Grand Theft Auto V Vehicle Upgrade Performance Part Costs: A Comprehensive Guide
In the sprawling, chaotic world of Grand Theft Auto V, your vehicle is more than just a means of transportation—it's a statement, a weapon, and your primary tool for survival. Whether you're evading a five-star police chase, dominating a street race, or simply cruising through Vinewood Hills, the performance of your car, bike, or airplane is paramount. However, navigating the myriad of upgrade options and their associated costs at Los Santos Customs can be daunting. This guide provides a detailed breakdown of vehicle performance upgrades, their benefits, and the strategic financial planning required to build the ultimate machine.
The Foundation: Understanding Performance Upgrades
Performance upgrades in GTA V are tiered, offering incremental improvements for a rising cost. They are available for most ground vehicles (cars, motorcycles, off-road, etc.) and directly impact key attributes like top speed, acceleration, braking, and handling. The upgrades are purchased exclusively at Los Santos Customs (LSC) or, for certain high-end vehicles, within your own Mobile Operations Center or Avenger with the Vehicle Workshop mod.
The core performance upgrades include:
- Engine (4 Levels): Directly improves acceleration and increases top speed.
- Transmission (4 Levels): Enhances gear shifting, improving acceleration and optimizing power delivery at higher speeds.
- Brakes (4 Levels): Reduces stopping distance, crucial for tight corners and avoiding collisions.
- Suspension (5 Levels including Stock): Lowers the vehicle's center of gravity, improving traction and cornering stability. The lowest suspension can prevent roll-overs.
- Turbo Tuning (1 Level): Provides a significant, immediate boost to acceleration.
- Armor (5 Levels): While not a "performance" part in the traditional sense, armor is critical for mission survivability. It increases the vehicle's durability against collisions and bullet damage.
The Cost Breakdown: From Compact to Super
The cost of each upgrade is not uniform; it scales with the base value and class of the vehicle. Upgrading a cheap compact car like the Dinka Blista will cost significantly less than upgrading a multi-million dollar supercar like the Pegassi Zentorno. The following is a generalized cost range for each upgrade type across different vehicle classes:
- Engine Upgrade 4: $9,000 - $50,000
- Transmission Upgrade 4: $10,000 - $60,000
- Brakes Upgrade 4: $5,000 - $30,000
- Suspension Upgrade 4 (Lowest): $2,000 - $35,000
- Turbo Tuning: $5,000 - $50,000
- Armor Upgrade 100%: $5,000 - $50,000
A Practical Example: The Karin Sultan RS The Sultan RS is a popular choice for its AWD performance and customization potential. A full performance build would look something like this:

- Engine Upgrade 4: $39,000
- Transmission Upgrade 4: $40,500
- Brakes Upgrade 4: $30,000
- Turbo Tuning: $40,000
- Suspension Upgrade 4: $34,500
- Total Performance Cost: ~$184,000
This doesn't include armor, weapons, or cosmetic changes, which could easily double the total investment.
The High-End Example: Pegassi Zentorno As a top-tier Super car, its upgrades are at the peak of the price range:
- Engine Upgrade 4: $50,000
- Transmission Upgrade 4: $60,000
- Brakes Upgrade 4: $30,000
- Turbo Tuning: $50,000
- Suspension Upgrade 4: $35,000
- Total Performance Cost: ~$225,000
Strategic Upgrading: Where to Spend Your GTA$
With limited funds, especially for new players, knowing upgrade priority is key.
- Turbo Tuning: For most street cars and sports cars, this is the single most impactful upgrade for acceleration. It's often the best first purchase if you can afford it.
- Transmission: A close second. A better transmission ensures the power from your engine and turbo is effectively transferred to the wheels, especially from a standstill.
- Engine: While vital, the first engine upgrade offers a smaller boost than installing a turbo. Prioritize this after Turbo and Transmission for a balanced build.
- Brakes: Often overlooked but incredibly important. In races, the player who brakes later and more effectively wins. For freemode, it can mean the difference between slamming into a civilian car and smoothly dodging it.
- Suspension: The lowest suspension is generally the best for racing as it minimizes body roll. However, for off-road vehicles, you may want to avoid the lowest setting to maintain ground clearance.
The Armor Question: For freemode mayhem and missions, 100% armor is non-negotiable. It allows you to survive multiple rocket explosions (depending on the vehicle) and keeps you safe from enemy NPC gunfire. For pure racing, where collisions are often accidental, it can be skipped to save weight (though the weight effect is minimal in GTA V's physics).
Beyond LSC: Specialized Vehicles and Workshops
The game's later updates introduced a new tier of vehicles with unique upgrade paths. Weaponized vehicles like the Oppressor Mk II, Deluxo, or Nightshark must be upgraded in an Avenger or Mobile Operations Center with the Vehicle Workshop. These upgrades often include unique performance modifiers like improved boost for the Oppressor or heavier armor plating, and their costs reflect their power:
- Oppressor Mk II Engine Upgrade 4: $195,000
- Oppressor Mk II Brakes Upgrade 4: $120,000
These costs are exorbitant, often running into millions for a full upgrade, making them a late-game investment.
Maximizing Your Investment: Tips for Saving
- Wait for Discounts: Rockstar frequently offers weekly discounts on specific upgrade categories (e.g., 40% off all engine upgrades). Patience can save you hundreds of thousands of dollars.
- Know Your Race: Don't fully upgrade every car. Focus on a vehicle for each major class (Super, Sports, Motorcycle) that you enjoy racing with.
- Prioritize: Follow the strategic upgrade order. You don't need a max-level engine if you're still running stock brakes and transmission.
- Efficient Money Making: Invest your upgrade money into businesses (CEO Cargo, Nightclub, Acid Lab) first. These will generate the income needed to fund your automotive hobby sustainably.
In conclusion, mastering the vehicle upgrade system in Grand Theft Auto V is a core part of the gameplay loop. It requires a significant financial investment but pays dividends in performance, survivability, and sheer enjoyment. By understanding the cost structure, upgrade priorities, and strategic money-making methods, you can transform any ordinary vehicle into a dominant force on the streets of Los Santos.
