The company that makes these discs thoroughly recommends Ferodo pads. There are different grades from a standard OEM type through to race compounds, you probably want to start at the lower end as the sportier ones could still be quite sharp on initial braking.

Thanks Zep. I’ll probably try the OEM ferodo pads when I change the discs.

This is where it all gets a bit interesting. If you don’t change the master cylinder, you have to keep the same piston area in the caliper, or you have an issue with pedal travel, so the only benefit from a 8 pot caliper is increased pad area, not really something there is a massive issue with. To me, the difference to a German is pedal pressure, there is more servo assistance which gives the feel of more initial bite.

Almost anything is possible, 380mm is the limit for the standard caliper in terms of adaption, but with a different caliper 400mm would be possible, but would need a more complex mounting bracket and attention to wheel clearance and would probably be at least another £2k. But happy to do it if there is the appetite.
My rear discs and pads need replacing. What would you recommend? Will do fronts with your system when needed. Thanks

If you are happy with a slight mismatch between the pattern on the discs front to rear (most people are) then I would go for the pattern rear discs from Eurospares.

great thanks for your help. Would you recommend a different pad? I would like to improve the feel and consistency and whilst this may be affected by the front discs/pads etc I would welcome any suggestions for the rear too. Cheers

I really rate the Ferodo DS performance range. FDS1348 for the rear of a GTS. Burton Power are doing a good price, because they also fit the front brakes of a Ford Focus RS.
