So deep shall my tt be!

Hello, I would like to reach the deep of the tt ́s on the photo. also with 19″ rims. is a ttc 180 front. rich there springs? or would you rather winch the same? how are these fk winches? the costs only about 500eur! do you happen to have photos of your tt ́s with 19″ and suspension? maybe you can write what you have built in.
