I have the Kumho Ecsta SPT's on the back of the Aero and I am quite happy with them. No slipping and sliding for me. I dont push them real hard in normal driving but have been using them at the track and on a well prep'ed tack got a 1.7 sec 60' time, others in the 1.8 - 2.0 range. I will be using M/T ET Street drag radials next time out(if they get there in time).
