Upgrade for 240mm Standard Brakes Atom 2 - 3.5

Post by K20A2 » Wed Dec 30, 2020 5:51 pm

I was looking for an alternative to the Alcon brake discs which unfortunately was very unsuccessful, but during my research I found some information, which may be interesting for those who have the standard brakes front and/or rear. (I hope it has not been posted before...)

I learned that the Atom hole pattern 4x 3,75" (95,25mm) and centre hole 56,6mm was used for the MG F and MG TF and there seems to be a little company (and probably also others) offering upgrade kits for these MGs in the UK.

If I am right, the affected MGs do have brake disks with the original dimensions:
- 240mm diameter
- 43mm total thickness
- 22mm thickness of friction surface front (vented) and 10mm rear (solid)

If the discs of the Atom standard brakes do have the same (or very similar) dimensions (I only know, that 240mm is correct) it may be possible to still use the standard brake callipers (and handbrake) but upgrade to 280mm discs.
There will also be spacers to reposition the callipers.

Most likely not as good as the Alcons (I hope ;) ) but perhaps worth a try for 175-250 GBP per axle.

Do you have found a solution here in Germany for new brake discs?
Maybe a 2-part (bell+disc) solution?

Referring to the Alcons the only alternatives I could find are the different versions from Skunkwurx and Komo-Tec would provide some on request. I was told they are the same like on 996 or 997 GT3 apart from the dimensions obviously. However they are quite expensive.

Sorry guys that I answer in German - that's more easy for me and it's a procurement problem here in germany - not in UK.

Erstgenannte Webseite bietet aber nur noch die Reibscheibe an, nicht mehr den Bremstopf. Bei dem Zweiten kaufe ich nichts mehr. Sein Verhalten geht gar nicht. Ist aber anderes Problem und hier nicht für die Öffentlichkeit tauglich.
996 oder 997 GT3 passt vielleicht der Scheiben-Durchmesser, aber nicht die Scheibendicke, der Lochkreis und Topftiefe.
Denke Topf müssen wir hier in Deutschland uns selber machen lassen, Reibscheibe dann von passendem Hersteller. Alcon geht gar nicht, da Die nicht antworten und die Beschaffung äußerst schwierig ist. Nicht mal der deutsche Importeur bekommt von denen ausreichend Antworten.

Many thanks, that's the way. :tu:
Don't understand the "pr" behind the price.
Is that per piece or pair or what ever?

Did anyone make any progress here? I see Ariel list the sports package discs as out of stock for both the atom and nomad so I’m also looking for options.... A Euro based supplier would be ideal!
