I want to be able to add diffusers
They removed them after FM2. (Race Bumper/ rear diffuser) The RSX sill has a race rear bumper though…
I’m sure its a lot of work but if they gave us 3 or 4 different Race Aero looks to chose from like they do with the muscle car hoods then that would be great. Another ideal would be a custom wing maker like GT6 has on ps3. That way you could mix preset wing parts together and adjust them to fit each car to your liking. (I assume it could be done but it might be a pain in the rear to program)
On a side note: If anyone from T10 is reading this, Can I please have all of my beloved NXS body kits back please!!!

I know it requires work, but the fact that we can put racing tires, brakes, suspension, rollcages, weight reduction, fenders with adjustable splitters, adjustable wings… and still we are one diffuser away from turning every car into a proper race car, kind of rubs me the wrong way.
They deleted them and gave the rear wings more downforce. I guess that was the trade off.
Compared to a high-mounted rear wing, a diffuser is a more efficient means of producing downforce, where efficiency is measured as the lift[downforce]-to-drag ratio.
In other words, a diffuser could give you the same downforce in exchange for less drag, so whoever of you guys that don’t particularly care for the car’s looks, but care only for performance, should be interested in them as I am.
Because less drag means more speed first of all, and for those of you that love endurance racing, greater fuel efficiency. Additionally, if your car tune is very close to the upper limit of its class, being allowed to choose between race rear wing only, or race diffuser+race wing setups could help you create the best car for the class.
There’s no way a rear diffuser can generate as much down force as a fully functional race wing. The diffuser smooths out the are under the rear of the car helping the rear wing product down force. Without it the wing will still make down force just not as much. If the combination of diffuser and rear wing make 200lbs of down force than over 150 of it comes from the wing alone.
Basically they took the looks of the diffuser away and just gave you at ability to add more rear downforce. I’ll have to double check but in early games you had 100lbs. In the last two games most cars have 200lbs+. You lose on performance, only visual…
Now of your talking about a full undertry (flat bottom) then that would be a different story.
I remember in Need For Speed Shift, and the sequel, you could turn every car into a racing machine not only in performance, but also in looks with the bodykit, interior upgrades and works conversions.
I feel Forza is lacking in this area, though to be fair, Shift did have a lot less cars.

I don’t get why they put the wide body kits in Motorsport, what kind of DE’s do they attend that people put those on their cars? I seen flares like they put on a S30 Z, but that is still rare. The forums I follow people are more focused on putting the widest under the the stock fenders for better air flow through out the body of the car and go with APR splitters and wings for proper aero. Even with track builds wide body kits are not even in anyone’s radar. Too much added drag for actual benefit. Also with so much people they claim that play’s Forza I’m sure getting license from APR would be easy.
It may not be Rocket Bunny or Liberty Walk. But the wide body was not a rare existence in the history of motor sports.
The wide body for Skyline KPGC10 added in FH3 is a design that imitated real race car’s.
It gives players new choices and gives the possibility of new upgrades to cars that were unable to fit wide tires.
That would be the right choice as a game.
If you want to race more severely and fair, decide the rules in private, or please head to the real race track.
Also, only the world you know is not motor sports.
WTAC requires wide tires and extreme wings for their performance.
It is the same in the world of drift. A wide body is indispensable to get faster speed and traction.
Don’t use it if you don’t need a wide body or hate a wide body.
People who prefer wide body kit use it. People who don’t like wide body kits do not use it.

Have you ever seen WTAC? Every competitive car at the highest level of the World Time Attack Challenge held annually at Sydney Motorsports Park is running a custom wide body kit with a giant ass wing. The current world record holder is a wide body S13.

Well widebody cars do benefit handling as in general the wider the car the better the handling it has as you can also add wider tires just look at the current gen F1 cars for a example of that. Yes they create more drag but if you upgrade you’re engine you can bypass that to an extent. Also a lot of people widebody their drift cars and as drifting is a form of motorsport it makes sense to add widebody kits. Also the more customisation the better.

