Only when they're making a really, really serious sports car.

The engine on an FD is very offset to the right when facing the car. The battery is also on that side. This was done for RHD cars to improve weight distribution and make room for the steering column. It wasn't reversed on LHD models, so they actually handle worse. I think Mazda knew it wouldn't sell as well overseas so they didn't give a fuck.

I love my FD

>>17749570
For instance, the black part on the top in that pic is the intake manifold, which is shaped like a snorkel on a rotary. The engine starts about where the leftmost part of the engine is. If you drew a center line through the car, there would be 1/3 of the engine on the left of the line, and the other 2/3 on the right (as well as the battery, power steering and ac pumps)

>>17749599
Leftmost part of the alternator*

>>17749050
Honda actually did this with the Integra Type R with the car being perfectly balanced on all four tires only with a 100 kg person sitting in the driver's seat.

>>17749612
Also readjusted for LHD? That'd be fuckin neat actually

>>17749050
I'm pretty sure most manufacturers do that, what I noticed on my little Citroen, which only weighs about 1 Ton, is that the driver side is slightly higher up than the passenger side so it probably evens out with a driver in the car.

>>17749662
Yeah, only they balanced it for a 200 kg person instead.

>falling for the fucking meme

The entirety of the "LHD FDs dont handle as well" is fucking speculation. There aint any proof of that. The offset is so fucking minimal and easily fixable that it doesn't matter much, and if you want to go for full 50/50 left right distribution then being a pound extra or less on the driver or fuel or having a passanger will fuck that shit anyways.

You are being nitpicky with LHDs FD.

>>17749050
They should. Specially for light cars. When tri-seat cars with middle seat for the driver become available we might see even lighter cars based on formula 1s.

>>17751152
it's yellow range for whoever isn't a manlet, are you trying to support my argument or what?

>>17751182
Any BMI over 25 is noticeably overweight.
At 6' It's fucking 30, and everyone knows outside of America the average height is 5'6" for males.
So that means that asians would assume a BMI of 37 for its average drivers, sounds like they've got an obecity epidemic over there.

>>17751167
I'm not falling for any meme you retard. I noticed myself and have talked with tuning shops and retired rotary mechanics who confirmed with me. You're mad that the RHD FD is superior in every single way, lmao.

>>17749819
good lord

Racing teams literally spend a shit ton of time trying to perfectly balance the chassis of their cars, trying to bring the weight as close to centre and in as small of an area as possible. You can't say this has no effect what the fuck go swap an ls1 into your fc because you're a retard

Not the person you're responding to. But you didn't notice it yourself, any difference would be so negligible you'd never notice. Things you read on an RX forum do not count as tuning shops and rotary mechanics. No one confirmed anything with you.

>>17752140
No you didn't. Unless you are genuinely an overweight fuck any difference will not matter because the suspension will take it. And if it doesn't, the tires will.

You either need to lose weight or you fell for the meme.

>>17753009
that's all fine and dandy when you're stationary, but once you start moving the center of gravity matters

>>17753089
Again, your suspension and tires take care of that. If they didn't every single pound of the driver, passanger, equipment and fuel would matter.

>>17753933
You're fucking stupid. The average weight of a driver is never a significant part of mass of the vehicle nor the center of gravity.

If it was, engineers would have discovered this years ago and compensated in the suspension or weight distribution of the car. But they don't at all because it's a non-issue

>>17753954
just an example that center of gravity matters, even if suspension is good
why do you think race cars are so low and wide? Why do you think they have more camber than street cars? Stability, that's why. And also ground effects but that's another thing altogether.

>>17753980
Exactly my point when I said "if you're not a manlet"

>>17753998
Because the average daily commute and his car is not an f1 car whose entire engine and transmission is thrown away between races, the car is preheated so the oil is thin enough to flow through the incredibly narrow oil system and whose wheels and brakes undergo so much stress they catch fire when they go for pit stops

>>17753981
It's a non-issue in heavy cars. OP gets it, he even said "in a super light car". 100 kg matter in a car, specially if it's under 1000 kg.
>>17754012
what does that have to do with suspension and handling?

>>17754017
>It's a non-issue in heavy cars
It's a non issue for virtually every street legal sports car too.

If this was an issue you'd see it in your tire wear but you don't at all

It means the drivers weight in a commuter car is insignificant

>>17754029
Too bad handling, stability and the tires experience an insignificant amount of adverse effects because of the weight of the driver.

In every common commuter car you'll find that the suspension set up is literally the same between both sides of the car. Same spring rate, same dampening, bound and rebound, same toe, all that shit

>>17754029
Handling is impacted insignificantly

>>17754033
only while commuting, i.e. when handling doesn't play a role at all

>>17754066
wrong, there's a reason why teams require drivers to keep themselves a certain weight
>>17754069
nope, they do because of stability
when designing for handling you want a wide stance and a low center of gravity that's as close to the center as possible

>>17754077
>wrong, there's a reason why teams require drivers to keep themselves a certain weight
Insignificant in every way.

The driver isn't going to be 200kg he's going to be 95kg at best. Even then you aren't going to lose a race because you split hairs over 1kg on a driver's belt. You lose a race because of the drivers ability to begin with.

OH man you're really splitting hairs on some severely obese driver and your applea/oranges comparison with race car driving where you magically think insignificant forces magically matter more in physics than anywhere else.

Pleas do this.

Calculate the difference on raw accelerative force between two cars whose mass differs by a mere 5kg. I guarantee you it's insignificant to the max speed or the max acceleration

>shucks man we would have won if you didn't eat a burger last night

Would have won if they didn't out too much fuel in the car on that last stop. Would have won if the driver didn't take the turn as wide as he did. Would have won if he got to slip stream quicker on the straight. Would have won if the engineer shaved off another thousandth of an inch off the engine material . Would have won if they had a better strategy

this is why you don't get it. Weight distribution matters.

>>17749050
I remember watching somewhere that the Nissan R35 was not only 50/50 weight distributed between front and back wheels, but was also 50/50 between left and right wheels.

Not sure if they took the driver's weight into consideration. Not even sure if the Nissan is really 50/50. I dont believe it t.b.h.

>>17754112
Yes it is a coincidence. I guarantee you the engineers for that car didn't have an off center engine because of the driver weight.

>>17754121

Wow two completely different fucking cars. I bet one driver was a fat ass and the other was anorexic.

You can do simple physics on cars. Hold all other things constant and calculate the difference on 5kg.

>>17754117

I'm talking center of gravity in general. The idiots at Audi think it's a good idea to put the engine ahead of the front axle.

>Not sure if they took the driver's weight into consideration
They didn't its insignificant >>17754130

The weight of a driver will not offset the center of gravity significantly

Please spare that extra chromosome to someone that needs it.

>>17754147
laterally, it will

>>17754154
No it won't. It's an insignificant part of the cars weight and lateral movement.

If it was you'd see direct evidence of compensation where the left and right sides would have different suspension set up. If the driver weight has a significant factor so would the rest of the cars compensation be equal to that significance. But it's not because it isn't

It's offset because there's a transmission on the left hand side, just like every other transverse shitbox on the road. The car is complete garbage and no engineer considered balance for a single nanosecond while developing that pile of shit.

>>17754814
They offset the engine because the transmission needs room to exist too. On my car, which is a fusion, the engine is actually on the drivers side, although it's hardly designed for going any faster than about 70 and handles like utter shit but i doubt either are the fault of the engine placement and more the fault of ford making a car for people who hate cars.
