I lowered the suspension on mine, put in some stiffer front springs and "dialed in" the suspension in general. Added some Yokohama AO32R's and the difference in handling at the track was night and day!
Indeed the Excals CAN hustle around a track and do it quite nicely!
Later I raised the front end back to about 4 inches clearance from what had been about 3 inches. Handling was only marginally decreased, but "speed bumps" were much more friendly! Not to mention the improved ride quality!
