sorry... I want a XRT setup for SO1........The setup can used for 30minutes race...... anybody have it?

Try here or here.

You need to work on driving style.. pretty much any setup can last that time if you're careful on the tyres. Be careful and don't lock up or spin the wheels coming out of corners, and definatly don't get sideways!!

My friend here will already find many
