whats a good retainer? ive seen like 5 different type.

 

whats a good retainer for what application?? what is you trying to do with your engine? is it for daily driven or track only? we need engine specs, your goals, and what it is intended for? when you speak of types, are u referring to brands or materials? we need more info to help you.

 

Easy there, don't give us all your specs and use for the car all at once......
