Roller weights from AliExpress

[Yoni159]

I saw 9gram rolles on AliExpress but does anyone know if they good? They without brand and they really cheap does anyone bought from AliExpress and can help me if they worth something...

Ali express is hit or miss...some stuff can be good, other stuff, junk. I would probably find a slightly higher quality source for my rollers as these are an important part of our drivetrain. If you decide to go with Aliexpress please let us know what you think of them.

What Hawk said. In spades. I’d pay the extra for this important component.

As written before: too light!
Weights are originally 15,4g 20x12 mm.
If you go to 9gr, you get a wailer unheard.

DT 300I 15.4 or .5 gm .. I know this because I weighed them!
      350i  13.0 gm  ..  I will wait for Ruffus' confirmation!

You are entirely encouraged to experiment all you want because that is the nature of hot-rodding in most of England, USA and Australia to name three. Cosworth of England to name just one, the great Cosworth-Ford soup-ups that went into the Lotus-America thing I drove ONCE in about '63 and scared the ***P outta me! USA full of hot-rodders like Edelbrock, Hedmann, Mickey Thompson, Iskenderian who are a few who made business of manufacturing "speed goodies" for us greasers to spend money!

Burt Munroe from either Australia or New Zealand, the reclusive genius who cast his own pistons by carefully sculpting the female form in the ground near his shop!

You may be next!
