Since I'm seeing a ton of Gran Turismo alumni on iRacing I figured maybe others would be interested too.
A 30 day free trial is available here with a Radical

Great use of your G25 wheel and pedals... :-)
Every review say's the physics are the best available today. It's expensive, but if you're looking for an amazing online sim, this is it. Tons of real world drivers on it. Dale Earnhardt Jr, AJ Almendinger, Justin Wilson, Bobby Labonte, Marcos Ambrose, Martin Truex Jr., Jacques Villenueve, Alex Ardoin and the list goes on and on.
Plus, many sim racing legends like Gregger Huttu, Richard Towler, Volker Hackman, etc.
Many of these reviews are 9 months old. iRacing is subscription, so they've added a ton of new features, cars, tracks since these reviews. Updates every 3 months. They have Yellows, Spotters, saveable replays now and a bunch of new stuff.

Sim of the Year Part Two

...Dave Kaemmer’s online racing magnum opus opened its servers to the public last August (with some financial help from Boston Red Sox owner John Henry) and quickly developed into the go-to place for serious sim racers. The pay-to-play service—which features stunningly accurate laser scanned tracks like Laguna Seca, Daytona, and Sebring—attracts legions of dedicated sim racing hobbyists driving alongside a who’s who of real world racing luminaries like NASCAR superstar Dale Earnhardt Jr., F1 champion Jacques Villeneuve, and IndyCar racer Justin Wilson.
I have no wish to malign Codemasters’ or GRID’s achievement but, speaking on behalf of all hardcore sim racers with a force feedback wheel and pedal setup permanently attached to their desktops, I hereby award an alternate Best Racing medal to iRacing.com for its invaluable and unrivaled contribution to sport of PC sim racing.

Review 2 (opps RSC is down for a while)
RaceSimCentral review by Tony Rickard
iRacing really is the “next GPL”, with the one caveat of increased cost this is the online sim that really should bring sim racers together and provide a route in for new drivers. The lack of AI, modding and the fact the racing is regulated means it won’t be all things to all people but for those looking for the best racing simulation with sanctioned online races then they need look no further.

Nice 20 page review. You'll need to download the PDF to read it.
"Digital Cocaine -
The iRacing team has created a masterpiece. The magnitude of the achievement of this team really hit home for me the first time I drove the Skippy car at VIR. Flicking the car through those high speed esses, hurling it through the fast sweeper in turn 10, power sliding out of the Oak Tree bend, all of it was thrilling. It's hard to believe a simulation can feel this authentic, so amazingly like the real thing.
This similation is astonishing. I've gone back to other sims briefly as a point of reference, and frankly, iRacing has ruined me for anything else. The previous state of the art sims seem toylike, cartoonish.

The Racing
The racing, no doubt, is where this sim shines brighter than anything else for PC or console I can think of.
For die-hard sim racers this is as close to reality as it is currently going to get.
