I took it out to Johnson Valley this weekend and Holy crap is this thing bad ass. Crusing thru decent size whoops and sand washes at 50mph. My top speed on the lake bed was 77MPH at 9000RPM (red line). I weighed my car at 1620lbs with me and the wife in it. 65% rear 35% front. I changed my springs to 175lb front and 500lb rear and it was still a little to soft to jump.
