Default Parts

Mibosport has lots of Yokomo parts. They are in Europe but shipping is quicker than one might expect and not excessively expensive either. If you canít find what you need at either T.Q. or AMain, then Mibosport is a decent option.

Default BSR purple stripe wheels

Hey guys, what kind of screws are u using to mount the rear wheels?
I noticed I can't run BSR/CRC wheels in the rear with the kit screws.

I have been able to use kit screws with BSR/CRC. You just need to press a little harder when screwing them into the hubs. I have also noticed a wobble in the tire when tighten too tight much or not enough.
Alternatively if you can find Serpents #411061 screw allen M3x8mm special head titanium.

I use Xray screws when using Hotrace tyres. I suspect they will work for you.

Yesterday evening I listed a really nice YRX12 in the for sale forum. It’s a complete race ready car that comes with extra chassis plates (1 graphite & 1 aluminum), spare parts, bodies, etc. A great race ready package for someone looking for a sweet Yokomo car......just in time for Snowbirds.

You might have a little bit bent rear wheel hub if multiple sets of tires are wobbling always on the same side when you tighten all screws tight and 1 out of 3 screws must always to be less tight to fix wobbling.

The head of a button head/cap screw for metric is slightly larger than imperial screws which interferes when inserting a metric screw into a CRC/BSR tire. Look at the the inside of a BSR/CRC tire and you will noticed a cone around the mounting holes. That cone creates an interference fit when using metric screws and not imperial. Imperial screws drop right in. I always have to apply some pressure to get a metric screw in a BSR/CRC tire. When using Ulti Tires there is no interference fit because the head of the screw does not touch anything. So no I do not have a bent hub.

and some Stock action from Saturday

More than one person thinks my car is dying in the corners and lacking corner speed. I tried going up to a silver side spring but it just became harder to drive and no faster.

Two questions. What does thinner or thicker damper oil do on the front dampers?
Also now the car has been run a while there is some slight play in the front king pin should I shim this out or leave it as is?

Hi Tim, regarding king pin play I shim it out. If it's just 0.2mm you can also wind the kingpin out a little bit to remove it.

I've never tried anything other than 1000 in the front damper.
