Oops, I meant Sport - its the LRP Pulsar Sport unit which I have - the Comp was just too expensive for my use.

The shape a foam tire gets when it wears depends on many things. Of course the camber setting is important but during driving the chassis and suspension move. Thus caster, roll-center, springs, length of the upper arm and even tire hardness influence the final shape of the tire.

In the end you just look at the shape the tire gets after running and change the camber setting if you don't like the way it looks. For me I like the fronts to wear flat. But in the rear a slight cone to the inside (inside smaller than out) stabilises the car a little (it's sort of like a little extra toe-in).

You are right in that the coning of the tire slightly reduces the angle between tire and ground but there is nothing you can do about that. If you change camber the tire will wear into a new shape and the end result will be close to the same.

Thanks for the answer Julius!

I was running with a -3 camber at my track, but found that the tyres coned - therefore I thought I'd had too much camber - I then reset it to -2 and then the rears wore evently. My thinking was then that this must be the optimal camber as the most grip is use from the tyres (i.e. no side is being worn more than the other) and my camber angle remains constant.
And my thinking was that if I set my camber to -3 that after a short time then the tyres would wear in such a way (i.e. cone) that I'd end up with a -2 camber anyway.

I guess that relates to my question that I asked earlier.
I guess my question was too vague.

I have been told that this body give move downforce for better steering plus its a cool body !

I was wondering about this one, too. Why are tyres cut so in 1/8th?

I don't cut them but it's the same as what you mentioned with the camber. With new tires you need to run them in according to the set up you have so the reartires wear conish. If you'll cut them taperred they are good from the start.

It is not Kawahara that has the S710 parts, but rather Kai.
They have a really nice graphite conversion kit.

I was hoping that some place like The Border in Netherlands would have these available, but not yet. You can probably deal directly with the original company.

If you find a good place that sells the kit, please let us know.

Thanks, !!



That body is horrible , specially the serpet one. I drove and Alfa yesterday and I had all the steering in the world.

see my body !

Luckily I'm in Surrey .. south east. But then again, I've only managed to race outdoors only once so far. We'll see later this month.

Do you guys remember someone bought a impact dogbones that are now comes in black color just like the regular one? In fact we did receive some new shipments and they are, indeed, in black...

What I would like to ask is, I remember someone over the factory claimming it was in the same quality as Hudy spring steel.. With all do respect... How do you know if it is in the same quality?? they even look weaker than the 710 standard bones.

Oh, that's ok, no need to worry there - it'll be as dry as the sahra within in couple of weeks You'll be able to look forward to a good summer with moderate temps (max around 32 Degrees, average around 23).

Cheers, Mark.

I was the one who contacted the Dutch Serpent distributor (which basicly is Serpent). I got a reply from Bert Trumpie stating that the new black ones are from another supplyer but from the same quality...

Honestly I'm not sure what to believe, but I would be very very very disappointed with Serpent if it's not the truth...

I'm trying out the Arrows tyres/rims hopefully this week. They look nice (see pic), but one curious thing is that the socket for the wheel hub is larger than on the Serpent rims - this means that the wheels have a bit of play before I tighten down the wheel nut Hmmm, I'll see how they perform before judging any further.

Hi,

Would I be right in thinking that I should take the diameter measurement from the centre of the tyre when the tyre is coned? i.e. if I want to use equal sized tyres front and back, then with the coned tyres a central measurement should then correspond to a central measurement of the non-coned tyres?

Cheers, Mark.
