VmanC, what did you do to your brakes? what upgrades?
Not done yet but the plan is to upgrade to Selecta discs and calipers. I've got this in mind for two Panda's I'm currently fitting bigger engines to, one will have a Punto 75 unit, the other a 1242 16v. Neither engine will produce more than 100bhp so I think the Selecta brakes should be sufficient, plus I still have the option of 13" wheels.
Selecta calipers are thin on the ground, I only have one pair, but I've noticed that the Punto 75 uses the same piston assembly. The caliper is made up of two main parts that slide together and although the part with the piston is the same the other part which bolts to the hub is different. The two bolt spacing on the Selecta is spot on for the Panda of course, but on the Punto they are closer together. I'm hoping to re-drill the holes in the hub backplate on one of the Pandas to allow fitment of the complete Punto assembly.
I haven't checked the possible use of the 16v Puntos calipers yet, but this too may be an option. Will let you know once I've reached this stage.
I'm not too bothered about the rear brakes as they don't contribute a great deal overall, but if these initial improvements aren't sufficient I will be looking to take things further.
I know that if you increase the size of the brakes too much you then need to look for a master cylinder that can displace more fluid, so keeping the mods as moderate as possible, but good enough, may save this hassle.
