I have been offered a full 10 pot tarox brake kit over here in France for 750 euros. Just wondering if there worth fitting . I am currently running 4 pot fronts and 2 pot rears with grooved discs.

 

Yes they are but depends whats inluded in a price.
Check new discs prices,some are very expensive.
Put braided brake lines and pagid rst3 pads.

 

It comes with front and rear discs in good condition but pads need changing. I already have brake lines. Do you think I will need a bigger master cylinder ?

 

Some pictures

 

wrx master cylinder is ok ,check piston seals if are ok and pistons for rust

 

Have they literally just come off a car in use or have they been removed and sitting around for some time?

If the latter, I would advise stripping them and inspecting seals/pistons/nipples etc and replacing where required, before fitting them.

Obviously also make sure that they fit behind your wheels
