Parts Development

Your car consists of four parts in total: Brakes, Suspension, Gearbox and Engine. Parts developent is separate to the Engine. You can build, upgrade and repair parts while the Engine development follows a different approach.

At the start of the game, you are only able to develop your own Brakes. Suspension and Gearbox are stock parts with set reliability and performance bonuses. You will be able to develop your own Suspension and Gearbox as you progress through the Career Mode.

You can enter the Parts Development tab by clicking on it in the homepage.

## Building Parts

    Building parts requires Cash, Staff and take time. The amount will go up as you upgrade your parts. The higher the level, the more expensive it will be and the longer it will take to build.

You can build as many parts as you like s long as you have cash and available staff.

## Upgrading Parts

    All parts start at Level 1 and can be upgraded up to Level 100. Upgrading will increase the Performance bonus you get from that part.

Upgrading costs Materials. The amount and type of materials will change according to the level of the parts. Higher level parts will require more and rarer materials to upgrade.
Note that upgrading is also capped by Tier, which means you cannot have Lvl 100 parts early in the game, for example. The Performance Cap you have from having all parts maxed out for your current Career level means races against other players will always be as fair as possible.
It is possible to upgrade multiple levels at once, as long as you have enough materials and you are not trying to go above your Tier Cap. If you don't have enough materials, you can purchase them with Paddock Tokens to complete the difference.
Upgrading level by level or multiple levels at once will still cost the same amount of resources so there is no real advantage in saving to upgrade multiple levels at once, at least cost-wise.

## Installing or Recycling Parts

When you finish building a new part, it will sit in the Parts screen until you decide to install it. It will also continue to hold the staff used in building that part.

Installing new parts will always destroy the old part. However, you get some resources back.
New parts always start with maximum performance and reliability based on their levels. Racing will have a wear and tear on your parts after each race, dropping their performance and reliability.
If you build a new part and you do not want to install it because the current part is *better* than the already installed one, you can always recycle it. Recycling parts, just like installing parts, will give you some materials back. This is a good way of farming resources early in the game but note that you will mostly only get common resources from either method.

## Repairing Parts

    After each race, your non-stock parts will take some damage and lose either Reliability or Performance. The amount of damage is random but can be slightly reduced by HQ research.

The amount you can repair your parts for will depend on your Engineer skills. The Performance and Reliability bonuses he/she has are the amount you can repair your parts for.

You should be able to reach 100% Reliability for your parts using post-race repairs. However, it is not possible to boost your Performance past the maximum reliability you had when it was built.
