I believe the correct offset on our cars for a 7" wide wheel is 53mm. of course, the proper offset varies by wheel width. Its very confusing. =)

I can confirm that 5Zigen FN01R-C = 17x8_ET48 does not fit on the 04 sti. I found out the hard way taking it to bj's tire to put them on. First, they frekin stripped some of the paint off the area of the lugnuts from the stock lug size being too big. Then they scratched the front brembos from putting them on when they didn't fit without rubbing.

What do I need now? I figure a spacer...what size and where do I get them from? Also, I need new lugs...can u suggest something? I guess I prefer a lug with the hollow inside so you can tighten and losen from the inside (so they won't scratch up the rim... Also, the center ring of the bbs fits snugly...the 5zigen doesn't have a full center ring (makes sense?). Is there a hub extender I can get?

Thanks.

I concur with philw007, the 5Zigen FN01R-C = 17x8_ET48 DOES NOT FIT on the 04 sti. Kym at Aerosim and the 5zigen web site were correct in saying that this size wheel will not work on the Sti. Iím not sure what magic FASTRPH used in getting the 17x8 to fit, but they do not fit, as ami2fst4u said, without spacers. I ordered the 17x8ís based on the information on this thread. Unfortunately, I did not see philw007ís reply until the day I received my wheels from UPS. Luckily I did a dry fit before getting the tires mounted. I did do a test to see what size spacer I would need in order to make the 17 x 8 clear the Brembos. It looks as if you would need a minimum of a 8mm spacer for it to work. This would also entail using a longer stud because you cannot grab enough thread using the stock studs. A 17x8 wheel with a 48mm offset and a 8mm spacer would put the outside edge of the tire rather close to the inside edge of the fender. I spoke to a rep at 5Zigen and he confirmed the 18 x 8.5 wheels fit on the Sti. I sent the FN01r-C back to the company I ordered them from on Friday. This little experiment cost me $120 in shipping costs. I still havenít decided what wheel to go with. I know one thing is for certain, whatever wheel I decide to go with I will base the fitment information on the manufacturerís recommendation.

I agree, I was talking with Kym and she asked the manufactures and they told that 8mm spacers are required. It is not recommended to use the spacers as the lugs will not get tightned all the way. It sucks not to have many options for STI wheels.

Here's the 5zigen update on the fn01-rc 17x8's.

First, 5zigen was very friendly and helpful. They got some 8mm spacers machined in the proper bolt pattern for the sti. Just got back from putting them on...barely...

If the threads on your lugs are a little messed up, they will strip. I stripped 7 of my nuts using the torque wrench set to 70. I can barely get 5 turns on the nuts (more like 4.5 turns) as the stock bolts are a little short. I feel a little worried...is this ok?

Is there any options to get longer studs? Or am I better off getting new wheels?

Thanks.

From what I know there has to be atleast 6 turns to be safe. I would recommend wait for another 4-5 months and there will be more options for STI.

Impreza WRX STi SSR Professors

The guys at GRUPPE-S.com said the SSR Professors would fit in a 17inch (8.0-8.5, cant remember). Thats a great looking rim that has not been listed.

Id love to know the weight.

I'm confused regarding the fitment of the Prodrive PFF7's. Some people say they fit, but they are not listed here. I guess I'm wondering if the 18 x 8.0 PFF7's will fit an STi. A friend of mine is running Rota SDR's (17 x 7.5) for his race rubber and they fit his STi no problem. Can someone please help me out? I like the look of the PFF7's (since they look a lot like the GC-07's) and although the GC's are what I want, the price of the PFF7's is better.

I too have heard of the PFF7's fitting yet haven't seen any real specs (as far as size, width, offset), with that said I don't want to add them yet until I can find out all the correct info.

TO ALL:
As for the 5Zigen FN01R-C in 17X8, I have now removed them from the wheel fitment list. I am still a little puzzled as to why some people have had problems and others haven't (i.e. FASTRPH). Never the less sorry to all those that bought them and have had fitment issues .

I am pretty sure they are 17X8_ET49, they do make them in 18X8_ET49 as well. I am still awaiting for another vendor to confirm this as well (more so I don't put up any more wheels that have fitment issues). If they do fit they will def. be my choice in wheels (ahhh 3 piece, SBC, and 19lbs. for an 18" ).

PFF7s fit just fine. They only come in 18x8" with a +51 offset (info. can be found here; Prodrive USA). There is plenty of clearance with the Brembos, but you *might* have issues (depending on camber) with the inside lip rubbing against a coilover assembly (encountered this on my old WRX wagon).

Hey Mike, do you have any pics of your car at different angles with the PFF7s on? I'd like to see what they look like from the side and such. If you do, could you please email me?

