As yet, nobody has been able to provide one shred of evidence that any of the suspension model is backwards.
LOL
You complete
This goes WAY back, almost to the start of the game... If you haven't been paying attention to WWIII that has gone on about this then don't come on hear spouting your rubbish.

This isn't even the 'start' of it, it goes way back further to when the "SKILLS" Xbox (FORZA) 'clan' gave GT5 a go. They topped the time trials immediately, people started asking questions about their ride height and the "SKILLS" guys explained how the affects on the car when there is difference in ride height (from front to back) was 'reverse' to what it should be. They took this to the extreme with max fr min rr.
Check the 2.08 update thread on this tuning subforum where guys 'checked' and confirmed the same was still happening, well over 1 1/2 years later. The suspenson ISN'T backwards, the ride height ISN'T backwards, but the
affects of having a difference between fr and rr ride heights IS "backwards".
Well over 1 1/2 years and you say there's not a shred of evidence..??
Pffffft, thought I was crazy and on a different planet....
There's so much evidence of this in GT5 it's ridiculous you say this, from the threads about the subject, the tuners who setup their cars like this, the guys who checked the last updates or some of the faster/fastest GTP racers (who run LOWER rears - gee, they're really going to give themselves understeer aren't they?).
For someone with as much xperience of tuning subforum as you to say this, only one conclusion...
MrGrado = blatantly trolling us
EDIT:
Just had a look at some of your "tunes"...
Cizeta V16 '94
600 Performance Points
812 Horsepower
1550 Kilograms
Ride Height: 29 / 32
Sooooooo... a car with serious oversteer, and you RAISE the entire car even more (when most cars in real life are lowered to improve handling or stability) and you have rear ride height higher than front...
Pfffffffffftt - troll-lol-lol-lol-lol-lol-lol-lol
