Our recommendationMatch the frame to the seat brand
With six frames on offer and Corbeau and Recaro locked to their own seats, the choice comes down to which brand of seat you want. Cameron works out the fit and the best combination for a given car, so tell him your build and he will narrow the list.
Harnesses
There is no harness made specifically for the Leon Mk3, so you are fitting a universal belt and working out the mounting yourself. The standard rear seat belt mounts are not rated for harness shoulder strap loads, so one of the cages below, a bolt-in harness bar, or a fabricated anchor point is needed.
The Schroth Profi 3×2 at £370.01 and the TRS Magnum 6 Point Superlite at £245.00 are both FIA 8853-2016. The TRS Magnum 4 Point at £205.00 is FIA 8854-1998. All three carry a stamped expiry date regardless of wear. For a road or trackday car, the Takata Drift II and III and the TRS Clubman belts cost less, though none of those four are HANS compatible.

Our recommendationConfirm the anchor before the belt
Tell us whether the car is caged, what is behind the seats now, and whether a head restraint is going in, and we will tell you what the shoulder straps can anchor to before you spend anything on the belt.
Roll cages
JP Cages split their range by body style. For the 3-door: a DIY Half Cage at £295.62, a Half Cage at £461, and a Multipoint Dash Dodger at £727.65. For the 5-door: a DIY Half Cage at £295.62, a Half Cage at £461, and a full Competition Cage at £791.75, the most thorough option on this page. Confirm which body your Leon is before ordering.
If competing, check the specification against your class regulations before ordering, and keep the sign-off paperwork with the logbook. Pad any tube within reach of a helmet, and tell your insurer, because a cage is a notifiable modification.

Common questions
Which frame does the Leon Mk3 (5F) need?
Six are confirmed: M2 at £138.50, Sparco at £78.00 OMP at £106.37, Planted at £187.46, Corbeau at £289.50 for Corbeau seats, and Recaro at £414.75 for Recaro seats.
Does the Recaro frame fit any other car?
Yes. It is listed as fitting the Leon Mk3, VW Golf Mk7 and Skoda Octavia Mk3 together, since all three share the MQB platform floor.
Does the same cage fit the 3-door and 5-door Leon?
Not always. JP Cages split several of their listings by body style, so confirm whether your Leon is a 3-door or 5-door before ordering.
Which cage should I choose?
It depends on body style and budget. The DIY Half Cage at £295.62 suits either body on a budget build, while the 5-door Competition Cage at £791.75 is the fullest option on this page.
Can I use the standard rear seat belt mounts for a harness?
No. They are not rated for the loads a harness shoulder strap puts through them in an impact. One of the cages above, a bolt-in harness bar, or a fabricated anchor point is needed instead.

What's the best FIA bucket seat for a Seat Leon Mk3 (5F)?
The Cobra Monaco Pro at £235 is the cheapest FIA shell for the Leon Mk3, and a sensible start if this is your first bucket seat. Step up through the OMP Champ-R, Mirco RTS-2 3D or Sparco Grid Q in the mid-range, or go for the Corbeau Pro Series X System 1, OMP RT Carbon/Fibreglass or Recaro Pole Position with ABE at the top of the range if budget allows.
All of these fit on the frame that matches the seat, with a side mount added where the seat’s mounting column calls for one, so check which mount type your chosen seat needs before ordering.
