Thanks for the part # and info on the front tires.
Which kit is that # from?

I know for sure that the new C rears are very, very soft. Similar to the premounts that come on the 15th ann. car. and the Supersoft donuts available.
I got some and they work good for a few laps then they must heat up cuz they go away and then start to melt down to nothing very quickly.

Haven't seen a set of the new C fronts tho but if I'm not mistaken they would be very well balanced with the C rears cuz Tamiya's sets always seem to work great together.

Definitely could stand a harder front for this surface tho.

Steve, hope you didn't think I was takin a shot at you and the driveable statement.
I'm just not gettin to that point, not even close so my car could surely use some help in the traction department.
I've had some sharp guys helpin me out, Tom included and if I'm not mistaken
not many have their F1s super dialed.
I'm seein lots of us strugglin and just thought it would be a little more help if the surface was just a tad more forgiving for us and the tires/setups we have available to work with.
I've put in a bunch of track time (luckier than most, I live nearby remember) with as many setups and tips as I can dig up with the tire combos and suspension setups of choice and the car is still a huge handful for me.

This Sportsman is just lookin for a little more control to keep it as fun as possible.

I'll get by like the rest of em cuz it is the same for everybody but just sayin.

The other option would be 84094 ,these are the new C tires, which may be the same compound, I dont know cuz i dont have them, but if you want to loosen up the front end to get it to push those would be a good starting point
Have you ever used the F1 Hard cap tire?
I fits the F1 rim but is a cap tire vs insert + rubber.

That part # came from the manual for an old 103RX, but it is still a good # and is available and in stock at Tamiya America

Are you talking about the one that looks like a section of bicycle inner tube?
Yeah we ran those way back in the day, but they are a pain, you have to stretch them over the foam and them trim them and glue the edges, and the edges never stay glued. But yeah I have run them

Yes.
I won a set back in the day, always had it in my box of tires with the thought of maybe some day, one day they might be worth running. Probably need a good bonding agent, which was not really available back in the day

Thanks for the tip, that would make a huge difference.

Wish I had a couple more days to try to score some.

depends on what you run on the fronts
HBR softs should give a decent amount of grip in the rear

I have not run on the new surface, I am coming at it from the standpoint of not trying to get more rear grip, but to settle down the front end. Softer rubber is also more sensitive to weight transfer, so a firmer tire should make the front more neutral. really you are talking about actual mechanical grip vs balance.
If I was there, and having issues this is the way I would be approaching the problem, because you will never create enough rear bite to overcome excessive weight transfer.
Do you have a flex t plate?

oh HBR soft rear and HBR medium front was the hotness on the old surface

i haven't tried the new surface yet (even though i live 5 minutes away, how sad is that!)

Ok,
so that borders on pathetic, but oh well, no ones perfect
I can ask you all the questions, but that would be a waste of time.
This is the way I would set up the car for the conditions, not saying it will work, but this is where I would start
Fiberglass chassis
Original F103 front arms
3.5 offset steering blocks
Black springs, some sort of grease on kingpins
Tie rods on rear hole
Stock upper deck(not the one that ties the chassis together
Shock almost dead horizontal
2 hole piston 40wt oil, foam puck in the bladder
Flex t plate with o rings on both ends medium tightness on the screws,
or the pivot ball setup with a bit of slop
Soft damper springs, medium pressure on the plates
I have a couple theories on the shock spring, not sure which one is right.
My hunch tells me go stiff, with just enough preload to have the spring under tension
Kit front tires, and probably kit rears or HBR soft rears
5- 5.5mm ride height
Alot of the problems could also be how the radios are set up and how the speedo is feeding the power in. Thats more of a on throttle problem though, sounds like the issue is under braking which is a balance issue
Like I said, this is where I would start, and adjust from there
