Review: These seem like a decent value. - These brass weights seem solid for the money. Mine came in old looking packaging that was yellowed and gross looking, but I’m not sure if that’s from age, or the material itself. I had some brass dust on the parts themselves, but that wiped off and the actual machining looks ok. For $25, I’d say they are a solid performance upgrade. They are very heavy, and are pretty much as low as you could get. They even fit behind my SSD wheels, I’ll be it, it’s tight. I would recommend these at $25.
Review: Perfect fit - They're exactly what I wanted and they fit perfectly fine and they're actually was two leftover screws which was cool I'll buy from them again and now I'm set because the original truck weight is 5.79 lb and now I'm above six almost seven I think.

## Questions & Answers

**Q: Are these 76g a piece? I see someone posted they are only about 19g**
A: Jason C is wrong.  They are 76g/pc.  Mine were actually 74g/pc, but close enough

**Q: Do you recommend doing all four wheels or just the front?**
A: You want to lower truck and everything you can then add weight if need be. Rule of thumb is 60%Front/40%Rear weight biases

**Q: Estas piezas son para la parte delantera o tracera del Trx4?**
A: Son para las cuatro ruedas

**Q: do I need hub extensions?**
A: No they slide over your wheel hubs. Perfect fit. I love them. Has a nice added weight to the truck

### ⭐⭐⭐⭐⭐ Heavy.
*by K***E on March 25, 2024*

They are dense and heavy, extremely clean machining. The price to quality ratio is very good. Fit right on, I got the correct screws, and made a noticeable performance difference. Don’t really see how people can leave a one star review crying, even if they did get the wrong screw. For the price, I wasn’t even expecting to get hardware. It was just a nice bonus
