miller motorsports park and stardust grand prix las vegas

I have tried the MMP road course with a best time of 1:04. Had to really work on the setup to get it. Couldnt do any better than1:29 at first. Has anyone built the original stardust raceway that used to run sports cars in Las Vegas back in the 60s? If so could you please post it on here or email it to mtman77@msn.com. Im also looking for a Gp3 version of Riverside raceway as well. I cant run my GPx in debug mode so it needs to be a track that doesnt require debugging. Also Id like to have the updated Portland track with bridge and no f1 pits if its available. I cant run the debugged version.



thank you for your help
