As a hobbyist custom wheel consultant and long-time Forza player, the following has been on my wishlist for years, most likely along with many others in the stance scene.
Not sure about the rules as far as having multiple suggestions per thread go but since these are all so closely related I figured I’d consolidate.
Customizable Lip Depth, Concavity & Staggered/Deviated Wheels
One of the biggest negative side effects of having unrealistic stagger is that some of us will limit ourselves to a narrow selection of wheels that fit the sort of look we're going for while discarding altogether other wheels that are too deep or too shallow (even though the spoke design itself might be preferable).Below I'll detail the different aspects of stagger and how varying offsets play out in real life, and how I hope they can play out in the game too someday.
Lip Depth
The Murcielago is probably the easiest modern car to notice the concept of stagger and the effect of lip depths on. Notice the difference in the lip depth of the front and rear wheels on the real car vs. in-game.Ideally, we'd be able to adjust lip depth and have this be adjustable independently from front to rear.
Concavity
By the same token, some applications use wheels that are concave in nature, sometimes differently so from front to rear, to achieve the same low-offset effect.Ideally, we'd be able to adjust concavity and have this be adjustable independently from front to rear.
Worth Noting
We did have lateral geometry scaling by section width in older Forza games. Horizon 1 pictured. Notice lip depth difference in the 215 section width vs. the 305 section width.HOWEVER, it would be nice to be able to adjust lip depth and concavity independent of the section width like many real-life applications require.
Deviated Front/Rear Wheel Selection
This would be a cool first-time addition to the series. Many applications, especially drag vehicles, call for the use of completely different front and rear wheels.Further Flexibility in Wheel Diameters/Adding The Option to Downsize
Speaking of drag applications, we know more sidewall = more traction but this usually requires the use of wheel diameters that are smaller than stock, especially on modern sports cars.Not to mention offroad builds which benefit from the use of larger sidewalls as well.
This feature is desperately needed on cars like the Civic Type R which came with huge 20-inch wheels from the factory. See below that there is no option available to change wheel diameter...
…yet many IRL owners will opt for 18 or 19-inch wheel and tire packages:
True Directional (Mirrored Wheels)
It would be nice to have the ability to mirror wheel designs from side to side to display the correct true-directional appearance.On the first picture you can see the correct direction of a directional wheel (the secant legs of the spokes are always below their longer counterparts relative to the forward wheel motion of the car)
The spokes are flowing the opposite direction in the second picture which gives a conflicting aesthetic.
In real life, you will often see separate SKUs for higher-end wheels supporting the true-directional appearance.
