I was in the very first D1irl round It was in 2003 - 5 rounds from what i can remember, all in Rosegreen. First round was won by Dmac in an RX7 (matt black with graphics - late 80's car if iirc)

I thought Mulvey won the series that year, and after winning the series, TDP sponsored him and built his car for the following year (purple 200sx)

In the 2004 season, it moved away from Rosegreen for the first time. First round was in watergrasshill, then Rosegreen, then Mondello, then rosegreen, and finished in Watergrasshill.

I know someone has above that Mike dean won it in 2004, but i could have sworn that Mulvey won it in 2004 again... could be wrong.

My engine blew half way through the 2004 season and my funds ran out so after 2004 i didn't follow it as much. But at least there is 2 years info for you anyway. :P
