Where can I find instructions for the installing the pro kingpin front suspension?

Edit: Nevermind figured it out. Needed to ream the white inserts now it’s smooth.

I’ve been using the awesomatix a12 steering bushings in my F1. I’ve got the new ones on the way. Is there an on track difference between them?

The new bushing have more surface area, so you have to use a thinner kingpin grease. Moving from 15k down to 5k with the new bushing is typical.

Yeah, we need Josh to develop new greases in 4,5 and 6K... Sure, there's silicone oil, but its messier and I like the convenience of the grease. One more thing to put on the wish list!

I already have a test version of 5k and 10k to test. Kyosho also makes a 1k, 3k and 5k. The 5k Kyosho works, but the guys are saying it doesn't stay on as long as the new test stuff.

The new inserts actually go all the way through to those interlocking teeth. There is more surface area and more grooves to hold the fluid. They also kind of click in so there is no slop whatsoever. Another cool design from Josh. Get a good 5.1mm reamer though and make sure that you've done a thorough job with it. I heard someone else say that a 5.2mm reamer would allow the use of 15ks like we have been using. I'm not sure where to get a 5.2mm reamer?

The only issue with using the A12 bushings is that they are a little bigger and far less surface area so you really have to use a 30k to get the same feeling as the 15k.

New asphalt F1 Tires are now available on the site. Two compounds each for front and rear.

How do these compare to the current tires?

They are harder - made for asphalt. Inspired by the drag race compounds they've had for a couple of years.

Just to be clear, the soft asphalt is a different compound than the soft carpet set?

Yes sir. The current carpet tires CS - Carpet Soft for rears and CM - Carpet Medium for fronts are still on the site as well. No color dots on the sides of the carpet tires currently.

I’m using the kyosho blue 30k grease for the a12 bushings right now. I’ve been told it’s better for me to use the kyosho yellow 15k grease instead when I get the new steering bushings as it will feel similar to the 30k.

on another subject is there a chart that shows the hardness of all available front springs that fit on the prodigy lineup?

Heck yeah! I'll be running these in Memphis starting in the spring. Looking forward to not having to run foams outside!

[QUOTE=Kruss45;16228111]I did this using a drill press and scale, measuring each spring to the middle of it's compression length. This shows pressure at the mid point, but will not give any insights into progressive vs linear springs.

I had a chance to run these a little while back. Absolutely loved them, wear seems to be great. Obviously the different compounds are nice to have for track conditions and setup. I liked the yellow rears, and purple fronts on my Prodigy. Ran them with a ball diff on a medium to high grip asphalt track ( Jackson ).

New on the site today, lighter damping grease, 5k and 10k.
