I ran the Castrol Supra time in a GT2 series, ECC on the granturismo.com board. I had a save at the time, but have competed in over 20 races since then, and unfortunately that run is no longer saved on any of my memory cards.
I am guessing that you Maverick have a dex drive? Is this the type of proof that you have?
If so, then I'll issue you a small challenge. I'll re-run Tahiti in the Supra. I spent quite a bit of time getting the 50.3, but likely can pull off a 50.8 +- or so with relative ease, without cutting too heavily into the time required to run in the series that I am racing in now.
Your part of the challenge is to run at Deep Forest in the Nissan R390 97'. I already have a decent time saved on Memory Card with a clean run, that I would be happy to send to you by dex. I'll give you a week to post your time for Deep Forest.
(Note - some patience would be required, I don't have a dex, but a friend about an hour away does)
I have been running OLR for over two years, and am the moderator for both the GT2 section and OLR at the GT board. We are probably amongst the strictest group against cheating, and as far as I know, have the only published list on know cheaters around. I fully appreciate the nature of cheaters and cheating, and don't really need a lecture on proof of times. While I have become fairly quick there are a number of drivers far quicker than I. You would likely be well served to not act so flippantly to some of those who have been around for quite some time, as you could probably learn a great deal from them.
