn't any wheel (including a spare) have to be at least large enough to clear the brakes? With the size of the Brembos on the STi, I'd think you would have to have a 17" spare.

There is another alternative. Corvettes don't even have a spare, coming stock with run-flats instead.

I saw, in one of those pdf's, that the STi is coming with 24x7 roadside assistance. Is it possible that this could be a substitute for a spare?

If you get a flat in the front you'll have to move the rear tire forward and use the spare in the rear.
If you check out the rallliespec site that was mentioned in some other threads they seem to be selling donuts for the STi.

The quote from the bottom of the page says...

Factory spare wheels used on the STi models with large 4-pot/2-pot brakes. If you have a big brake kit installed and are worried about what to do if you get a flat, these wheels are your answer.

So maybe no worries?

The "M Mobility" kit is standard on the E46 M3 and I think on the M roadsters/coupes as well. Comes with an electric air compressor and a can of goo.

I caught a nail on a cross-country trip somewhere between Albuquerque and Nowhere... geez, I love my full-size spare!

That sure won't help much without a compressor to reinflate the tire once the sucker is (maybe) sealed.

I've been driving a '94 Integra for the past 9 years, and after 100k miles of carting around a spare I never used it once!! Instead I'm going with a small lighweight air compressor and a can of tire sealant. Given that AND a cell phone, I'm pretty comfortable with the statistics in my favor... :eek:
