To answer your question, "Is it ok to run a Sportmax GP front and a D208GP rear?"
Yes, its fine.
I don't believe Dunlop makes the 208 or the 209 anymore. If you get these they are likely left overs. You can tell by looking at the date code on the tire (e.g. [04/05] = fourth week in 2005, [34/04] thirty-fourth week in 2004).
I am not exactly sure, but I believe the 208's were made in 2004 - 2005, the 209's made in 2006 - 2007, the 211's are new for 2008.
As long as the older tires were stored properly they should be fine to run.
For track day guys in the slower to mid group, the US made Dunlop is acceptable. For those that race or are fast in the advance trackday group, then I would steer clear of the US made Dunlops.
Personally, I would recommend trying to get a set of D209's (UK made) in medium compound. They last like iron and stick like glue).
