Ford made a proper hot hatch with the MK3 Focus ST & RS. You can be a track hero on the weekends, then enjoy the excellent gas mileage of a turbo four-cylinder for the rest of the week. And guess what? It’s a pretty stylish car too, so you can still flex on insta. GTI owners might have some snide comments, but these cars are generally considered to look pretty damn good… and a nice set of aftermarket wheels make ‘em look even better.

If you want a new look for your Focus ST/RS, a new set of wheels is probably the first place to go, and good news - we specialize in wheel fitment. Conveniently, both models share the same fitment. This guide covers both: Focus ST, 2013-2018, and Focus RS 2016-2018.

Basic fitment info

• Lug pattern: 5x108
• Lug thread: M12 x 1.5
• Center bore: 63.4 mm
• Lug torque: 100 ft lbs

The 5x108mm PCD is one quirk of this platform. This isn’t the most widely supported lug pattern, but it’s what Ferrari uses, so how bad could it be? Based on what we carry in our shop, it’s not too far behind the ubiquitous 5x114.3 pattern, while being about twice as supported as 5x100. In fact, we have just under 100,000 wheel possibilities in 5x108.

The 63.4mm hub center bore is also slightly unusual. A Hubcentric Ring is an easy solution to prevent vibrations. It allows you to step your hub bore up to the size that your favorite wheels come in, probably 66 or 73mm.

Focus RS Brembo brakes

We said that wheel fitment is identical from RS to ST. That’s mostly true. While the arches, lug pattern, and other fitment vitals are the same, the one caveat is the RS’s 4-pot Brembos. The larger calipers on the RS rule out most 17” wheels, which isn’t too much of a shame because most of the time you’ll want 18’s or 19’s anyway.

The main reason to use a 17-inch wheel is for performance reasons. If this applies to you, or you just wanna go against the grain, here are 17’s that are confirmed to fit:

• Braid - Fullrace A
• Team Dynamics - Pro Race
• Vision - 477 Monaco
• Method - MR502

Don’t forget about caliper-to-wheel face clearance - if the wheels you're eyeing come in multiple disk types, consider going for a high-disk (more brake clearance). If you make a mistake, you can save yourself with a spacer instead of needing different wheels - but a bit of research can avoid this dilemma. In our list, we included wheels that are known to clear the RS brakes without spacers. Naturally, this info also applies to ST owners that install an RS Brembo conversion.

Now you know the basics, let’s get into the weeds.

Focus ST/RS daily driver fitment

Fitment Facts
	Front	Rear
Wheels	WOA Forged CE28 18x9+38	WOA Forged CE28 18x9+38
Tires	Continental Extreme Contact Sport 245/40R18	Continental Extreme Contact Sport 245/40R18
Notes	Stock suspension, no rubbing.

This 2016 Focus RS is on stock suspension. The fitment is flush or near-flush with a slight amount of poke in the rear. The ride height makes the front look decent, but the rear is a little 4x4-ish. Besides dealing with the wheel gap, lowering would also give the rear a bit of camber, making it more flush. If you’re looking for a new set of shoes for your daily, a setup like this might be perfect.

This car is on some Alibaba special ‘WOA Forged - CE28’, which look a lot like Volk Racing ZE40 - it’s uncanny. We’re here to give you the specs, not judge your choice of wheel, but we’d recommend the real deal if you’re gonna be tracking your car.

Tires	Continental Purecontact 245/40R18	Continental Purecontact 245/40R18
Notes	H&R lowering springs, no rubbing.

Similar specs to the last, but this RS1 is lowered on H&R springs. These aren’t like cars from the 90’s that absolutely need coils to look decent, a set of lowering springs does a lot for them. The great thing about this, still no modification to the fenders and still no rubbing. These cars don’t have an obnoxiously sized lip on the inner fenders, meaning they normally don’t need to be rolled.

Not surprisingly, these rally-inspired Fifteen52 TurboMacs are popular on this chassis due to the RS’s WRC lineage. These specs are slightly less aggressive than the last, which gives this car perfectly flush fitment *chef’s kiss*.

