What pads do you use? In my experience the biggest change on stock braking can be felt with upgrading to different pads. I’d suggest picking a nice upgrade street pad, not a track pad. If that doesn’t fix what you describe then I think your expectations don’t match the car. It’s a 30 year old car that is not boosted like cars from today, that sometimes almost go to ABS-triggering braking power just by looking at it. Not sure if throwing hundreds, if not 1000+ pounds in for 6 pot brakes etc would be the right or any solution. If it’s really a dealbreaker, perhaps try an NC?
