What did the pan hard bar and lower control arms change in the way the car drove? I’ve been thinking about doing mine since I just did new springs and shocks.

The rear end feels stable more don't feel as flimsy around corners. It'll freak ya out a little bit because it feels like the rear end feels like if your riding on the very back of a school bus. The rear end follows 🤣 🤣 which makes it feel like the rear end is trying to out run the rest of the car. Thats about the best way I can describe it. I wasn't going but maybe 10 mph or so around the block just to see how it feels. I haven't gotten it on the roads yet. Most I got it up to is about 20mph and the car feels solid. Its much more responsive feeling turning the steering left an right real quick. Once I get it on the actual roads where I can hit 35 and above itll be better. But I noticed it right off once I pulled out of my drive way. Has a whole new feeling to it

And Ive got both passenger and driver side set at 7/8ths of an inch so its adjusted like it should be... before I replaced the pan hard bar the driver side was out a inch. And the passenger was in at around 3/4 of a inch

So I took the car out today didn't notice the rear-end follow as much probably being getting broke in a little. But I will say this around corners it rides like your on clouds just smooth bearly any body roll its stable

Been watching your videos a lot lately and I'm getting desperate. Would you be able to help me diagnose a rough idle on a 91 firebird 3.1?

What all have you done to it

[@imnotgivingmynametoamachin1686]

Replaced FPR, replaced IAC, replaced TPS, replaced EGR, replaced O2, replaced any broken vacuum lines, sprayed started fluid all over the lines, tested MAP sensor under vacuum (1.2v at 20 inches, 1.7v at idle, 4.97v key on engine off), new plugs, wires, cap, rotor. Pulled distributor cap and found 5-6 degrees of chain play. Ohm checked the injectors 12.5 and 12.6 across all 6. Car starts and goes to 1500 rpms, slows down to 800 with a slight stumble, when fully heated it's at 700 and rough and will die if in gear and holding brakes. Pulled and plugged the brake booster line, no change.

The injectors were tested cold, not sure how I would test them hot without pulling intake plenum again.
