Here is another data point. I installed front camber bolts in my new 2024 GR86 and did a quick DIY measurement of the front camber. It was about -1.5 on each side but I didn't spend much time trying to get a super accurate measurement. I just wanted to confirm that I had indeed produced some negative camber with the new bolts. Then I headed to the local alignment shop.
I asked them to give me as much negative camber in the front as possible and zero toe front and rear.
The final result was -1.5 and -1.7 in the front with zero toe and -1.5 and -1.5 with -0.01 toe which is close enough to zero for me.
Of course, the big question is what exactly did he do? It's entirely possible he threw it on the rack, made the measurements, and handed the keys back to me without ever picking up a wrench. Did he really try to max out the front negative camber or did he just accept what I had already done when I put the bolts in?
I asked the counter guy if I could have a two minute chat with the actual alignment technician and he said yes. I had a twenty dollar bill in my pocket for a "pre-service" tip because I wanted to advise him of the camber bolts and ask him for both a before and an after print out. But the tech guy never appeared. They presented me with an "after" data sheet, but they claim they did not record the "before" data. Anyhow, I'm satisfied with the alignment for a street driven car which will be used occasionally for local autocross events, but I wish customer service wasn't so damned hard to get these days. I still have that twenty in my pocket.
