More engine upgrades

Hi. I’ve been playing Forza Horizon since 4 and release on Steam, then in 2021 I bought Horizon 5. I have a suggestion in the upgrades and tuning. It would be nice if you guys add more options in the upgrades and tuning of the engine such as for example a supercharged car like we get an option to change the supercharger belt pulley for more boost and power, also adjusting the RPM shift points of where and when the gears will change, supercharger size like for example a 2018 Mustang GT 5.0 supercharger size like 2.3L, 2.9, 3.0 and 3.8L and so on, turbo size for more power and turbo tuning to adjust the boost to turn the power up more. Another thing is the upgrading of tires and rims. Would be nice if you guys put an option like for example I want to build a drag / street car and a rear wheel drive. I want only the rear to have different tire compound, rim and tire size for better traction and so on. I think it would be cool if you guys gave up options for separate tire compound at the front and rear. Since this is no longer possible in Horizon 5 pretty please make this happen in Horizon 6.
