Why does the weight go up on some cars when you're switching from AWD to RWD?

Makes no sense! I was upgrading my skyline R32 and my Mitsubishi GTO for some lobby racing, and I noticed this. Kind of frustrated me a little bit because tuning AWD isn’t in my nature, but in this case, I wanted to stay in the 2600-2800 lb range.

for game balance, they nerfed conversions. They nerfed the wrong thing.

In forza 3 you had to awd swap cars to be competitive in most classes.

In forza 4 you had to rwd swap cars to be competitive in most classes.

Solution: increase the PI for both across the board to prevent the backlash associated with both.

Result: all drivetrains are competitive once again.

New problem as result: certain engine swaps dominate.

I disagree with the bold part, All drivetrains are competitive if you stick with the original drivetrain. It’s not fully fixed, I’d rather have all drivetrains and all drivetrain swaps competitive.

lemme guess, the ls3 6.2 v8 tends to work well?

i found that the new drive model, rwd cars a bit harder to handle but once you got it down pat, you tend to do quite well?

i personally havent found 4wd to be that useful as opposed to FH2 that needs it for weather and offroad which obviouly F5 doesnt have

i dont use fwd

It can be useful for quick corner exits at tight tracks like long beach and nurb gp. From C to S class, awd cars (the ones that are such in stock form) are quite good and with a proper engine choice they can run top 50s-200s. Yes, the V8 and rally motor swaps are what are used to get them really fast though Raceboy has a killer evo 6 in C class and it doesn’t sound like the V8 is in it.

It is a bug that was never fixed.

There is no logic behind it.

Not so. Most 4x4 configurations utilise a transversely mounted engine and gearbox (light and compact) and a small directly driven transfer box delivering drive to the rear. To change to RWD it would be prudent to run the engine longitudinally using a conventional gearbox driving a much heavier diff and rear drive shafts. In reality there probably wouldn’t be much in it but the RWD would in many cases be heavier. There are exceptions to this, such as Lambo’s that start life as 4X4. However, if you loose the transfer box (to the front), front diff and drive shafts you now have to make the prop shaft, rear diff and half shafts capable of dealing with all of the power and torque and this will add weight. No such thing as a free lunch and I think the developers aren’t a mile away with the calculations.