Tires	Yokohama Advan Apex V601 265/35R18	Yokohama Advan Apex V601 265/35R18
Notes	Lowered on Whiteline springs, no rubbing. Unmodded fenders.

With 265/35 tires, you’ll either have to roll the fenders or deal with a bit of rubbing. The owner of this RS2 reports that it rubs, but only during the most spirited of driving. These specs give a bit of poke, the natural camber you get from lowering isn’t enough for flush fitment. If you wanted to bring this flush there’s always the option of adjustable camber arms. You’ll need about -3° of rear camber.

9.5” wide wheels really accentuate the hips of the ST/RS. Sure, as-is it has a bit of poke, but this is what ‘battle fitment’ looks like. We guarantee this car sees the track, and a 265-wide tire certainly provides more grip than it will ever need.

Notes	Unmodified fenders, no rubbing. Lowered on ISC coilovers.

How about 19-inch on a Focus ST? This set of Forgestar F14s fits the unmodified fenders without issue. This shouldn’t be a surprise as the overall rolling diameter is actually slightly smaller than the 18’s we’ve seen - those thin 235/35 Fitment Facts tires come in clutch.

While the last couple had a bit of poke, this is back to the sweet spot for flush fitment: 8.5” wide +40 offset.

This is the first car we’ve seen on coilovers . Lowering springs do a lot but can’t match the performance of a good set of coils. We got options in our shop from brands like Fortune Auto, BC Racing, Silvers, and a bunch of others.

Notes	BC Racing Extreme low coils. Anderson Composite front fenders. Rolled rear fenders, no rubbing.

So far we’ve looked at fitment that works well for daily drivers that can also be used on the track. Starting with this 2016 ST1 , the last two will be examples of form>function. The ST/RS are good-looking cars so it's not a shocker that people want to give them the stance treatment.

You’ll notice this is significantly more aggressive than the rest - it’s rocking 10” wide wheels. How did the owner pull it off? In the front, he’s using an Anderson Composites fender which gives an extra half inch. In the rear, we can see the fenders needed to be rolled (and possibly slightly pulled). There looks to be more camber than normal in the rear; expect to need adjustable arms if you look to copy this setup.

This is the alternative use case for coilovers. Notice how low the rear is, lowering springs simply can’t do this. Another benefit is stiffer spring rates. The aggressive spring rates help prevent rubbing. Believe it or not, the owner has it dialed in so there’s zero rubbing, scraping is another story.

You can find this car in our Fitment Gallery, a great place to get even more inspiration!

Notes	Air Lift Performance kit. Rolled fenders, no rubbing when aired up.

Air suspension is like a cheat code where you can farm likes on insta while not ripping off any bumpers. Here is what a Focus ST2 looks like with an air suspension kit from Air Lift Performance. Still not as aggressive as the static car we saw prior, but this fitment is beautiful - the wheel lips are in perfect harmony with the fenders.

Again, if you wanna copy this fitment, expect more than just a few bolt-ons. Besides the wheels and air kit you’ll need suspension arms, rolled fenders, and patience. Nailing this type of look takes time.

What doesn’t take time is getting a new set of wheels from us - we have all kinds of designs in stock. We can even combine wheels & tires and ship them to your door, saving a trip to the tire shop (and possibly a lecture on why you shouldn’t stretch tires).

We’re a big fan of these Heritage Hokkaido Directional wheels on this chassis. Whether you want a stance setup, like this one, or anything else, they come in any spec you could ever want.

Wrap up

As with most hot hatches, these cars don’t run massively aggressive wheels. The good news, you can push them pretty far before needing to do special work like rolling fenders. To reiterate: both 18’s and 19’s fit perfectly on this chassis. The sweet spot for flush fitment is 18-19x8.5 +40. If you want to push further, you’ll either have to deal with some poke or get adjustable arms to dial in the alignment (particularly in the rear).
