I have been using the red spring from my TRF417 spring set.

I wish I had a good one, I did however try and try for weeks to get mine settled on very high grip (opposite of low grip at Tamiya Worlds in Japan).
I found my best setup was to lower the front as much as possible, 3mm ride height was all I could do with 2 mm spacers under top arm assembly.
Be careful cuz now the upright pins can come out if not recentered perfectly up and down since the lower arm flexes on impact. Trust me.
Tried to raise front end to calm it down like I do on asphalt but this made it much worse, would grip roll at slow speed like crazy so I slammed it as much as possible and also raised the rear to 4.5mm.
Found that best.
Soft rear side springs, light oil 20w, Gold spring from Miata Mini kit, light 2k lube on side damper, 2mm droop and 1mm sag helped me to get on power and not have to drive it between corners, it went straight from A to B like this.
Front springs did not give me much of a different feel so I stayed with golds there.
Had to settle on living and dying by how much sauce was applied to front tires, rubber, i.e. 1/2 to 3/4 tread width max.
Carpet hates me but had to try.

PM robk, he's the guy I should have called on day one.
The crap above is just what I did by hit and miss.

I'll be honest I have had a hard time getting the steering out of this car that I want. There were a couple setups on here from Mike Gee and Robert B (from timezone GP) that are solid. The big problem is getting the car to steer middle out. The regular F104 front end would probably solve the steering thing, but it's not TCS legal if that's a concern. The car, for whatever reason, seems to accelerate way harder than my other Tamiya cars and I feel like if the steering can be found it would be crazy fast.

A couple things that I haven't had a chance to really try out would be a longer servo horn (like the exotek extension for the xray servo saver). It's more angle in the steering rods. The only bad thing is while you get more steering like that, on carpet it tends to make the front end not want to roll through the corner. It bites, but kind of binds up.

The other thing would be to use less spacers at the servo saver, so the steering rods look more like this ^ when viewed from the front of the car. This changes the bump steer, and usually has more corner out steering.

I wish there were some other caster options. From a crude measurement, I think it has 7-8* of caster, but I tend to think 5-6* might be better for carpet. The VBC car which has a similar front end has a 5* option which seems to be what they use from the setups I have looked at.

Thanks for the info. I am very close to just retiring my TRF101 since my other F1 is working good and a few more tweaks could be better.

For asphalt, I have had to resort to using Yokomo soft front F1 tires which are extremely aggressive to get it to steer good. I only put these on the TRF101, none of my other F1 cars. Been running this way for about a year and half.

Tried to make it work for carpet but was just no good.

Just built the carbon front end. As expected, Tamiya quality fit and finish.

But what's up with all the shims? "Introducing the all new 4mm shim." And a lot of them. On top of servo...7mm worth of shims. See pic. Gotta be a better way.

I have the 101w and i just added the 2mm alloy shims which are for ride height when running 103 foams and maybe more needed if you run the 104 type wheels.

Still trying to find my front kit. Ordered from Hong Kong 3 weeks ago and speed post says left there facility. US speed post says waiting to be shipped. What the heck. Hope I haven't thrown away 90 bucks.

Does the battery to the front, speedo to the back configuration yield more or less steering?

With most Speedos there isn't much difference in weight distribution. In general a higher rear weight bias will turn in better off power and a higher forward bias will have more on power steering.
