There is a Sweep F1 tire thread. No updates lately. Rear compound is way to hard for most any surface. The fronts were really good though.

I finally put my kit together, whoever drilled the countersunk screw holes decided to go a little too deep at the factory causing me to use 1mm washers for the the side links and pivot brace. All of the countersink holes on my tresrey is like that....ugh.

After assembly i tested the rotation and notice the main shaft has a good amount of runout. It seems that the it's probably because of the design of the diff housing to use a spring pin. I may order or call customer service to get a new drive drive axle assembly.

Besides some of the missing screws, wheels nut, and modifying the front end to be legal I'm pretty satisfied for now until I put it on the track. We will see if selling the f104 for this was worth it. I went ahead and ditched the roll damper for a spare tamiya one I had laying around.

Quick snap shot...

I am not understanding the front end set up on this car at all. With going through this thread, I am even more confused!

I want to run the 190mm set up with rubber tire. I am not understanding steps 12 and 13. If I run the 190 setup, do I put suspension arm mount insert with the white mark in or out. Also do I put shims under the arm mount inserts?

For the 190mm setup put the inserts in with the white stripe facing outside then use the outside hole on both the plate and the insert. Yes you still use spacers under the arms.

It can be confusing. You will still need to shim the under the arms, you follow the manual of use solara's guide. This is a picture of mine for approx 185mm, which will require the same modications solara did to the caster block, servo mount, and upper arm. Keep in mind the 190mm setup with tires and camber pushes the front end past 190mm making it out of spec of the UF1 rules. If you that rule doesn't apply to what you're trying to achieve with your F1 then it doesn't matter.

Yes, the rule actually made this very confusing....not the car itself.

If you are racing the US 190mm rule, you also need to check on the TIRE/RIM that you are using...if you are using the +3mm offset rim, you must use the 184mm setup....now, that is confusing.

Lets assume you are using the standard Tamiya, Pardus rim with 0 offset, on step #12 of our manual, the most LEFT (right on the edge) showing when using 190mm setup, you should mount the alum insert using the most OUTSIDE hole.....and on the step 12, on the carbon "H" plate...you mount to the most OUTSIDE hole as well...with 0mm offset rim, that should give you a 190mm front end.

Thanks for your image....however, you are saying, your car is setting up using the 190mm setting, using the outside hole for the insert, and outside hole for the H-plate...when mounting with tires, looking from the front of the car, the lower portion of the tire is wider then 190mm?

Is that true..?

My current car, is setup at 184mm, when using Tamiya rim with Pit Shumizu tires, the widest part of the tires are at 186mm.

I will try to change to 190mm set up and use the same tires and see it can be 190mm or it is wider....

Not taking away from his post, can you explain the horrible runout of the rear end? I may even post a youtube video to show this.

What I have currently mounted up is a full set of Tamiya foam wheels with Shimizu tires. I currently dont have any fancy tools to measure width. At least that wide any way.

So the clear answer to my question is, that I need to do all that modification that Solara posted for it be 190mm compliance? ( Im kind of having a hard time understanding 3 different answers)

I'm not sure it is. I think it's the hub and roll pin side.

I'm using your setup guide and did the modifications. I'm running pits and my width is around 186-187 with slight camber. When I did the 190mm setup according to manual with pits mounted and neg camber is was around 192mm

How many spacer you put on the hub and did you enlarge the inside diameter of the 1st inner shim bigger? If you have too much shim within the hub, it might wobble because the wheel might not be deep enough to the HEX wheel hub.

That I will have to check it myself...after the 3 weeks Asia trip.