[b][list]

If you don't see a wheel/offset listed that you KNOW fits the STi please post it, and I will update the list as more wheels come available. I too am still waiting to here back from a few manufactures as to other wheels that fit, and I will update accordingly after I get responses.
I've been e-mailing the folks at Ronal:

http://www.ronalusa.com/wheels.html

and

http://www.ronalusa.com/cars/subaru_impreza.html

They claim their following wheel models fit the STi:

R7, R38, R39, LV, and RT in 17+ inches

They did update their web site to list STi fitaments since I first contacted them last week, so they seem "eager" to play in this space.

I can't vouch for any of this, at least not yet. I'm eyeing the R39's in a 17 X 8 for winter duty, but need to speak with them about the correct offset in this format. I haven't gotten that far along yet.

Anyone out there running Ronal wheels or worked with this outfit? If so, how about some feedback?

I don't have a side shot, as I only tried that one wheel on before I sold the set. There is a picture in this thread on another member's STi;

I'm currently using a set of Rota SDRs with Dunlop WinterSport M2 tires;



When I return to CA in the spring, I'll be purchasing either a set of 18x8" Prodrive GC-010 (British black) or 18x8.5" Volk LE28N (gunmetal/polished lip).

hi!

i just fitted one of my rota battles (had them from the WRX) on the left front wheel and it clears the brembos with a lot more clearance than the stock rims.

drove around - no problems with clearance (but it was weird driving around on 3 contisportcontacts and one azenis )

personally, i like the look of the battles since they show off the brakes really well. only problem is i don't think battles are made anymore, but you might be able to snag a set on private classifieds or ebay.

sorry i'm a bonehead - i forgot to mention the size. they are 17x7.5". i am pretty sure the offset is 48.

i disliked two things about the battles when i had my wrx:
1. the spokes curve outwards from the hub to the wheel, and i didn't like the looks of it. however, for this exact reason, they clear the STi brakes (the stockers' spokes also curve outwards).

2. you can't get an X wrench into the sockets to take the nuts off, because the sockets are not big enough. you've to use a regular extension wrench, and at the track it's annoying as hell when it takes half an hour to change your wheels

PM me if you have questions, since i don't check this forum often.

raj
PS: no i'm not selling them

I want to let everyone know I have verified fitment of the Racing Sparco Tarmac 17x7 +48 on a STi. I just received them yesterday and did a dry fitment to make sure they worked. They give 3 Ė 4mm of clearance on the spokes to the caliper, which is what Brembo recommends as a minimum. They are not hub-centric so they do required hub rings, which came with my order. They also came with center caps, valves, decals and a lug nut socket. I have a set of McGard Spline Drive lug nuts to go with them. Iím not sure if the stock lug nuts will work. Iíll let you know if the stock lug nuts fit on Saturday after I get my 225/45-17 LM22s mounted and I put them on the car. Iíll of course be using these as my winter wheel/tire combo. The design of the Sparcos is a little more complex then I would have liked for winter, but I originally went with the 5Zigen FN01R-C wheel, but they didnít fit. The Sparcos look like they are very well made and sturdy. I weighed them on a digital scale and they are just over 20 lbs (my scale measures in .5 lb increments so they are somewhere between 20 lbs and 20.5 lbs). They arenít light, but that is over 2 lbs lighter than the weights I have seen posted. As long as I had my scale out I decided to weight the stock BBS wheel and tire. They came in at 42 lbs. After I get the LM22s mounted on the Sparcos Iíll weigh them together.

I purchased the Sparcos from www.HopUpRacing.com, which is where I originally purchased the 5Zigens. They have very competitive pricing. If youíre looking for the 5Zigen FN01R-C in 17x7 or 17x8 for an Impreza or WRX, or the 18x8.5 for the Sti, they currently have phenomenal pricing on them. Just check their site. If you have questions call and ask for Steve, heís very helpful and great to deal with.

I had also considered getting the Gram Lights 57S in a 17x8.5 +50. Steve at Hop Up Racing directed me to a rep at Mackin, which is the US distributor of Gram Lights. The rep said a friend of his tried the 57S in 17x8.5 +50 and they didnít clear the Brembos without a spacer. The rep also said that as far as he knew none of the current 17Ē Gram Lights will work on a STi without spacers. Until I get a verified fitment by someone with a STi and a set of 17Ē Gram Lights without spacers, Iíll go with that information.

I don't see any reason 17x7.5" ET 50 SSR Competitions won't fit. I have the Rotora brake kit on my wrx and they have 4 piston callipers with 330mm rotors. There's lots of room left too. If there's anyone in the D.C./Baltimore/Annapolis area who's interested in these wheels and would like to see if these if they fit, just let me know.
