[Honda-C70] Grooved Drum Brake Shoes versus non-grooved drum brake shoes

 

Been looking to replace my brake shoes and noticed that there are two kinds offered by the good Dr.

Ones with grooves manufactured into them

And ones without.

The price difference isn't very much and I haven't found much information on grooved drum brake shoes. The most I found is that people say it's a sign of wear or breakage in the drum brake - obviously not the answer I'm looking for since the grooves are manufactured into the shoe, so they must be talking about if grooves appear on otherwise groove-less shoes.

So why are there grooves in some drum brake shoes over others? Is there some advantage to this? I've just upped my engine to a Honda clone and would like as much front braking power as possible - well at least much more than I have now.

Thanks
