A genuine Brembo 332mm cross-drilled replacement rotor, 32mm thick, for a Brembo Gran Turismo big brake system as fitted to the Mercedes Slk-class (R170).
This is the iron rotor ring on its own. It bolts to the aluminium bell already on the car, so the bell and its bobbins are not included. If your bobbins are worn, order a bobbin kit at the same time.

This rotor is handed, so the left and right parts are different. Tell us which side you need, or order two and we will send a matched pair.
Price shown is for one rotor.
Brembo recommends replacing discs in axle pairs and fitting new pads at the same time. Brake work is safety critical, so use a qualified technician and bed the discs in to the instructions supplied.
Will it fit my car?
This kit is built for the car named in the listing, and the generation matters: hub design, hub bell shape, and caliper bracketry are car-specific even when the disc size looks the same. If your car is near a facelift year or an unusual variant, send us the registration and we will confirm the exact kit before you order.
Will it clear my wheels?
Minimum wheel diameter depends on the kit, and spoke depth on your specific wheels decides real clearance at that diameter. Tell us the kit and your wheel model, ideally with a photo, and we will confirm the fit before you order.
Which pad compound should I run?
It depends on use, not on the kit: fast road, track day, and race compounds behave very differently when cold and when worked hard. Our guide on brake pad compounds explains the choices for these kits in plain terms, and heading to a circuit, our track day brake prep guide covers pads, fluid, and bedding in.
Every brake kit here is built to order
We do not keep big brake kits on a shelf. Each one is put together for your car in the disc face, caliper colour and specification you choose when you order, so nothing is made until the order is placed. The site shows these as available because we can take the order and start it, not because it is boxed and waiting.
How long it takes
Brembo GT kits are made in Italy and run around six to eight weeks. Our UK built kits are quicker, and the exact time depends on the caliper and disc combination you pick. Ring us on 0115 989 3488 before you order and we will give you the current lead time for the kit you are looking at, not a general one.
Working to a date
If the car is booked in, or it is off the road, tell us the date when you call. We will tell you straight whether the kit will make it, and what the alternatives are if it will not.
Worth two minutes before you order
Wheel clearance catches people out. Send us your wheel make, size and offset and we will read it against the caliper clearance drawing first, because a kit that is already being built for you is not something we can simply swap.
