Seeking collective wisdom on how to improve handling in a late-model rear-wheel-drive coupe without relying on brand-specific parts. What general strategies have you found most effective—suspension geometry adjustments, weight-shift techniques, tire pressure tweaks, or driver coaching? Are there DIY methods that consistently deliver measurable improvements, or do you favor a systematic approach with incremental testing? I’d love to hear shared experiences and any recommended resources that avoid specific product endorsements. How do you balance cost, time, and performance gains?

I’ve been tweaking a ’19 rear-wheel-drive coupe for a few seasons now, and the biggest gains came from a systematic, low-cost approach rather than hunting for exotic parts. First, I dialed the front camber and caster to the factory specs, then nudged the camber a touch more negative (about –2° to –3°) to improve front-end grip when cornering hard. On the rear, a modest rear-camber reduction (≈ –1.5°) helped keep the tires on the edge of the slip line without sacrificing stability. Keeping the anti-roll bar stiffness modest—just enough to curb body roll but not to make the car nervy—gave a predictable feel and let me fine-tune the balance with spring rates later if needed.
On the tire side, I found that a slight pressure drop (roughly 2-3 psi below the OEM recommendation) at the front and a small increase at the rear gave a more neutral understeer/oversteer split, especially on a dry track. The change is cheap and reversible, and the effect shows up in lap times within a few runs. Finally, I spent a weekend shuffling a few hundred pounds of weight: moving the battery to the trunk and adding a small ballast just ahead of the rear axle helped shift the car’s weight bias rearward, which smooths the transition into throttle-on cornering. Pairing those geometry and weight tweaks with a disciplined driver-side routine—smooth inputs, braking in a straight line, and a consistent apex line—produced measurable lap-time improvements without any brand-specific components. The key is to change one variable at a time, log the results, and iterate; that way you balance cost, time, and performance efficiently.
I've heard that a slight increase in rear camber can improve cornering, but I'm not sure how much tire pressure drop is safe for a street-legal Camaro without losing grip on straight sections. Do you follow any specific front-to-rear pressure ratio that balances handling and everyday comfort?
