View Full Version : Apex ARC-8 Hypersilver 17x8.5" review

I moved from an OEM style 135 set up to a square 17x8.5" ARC-8 set up.

Reasons (in order of importance):
1.) Cheaper tires
2.) Performance gains
3.) I wanted to get away from the style 135s before they cracked.

I'll spare this thread the details of my terrible experience buying the two used wheels, but it's necessary to know I bought the wheels in 2 sets of 2 at different times.

COMPANY EXPERIENCE: Iffy, at this point.

My first pair of wheels I bought by actually showing up at Apex's HQ in Livermore, CA to make a purchase. I had been emailing one of their sales reps back and forth for 3 days to ensure that I could show up at their HQ and buy 2 ARC-8s in under 30 minutes. He said yea no problem at all. (I had TWO job interviews that day and squeezed the wheel purchase in between them; for those curious, I scored the job for interview #2!)

I arrived at their location the next day to buy the wheels immediate after the 3 days of communication with the sales rep. The one employee I worked with while I was there (who wasn't a sales person) seemed... "challenged" at best. It was really awkward working with him. I couldn't just buy a wheel from them there; I had to sit in their lobby and call in an order on the phone. No biggie, I guess. It took about 30 minutes because I had to wait on hold. They don't have any sales people located there.

When I finally got ahold of somebody, I was informed they only had 1 wheel in stock. What the hell!? I've been communicating w/ one of their sales reps for 3 days telling them my plans and what I want to do and he couldn't do a stock check to see if they're low on inventory? I guess that's my fault for not directly asking them to check stock, but still. However, they did made it right and shipped the 2nd wheel to me for free, but it took them six weeks to get it in stock. SIX WEEKS!

After my...used wheel experience..., I had to buy 2 more wheels new from Apex directly. This was about 2 weeks before Black Friday, which I know they have specials. I called them on the phone to see if they had released their Black Friday sale information yet, which they had not. That was fine, but the phone sales rep gave me attitude. He said "So why didn't you just buy them online? Why did you call us?" He clearly gave me a tone as if I was bothering him. Who the hell cares?! I'm trying to give you money! He then told me shipping would be about $55, but online said it was $16.99. I told him this and he made the correction manually after asking me to hold.

Overall, I'm less than impressed when working with their company. Their employees are difficult to talk to, at best. At the end of it all, they made things right but only because I had to keep on top of them and ask them to make changes.



PRODUCT EXPERIENCE: Awesome. Awesome. Awesome.

I was able to weigh all 4 of my Style 135s and 2 of my new ARC-8s. Here's the numbers:

Style 135 Fronts (18x8"): 28.2 lbs and 28.0 lbs
Style 135 Rears (18x8.5"): 28.4 lbs and 28.0 lbs
Squared ARC-8s (17x8.5"): 17.4 lbs and 17.0 lbs

Since I only had 2 ARC-8s to go on (I mounted the other 2 before weighing them), I'll average all 4 at 17.2 pounds. That's a rotational weight savings of 21.8 lbs on the front and 22.0 lbs on the rear for a total rotational weight savings of 43.8 lbs. Quite a bit.

Can it be felt? Oh yes. Oooooh yes. I don't have any real numbers, but I was using the butt-dyno. It was immediately noticeable in acceleration at all levels:
- In 5th gear (in an auto), a simple 65-70mph increase to pass a car felt easier and with less effort.
- In 1st gear from 0-60 acceleration was moderately quicker.
- In 1st gear from a 20mph roll up to 3rd gear (70ish?) was QUITE noticeably quicker. It was an improvement that made me smile.
I'm guessing my 20mph roll felt faster because my VANOS is shot and the lack of power down low made the 0-60 feel not too different (I'm hoping to get it replaced at the end of the month w/ a DrVanos).

One other tangible benefit is the ease of care. I can clean these wheels in probably 1/3 of the time the Style 135s took.

Overall, I'm very happy with my purchase of these wheels. They look great (although the Style 135s look better), perform even better than they look, and will save me money on tires (simply because I went from an 18" to a 17").

What tire size are you running now? 245/40/17 would make your car feel even more peppy. :)

Awesome review! I'm torn between these an a set of style 68's right now. The Arc-8's look great on your car.

