What Goes Into an Aventador SV Build: Tires, Calipers, Exhaust, Emblem
Four jobs on one light blue Lamborghini — and why each of them is harder on a supercar than the same job on anything else in the shop.
A light blue Aventador SV spent a few days with us recently, and the work list looked simple written down: new tires, painted calipers, new exhaust, color-matched emblem. Four line items. None of them are quick on a car like this, and three of them are jobs where the difference between a good result and an expensive mistake is entirely in the prep. Here is what each one actually involves.
The Car, and Why It Changes the Job
The Aventador SV is the Superveloce version of Lamborghini’s V12 flagship — roughly 740 horsepower from a naturally aspirated 6.5-liter that pulls to around 8,400 rpm, all-wheel drive, and about 3,360 pounds of dry weight. Lamborghini built it as the sharper, lighter, louder Aventador, and every one of those design decisions makes ordinary shop work more involved.
Carbon fiber body panels do not flex the way steel does. Carbon-ceramic rotors and their calipers are not something you casually pull off in a driveway. The rear tires are wide enough that most tire shops in town simply do not stock them. And the ride height means the car cannot get onto a conventional lift without ramps and a lot of patience.
Tires: The Rear Rubber Is the Hard Part
An Aventador runs a staggered setup that is dramatic even by supercar standards: 255/30ZR20 up front and 355/25ZR21 at the rear. That rear tire is over 14 inches wide. It is not a size you find on a shelf, it is not a size a standard tire machine handles gracefully, and it is not a size you mount without the right clamps and a very careful touch on a $4,000 forged wheel.
Two things drive tire replacement on cars like this, and only one of them is tread depth:
- Wear — a driven Aventador can go through rear tires in 5,000 to 8,000 miles. The all-wheel-drive system and 690 lb-ft do not negotiate.
- Age — far more common on garage-kept exotics. A car with 6,000 miles can easily be riding on six-year-old rubber. The compound hardens, wet grip falls off a cliff, and the sidewalls start to check whether or not the tread looks new.
Check the four-digit date code on your sidewall. If the second pair of digits puts it more than about six years back, the tire is done regardless of how it looks. On a car with this much power and this little weight over the front axle, that is not a conservative recommendation — it is the whole safety margin.
Painted Calipers on a Carbon-Ceramic Car
Caliper painting is the modification people most often try themselves, and it is the one we most often get called in to fix. Done with a brush and a rattle can over dirty castings, the finish looks acceptable for about one summer, then it yellows, chips at the edges, and starts peeling off in sheets around the bleeder screws.
Done properly, the calipers come off the car. They get stripped, media blasted or chemically cleaned down to bare casting, masked at every seal and piston bore, and finished in a high-temperature coating that is cured rather than air dried. The brake system gets bled and the torque specs get respected on the way back on. On a carbon-ceramic setup there is an additional wrinkle: you are working around rotors that are both fragile at the edges and genuinely expensive, so they come off and get protected rather than taped over in place.
The reason it is worth doing is visible in the photos. Body-matched calipers behind an open wheel design turn the brakes into part of the color story instead of a dark gap. It is one of the highest-impact visual changes available on a car that is already finished from the factory.
The Exhaust: What a V12 Actually Gains
Let us be honest about the priority order here. Nobody replaces the exhaust on an Aventador for the dyno sheet. A quality valved cat-back on a naturally aspirated V12 typically frees up a modest amount of power — enough to measure, not enough to feel. What it changes dramatically is the character of the car.
The systems worth fitting are valved: at part throttle the valves stay closed and the car remains civil enough to leave a neighborhood at 7 a.m., and when you open it up the valves dump straight through and the V12 does what a V12 does. Most quality systems drop meaningful weight over the factory setup as well, and lighter is never the wrong direction on this car.
Two things to think through before you buy:
- Cat-back versus decat. Removing catalytic converters produces the largest change in sound and the largest change in your emissions compliance. In Missouri, that is a conversation to have with your shop honestly and up front rather than after the fact.
