Yes the seats from a Porsche will fit in an Audi TT.
However there may be some slight differences in the measurements since the two cars are not made by the same manufacturer.
If you’re looking to buy new seats for your Audi TT it’s best to consult with a specialist who can help you find seats that will be a perfect fit.
There are a few different ways to answer this question.
The first would be to consider the dimensions of the seats – height width and depth.
The second would be to look at the specifications of each car to see if they match.
Generally speaking Porsche seats are a bit narrower than Audi TT seats but they are about the same in terms of height and depth.
So in most cases they should fit just fine.
However it’s always best to check with a dealership or mechanic before making any assumptions.
