front wheel 4wd jconcept tires

[Rozzy]

i just got jconcept goosebumps for the front wheel on my 4wd buggy the inserts that come with them do we need to cut them down ??

It depends on how you want the car to feel, I usually cut to the width of the wheel and start from there

Can you please explain that? I mostly race 1/8 buggy so I have still to learn 1/10 "secrets"!

It depends on quite a few things, sometimes the same change (wider foam for example) can do the exact opposite to what you expect.

If you have a soft surface you might find you will get more grip with a firmer/bigger insert, as the harder foam forces the spikes to dig in.
On a harder surface a softer foam might give more grip as it collapses it presents more surface area to the track.

Because there are so many factors involved the best thing to do is experiment, what's the surface like you are running on, and what tyres are most people finding work best?

In the Greece there are two race tracks that we use for this year's racing.

Although both are only dirt the first one is a small tecnical track with low traction. I started this season with LOSI Studs in my B44 but I found really fast that Proline Bowtie at the back with some old Proline Stubbies work really great on this surface. I also got some JCONCEPTS Goosebumps as well which I think will work great!

The other track is much bigger and was hard packed for the first race. I used JCONCEPTS Barcodes and my car was performing really great much like a touring car!

So what's the best thing to do in order to have more traction from the goosebumps in the small tecnical track?

How dusty is the smaller track and how hard is the surface?

If the Proline compounds work better than Losi then the JC tyres should be even better as from my (limited) experience with dirt tyres the JC rubber is similar in feel the Proline.

It's very hard to go wrong with Green compound Double Dee's, as every time I've used them no-matter what the dirt or conditions they have worked great - they seem to have a very wide window when they will work.
Goosebumps are very simlar in that regard, except they will be better on the dustier/looser end of the scale, where the Double Dee's will be better suited to harder/less dust.

Does a smaller pin tyre like a Holeshot get clogged with dirt on the smaller track?
