car rack for multiple carbon bikes

[Nikul]

I need a car rack to safely transport ideally 4 full carbon bikes, including forks (if that cannot be done as many up to 4 as possible), the car is a vauxhall corsa (so a hatchback) and the journey will involve a long distance on the motorway.
Please help!

I would look at sea sucker products.

The sea sucker bomber 3 will do three bikes

And then mount the final bike on the hatchwith a seasucker hornet