The 68's are most definitely are cheaper, but I do not think they weigh less. The ARC-8's are also easier to clean and I believe have better clearance for a BBK. I require spacers on my 68's to run my BMW BBK.

Rears are 245/45/17. Fronts are 245/40/17.

Why do you say it'll make the car feel more peppy? Smaller diameter, so smaller "final drive?"

I think I've read style 68s are about 21-22 pounds. Still lighter than the 135s, but not as dramatic difference as the arc-8s.

My dad recently sold his staggered style 68s. I think for $275? That's about 1 ARC-8 lol

Yeah slightly shorter final drive and slightly less rotational inertia.

Why taller in the back? That's different.

Cuz it looks badass!

Actually, the 2 used wheels I bought came with the tires. I didn't realize they would be a whole inch bigger. I've rubbed a few times. When I get new tires I'll get the correct OEM size. I wish this size didn't rub because I think it looks awesome.

According to tire rack, the 245/45 and 245/40 are both 25 pounds (for my tire). So I doubt I'll feel much difference.

My mpg will take a hit though. I've seen about .75 mpg less at highway speeds on these tires, and they're only .3" smaller diameter compared to OEM style 135 with 255/35/18.

A whole inch less of diameter will probably knock that down a lot :(

they're actually 0.7" taller than the stock 255/35/18 rears.

They might be same weight or maybe the shorter tires are slightly lighter but not enough difference to show up in the spec. Even if they are the same weight, the mass is slightly closer to the center so easier to accelerate.

How much less are you spending on tires with these? I want to get the Arc 8's and I am still deciding if I want 18 or 17.

Depends on brand of tire, but my BF Goodrich G Force Sport Comp2 tires are $119 for 245/40/17 vs $170 for 255/35/18. So $51 PER tire. $220 per set of 4 after taxes.

Michelin PSS are $163 vs $225 for the same sizes. So that's $62 PER TIRE. $250 per set after taxes.

That's quite significant to me, especially if I'm going through a set of tires every 18-24 months from autox/daily driving.

PLUS the 17" wheels are cheaper and lighter than the 18" wheels.

That is a big difference. I will definitely look into it now.

Unfortunately Apex informed me that they would rub the suspension with a 255/40R-17, or a wide 245, so spacers would be required.

That doesn't make sense to me. The 17x8.5 has an offset of 40. Is the tolerance really less than 1 mm? Are you lowered?

I just came across this so sorry about the late reply.


Ok thanks, does the 17x8.5 alleviate this issue with clearance? I am probably going to run 245/45-17. --Jay



Jay,

Unfortunately running the 8.5" width does not alleviate the issue if you were to run the same tire sizes, as those tires are the reason that you need a spacer to clear the struts. The tire width is much wider than stock, and rubs onto the struts.

If you have any questions about Apex, just reach out to David. #1, I'm an idiot. #2, it's his product.

I wish this size didn't rub because I think it looks awesome.

Are you lowered or on stock springs? Considering a 245/45/17 square setup.

245/45/17 will rub on stock set up, which is what I have in the rear.

You need 245/40/17, which is what I'll be getting next time.

Last fall I bought some satin-black 17x8.5 ET40 Arc-8's on sale (~$750/set) at Turner to replace my 135's (planning to run 245/40R17 PSS). I was waiting until spring to mount them, but I happened onto a recent group-buy and pulled the trigger on some anthracite 18x8.5 ET38 Arc-8's ($956/set with free shipping) like I had wanted originally (this was only feasible due to the fact I was looking for new wheels for my new 330xi, so I'm going to do some swapping of wheels between cars). So, now I'll be in the interesting position of being able to test the wheels head-to-head on my ZHP.

My big question is: What are people's thoughts on mounting my current, staggered (225/255 PSS) tires on the square Arc-8's? I suppose I'll forego some of the handling benefits of squaring up the tires, but I'd hate to see my current tires go to waste when they're at least 75% new.

Never mind... went ahead and bought a new set of 245/40R18 PSS's. The Michelin discount put me over the edge.

Ya the $750 for the set was a steal and I kinda regret not buying them even though I don't think satin black would look that good on BSM...

I hope the Satin Black wheels look good with BSM, because that's the color of the 330xi they're going on. It'll be a month or two before I get them mounted but, when I do, I'll post some pics.
