Default Different clearance driver/passanger side

hello!

I have a problem and i have no idea why!

I installed in my 97 SC400 Bilstein Shocks with original Springs from the Supra, its fine, front side the spring dish 16mm lower and rear 6mm lower, looks and drives perfect, BUT on the passanger front side, the SC is 10-13mm higher as on the driver side. Why? All values, measurements the same as on the driver side. i changed also the suspension strut driver/passanger, the same value again. Today, i lowered the spring dish 6mm on the passanger side, a little more lower, but not the same high as on the driver side.

A friend have 99 SC400, his car is original and on the passanger side also 10-12mm higher as on the driver side. Is this normal? can i fix this problem only with maybe a Tein Flex

Is this problem also with lowering springs? Can someone measure his car?





Thanks!

Tom

I'm pretty sure this is common with all lowering springs. Mine are the same way, I have Espelirs, and they're probably 5-10mm higher on passenger side front. I took it to my mechanic and he said it's because road designs curve to the right, to help avoid flooding and what not... it's basically so your car still feels even while driving on roads that are curved

I'm sorry, but what your mechanic is saying is completely nonsensical.

I don't know how the roads are built where you live, but most roads I've driven on are slightly raised in the middle, so that water is dispersed to the right AND to the left. We drive sport coupes. This means that there is a high probability that a sport coupe will spend a majority of its time in the LEFT lane of a highway or major road in either direction.

Let's for one second pretend that your mechanic is correct, it would mean that our cars would be leaning disproportionately to the left! That doesn't make any sense to me unless there was a "fat girlfriend" suspension option that I was unaware of.

The JZA80 chassis is known to flex over time.

Pretty common with most vehicles to do this, I dont think there is any real explanation for it other than "thats how it is" haha

Well, you proved my point exactly. The highway is raised in the MIDDLE, sloping down to the LEFT and RIGHT, which means, assuming of course you drive on the correct side of the road, the highway is always slightly sloping towards the right, regardless of what direction you are traveling in. At best, the far left lane may be the most level, but it is still slightly to the right. The flattest, most even area of the highway is going to be where the center median is. This is not rocket science to figure out.

My advice to you is that if you find yourself in the left lane, and the road is sloping toward the left, you are probably a few seconds away from a head on collision and should pull over immediately.

To the OP, again, that's why you're a little higher on the right, so that the car feels even at all times. I worried about this for awhile too!

Your logic is flawed, because in your example you are only thinking about single lane highways. When I say "left lane," I mean the left lane of a multi-lane highway. Here is a visual:

I was thinking exactly of what you took the picture of. It doesn't raise in the middle going both directions, or the medians would get flooded to hell. It just raises in the middle of the whole road. which that picture shows. when you are in the left lane of a multi-lane highway, like the one above, you still are going to be leaning to the right a little bit.
