There's a small ramp facing towards a house north of the hotel just north of the lake. Use the ramp to jump over the house for the great performance. I kind of forgot where the house is exactly, but maybe someone else can help. You can see the ramp in I think the fourth level of the rally car racing mode of off road racing.
at the moment i have 9 gold keys, but at the mountain resort. I am missing 2 great performances. I already have jumping at the houses outside the tunnel, and jumping over the house near Otti Mcrae station. Could someone tell me how i can get the other 2.?
1. Jump on top of the ferry going around Trumela Lake (the lake you start out next to). Go to the back of the castle and jump off into the series of islands, when you get to the last one, wait there for the ship to past underneath and jump ON TOP of it.
2. Just outside the ruins, you should see a very steep rock wall with lots of bumps. Use an off road car to drive up the steep slope.
