Rear Lower Stress Bar Feeler

I can offer my own experience with a strut brace mounted on my 986 for 6 years and 80 track days. I did notice a very subtle improvement in chassis stiffness with fewer creaks going over a swale or up my steep curved driveway. It was subjectively a small improvement, not a big improvement but it didn't cost much so...

Did it measurably improve my lap times? No.

Re: a comparison with a front strut brace? A 986 has a very stiff front chassis similar to a 996 GT3 Cup. No front brace is needed there.

Does it work better on an "S" model than a 2.5L? Lateral G forces are the same on both cars in a corner so there would be no difference. Lateral Gs are mostly a result of tire choice and your suspension's ability to control your contact patch.