- Drone. Every system sounds incredible in a walkaround video. The one that matters is what it does to your ears at a steady 70 mph on I-64. Ask to hear a car with the system fitted, at cruise, not just at idle and redline.
The Color-Matched Emblem: Small Job, Big Difference
Color-matching an emblem or badge is the cheapest item on this build sheet and the one that ties the rest together. When every accent on a car is either gloss black or body color, a leftover chrome or contrasting badge is the thing your eye keeps snagging on.
The work is small but not casual: the emblem is removed rather than masked around, cleaned of adhesive residue, scuffed and primed, sprayed in the vehicle’s exact paint code, cleared, and reinstalled with fresh adhesive. Matching by eye instead of by paint code is how you end up with a badge that looks almost right, which is worse than leaving it alone.
What Work Like This Costs
Exotic work does not have a fixed price list, but here is the honest shape of it. These are typical installed ranges on an Aventador-class car — parts and labor — and they move with brand, finish, and how much has to come off the car.
| What it changes | Shop time | Typical range | |
|---|---|---|---|
| Tires (set of 4) | Grip, safety, ride | Half a day | $2,400–$3,800 |
| Caliper refinish | Appearance only | 2–4 days | $800–$1,600 |
| Valved cat-back exhaust | Sound, weight, small power | 1–2 days | $7,000–$14,000 |
| Color-matched emblem | Appearance only | 1–2 days | $200–$450 |
The caliper and emblem timelines look long relative to the work involved because coating and paint need real cure time. Rushing either one is how you get a finish that fails in a season.
Thinking About a Build Like This
You do not have to do all four at once, and there is a sensible order if you are spreading it out. Tires first, always — that is a safety item, not a modification. Calipers next, because they are the largest visual change per dollar. Exhaust when you are ready to commit to how the car sounds every single time you start it. Emblems and trim last, once the rest of the palette is settled.
The other piece worth planning is protection. On a car this expensive, having the paint corrected and covered before you start racking up miles costs far less than fixing it afterward — which is why XPEL paint protection film and Ceramic Pro coatings tend to go on around the same time as the wheels and tires.

Frequently Asked Questions
How long do tires last on a Lamborghini Aventador?
A driven Aventador often needs rear tires every 5,000 to 8,000 miles. On garage-kept cars, age usually retires the tire before wear does — check the four-digit date code and plan on replacement around the six-year mark regardless of tread depth.
Can you mount tires on forged supercar wheels without damaging them?
Yes, with the right equipment. Wide staggered fitments and expensive finishes need a touchless or properly padded machine, correct clamping, and someone who has done it before. This is the wrong job to price shop on.
Do painted brake calipers hold up to heat?
They do when the calipers are removed, stripped to bare casting, and finished in a cured high-temperature coating. Brushed-on paint over dirty calipers is what yellows and peels — the failure is almost always prep, not the product.
Does an aftermarket exhaust add horsepower to an Aventador?
A quality valved cat-back typically frees up a modest amount — measurable on a dyno, not something you feel in the seat. Sound, weight savings, and character are the real reasons people fit one.
Will a new exhaust make the car too loud to drive normally?
Not if it is a valved system. The valves stay closed at part throttle so the car is civil at low speed, then open under load. Ask to hear a fitted car at highway cruise, since that is where drone shows up.
Is removing the catalytic converters legal in Missouri?
Removing emissions equipment from a street-registered vehicle is not something we recommend, and it can affect compliance and resale. We will talk through cat-back options that get you most of the sound without that trade-off.
How do you color match an emblem to the car?
By paint code, not by eye. The badge comes off, gets cleaned and primed, is sprayed in the vehicle’s exact code, cleared, and reinstalled with fresh adhesive. Matching by eye produces a badge that is close enough to look wrong.
Do you work on exotics and supercars in St. Louis?
We do — wheels and tires, caliper refinishing, paint protection film, ceramic coatings, detailing, and trim work across all three of our shops. Call ahead so we can plan lift and ramp access for a low car.
