Custom modified shape piston and lightened

We only use arc quality parts 

we start out with brand new pistion
 shape it for low drag coupled with low drag rings gives you the edge that  one sees coming 

I do not advertise the shape as each one is hand shaped may not be beautiful but I’ve seen results enough to offer it 

Be helpful if specs of motor are provided
