here are the numbers:
PCD (pitch circle diameter or bolt pattern): 5 x 100 (this was changed to 5 x 114.3 for the '05 STI, just to make things more complicated)
offset: the typical range is from ET45 to ET55(stock) with ET48 being about average
centerbore - hub diameter: 56.1mm - wheels that have this measurement are known as "hubcentric"

is your '04 a wagon or a sedan?

wagons have less space in the rear fenderwells so wheel width and offset can be an issue - sedans have a lot more room

read the sticky's at the top of this forum, like this one:

http://forums.nasioc.com/forums/show...hreadid=524624

it has a good definition of offset among other things

the stock WRX wheels are 16x6.5 ET55 and weigh 16.5 lbs

most of us end up with 17x7 or 17x7.5 wheels - the 17x7 size is what the rest of the world gets standard on their WRX - we're "special"

other options are 16x7, 16x8, 17x8, 18x7.5 and 18x8. All of these will fit the sedan without rubbing assuming that you also get appropriate sized tires - with some of these choices on the wagon you may need some guidance or you will have to "roll the fenders" to make things fit

if you get your wheels from [email protected] Rack he will make sure you end up with something that fits - Tire Rack has a very large assortment of Subaru specific wheels - ASA and Kazera are popular - as well as the best technical information on the Internet. Read their website and become enlightened. Make sure to go through Luke - the other people at Tire Rack may be ignorant of Subaru's

other vendors who know their stuff are Dave @ Oakos, Brad @ TB Racing and Suby_Dude - all of whom sell the very popular Rota line of wheels

Enkei also makes some good, not too expensive wheels for the Subaru and Nino @ Nino's Auto Accessories and Rich @ Daddy's sell them

There are lots more wheels - OZ, Prodrive, SSR, BBS, Volk, etc. - and vendors, of course - this is just to get you started

if you have already seen a wheel that you like, make sure that it meets the criteria above for bolt pattern and offset - the centerbore can be adjusted for with "centering rings". Many good vendors will specify "Subaru fitment" to make it easy for you

sorry - lots more than you wanted to know, I'm sure. some nights I just can't stop writing...

Don't apologize, the more the merrier. I'm asking b/c I 'm trying to get cheap off Ebay and they of course aren't WRX specific.

I have a sedan.

Would a Universal bolt pattern work? They are ugly but I assume should work. Also, I thought I understood bolt pattern until you posted that 5x114.3 thing for the STI. 5 is the # of spokes right? What is that x100? Would the WRX sedan work with something like 5x114.3?

So what is the highest and lowest offset my sedan car run? What does the + mean? Example: +45 offset.

How cheap is cheap, because you can get the perfect spec. Rotas for $600ish new.

PS Go Lehigh!

PPS use the search function it's all been covered. Or at least read the FAQ at the top.

5 is the number of lugs and 114.3 is the diameter. Your car is 5x100, so 5 lugs with a 100 mm diameter. So to answer you question, the WRX will only work with rims that have 5x100 bolt patterns.

For bolt patterns, read this: http://www.tirerack.com/wheels/tech/boltpatt.htm

For offsets, read this: http://www.tirerack.com/wheels/tech/offset.htm

Also, read the Offset Sticky. It will tell you general guidelines about offsets for different rim widths.

yes the 04s will fit 02/03 wrx.

BUT

the 05 sti wheels will NOT fit the 02/03 wrx's. the 05 sti has 5 x 114.3 bolt pattern, while the 02/03's have a 5 x 100 bolt pattern.

"How could I tell if a rim will fit the WRX? "



Take the wheel in question. Cover it in newly sheared lambswool from the firstborn calf of your oldest ewe. Wait until the first sign of the new moon when the Warrior crosses the Equinox. Burn the lambswool with freshly cut cedar boughs. If the wheel is discolored, it will fit. If it is not discolored, you shall shatter it with a thousand stones and scatter it in your fields.















Or just ask the Wheel and Tire forum
