Leans to the right

Hello All, Quick question about my suspension. I noticed my 82 spider was leaning slightly to the right, less than an inch measured from wheel well edge to floor. My mechanic, whom I trust, recently changed my worn sway bar bushings and recommended changing my performance (yellow) springs, which lowered the rear end a bit, back to stock (black) springs. He's an old school Alfa Mechanic. (He also replaced missing rubber bushings in the top spring plates.) With the change to stock springs, he brought the car up to level, front to rear, but it still leans to the right. I didn't notice it right away and have yet to mention it to him. I've read about this leaning tendency on the bulletin board that this difference allows for the weight of the driver. Does anyone know if this is a normal set up or does this condition need to be corrected? Also, if two new springs were installed, both sides being equal, what could be causing the difference?

The Passenger side requires a deep spring pan the drivers a shallow there is approx 8- 10 MM more depth in the right spring pan... compensates for driver weight being always on left.

hope this helps..

So if it's leaning, the spring pans are reversed?

Not necessarily but should be checked he may not have ordered the correct spring pan for the passenger side (Deep)

The left spring pan is shallower than the right so the car leans to the right until you sit in the driver's seat. Then your weight will change the stance. The gas tank is also on the left and filling it may also help make the car sit up straight

Lately every thread on this subject ends up being totally confused for some reason.

Assumption 1 - please correct if wrong: this car is left-hand drive.

Assumption 2: "Right" = passenger side.

If these assumptions are correct then the OP's car is lower on the passenger side.

If all of that is correct then installing a deeper pan on the passenger side will make it lean even farther to the right.

My guess is that the spring pans are correct so the car is slightly lower on the passenger side AS DESIGNED.

Also: did you go back to stock springs all around or just out back? You should do all around.

well you may disagree with this but the deep spring pan goes on the passenger side regardless of the LHD RHD... of course on a GTA I would believe they are dialed in as equal as you can counterbalance...fuel etc hmmmm which side is the gas tank on....drivers ...well thats 60 pounds right there isn't it...you must be an expert...trust me I am not confused...

All assumptions correct, Chris. It is slightly lower on the passenger side. And if this is by design, then that's exactly what I wanted to understand. It's not a problem, it's a feature! Thanks for the clarification.

I do agree all the springs should be of the same series

So how the heck is putting a DEEPER pan on the passenger side going to RAISE the passenger side? That makes absolutely no sense at all.

Geometry and weight distribution...I set up a number of these the cars were relatively level...Including a GTA with centered gas tank... i also load the suspension with average diver weight before I tighten up the control arms and the rear trailing arms...and I agree the springs should all be a calibrated set on all 4 corners...

Despite differences of opinion, you guys know a bit about this stuff so I'm in deep water here but the consensus is that I need to now put stock springs on the front to match the rear? How does that affect the front end height of the car? Right now it seems fairly level front to rear. To complicate matters, I have different size tires, front - 195/60/15, rear - 205/55/15 (I know but the car came that way). I'm planning to change these to 195/60/15 all around. Or with the increased height, do I now go with 195/65/15 to fill up those wheel wells? Can of worms.

I know all about the different pans, Tom. I had to swap a pan on my own car to get it right. The deep pan goes on the passenger side to "lower" it relative to the driver's side so it sits relatively level with the driver in the car. It doesn't raise the passenger side. It just doesn't. Interestingly I believe there is more going on than just the pans with side-to-side ride height. And in later years it appears they came out of the factory "wrong" with shallow pans on both sides. Do a search for spring pans with my username if you're interested in these topics.

Going to stock up front will raise it a bit. Thats OK though - proper stance for the car is with the rear is a bit droopy. There are normally spacers in the front that you could eliminate perhaps....

Here, this thread discusses all of this....

Can you mix up the spring pans?

Sfizio,
I believe the recommendations for a matched spring 'set' front and rear concerns giving consistent behaviour for all-round handling balance - shouldn't affect side-to-side ride heights.
