Portland international Raceway
 

PIR has a lot of days for porshes and audi's and bmw's but do they any days for the better cars like us?

They will usually let any makes of cars run with their group. Those are just the group/club names that actually rent the track for the day. If they have extras available they'll let ya run if you pay the fees they require, and your car passes tech inspection. You should be able to contact PIR and get the names of the clubs for the days you're interested, then contact the club directly for more info on pricing/availablility/stipulations etc..
