Steel or bronze?

Pro's and cons of each?

2wd sapphy not running too mad, just stage 1 but wanna go stage 3 end of the year.

 

They're bronze as standard aint they?????

 

I have no i

Personally i would of thought steel would of lasted longer than bronze but is there any downside?

 

The oe amterial was a mix of several different things.
Bronze is good, but COLSHIBO is better, and what I use, the person I use makes(machines) these themselves, and have done over 3000 with not one problem, even on £100,000 + engines for competition.

Funny way to spell chocolate though mate

 

i had bronze ones in mine, thats just what the engine builder got for it, kent ones i think they were.

 

I think the oe ones were a sintered metal mix, probably crushed iron, but not sure.
