For those doing the 288mm to 312mm rotor and caliper mount swap, I’m assuming you need to buy the caliper mount bolts for the 312mm and cannot re-use your existing ones?
You can re-use them. Mounting bracket bolts should have loctite on them, too.
Thanks, any idea why the caliper mount bolts for the 288mm brakes have a different part number than the 312mm?
If I’m not changing the hub, do I need different size bolts?
I guess what I’m asking is are different size caliper mount bolts needed for the 312mm upgrade?
Awesome, thanks guys. Can’t wait to do this mod. Scored some used calipers/mounts/pads on eBay for $70 shipped (both sides).
If I install these used calipers which already have mounts and pads will I get a brake pad warning light?
Did this upgrade two weeks ago. The brakes feel exactly the same as before. No better, no worse. Even the pedal feel is virtually the same. These brakes work way better in my TTRS. I wonder if it’s because that car is so much lighter than my wagon or if it’s because of the different master cylinder?
The TRW specs show the same for the Golf vs GTI/PP/R master cylinder (despite the different VAG part numbers, if I remember correctly the GTI part number ends in "B") but they are in fact different, as is the brake booster. I have upgraded brakes on my Golf TDI and bought the GTI master cylinder to have installed at the same time thinking it would be a direct swap, it was not.Very strange......
…..the 288mm setup & master cylinder is the same as the 312mm GTI/GTD setup only difference is the carrier & the disc ….& I felt a much more linear response afterwards as the 288mm setup was grabby...

I'm only talking NAR, haven't looked up any part numbers for ROW. But the gulf has a different set up from it's faster brethren, which all share the same part number. As I recall the GTI/PP/R share the same part numbers as the S3 as well.
