Why wouldn't you just take it to a service center? Too far away?
I should ask service techs. The only service person I talked to was a rep, and he said it was not an adjustable part. I'm wondering, however, if it is a replaceable part, like a shock that absorbs more.
How about a cigarette lighter?
I am interested to hear more about Ulmo's bouncing. Is it the rear or front suspension?
I don't know. It may be both. I get some resonance amplification, on occasion, where the back will be going up when the front is going back down, and both hit waves in the road where prior heavy vehicles (cargo trucks and all traffic) worked the original bump into waves, and my car will just go nuts for a second. But when it's not resonating, they feel about equal, too.
Today when I started to drive it, it was smoother (acceptable, even) for 8 minutes, then it got bad. I'll have to revisit those pieces of road to find out if I just hit a smooth patch for a while.
This is probably the key. Model Ss
are notoriously underweight cars, after all.
Humor aside, I decided to look.
I should verify at a CAT scale, but so far I found curb weight of Model S60 is 4,323 pounds, from a forum posting. So, I can haul 1,400 pounds of people, groceries, charging cords, luggage, and other cargo.
Curb weight of my MB was 3,461 pounds from Google search. That's a difference of 862 pounds.
One posters says about 100 pounds of battery per 5kWh. I test drove 90's. That's 300 pounds more. That doesn't sound like a lot. It's 6 50# sand bags. It should be relatively cheap to test, anyway. In the rear, I can deduct my luggage weight, and get away with 1 sand bag. The drunk would receive 3. All at lowest point. You're right, I don't think making the vehicle weigh more will help. But when I used to drive cargo trucks, they always handled better and smoother fully loaded to design specifications.
