10/10ths Motorsports at Putnam Park. Car was oversteering badly as I changed out my front springs from 1000/600 to 800/600. As well, I thought it was going to rain all weekend so I was running my street tires - Goodyear F1GS3s.
UPDATE - No wonder the car was so loose, I found out later when I got home that one of the front sway bar links had snapped. So I was actually running with no front sway bar and a big ass 22mm sway in the rear.
