CMST CT201 Forged Wheels on a Widebody Mustang
This silver S550 Ford Mustang pairs the CMST dry-carbon and FRP widebody kit with 20-inch CMST CT201 2-piece forged wheels in a gold-face, blue-lip finish. The wheels are forged from 6061 aluminium, run a staggered fit under flared arches, and sit over red Brembo brakes. The same package fits both the 2.3 EcoBoost and the 5.0 V8 GT, so the look carries across the S550 (2015-2017) range regardless of engine.

This build is a detail appreciation rather than a how-to. The wheels lead, but the carbon aero around them is part of the same story: a coordinated CMST programme where the arch flares, the offset and the tyre were all chosen to work together. AME stocks the wheels and the panels in this build through the CMST forged wheels for Ford range and the wider CMST catalogue. The sections below walk through the full parts list, then focus on the CT201 wheels, their finish and how they sit under the widebody.
The build at a glance
The starting point is a standard S550 Mustang. Onto it goes the complete CMST widebody kit, which splits into two material groups. The visible show panels (front lip, rear lip, side skirts, bonnet and rear wing) are dry carbon, left bare under clearcoat so the weave reads as the finish. The structural arch and fender pieces that build out the body width are FRP, supplied primed for colour-matched paint, which is why this car's flares are sprayed silver to match the shell while the bonnet stays carbon. Behind all of it sit the 20-inch CT201 forged wheels and Brembo brakes. The result is a wider track, deeper arches and a stance the factory car cannot reach on its standard guards and wheels.

The CT201 forged wheels in focus
The CT201 is the centrepiece of this build. It is a 20-inch, 2-piece forged wheel with a multi-spoke face, and on this car it runs a gold face against a blue lip studded with exposed lip bolts. The combination of forged construction, 2-piece assembly and a custom finish is what separates a wheel like this from an off-the-shelf cast item. Both wheel sizes here sit within AME's CMST forged wheels for Ford range.
2-piece forged 6061-T6 construction
Forging is the core of how the CT201 is made. The wheel starts as a solid billet of 6061-T6 aluminium that is pressed under high force, which aligns the metal's grain along the shape of the wheel rather than leaving the random structure of a casting. That aligned grain gives a forged wheel a higher strength-to-weight ratio, so the part can be cut thinner and lighter while holding the same load. The face is then CNC-machined to its final spoke profile. Because the CT201 is a 2-piece design, the forged centre and the spun outer barrel are made separately and bolted together, which is what makes the exposed lip hardware on this wheel functional rather than decorative.
Custom gold-face, blue-lip finish
The finish on this car is a two-tone job: a brushed gold multi-spoke face, a deep blue outer lip and blue lip bolts, with a CMST centre cap. Because the wheel is 2-piece, the outer lip is a separate component that can be refinished or repaired on its own without touching the centre, so kerb damage to the lip does not mean replacing the whole wheel. Forged 2-piece wheels also open up custom colour choices across the face, lip and hardware, which is how this build arrives at gold-on-blue rather than a single plain colour. The finish is chosen per order, so the same CT201 can be specified in a more restrained colourway just as easily.
Sizing & staggered fitment for the widebody
The CT201 runs here as a staggered set, with a wider wheel and tyre at the rear than the front. That suits a rear-drive car like the Mustang, where the back axle puts the power down and benefits from a larger contact patch. The 20-inch diameter does two jobs. It clears the Brembo brakes sitting inside the barrel, and it fills the deeper widebody arches so the wheel sits flush with the flared guards instead of looking lost inside them. Because the wheel is forged and 2-piece, its width and offset can be specified to match the extra width the arch flares add, which is the only way to get the face sitting correctly out at the guard line through the full range of suspension and steering movement.
1-piece vs 2-piece forged
Both 1-piece and 2-piece forged wheels are stronger and lighter than cast wheels for their size. The difference between them is construction, adjustability and repairability.
| Feature | 1-piece forged | 2-piece forged (CT201) |
|---|---|---|
| Construction | Face and barrel forged as one part | Forged centre bolted to a separate outer barrel/lip |
| Width & offset | Fixed by the mould; fewer custom widths | Adjustable — built to a chosen width and offset |
| Lip / hardware | No exposed lip hardware | Exposed lip bolts; visible deep-lip look |
| Repairability | Lip damage affects the whole wheel | Outer lip can be refinished or replaced on its own |
| Best suited to | A clean single-piece look, lightest weight | Custom fitment and finish, widebody builds |
For a widebody car that needs a specific width and offset to fill the arches, the 2-piece CT201 is the natural fit, which is why this build runs it.
