I'm considering buying this car. My goal is to use it for track days and also for driving/racing school to get my racing license and possible running it in some wheel to wheel 944 races. I've been through a few 944's and raced a few times already, but no spec ones yet, so any advice would be appreciated. I am a bit confused about the 944-spec vs spec-944 series? Like for example it sounds like on one race series you can use the fuchs, modified intake and some other extra stuff but in the other series, no fuchs and somewhat more stringent rules. 
The engine was recently rebuilt - the guys told me only 200 miles on the rebuild and no leaks or problems. The car was involved in an on track incident a few year back but was fixed. 
Here are the specs on the car that i'm looking at:
*1983 Porsche 944 Race Car for sale with rebuilt and tuned 1985 engine
*2 sets of Fuchs wheels. 1st set with Toyo R1 DOT R-compound tires. 
*Kirkey Race Seat. 
*AutoPower Roll Cage. 
*Adjustable Camber Plates. 
*Hypercoil 450 pound springs
*Koni Sport Adjustable Shocks/Struts
