17x9" ET30 with 255/40-17 is actually a direct fit on stock suspension or lowering springs, and would be our recommendation for your wagon. Certain coilover setups will require front spacers however.

The 8.5" ET35 can also be used as a more conservative option, but the 9" ET30 fits so well that there's really no reason go with the 8.5" ET35.

Regarding the face profiles: Because of the variation we don’t have definitive profile numbers at this time, but your assumption is correct. 17x8.5" ET35 would be pretty similar to a profile 2.

Nice thanks Dylan, looks like a 17x9 et30 square is the way I'll be going, it's on stock suspension but might get Koni actives and some m sport springs down the line.

Would I need all new bolts all around? Would you recommend spacers in the rear?

Probably would go with a 255/40-17, I've had good luck with the hankook v12 in that same size before as a decent budget summer tire.

No rear spacers are required, and most owners don't find the need to run any. However, 12mm rear spacers can be used for an aggressively flush fitment on a pre-LCI wagon/sedan, but will likely need rolled fenders to prevent rubbing. 5mm spacers can also be used but may still leave more to be desired.

New bolts aren't required to use our wheels unless you're adding spacers and need extended lengths.

Hi Everyone,

We have just updated the original post with two brand new EC-7R and ARC-8R videos. These videos include new on-car footage for both wheel designs, showcasing the new wheels in various lighting conditions and angles. These videos are definitely worth a watch, especially if you have been craving to see some more content involving the new forged wheel designs.

Enjoy!

We have clearance, Clarence.


Our original flow formed ARC-8 was our first wheel design, and utilizes an older barrel profile that can have compromised brake clearance with certain BBK setups. With the forged ARC-8R, we took everything we learned from the original ARC-8 and applied it to the ground-up development of our all-new profiles and dies. This resulted in a tremendous increase in brake clearance when compared to the flow formed design, with an inner barrel that can clear all the way up to the colossal 380mm Brembo BBK with ease.



To learn more about the obstacles we faced when developing these zero-compromise barrel profiles and dies, along with how we worked to overcome them, please feel free to check out our blog post that dives deep into the topic of forged wheel brake clearances.
https://www.apexraceparts.com/blog/w...ar-big-brakes/

To help showcase some of the new ARC-8R features in action, our friend Kurt (@lsrteg) brought out his incredibly clean and seriously well-equipped E46 M3 for a photoshoot. Sitting on a set of 18x10” ET25 ARC-8R forged wheels finished in Brushed Clear, this E46 M3 had us picking our jaws up off the floor. Just look at how the all-new ARC-8R barrels completely dwarf the massive 355mm Stoptech calipers!

If you would like to read more about Kurt’s E46 M3, please feel free to check out our blog feature on his car, complete with a full build breakdown.

Tires are only as effective as the wheels they are mounted on.


You can buy the stickiest tire on the market, but if the grip level exceeds that of the tire’s bead, you’ll end up with a tire that slips around the wheel. Under hard braking and acceleration, this slippage can cause unwanted wheel rotation within the tire. This rotation can upset the tire’s overall balance, as the wheel weights have shifted from their original position. For those who have to drive home from the track and commute to work the next day, a vibration or wobble through the steering wheel could potentially be felt due to this imbalance. In a situation such as this, the affected wheels and tires would require rebalancing to fix the issue.

At APEX, we are at the track and on the forums, placing ourselves at the center of discussion for topics such as these. While wheel knurling isn’t a new and groundbreaking concept, we saw an opportunity to improve upon it from our previous designs, in a way that best supports the constantly growing demand for more grip. Some wheel manufacturers add knurling simply to include it in their list of “features”. However, it is clear this “feature” can be lacking in performance when the knurled edges are smoothed over by a layer of slick glossy paint, effectively reducing the functionality of the knurling.

For our new ARC-8R and EC-7R wheels, we wanted to focus on reducing unwanted tire slippage as much as we could. The knurling pattern on these new forged wheels is specifically designed to maintain the highest amount of grip we could achieve with the bead of the tire. On top of that, we ensured that the knurled edge of the wheel is completely protected during the painting process. This leaves us with a sharp and deep toothed knurling, that isn’t compromised by the manufacturing process in any way whatsoever.

Our friend Chris (@chrisreardon91) dropped by the shop with his purpose-built E46 M3 track car to get a taste of what the forged EC-7R has to offer. With a 18x10” ET25 square setup wrapped in 275/35-18 Toyo Proxes R888R tires, these Brushed Clear EC-7R wheels not only look the part, but they also provide some serious functionality out on the track as well.

Finished in Satin Black, these 18” ARC-8R forged wheels compliment this Sakhir Orange F82 M4 with a tasteful, yet menacing aesthetic. While our original flow formed 18” ARC-8 wheels lack the barrel clearance necessary to clear the standard brakes on the F8X M3/4, our forged 18” ARC-8R wheels have a new and improved barrel profile, allowing them to clear all the way up to the 380mm Brembo BBK with ease.

From the classic and boxy E36, to the modern and aggressive F80. The EC-7R can compliment just about any generation of M3.

Damn, I need 2 new rims (cracked the other 2) but your flow formed EC-7s over my price range. Crap, back to looking.

Do you mean 255/35? 255/40 is one profile size up and 255/35 barely fits in the front.

Yup 40. Been thinking about going up. The only thing that's keeping me from pulling the trigger is the washer fluid tank. If I remove the liner then the tank is exposed.

I think you'd rub too much on full lock. If you were lowered it would be even worse

Just found out I have three bent wheels and I'm seriously considering a set of 18x8.5" ET35 Race Silver APEX EC-7 Wheels for a square setup on my daily 2008 E92. I see these are already on sale in your website, but are you by chance going to run a Veteran's Day/Military discount in the next few days? TIA!

As others have mentioned, 255/40-18 is too tall and will rub on the front. You can certainly start removing parts until it stops rubbing, but if you're looking to improve ride quality with 255 tires I'd recommend switching to our 17x9" ET30 wheels and running 255/40-17.

Thanks for the post! 18x8.5" ET35 is the perfect bolt-on fitment for your E92. This wheel is indeed discounted on our website as part of a sale we have running until December 2nd. It is not likely to see any further discounts.

Are all wheels currently on sale being discontinued?
I sent a private message about needing wheels for my current broken and discontinued Apex wheels.

Is the current SM-10 in the 19x9 ET30 being discontinued also?
I don't what to buy a new set of wheels only to be in the same situation I'm in now. I can't replace the current broken/damaged wheel I have now (EC7 19x9.5 ET33) so I'm in the unfortunate position of buying a whole set of wheels.

It would be nice if you guys posted what was being discontinued, so people would have an opportunity for a pastime buy on a spare wheel.
I would have gladly bought a spare not to be in the situation I'm in now. $380 vs $1400.

Thanks for the post! It was great speaking with you on the phone today, and I'm glad we were able to find a resolution to your situation.

The sale does not indicate any intent to discontinue these sizes, we simply offer sales throughout the year to give the community an opportunity to purchase wheels at a discount without waiting for a Group Buy.

How about fitment on a LCI e90 lowered on ohlins R&T ?
Would the 17x9 et30 square be the best or I would need spacers up front?

Thanks for the question!

17x9 ET30 should work well on your car with 245/40-17 tires, but you will likely need a 5mm spacer up front to help this setup clear your Ohlins.

I saw that you sent us a PM earlier asking for a quote. I attempted to reply but your PM box was full so I couldn't.
If you'd prefer email, you can email us at support@apexraceparts.com with Attention Tom in the subject and I can send the quote over to you that way.

Let me know what you'd like to do!
