Which base do i need?

This is quite difficult to answer. Since we do not know your needs yet it is kind of impossible to say which Wheel Base would be best suited for you.

To create personalized recommendations based on your specific needs, several factors are relevant:

• Which platform(s) will you be racing on? (Xbox, PlayStation, Windows PC)

• Which types of cars do you see yourself racing? (F1, GT, Rally)

• What types of games do you intend to play?

• Do you have a preferred budget range you would like to stay within?

• Will you be mounting your setup with a rig/cockpit, or will you mount it on a desk/table?

• Will you be playing for fun, or competitively?

We recommend contacting our product consultation team via the related contact form for personalized suggestions.
Meanwhile, I'll continue to learn more each day and hope to soon be able to provide such responses myself!

Feel free to give me another chance with more details within the question :-)
Thank you!
