Traction do the AD08's in 255/40 R17 for $380ea. The RS3's are cheaper from RTR, but not by a whole lot, not sure they will last as long as the AD08's is the main thing. If they are 1-2 seconds quicker and last less, it maybe worth it. Maybe.
12-13 Track days and counting now on the AD08's, times are still coming down as the power and aero goes on.
Just for comparison, 1.50.x was my time at PI 3-4 events in a row with AD08's.
Drop a wing on the back, came down to a single 49 that next event.
Drop 40kw into the car, came down to consistent 49's lap after lap each session (then rain).
Drop an extra 30kw into the car, have to see on the 21st.
Where did 70kw come from....850cc, E85, Z32.
ARTZ the helmet needs the Aus Standards sticker, doesn't matter what type. It's in the sup regs on the rex entry page.
