Awesome information as always fifty inch. Big props to you for sharing this.

Anyone who wants to become a better tuner on Forza games needs to pay attention to this man and his knowledge of tuning. 2nd to none.

I've split up the tuning guide in separate pages for each part and added a little navigation to make it easier to digest.

Well at least the desktop version, mobile version to follow soon.

I've added some stuff in Part 2 - General Tuning that I missed in the first iteration:

Springs:
Added more detailed information how aero affects springs
Added overview of downforce levels for stock, street and sport aero kits

Dampers:
Added more detailed information how relation of front and rear spring rates affect relation of front and rear dampers

Gearing:
Added section for cars with Standard Forza gearbox and 3,4 or 5-speed sport gearboxes

Again only on desktop version, mobile follows soon...

Little edit:

High Performance Cars (super cars and hyper cars) are now separately addressed instead of being described as part of normal production cars.

I've never paid too much attention to off-road cars in Forza 7 but as of recently when trying to tune the Ariel Nomad I've came across about some important differences when tuning off-road cars compared to road cars especially when it comes to brake and differential tuning.

I've updated part 1 and part 2 which now separately address tuning of off-road cars.

I've updated Part 2 - General Tuning with some more stuff that I embarrassingly missed in the past.

Alignment:
- Off-road cars require lower caster than road cars
- Open wheel off-road cars and off-road race trucks require front toe-in

Tires:
- High performance cars and race cars require higher tire pressure than road cars

Brakes:
- High performance cars, race cars, trucks and open wheel cars require more braking force on the rear and higher brake pressure than road cars
- Off-road cars require more braking force on the front and lower brake pressure than road cars

I've updated Part 1 - Forza Tuning Basics with regard to road cars. I split up road cars into utility cars (vans, SUVs), street cars and sports car as they all need a slightly different way to be setup.

Also I've updated Part 2 - General Tuning with two new aspects regarding brake tuning (which turns out to be more complex than I originally thought):

Brakes:
- AWD cars require more braking force on the rear and higher brake pressure than RWD cars
- FWD cars require more braking force on the front and lower brake pressure than RWD cars
- Utility cars (vans, SUVs) require more braking force on the front and lower brake pressure than street cars (but more braking force on the rear and higher brake pressure than off-road cars).

It seems I missed some more stuff when it comes to tuning for FWD and AWD cars.

I've updated Part 2 - General Tuning with regard to tire pressure and gearing tuning of FWD and AWD cars and generally made separate paragraphs in each tuning section for FWD and FWD cars when applicable.

Tires
- FWD cars require lower tire pressure on the front and higher tire pressure on the rear as compared to RWD cars
- AWD cars require higher tire pressure on the front and lower tire pressure on the rear as compared to RWD cars

Gearing
- FWD cars require lower final drive than RWD cars
- AWD cars require higher final drive than RWD cars

I finally found the time to update Part 4 - Track Specific Tuning with regard to temperature tuning that I figured out a while back.

TLDR;
Forza distinguishes between four different temperature conditions:

High: for very hot regions like Dubai or Yas Marina
Medium High: for warmer regions like Suzuka or Long Beach
Medium Low: for cooler regions like Nurburgring or Spa
Low: for cold regions like Bernese Alps

Cooler temperature require lower tire pressures and a softer suspension setup. Warmer temperature conditions require higher tire pressures and stiffer suspension setups.

I've updated Part 5 - Balance and Stiffness Tuning with some more stuff I figured out. It is now generally distinguished between general and track specific balance and stiffness issues.

General Balance and Stiffness Issues:
- added balance issues caused by transmission not matching the cars power
- added balance issues caused by side skirts upgrade

Track Specific Balance and Stiffness Issues:
- added balance issues caused by transmission not matching the tracks transmission requirements
- added balance issues caused by front and rear aero upgrades not matching the tracks aerodynamic requirements
- added stiffness issues caused by chassis reinforcement upgrade not matching the tracks chassis stiffness requirements
- added stiffness issues caused by tire compound not matching the tracks tire compound requirements

I've updated Part 5 - Balance and Stiffness Tuning with some more stuff I figured out.

General Balance and Stiffness Issues:
- balance issues occur when the transmission doesn't match engine upgrades
- balance issues occur when the tire compound doesn't match chassis reinforcement upgrade

Track Specific Balance and Stiffness Issues:
- balance issues occur when the tire width doesn't match the tracks tire width requirements

I've updated Part 4 - Track Specific Tuning with regard to night and rain tuning.

TL;DR

Night and rain conditions require a softer more understeer setup than day and dry conditions.

I've updated Part 4 - Track Specific Tuning with regard to differential tuning.

TL;DR

Every track in the game has one of the four differential profiles:
High: mostly straights
Medium High: more straights than corners
Medium Low: more corners than straight
Low. mostly corners

Cars with 400hp or more power require extra stiff and understeer setup with higher camber on tracks with High or Medium High differential profile.
Cars with 400hp or more power require extra soft and oversteer setup with lower camber on tracks with Low or Medium Low differential profile.

I've completely rewritten Part 3 - Grip and Speed Tuning.

TL;DR

There are now 4 basic setups described:
Grip: for high grip tracks
Medium Grip: for tracks that favor grip over speed
Medium Speed: for tracks that favor speed over grip
Speed: for high speed tracks

Also tuning for Full Grip and Full Speed builds is addressed:
Full Grip builds are considered builds with maximum tire width and sport or race chassis reinforcement
Full Speed builds are considered builds with power that exceeds stock power by at least 100hp and with stock tire width and sport or race chassis reinforcement

Full Grip builds require extra soft and oversteer setup
Full Speed builds require extra stiff and understeer setup

I've updated Part 2 - General Tuning and Part 5 - Balance and Stiffness Tuning with regard to mid and rear engine cars.

TL;DR

Mid engine cars require reverse setup of front and rear ARBs, springs and ride height as compared to regular front engine cars. Also over- and understeer tuning works reverse for ARBs, springs and ride height.

Rear engine cars require reverse setup of front and rear ARBs, springs. ride height and dampers as compared to regular front engine cars. Also over- and understeer tuning works reverse for ARBs, springs, ride height and dampers.

Also mid and rear engine cars require more braking force on the rear and higher brake pressure than regular front engine cars.

As it turned out tuning of mid and rear engine cars is a little more complex than I originally thought, so I've updated Part 2 - General Tuning and Part 5 - Balance and Stiffness Tuning with regard to new findings concerning mid and rear engine cars.

TL;DR

Mid and rear engine cars require higher tire pressure on the front and lower tire pressure on the rear as compared to regular front engine cars.

Mid engine cars require higher front and rear camber, while rear engine cars require higher rear camber than regular front engine cars.

Mid engine cars require reverse setup of front and rear ARBs, springs, ride height and rebound as compared to regular front engine cars. Also over- and understeer tuning works reverse for ARBs, springs, ride height and rebound.

Rear engine cars require reverse setup of front and rear ARBs, springs. ride height, bump and rebound as compared to regular front engine cars. Also over- and understeer tuning works reverse for ARBs, springs, ride height, rebound and bump.

Mid and rear engine cars require more braking force on the rear and higher brake pressure than regular front engine cars.

Mid and rear engine cars require lower accel and higher decel than regular front engine cars.
