Nice shocks are expensive. There is a set on ebay right now for RB6.6. You should just buy a used RB6. I've seen lots of them with all the alloy upgrade parts for a reasonable price.

My YZ2 is in a league of its own I guess. As you can see from my user name, I'm a Kyosho guy. My first race car being a Ultima EP Type R and have had almost every K car and boat since.

Currently waiting on a few more titanium goodies to come in but this is my RB6.6 as it sits.

3 Gear lay down transmission
Titanium screws
5mm front and rear Carbon Fiber shock towers
Aluminum gunmetal wheel nuts
Aluminum front suspension block type B
Aluminum steering assembly with steering support UMW724
Aluminum rear 0 degree hubs
Aluminum battery post and thumb screws
Aluminum rear suspension holder
Yokomo spur gear cover(cause it looks great with all the other gunmetal lol)
Not to mention this was built with all aluminum washers not the plastic ones for more bling lol

One hella expensive roller here!







whats that slipper?

It is cool looking.
It looks heavier though.
I wonder if it keys onto the top shaft correctly or if it just "fits".
