See this asked here and there and it was questioned on the french forum a renault guy confirmed: Is there another way "visual" to identify a cup Chassis? I want to say one other detail that the disks grooves + Callipers red in color. The dampers have the color codes for the cup chassis must be lower under the car and watch the front spring: blue purple green dots and on the rears 2 yellow dots
To be honest, I wouldn't know a non cup from a cup if it passed me on the road. I just remember the plate and bung it into webuyanycar
unless you have a full fat 250/265 with cup chassis, that wont show up! point I was actually making was those people who buy a car and are like 'is mine a cup?' 'do I have a cup chassis' you can now be sure by looking at the dots on the springs
Full fat cars have the cup chassis as an add on so on vehicle checks show up as renaultsport 250/265 (coupe) only on factory cup cars show up as Renault 250/265 cup (coupe).
