Is it time to replace your race suit? Let’s get you track-ready. 
BC Racing Coilovers Seat Leon Strut replace the standard dampers and springs with an adjustable, rebuildable setup. Chassis code 1P. Fits 05-12 cars. Default spring rates are front 6 kg/mm / rear 6 kg/mm.
Height and preload are adjusted separately. Lowering the car on the bracket leaves the spring seat where it is, so you are not trading ride quality for ride height.

Spring rates and what is in the box
This kit ships at 6 kg/mm front and 6 kg/mm rear. The rates are matched front to rear for a balanced setup on the road. Rates are chosen by BC Racing per application, so they suit a fast road and occasional track car as supplied. If the car is built for something more specific, a track weapon or a car carrying a lot of aero, the rates can be changed without replacing the dampers.
The kit covers all four corners and includes the dampers, springs, lower brackets, locking collars and the adjuster spanners. Top mounts depend on the configuration you pick from the table above. Anything that is worn on the car already, drop links, bushes, top mount bearings, is worth checking while the suspension is apart.
Fitting and setting up BC Racing Coilovers Seat Leon Strut
Set corner heights on level ground with the driver weight accounted for, then roll the car and settle the suspension before measuring again. Ride height changes on the bracket, damping on the adjuster knob.
Middle of the range is the sensible starting point. Move a few clicks at a time and keep notes, because chasing damping settings from memory rarely ends well.
The dampers are rebuildable. When they eventually need attention they can be stripped and revalved instead of binned, and spring rates can be changed later without replacing the whole kit.
Worth reading if you are new to this: how a coilover works and why height and preload are separate adjustments.
BC Racing Coilovers Seat Leon Strut questions
Will BC Racing Coilovers Seat Leon Strut fit without modification?
The kit is cut to the Seat Leon (Strut 54.5mm) damper and strut dimensions and uses the standard mounting points on the 1P chassis. No cutting or welding is needed for a standard car.
How low will the Seat Leon (Strut 54.5mm) go on these?
Height is adjustable across the full range of the lower bracket. How low you can usefully run depends on your wheel and tyre size and how the car is used, so set it to suit how the car is actually used.
What spring rates do BC Racing Coilovers Seat Leon Strut come with?
Front: 6 kg/mm / Rear: 6 kg/mm as standard. The springs are a standard ID, so rates can be changed later without replacing the dampers.
Do I need an alignment afterwards?
Yes. Camber and toe both move as the car comes down, so book the alignment once the ride height is set and the suspension has settled.
Are these road legal?
Adjustable suspension is legal for road use in the UK. Keep the ride height sensible, make sure nothing fouls at full lock or full compression, and tell your insurer the car has been modified.
