First, decide what your goal is for your car.
Leather on base seats, although will look great, will be slippery in corners,
especially for right seat passenger, no matter who it is.
If building straight line rocket, not much of an issue.
If you want to fully exploit the handling pack on your car, keep the seats you have.
The fabric material keeps everyone planted in the seats much better.
Or do go up to the Recaros, leather or fabric.
On the Recaros, if you haven’t already, you should try to sit in them for a bit before pulling the trigger.
Some people find the bolstering a bit tight.
Sometimes, personal body type can influence decision.
With the intent of remaining objective here, often individuals of smaller stature fit better in the Recaros.
And individuals of heftier stature sometimes, not always, find them a bit tight or restrictive after a while.
