Not worth it unless you are desparate for every 1/2 hp gain you can get! That makes sense I suppose. I bet you're still going for it in your project then OG!

I have to now .

The odd saving here and there isn't worth it. However, a little saved in a LOT of places adds up. I reckon I will have removed over 100kg from a 750kg car by the time I have finished which equates to over 4/10ths over the 1/4 mile.
