The new sound are great. Especially the open wheel cars such as FOX.

The only down side for me with LFS is when the car comes lose, if you correct it, it isn't usually the best option but to just leave the car going straight which is not realistic. But once you get the hang of it its fine.
The other one is damage. Open wheel, real life if you'd make contact, your wings would fly off etc, on LFS they just bend like a front bumper would.
Then the crashes. When ever someone crashes I just piss myself laughing, I can't help it, the crashes are so over the top and funny. I can see why so many people crash...
Other then that I have never had so much fun online gaming. LFS has introuduced me to online gaming and other then what I mentioned above, it's great. Not that they are bad, just that is the only areas really where LFS tends to drift slightly from reality.

I also race in the same class as Kieran now...

I race in senior TKM 4 stroke that's why my name is 21 TKM 4 stroke when i'm raicng..on LFS