The carbon aero around the wheels
The wheels lead this build, but they sit inside a full carbon and FRP aero package. The carbon panels carry a 2x2 twill weave under a UV-sensitive clearcoat, while the FRP arches and fenders ship primed for paint. Here is how the main pieces work.
The carbon front lip extends the nose forward and down, tidying the air at the front axle and giving the front bumper a deeper, more aggressive edge. It is one of the dry-carbon show pieces, left bare so the weave is the finish. AME lists the matching part in the CMST front lip for Ford range.
The raised carbon rear wing, the "high wing B" on the parts list, is the most visible piece from behind and adds rear presence to match the widened body. It is available as the CMST rear wing for Ford. The carbon bonnet, the "A" panel, is the other large show piece and the reason this silver car keeps a bare-carbon nose; the equivalent part sits in the CMST carbon bonnet for Ford range.
At the tail, the carbon rear lip frames a dual single-exit exhaust layout and closes off the lower bumper. The side skirts, also carbon, are shaped specifically to meet the arch flares so the body reads as one continuous widened line down each side. The full set is part of the CMST carbon fibre body kit programme.
Fitment and finish
A widebody build only works if the arch, the wheel and the tyre are matched. The FRP arch flares add width to the body, and the CT201's width and offset have to be specified so the tyre clears the new arch line through full suspension travel and across the steering lock at the front — too much poke or too little clearance shows up as rubbing on bumps or on full lock. That careful matching is the whole point of running a 2-piece forged wheel on a car like this.
Finish work falls into two streams. The FRP arches and fenders arrive primed and need colour-matched paint — on this car, sprayed silver to match the shell so the flares disappear into the body. The carbon panels are the opposite: bare weave under clearcoat, which looks its best when kept out of prolonged UV, since the clearcoat over the weave is what dulls first. Behind the wheels, the Brembo calipers need the 20-inch diameter and the wheel's internal barrel clearance to sit correctly, which is part of why the build runs 20s rather than a smaller wheel. Done properly, the wheel face sits flush at the guard, the tyre clears, and the brakes have room to breathe.
Frequently asked questions
Will the CT201 wheels fit my Mustang?
The CT201 is built for the S550 Mustang and fits both the 2.3 EcoBoost and the 5.0 V8 GT. Because it is a 2-piece forged wheel, the width and offset are specified to order, so the fitment differs between a standard-body car and a widebody one — a widebody build like this needs more width and a different offset to fill the flared arches. Confirm your exact bolt pattern, brake package and whether your car is standard or widebody with AME before ordering so the wheel is built to the right spec.
What is the difference between 1-piece and 2-piece forged wheels?
Both are forged, so both are stronger and lighter than cast wheels of the same size. A 1-piece wheel has the face and barrel forged as a single part, with fixed width and no exposed lip hardware. A 2-piece wheel, like the CT201, bolts a forged centre to a separate outer barrel, which allows a custom width and offset, gives the deep-lip look with exposed bolts, and lets the outer lip be refinished or replaced on its own if it is kerbed.
Can I choose custom colours and finishes?
Yes. The 2-piece forged build means the face, lip and hardware can each be finished separately, which is how this car runs a gold face against a blue lip with blue lip bolts. The same CT201 can be specified in a single colour or a more restrained combination if you prefer. Finish is chosen per order, so it pays to settle the colourway with AME when the wheel is being built.
Do 20-inch wheels clear big brakes like Brembo?
They do, and that is part of why this build uses a 20-inch diameter. A larger wheel leaves room inside the barrel for a big-brake caliper such as the Brembo setup behind these wheels. Brake clearance depends on the specific caliper and the wheel's internal profile, so the wheel and brake package should be confirmed together rather than assumed to fit.
Does the widebody kit need arch cutting or guard rolling?
The CMST kit uses bolt-on FRP arch flares that build width onto the body, and the side skirts and fenders are shaped to suit them. Depending on the wheel and tyre size you run, some preparation of the guards may still be needed so the tyre clears through full travel and steering lock. This is fitment work best assessed in person against your chosen wheel and tyre, and it is one reason professional fitment matters on a widebody car.
Can I buy the kit and wheels separately and stage the build?
Yes. The carbon and FRP panels and the CT201 wheels are separate products, so the build can be staged — for example, wheels first, then the widebody, or the aero pieces one at a time. If you are staging it, plan the wheel width and offset around the final arch spec from the start so the wheels still fit once the widebody is on. AME can advise on the right order and the matching parts.
