Upgrading a car

Is there a recommended way of upgrading cars such as the McLaren 12C. One of my friends suggested the AWD swap and then turbos etc., and then upgrading everything else by selecting upgrade furthest to the right.

Everything furthest to the right is usually the Fast & Furious tune… Massive specs but only good in movies and not for driving.

Have you tried reading the numerous beginner / advanced / pro topics about tuning on these Forums (and not just for Horizon but also for Motorsport)?

If your unsure try the auto tuning its pretty good at getting you started

The “recommended” way of upgrading your car is to first determine which vehicle class you want it to be eligible for; then, take in account your driving style and decide if anything should be added to support your technique; then, add upgrades that either compensate for a vehicles’ lack of handling, power, or both.

In short: the art of being competitive is far from simply going with an “AWD swap and then turbos etc.” and “upgrading everything else by selecting upgrade furthest to the right”.

Yah I first pick a Class I want to tune the car for… then go from there. Also depends on what I plan to use the car for, if I’m going to use it on off-road races that would be quite a bit different setup compared to a track car.

I start with handling improvements first, usually brakes, sway bars, suspension and reduce the weight a little. Or if going for the higher classes, A or S classes I use the highest weight savings. This will help handling and acceleration significantly! For A class and above I’ll usually select the best transmission upgrade as that lets you tune your gear ratios. Tuning your gearing can significantly change how fast you accelerate or your top speed.

Next I go for tires, usually just pick the widest tires. Though sometimes for the lower classes you might have to go with narrower tires if you’re trying to fit in a class and balance performance.

Last I tack on the engine upgrades… I generally start with Exhaust, Intake & Ignition first. Next is usually Camshaft as that increases your Redline which can greatly increase your top speed. If you still have more leeway in upgrades for your class, it’s usually just trial & error to find what parts you can bolt on to get you closest to the max rating for your class. Or finding other parts to swap for less weight.

Tuning does take a bit of trial & error there is no perfect solution…

I want the car to go fast but be easy to control, what should I do in that case?

Buy a car with high speed and average handling stats and upgrade the suspension / brakes / weight.

Yet, from the previous replies: you actually need to know what you’re doing. Bolting on bits doesn’t do a whole lot for you as such; adjusting the bits to handle the power / weight / balance is somewhat science.

To put it quite blunt: if you tuning and/or driving skills are rubbish, no car will go around the corner no matter what stats it has.

I have no problem with corners, I just mainly want to improve the top speed but still want to be able to control it.

A good way to begin would be to buy a low-mid class car with higher than average power. Then upgrade the handling of the car and don’t worry about power. If you’re unsure of how specific upgrades affect your car, buy only that upgrade and go for a drive.

There are many threads in the tuning section for horizon 2 and motorsport 5. Take a look around there for suggestions.

Without sitting at my console, here is a suggestion to try.

Car: 69 charger r/t
Upgrade:
Front aero
Awd
Supercharger
Race brakes
Race springs
Race anti roll bars
Race weight reduction
Race differential

Then see what class it in. Add upgrades (race) from the following list (in order) until you are at the top of that class. If the upgrade puts you into a higher class skip it and move on:
Rear tire width
Supercharger
Exhaust
Air filter
Pistons
Valves
Displacement
Rims
Ignition
Fuel
Drive line
Flywheel
Front tire width

Now drive the car and see how it feels. If you don’t the gearing, feel free to remove some upgrades to add one of the transmission upgrades. You may need to tune it a bit, but that’s not required.

Most importantly, experiment and try it for yourself. You won’t figure it out any way.

If I do this, is it possible to get rid of parts that I don’t want?

First, I’d like to make a correction. I typed that on my phone and it omitted a word. It should have read,
“You won’t figure it out any other way”.

Yes, you can always go in and remove parts, they are not there for ever one you them on. You can even have multiple builds for the same car. For example, I have a Maserati 300s in a class, s1, & s2… …I just switch between builds in the tuning menu as I see fit.

I see.

Hi Guys I just Come Across this forum check out my YouTube Channel please like and subscribe I’ve got some builds and tunes on there got some road tunes and off-road tunes going up this weekend or if not add us on Xbox live and I can help u out as much as possible cheers guys hope its some help also Check Out PTG Tuning YouTube Channel

A good rule of thumb is to know what your cars weaknesses are and try to upgrade parts that will improve upon those weaknesses. Also for many cars it’s a good idea to only build them a class above what they are stock but there are plenty of exceptions. For example generally a stock C class car I won’t build higher than a B Class car. I’ve noticed too many people online that think upgrading every car they own to the max is a good idea and then they wonder why they get owned online.

For example cars like the Shelby GT 500, Dodge Challenger 392 and '12 BMW M5 are all cars that already have a high power output and little handling so it’s best to focus on how to get that power to the road with better handling upgrades. What this does is rounds out the overall build and with better handling upgrades you will make better use of the power output these cars have. When upgrading for handling you’ll want to go for brakes, springs, anti roll bars, chassis reinforcement, weight reduction, tire compound and tire width. Forza Aero will also help with better handling.

No matter what car I build with some exceptions I normally upgrade brakes, springs, anti roll bars, chassis reinforcement, weight reduction, tire compound and tire width before I do anything else. Then if I have PI left to spend I’ll use it on power upgrades.

To each their own, but IMO people who automatically do a full S2 or X class build on every car they get are killing the diversity of the car list, and are denying themselves the full experience. Don’t get me wrong, I have a rocket or three in my garage too, just saying there’s TONS o’ fun to be had in slower cars where technique and lines count for more.

whats the difference between Turbo, Twin Turbo, Roots supercharger, and centrifugal supercharger

Please don’t gravedig. That aside,

turbo = hi boost @ hi rpm
twin turbo = turbo x 2
screw sc = standard supercharger, steady boost throughout rev range
cent sc = sound like turbo, but yield boost and act like lq supercharger
