Just clean them and then about 5 min before you hit the track, hit em with motorspray. Try it in practice once with, once without.

Thats why I use it. most of the time im running around helping guys out so I never get alot of time to prep my tires.. Doesnt seem to wear tires bad either.

How much longer till outdoor racing bob?

technically April 6th....but I mean they are calling for snow here this weekend so it may be just a tad bit longer haha

Jake, do you race anymore?

yeah havent had saturdays to come race where you do.

the 2 hole casters help that much to tighten it up?

they did for me, and i got 2 race days on them soo far and still tight. its because they are machined not molded, so the tolerances are alot tighter.

I used to use them on the original b4. But after I got my WC, I seemed to stock pipe the 3 holes. And they dont seem to break, lol. So i have like 3 pair. I do have some slop in the front casters. I might have a carbon 2 hole laying around, I will try to see if it tightens it up a little. If so, I might pick a set up. The buggy is like 6 months old now, so even though slop is not bad, there are limits, lol.

The 2 hole blocks are not machined, they are molded. They are just molded of a different/stiffer material.

Correct. The hole for the hinge pin is drilled in the 2 hole blocks vs molded into the 3 hole blocks.

^ what i meant to type, but i guess i missed the "for the hinge pin" part.

What does the shaved u brace do or help or make better? Also, does it need to be used with the c hub only? Thanks!

The c hub lowers the roll center. shaving the u-brace and mounting the ball stud lower raises it back up. The theory is that lowering the link in general makes for different roll center behavior, even with the roll center starting locations can be adjusted the same as A hubs and a normal brace.

In general, people shave their brace and go to a c hub at the same time, but using A or B hubs with a shaved brace is also a very valid tuning option, allowing for a significantly higher roll center. I run A hubs with shaved brace and 2 washers with green rear springs at my track -- this is what works at my track. White springs on a higher bite surface are typically paired with c hubs and a shaved brace followed up by ballstud tuning at the inside brace.

Run what works, don't be afraid to experiment.

Bob, where are you racing outdoors?
