Front brake upgrade

[Waterboard]

Across the Pumaverse there’s a lot of ‘go for fester ST150 front brake setup’.
I’ve tried a number of combinations using ST brakes and they don’t clear the Puma wheel.. so, what am I doing wrong???
Tks….

Which Puma wheel?

From what I just quickly read from this thread "ST150 Upgrade" if you have fanblade wheels you need a 3mm spacer. Is that possibly your solution?

Although, 3mm seems pretty small so it would strike me as still a tight fit & I may be tempted to go for a bigger spacer unless it has to actually be that precise.

In the past I did drive with ST150 brakes in the propeller wheels. It was real tight though, something like 4-5 mm left between the rim and the caliper.
Which upgrade you do depends on your goal. Do you need more braking force? --> Get better discs/pads first and see if it's enough. I recommend www.tuninghaus.de Most of the Dutch/German club uses them and they are great.
Do you want less fade? ---> Go for bigger brakes + better discs/pads.

No wheel spacer - this would make sense but yeah, it’s still gonna be close.
I’ve done all I can with the original brakes and tried many combinations of pads and disc… I favour tar-ox and the brand new ST150 discs are just sat there doing sweet nothing.

HI, I carried out this conversation a couple of years ago, I can confirm min 3mm spacers are required for propeller wheels. I knocked up some aluminum spacers that work well.

Hi, I did the same conversion about a year ago. I can confirm you will need a 3mm spacer to clear the turbine wheels. I knocked up some 3mm thick aluminium spacers and have 2 spare if you would like them, let me know.

Yes, you need 3 mm spacer for ST150 front calipers to clear the turbine wheels

So that’s the ticket,

I’ve got plenty of sheet aluminium so I’ll get onto this - all over again!!!

Thanks!
