can someone please advise if they consider these a massive/good/slight improvement if upgraded

or standard brembo + pf discs better than AP 4 pots

input welcome

 

Ap racing 4/6pots alot better than brembos I recommend ap racing, alcon brakes

 

to a degree it depends on which AP 4pot your talking about.............

the cp6600 style are similiar to Brembo's IMO, whilst the cp5200/5040 generally perform better

 

If your using the same type of pad , and a good disc , there wouldn't be much in it between the AP 4 pots or Brembo STi 4 pots , its not something I would tell a customer to spend the extra on , it would probably cost around a grand to change taking into account selling the STi brembo set up , I think it would be a waste of money
its basic physic's really , both are 4 pot calipers , both run about the same size disc , and the pads are similar size , so how can one be better than the other , the only advantage you would get running the AP 4 pots would be that they are lighter , so if your building a race or track day and are keeping the weight down , the AP's are the ones to go for
I would recommend the AP 6 pots over the Brembo STi calipers as you would get a noticable increase in braking power from high speed , the AP 6 pot has a larger pad than the 4 pot caliper

what would cp7040 6 pot cost me brand new?

proper ap kit not cheap reyland kit

 

The AP kits using the 7040 calipers are either 355mm or 362mm so will only fit under 18" wheels , these kits are £1995.

We also make kits up using 7040 calipers but with our own discs bells and brackets , and a choice of pads , but we can offer a 335mm kit to fit under 17" wheels , as well as a 355mm kit for 18's.
Our kits are £1400 and £1500 respectively
