The Cobra Sebring T Pro-Fit GT in fibreglass, homologated to FIA 8855-1999. Part number COBSEBT-PF-GT.
GT means the wider shell
GT adds 30mm across the shell. That is the whole difference from the standard Sebring T Pro-Fit: same construction, same approval, same height, 30mm more width.
So this is the one to take if you have found competition seats tight through the hips and ribs, or if you wear a substantial suit and underwear layer and want the shell to still hold you rather than compress you.
If you are unsure which width you are, tell us your waist and chest over the kit you actually race in, not over a shirt.
The rest of the Sebring case
Built on Cobra’s closed moulding system, which makes the shell very rigid and the lightest in its class. The shoulders and head restraint are engineered for drivers up to 190cm, with the shoulder, head restraint and harness slot geometry held correct so a HANS device works as intended.
935mm tall, 690mm deep on a 500mm base.
Sizing beyond the shell width
The base and knee cushion comes in LO, MID and HI depths and the backrest in LO and MID, which with the two shell widths gives 36 combinations. Choose them at order from the dropdown.
Start at MID, MID, MID unless you know otherwise. Cushions can be changed later once you have driven in the seat.
What is built into the shell
High sided lateral and kidney support, and integrated head side support with shock absorbing foam. A two stage leg cushion for comfort over a long stint. Harness facility for 4, 5 and 6 point belts.
High tensile mounting bolts are supplied with the seat, which is worth knowing because they are the fastening that matters most and the one people are tempted to substitute.
Side mount. Seat only.
Have you written anything about this exact product?
Yes, we have covered this exact product: Does the Cobra Monaco Pro Fit My Mazda RX7 Mk3? A Detailed Fitment Guide, and Our Cobra Pro-Fit Bucket Seat 2023 Collection. That is first-hand coverage from our own builds and showroom, not brochure copy.
Will I fit in this seat?
The maker sizes this seat for drivers over 6ft in height with a 32in to 36in waist. Those are the paper numbers; how a seat actually feels to sit in and climb out of is a different question, and our showroom team sit in these seats every day, so call us with your height and waist and we will give you the honest answer.
Is it FIA approved, and for how long?
Yes, it carries FIA 8855-1999 homologation. Every FIA seat has a not-valid-after year printed on its homologation label, and that label date is what a scrutineer checks, so look at the label on the seat you receive and check it against your championship regulations. Buying new means you get the freshest label the maker currently produces.
What do I need to fit it to my car?
This is a side-mount seat: it hangs between side brackets, the motorsport-style stack with fine height and angle control. You will need the car-specific frame, and a sliding runner if you want fore-and-aft adjustment. Our guide on base mount versus side mount walks through the whole stack, and tell us your car and we will quote the full kit.
Does it work with harnesses and a HANS device?
The shell takes 4 point compatible and 6 point compatible. If you are planning the full seat, harness, and HANS setup, tell us the car and we will spec it end to end.
How do I know it will feel right, not just fit on paper?
Fair question, because makers publish widths and weights, never feel, and two seats with identical numbers can feel nothing alike in the car. We keep the ranges on display in the Nottingham showroom, you are welcome to come and sit in them, and if you cannot get to us, call and describe your build, as the team sit in these seats every day. Our head support measurements guide shows the kind of real-world data we collect.