Actually aero on F1 cars are designed to flow air around those wider tires because there are so many turbulance created when the air hits the tire and even with wider tires F1 cars are no where considered “flush.” There is a compromise between how wide you go with tires and how much added weight and drag you want. I don’t know about you, but no one goes all out on the motor on DE’s or even track builts. HP creates heat and managing heat takes a lot work especially if you do enduros. I have a friend who particaptes in the 25hr of Thunderhill and he stresses to keep the engine mods simple, do more with less. Also you don’t need a widebody car to drift, ask Tiff Needell, Chris Harris or Jethro… not trying to sound like a track snop, but really being realistic. I for one want more race cars or actually mirror class rules with mod restrictions.
Well yes of course the aero on an F1 car is designed to direct flow around the tire due to the turbulence the tire will make, that’s why the end-plates are angled, why there are veins and wing-lets on the side pod and nose of the car and why F1 cars use blown wheel nuts now. Even the front wing and rear wing is angled back now to distribute the air better and why under-body aerodynamics are becoming more important especially in Indycar where 19% more downforce will be generated under the car in 2018 than the previous year, to minimize drag, distribute the air more efficiently and minimize the effect of dirty air. However I still revert back to my previous statement that the new wider F1 cars have allowed the cars to run wider tires which has improved mechanical grip, traction and high speed grip. At that kind of performance where you have engines producing 1000 Hp and where the cars are still extremely light, you’d rather take the extra weight and extra drag of a wider car with more downforce and wider tires over not. This is evident as on some tracks the new 2017 F1 cars are running 3+ seconds faster a lap then last years cars, even though technically last years cars had less drag, higher top speed, near enough the same horsepower and were lighter than this years cars but mechanical grip, traction and downforce is king at that level of speed and performance. There is a “compromise” of course.
As for endurance racing of course drag and weight put more strain on a car but most endurance cars run some sort of restrictor plate to stop the engine from staining as much and of course usually more HP usually means more heat is generated but once again in endurance racing reliability is just as important as performance so most endurance cars run quite advanced oil and cooling systems. Of course you don’t need a widebody car to drift but when building a drift car it makes sense to widebody it for obvious reasons. I too would prefer more racing and circuit oriented mods but I have no problems with widebodys being added and it makes total sense to me.
A properly designed body kit can actually reduce drag. Newer cars are pretty well made straight off the assembly line but older cars can be like trying to throw a loose grocery bag at a spinning fan. There are several advantages to having a widened wheel base as well, particularly being able to run fatter tires front and rear for increased contact patch with the ground. Older GT3 race cars and even newer ones all show up to the track with “wide body kits” (very well designed). I’m not a huge fan of aero upgrades on any cars because I like to drive the classics and they are too beautiful to slap a plastic flap on the front and rear with 24" cragar Smoothies underneath to get those couple extra PI points to keep it in a lower class. But I still do it because the older muscle cars really need that rear wing. I’m just hoping to get some more options in the next Forza offering.

Horses for courses.
You’d generally flair fenders for wider tires and the advantage of a full wide body kit is increased track and not necessarily wider tires.
Wider tires will (up to a point) increase mechanical grip but wider track would usually result in better handling.
That being said, for pure traction a drag car will run as narrow a track as possible.
Another common reason for wide body kits is to accommodate very non-standard running gear and space frame chassis. A body kit on its own wouldn’t do anything much to improve performance.
In FM wide kits will only be cosmetic anyway so it really doesn’t matter how you build your car.
We’re getting into areas of design that don’t even feature in games but are non the less interesting.
A rear diffuser would do little if anything on its own. It’s only part of the complete underside design of the car stretching from front lip to rear. Everything is designed to accelerate air beneath the car thus creating negative pressure. The lower the pressure under the car relative to the pressure pressing down on the car the greater the downforce. Just adding a rear diffuser to a standard chassis would be a bit pointless.

Even with all the downforce produced by road legal contemporary supercars? I mean the Ferrari F12 generates downforce from of the hood. Not to mention all the moving parts present day cars have like rear wings.
Well, you wouldn’t add an aftermarket diffuser to an F12 or most super/hyper cars as they’re already designed with efficient aero front to rear. The rear diffuser is just the part you see but it’s the entire floor that creates ground effect.

I miss the duct taped headlights that were in either Forza 4 or Forza 5, which could then be painted.
