This reminds me. Is there a part number for the thicker RF2 plastic suspension block that comes with the kit? The one that comes with the UM508C tree is the older RF2 with the thin edges. Try putting one of those on and you will be replacing it every few races if your track has any sizable jumps at all. Kyosho must have found that out and beefed it up, but how do you buy it? Am I missing something?

I had to do some digging myself to figure it out - I remember that the RF2 block was the only piece from that tree that I used in the build.

Randy - I believe the part number you're looking for is UM726. It's specified as a mid-motor part, but the bubble callout 132 in the manual points to this number in the parts list rather than UM508C, which would be for the old thinner toe blocks. The image on the page should show you that the part you're looking for is on the right side of the tree.

So how many guys have moved from heavier full sized lipos, to lighter or shorty lipos? I have been running my Fantom 6500 65c Lipos in this car since day 1, and as fantastic as the car is, it just "felt" too heavy on the track.
This last weekend I decided to run shorties for the day, and MAN what a difference! I did some weighing, and with my 6500s, the car was 200 grams over weight with a full sized BLS351 servo. With the a shorty, I was only 100 grams over weight and it made all the difference in the world. Car was snappier, responded better in all regards (throttle, braking, and turning), and it made a noticeable difference in lap times, first time on the track. I ran the shorty dead smack in the middle of where the full sized pack sat to keep the F to R weight bias about the same... worked perfect.
I can't see me ever going back to a heavy ~300gram pack ever again in this car. Im going to stick with the ~200. Needless to say, I immediately put an order in for a pair of Fantom 4500 shorties. Can't wait to get more track time in the newer lighter set up. -YMMV

What is the difference between the blocks on the track?

So I just put the triad in my car. I run stock also so keep that in mind. I liked the overall feel of the slipper and it seemed to be much more consistent than the ae pads with spur gear I was using. I have yet to try it out in mod, but I think I will be doing that in the next couple of weeks.
Overall if the swap out was just simple kit without having to buy the new top shaft for the car, I would say definitely get it! But since you need to buy a new top shaft for it, it's somewhat questionable. Maybe I will notice more of a difference in modified when I start playing with it.
In regards to the pistons AVID makes I would have to say I like them quite a bit. Very smooth and when changing out between the the 4 hole 1.6 and 1.1 to the two hole 1.6 from the stock pistons it seemed to settle the car down quite a bit and actually seemed like it helped it to jump slighting better. I did manage to get a couple sub 21s in practice but in my qualifiers I was a little all over the place, as my concentration really wasn't there for some reason.

If I ran blinky 17.5 I'd tune for the shorty. For open I'd use full size stick for weight/traction.
