thanks for the pic and info.. great work..
I know the section of road you are talking about (on-ramp roundabout to Ipswich Hwy --- down hill 270 degree left turn). It is always very exciting when driving that section... I also enjoy the roundabout linking Ipswich hwy to Centenary hwy. (west bound then north bound). it is a good section to test out the limit of the tyres and suspansions.
