boxerparts oversize brake rotor for bmw r 100 gs

Does it make a good difference from the stock brake rotor and worth the extra money. Other alternative?

I had a 320 mm rotor on my G/S and it made a difference in braking power.

If you want another option you could change the caliper to a four pot Brembo and buy one that has been modified (.0158" off the tabs), or have it done. There is a six pot conversion but you need a small bracket made.

My question to you on the over sized rotor is when it needs to be replaced can you buy the rotor by itself? If not then that's gonna be expensive. Then if you can by the rotor by itself how much is it.

The four pot Brembo is cheaper and uses stock easily obtainable pads.

Yes, you can do. Boxerparts is selling only the rotor with the adaptor but it is not cheap. 225 Euro plus shipping cost in north america, 45 euro.
Want to make a modification with a four pot brembo caliper as you suggest with a galfer ss braided line and green pads. Not too expensive, but questionning if the change of the rotor worth the money for the improvement it gives.

Yes the 320mm kit is a substantial improvement over the stock item, the whole kit is cheaper than the original disc and you can buy the disc on it's own from HE themselves, somewhere in the region of 150 euros.

The cheapest place is Motoren Israel because of the way they exchange/charge the money, no surcharges for currency exchange and card use. The devil is in the detail! DAMHIK

Edit: Yeah, what he said while I was typing.

You can get a modified caliper, but with this combination you can instead take 4mm off the hub spacer you get with the 320mm conversion kit, that way you can leave the caliper stock and move the disc 4mm more inboard.



The pictured brake disc is a replacement, it was specially manufactured for me by the guy from http://www.mx-tec.eu. Still not dead cheap, but my first one was good for 50k miles and got replaced not because it got too thin but because the aluminium floaters were worn out and having a few mm radial play in your brakes is kinda unsettling. This version has stainless floaters, so should be good for a while to come.

if you plan on doing the four pot conversion anyway....do it 1st and see if your happy with the brakes. I think you will be. Then no need for the larger rotor.
