The Sparco Ultra QRT is a minimalist fiberglass-composite seat for an owner who wants a bare-shell driving position. A shaped lumbar area and recline are built into the shell instead of a thick upholstered cushion.

Selection and Installation
The QRT shell offers the same bare-seat concept in fiberglass composite. Assess comfort with the padding configuration you will actually use: adding a pad can change helmet height and support relative to the steering wheel.
