Honestly, I don't think it would make a difference.
In OLR everyone takes it serious and those who don't are the ones who would be clueless enough to try.
Basically, it works like this...
If you win a race- you will be scrutinized.
If your car is high on power or low on weight to any level that will actually provide an advantage, watching the replay in comparison to a similar time as well as the fastest time will reveal your trickery (and inturn you will be banned from racing on the GTP not to mention possibly banned all together).
Furthermore, if your time ends up being the fastest time on the block you better have the name to back it up. It's not like the serious OLR community doesn't already have an idea of where various racers will place in races. We might not know the exact placing but you would be a fool to think the top dogs would be beat and not have the winning racers raise a few eyebrows.
If you try to cheat in OLR you will eventually be caught. It can be detected when a car isn't running proper spec... I had to deal with that problem in the Nurburgring N2 race thread.
Usually sector times are enough to reveal the cheaters and I've seen it done on several occassions.
Bottom line:
If you cheat you will eventually be caught.
If you are caught cheating you risk your membership with the GTP as well as many other forums (oh that's right, the big GT boards are all connected very well when it comes to labeling cheaters).
So, if cheating to win is worth your reputation and online friends then go ahead and gamble it all.
Otherwise, if you aren't interested in hybrids for racing but rather just for the sake of having some fun... Get to it.
Regardless of all of the above, this is quickly becoming a thread where the "hybrids" forum would be most fitting.
