Default 3 shoe or 4

Hi all. Just to lay a background. I have a MBX7 coming in the mail that I bought from another RCT member. I am going to put an O.S. 21 XZ-B VII engine into it that I have used for about 2.5 to 3 gallons. My question is what is the performance difference between a 4 shoe clutch and a 3 shoe clutch. I have a few 3 shoe flywheels and lots of shoes and more coming with the new buggy. From what I have heard is that with a 4 shoe clutch you can tune the clutch more than with a 3 shoe. Is this true?
I am looking at maybe getting the Reds 4 shoe clutch kit and using it. I just dont want to spend 50 bucks on a clutch that wont gain me anything. Thanks for any help.

Yes a 4 shoe will give you more adjustability for different track conditions. Look at the M2C racing clutch, 4 shoe's plus you can change what weights you run on the flywheel further aiding in tuning from track to track.

You will get everyone's opinions on this. As a fact though 4 shoes have more contact area and therefore should provide better bite but it's completely up to users opinion. 4 shoes are more tuneable as you've got 4 springs and 4 shoe material types rather than 3. But in my experience 4 shoes wear faster. Tbh 3 shoes are no better or worse than 3 shoes. Just run what you've got and what you can replacements easily for.

3 shoe clutches should have more surface area than 4 shoe setups. I suspect this is partly responsible for why many people seem to get more life from their 3 shoe setups. I've run both and have been happy with both. I switched to the Werks clutches about 4 years ago because they're so simple to work on.

4 shoe clutches set up properly are more consistent, more reliable, easier to work on and last as long or longer. Plus your clutchbell bearings will last much longer.

I've tried, stock Losi, m2c, buku, and different shoe types and I tried werks 4 shoe and since then I haven't looked back on anything else but werks, very easy to work on and I also bought a fly wheel puller and 3 werks clutches super light, light and medium and some extra shoes for my Losi truggy and it's so simple to just pop off the whole assembly for different track conditions, oh and one more thing I use is TKO clutch bearings, I'm just over a gallon of fuel on one set

Sounds like a 4 shoe is not a bad idea. If I get a 4 shoe it will probably be the reds 4 shoe. Has anyone used it?

There was a red 4 shoe on my truggy motor when I bought it, I had a werks sitting on the shelf but ran the reds twice. It felt great just like any really, but I cant speak to longevity. Never really tried to tweak with it or anything just drove it to make sure my engine was good.
