How about the Fironi clutches?Are they the way to go for racing? they look like they would hook-up great and give a constant grip.
Please let me know,it's almost race season.

For the cost of one Fioroni clutch I get 10 sets of carbon shoes for a 'normal' clutch.
But what do I know, I never tried them.

I can't tell you how those clutch shoes are but you don't want the shoes to grab to much. If they grab a lot they bog the motor out of the corners leaving you in the other racers dust. I use kyosho aluminum shoes with 1.0 springs and I don't have a reason to change that.

Super,thats what I'm looking for,input.I'm new to this 1/8 buggy stuff, so I'm looking to go in the right direction,thanks, Butch

Aluminum shoes and 1.0 springs are the ticket to happiness for most driving conditions.

EDIT: I believe Kyosho uses one style and shape of shoe, and Mugen (and most other companies) use another. Make sure you get the right aluminum shoe for your application.

your standard clutches are just fine for racing. 1.0mm springs and alluminum shoes is a great place to start and then you can go from there, if you need too.

I have found that the WERKS POWER Clutch is worth the investment for my Xray XB8. I run four carbon shoes with the lightest (I think its the gold one from memory) of the three springs that they provide. I only race at club meets etc (no bashing my racing machine!!) and I have found that with a little patience (and my new one piece engine mount that allows me to set the gear mesh once and for all) this clutch is very reliable given the 'one big spring' design as opposed to relying on three. Installation is soooooo much easier than standard three piece clutches. To make things better again I have just ordered a new adjustment nut that will allow me to adjust the clutch through a small hole in my clutch bell without taking the engine out at all! I have heard and read that the the RMV and Fioroni examples are excellent- but the WERKS is quite a bit cheaper. The RMV is 35 bucks more- thats the equivalent of two full sets of spare shoes for my WERKS clutch. I am about to experiment with running two Carbon Shoes and two rulon shoes....

In conclusion I choose to invest in the clutch for $70 odd dollars (US) as I really wanted an XB8 but I had heard that their clutch/fywheel set up left a little to be desired. As I understand it they have resolved this issue on the new XB8TQ that has been launched in the last few days.

If you are going to spend money on a clutch as a replacement or hop up for racing I would recommend the WERKS clutch for sure: heres a link for the clutch kit:

and one for the new adjustment nut which would be a must have given the relatively small price IMO

The kyosho shoes are the same as mugen only kyoshos have 1mm larger holes that the pins on the flywheel go through. If your running a kyosho flywheel you either need to drill mugen shoes slightly larger or just use kyosho clutch shoes.

I use Mugen shoes in my Kyosho clutch bell and flywheel. The Mugen shoes are half the price and work just as good, but you do have to drill the holes out a bit. They are a little different when you look at them, but the contact area is the same.

Thanks alot guys, it's just the info I was looking for. Sometimes at the track or LHS you get all kinds of ideas of what to buy, but nobody will tell you how good or bad the stuff works.I've heard more reasons to buy the expensive items and sometimes I think its an ego trip for the racer,not a better part. I'm new to this racing 1/8 scale and I know I can get good advise and concil from the RCU members.

While on the subject of clutches, some cars use tiny flywheels, and some use normal ones. I think the Hyper and 777 use a small one, and I am pretty sure the MBX5, 7.5, and 9.5 are standard size units, but am not sure. Any others that you know fall into one category or the other?

the kyosho clutches sit back a little farther and shroud the front bearing of the engine from debris. the mugen does not. thats another difference in design
