Exhaust v1.2. I wasn't happy with how loud it turned out despite the mufflers. I'm sure the 3" exhaust isn't quieting it down at all, but the mufflers are Borla Pro XS which are supposed to be a "quieter" muffler. So, I added a inline chambered muffler from Remco which toned it down a bit. It sounds less like a dumpy bass drum now. The reason for the 3" is that I plan on going turbo next year and figured I'd set myself up for it.

I’m including another article by Huibert Mees. In this article he explains why lowering a car even 1” can have substantially negative effects. All things I have said for decades as well as here recently. The one thing that is not touched upon is lowering the CG without lowering the car!! What happens then? I explain this in my member's post, last Indian, a ground pounder build. The short version is there are ways to move weight & add weight all below CG. When this is done correctly this lowers the CG in a good way without impacting roll centers or suspension travel! And in doing so you may be able to move weight in such a manner like I did to affect weight distribution as well, depending on how you do it. https://www.theautopian.com/heres-how-lowering-a-car-can-ruin-its-handling/

Probably just due to manufacturing issues or Chevy didn't have a need for a car that sized right away in 1988. There were no sedans in 1988 only coupes. Sedans started in 1990 so that might have something to do with it. GM had a lot of issues getting production going with these cars back then. Doraville, GA is where the Cutlass Supreme and later the Lumina in 1990 were assembled. There was a massive retooling going on and there were issues on the line. These cars were all new and GM already put billions into getting these cars built. GM did have the Beretta at the time, so the need for another coupe in 1988 probably wasn't too high on the list.

So I will first start by recognizing that most will doubt what is presented here so I will attach links to some videos from Huibert Mees. He is a renowned suspension engineer, who has done chassis designs for Ford, Tesla & others. I refer back to my earlier post. Most think they know suspension, they think springs, struts, sway bars, (but never think of link ends) & maybe a few other things! And as such think they understand how to build a suspension. If the body rolls it must be springs or CG! So the first order of business; they lower the car’s CG by using a shorter spring! Terrible idea! Why? Even an inch or two down impacts the roll center negatively, while reducing the suspension travel! I am not comparing myself to Huibert Mees, but I have designed suspensions among many other mechanical devices for more than 50 years & have many patents. So I’m not trying to garner accolades. There are so many things to look at with a suspension, but if I pick just one thing to affect cornering & more specifically high speed cornering, it would be sway bars & their end link! Yet many ignore sway bars as a remedy. Even more so, most never consider their relative size vs end link size! If, I simply said to you, have you ever heard of Archimedes & his statement of "Give me a lever long enough and a fulcrum on which to place it, and I shall move the world." You most likely would say yes! Well to a degree this is your sway bar & end links! Do you honestly think a bar, aka lever, 4 feet or longer & ¾” or more in diameter; in some cases as much as 1 5/16”; can be effectively applied by a secondary lever that is more than 3x smaller!? In some cases like the solid aftermarket front bar of the W-body ll more than 4x smaller. If you did the section modulus of the two you would find the numbers even more staggering! Amanita, without seeing your setup I would be guessing, but by your pictures several things appear to be part of the cause, but all point possibly to two issues. The sway bar & weight distribution. It has been many years since I have worked on one of the first gen W-bodies. So please correct me where I am wrong. Doesn’t the front bar end point attach into a u bracket & rubber bushing? Similar to how the bar attaches to both sides of the frame? If so, the bar as the rectification point! I can explain how. The second is the weight distribution. These cars, as most should know, have a horrible weight distribution. Again there are ways to affect this if you want to put in the work. Last the rear leaf. This can be improved, but it will take work & if you can’t do that work I doubt it is worth it to you to pay to have it done. Last I will attach some pictures, sketches & links that may explain things better, especially the jacking force. The picture of you car is presenting your jacking issue.
