As above, I cant decide which to get! I will only use them for road use so I know both are overkill but is there any differences apart from the ultimax being quieter?
I am planning to pair them with yellow stuff or Axxis Ult if they come back in stock (hopefully a few weeks according to five speed).
If you go here, you can have the discs and pads Tuesday. If you want the Ultimax, they cost the same as the Turbo groove, so just say if that is what you would like.
If you want looks, then the grooved discs do nook good. Do they offer any more braking performance, probably not. I have certainly never noticed the Turbo Groove ones being noisy either, but then these are not quiet cars.
Brake pad choice is down to how you use your car. Brake effectively turn the kinetic energy of the car into heat via friction to give the retardation. The more you brake and the more frequently you brake, especially if you are braking aggressively due to driving, then the more energy you need to dissipate and the more heat is produced. OEM and equivalent pads are “soft” which give good initial bite in all sorts of conditions, however the softness acts against them under repeated hard braking as the temperatures rise, the friction ability can drop off as the face of the pad is cooked and breaks up. More “sporty” pads will cope with temperature far better, but do cost a fair bit more than “standard” pads.
There are pads that produce lower dust amounts, however they tend to be very hard and as a result, while they do offer braking performance, under repeated hard use they induce more heat and thermal stress into the braking system and you can get to the point where you boil the brake fluid. Ultimately something has to give.
Discs will rust. Just consider the environment they are in, and they are cast iron. Some people paint the cylindrical diameter, but you must be very careful not to get paint on to the hub face. However, if you use brakes hard, you will be taking the disc to very high temperatures and as a result paint and coatings have a hard job as well as being exposed to all the road contaminants and salts. However just the elevated temperatures are enough to cause oxidation of ferrous materials.
I have the MTEC grooved and drilled discs on my Alfa and they are a lot better than stock for 3 reasons one they are a lot better in the wet than stock also I have had very little if any brake fade and I am very hard on my brakes! also they haven’t gone horrible and rusty even after 3 years but that’s because of the hard baked on coating that didn’t burn off even after turning the disk blue once! also they lasted a lot longer than the stock ones did (1 year from new until worn away!) It took 3 years before I warped the MTEC ones though they were starting to get worn as the grooved were getting shallow
I had the Mintex pads that came with the discs and true story but they were only half worn after 3 years and about 30k and I use them hard and still had good braking TBH I was quite shocked and looking at the rears they look new…
Just in case anyone was confused about this, the noise was not intrusive, just something unusual after the standard discs, it only really became noticeable where the noise was confined by the surrounding structure, walled or banked roads where the “swish” became apparent.
The standard Mazda pads seem fine for normal road use and the odd bit of track use, as that is all my car does I feel the dustless pads are sufficient for me.
I do wonder whether Mazda UK has changed it’s pad supplier, certainly the set I’m currently using at the front show quite heavy dusting which was not evident on my previous set, to be fair I’m using the brakes more this year than last.
Thanks Kev, figure as they need doing and I can have a heavy right foot at the weekend upgrading them is the way forward.
I found the standard discs/pads experience a lot of fade when pushed. Often I drive from Manchester to Sheffield and Snakes Pass can ask a lot of them. Especially on the drop down into Glossop.
Decisions, decisions. Maybe I’ll go MTEC and we can do a compare/contrast time test!
I was advised that uprating the discs is largely pointless for performance vs price, though I do have a 2.5 Sport so have the bigger discs anyway.
I’ve gone for EBC Yellow Stuff pads though, apparently they bite well from cold and will suit my intended use of mainly fast road with an occasional track day. I’m not too concerned about the dust issue though, I’d prefer my car to look a bit scruffy on the road than have shiny wheels in a hedge!
