BC Racing Coilovers Lexus Rc350 come as a matched four-corner kit cut to the correct damper lengths for the car. Chassis code GSC10. Fits 15+ cars. Default spring rates are front 9 kg/mm / rear 9 kg/mm.
Because height is adjusted at the lower bracket, dropping the car does not add spring preload. You keep the full damper stroke instead of running out of travel at the bottom.

Spring rates and what is in the box
This kit ships at 9 kg/mm front and 9 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 Lexus Rc350
Work on a flat floor, set the height on the lower brackets, then roll the car forward and back to settle everything before you take a final measurement. Alignment comes after the height is set, not before.
Start with the damping adjusters in the middle of their range and work from there. Wind towards firm for track work and back off for road use, changing one end of the car at a time so you can feel what each change did.
The kit is rebuildable and the springs are a standard ID, so a rate change later is a spring swap rather than a new set of coilovers.
Worth reading if you are new to this: how a coilover works and why height and preload are separate adjustments.
BC Racing Coilovers Lexus Rc350 questions
Will BC Racing Coilovers Lexus Rc350 fit without modification?
The kit is cut to the Lexus Rc350 damper and strut dimensions and uses the standard mounting points on the GSC10 chassis. No cutting or welding is needed for a standard car.
How low will the Lexus Rc350 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 Lexus Rc350 come with?
Front: 9 kg/mm / Rear: 9 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.
