Car pull to the left

[The Necessary]

Pumping up the air pressure will work because it lessens the tyres' contact patch with the road, hence lessening the grip and effect of the sway.

No BS here; apparently why E46s sway to the left is because they were designed to be LHD cars. All secondary masses (fuel tank, battery, etc., etc.) are located on the RIGHT SIDE of the car, to balance driver weight on the left (hence, it's not only 50:50 weight distribution front/rear, but also left/ride).

And when they engineered the RHD versions, they couldn't relocate those secondary masses without massive investment (new molds, etc.), so they were left where they were and we're left with a slight tracking problem.

But how that exactly causes E46s to sway left... well, why do you think all roti is spun in an anti-clockwise direction?!

also check ur caster angles. differences in caster angles on both sides cld also cause the car to pull a bit more to one side. this is something an alignment shop cant really fix since caster is seldom adjustable except on race cars.

Does the RHD ///M3 have a left drift as well? Just curious

Well, my tyre shop "solves" the problem by adjusting the toe in of the front wheels till it doesn't "drift". So, yes I presume it does so in stock form, though I've not really noticed, since it's something I've been used to and accepted since the days of my 330.

not sure if compensating with toe is the best way since then ur gonna be running uneven toe on both sides. if the pull is very slight and the car still tracks straight when the steering is straight, id just live with it.
