A challenging one at race three but should take less than 5 tries, the controls are VERY touchy play with whatever is more comfortable for you, the stick or the pad.
You don't NEED the wrenches but it can help to make your car keep up just the little bit. I won two to three times over 10 races without wrenches Starting with the Right and bottom right most tracks, which I recommend using.
Much like super off road focus on just staying straight as possible and learn the courses every race won will put you ahead 3 tracks from the original track chosen. If you find it easier you may want to find the track that works best for you for your third race and just play under that pretense, this may involve you starting on the left side so you can end at the bottom right, play how you are comfortable and this will come in a few tries.
