The “Megane” calipers are slightly larger from the outside than “Clio” (they’re 5mm wider per side, that’s quite important If your are using OEM wheels or high ET wheels as they require +5mm more wheel spacers compared to “Clio”). The “Megane” calipers use a little larger brake pads – 131x75mm vs 125×70.7 in “Clio”.
The pistons size is the same in both caliper models.
There is also a weight difference:
1) Clio: 2366g
2) Megane: 2716g
For performance issues the “Megane” calipers setup should handle a little more abuse when used in endurance races due to better heat dissipation but the “Clio” calipers also perform really well in lighter cars like Civic EP3, Mazda MX-5, Toyota GT86 etc.
