In reality you get a bit more from the WMS calipers as they work better
![](./images/smilies/spacer.gif)
(less losses in pad clip and slider friction).
![](./images/smilies/spacer.gif)
As for fade, the 298.5x18 WMS seems to match or slightly beat the Rev 2 OEM with the same pad compound
![](./images/smilies/spacer.gif)
(I swapped the two setups over a few times on my car)
![](./images/smilies/spacer.gif)
- the WMS disc is lighter but bigger=better cooling.
![](./images/smilies/spacer.gif)
The 280mm ones will have similar cooling to the Rev 2 disc, but less thermal mass
![](./images/smilies/spacer.gif)
(the 280x28mm one isn't too much different to Rev 2 though), but the pads get an easier life in a 4-pot caliper, plus the caliper cools faster being aluminium which conducts heat away from the pads faster.

So hard to call on the fade one other than
![](./images/smilies/spacer.gif)
"very similar"
![](./images/smilies/spacer.gif)
- but remember you can get better pads for your money with a WMS caliper, so the

"
fade resistance per
£ spent on pads![](./images/smilies/spacer.gif)
" will be better than OEM for sure and this is what matters at the end of the day for most people
![](./images/smilies/spacer.gif)
- the performance they get for their money.
