As stated before: Reducing rotating mass is critical in extracting performance from your Mini-Z. You will get an increase in response. Acceleration and deceleration is increased, and your batteries will last longer.
Reflex Racing always focus on the right stuff, and came out with a lightweight spur gear earlier on. See review here. The Reflex Racing 64 pitch machined Delrin Spur gear.
Now they have made a spur gear that is even lighter than the previous version. The V2!
It is a lot lighter than any other spur out there. It is also very durable since it is made from delrin.
You can choose to run with a bearing, or with the provided spacer. I always focus on reducing weight, so I opted for the spacer. With a bearing you can save some maintenance but at the cost of added weight.
The spur is a lot thinner than other spurs. This helps with friction as well.
Adjusting the diff tension with this gear is for some reason very sensitive. You have to adjust in very small increments, but by doing so you can achieve a perfect diff action.
It has space for 6 balls, witch also is a good thing, since 10 balls are to much, and 5 is sometimes to little. On our high grip track 10 balls are never necessary, and just adds weight to your drive train. 5 balls can be to little, and gives excessive slipping.
Since RR supplies this spur with two different spacers you will always find the correct spacing. One is fitted for almost all combos, and the other is quite thick so you can grind it down to match every combo out there.
Supplied in the kit are one 2mm spacer, and one 3,3mm spacer.
I mounted this with a PN alu diff shaft, and QteQ diff parts.
Compared to the old spur, this weighs 0,2 grams less. This sounds like very little, but I promise you. This will be noticed!
The accelleration and decelleration is improved!
You also get an ultra responsive car, since your throttle input are instant. You get a lot better feel for your car.
Combine this with PN Racing Ultra light alu diff shaft, and QteQ diff parts, you get the ultimate differential. This is actually lighter than the stock plastic diff!!!!!
5.0 grams! You cant beat that with any other combo!
