Stoptech ST60: Blank/unfeatured rotor discs?

Goalient31 · 06-05-2021, 06:44 AM

Does anyone know if there are replacement rotor discs for the Stoptech ST60 BBK front that do not have slots and/or cross drills?

I don't think so. What's your reasoning for wanting them?

You can probably get a set from Coleman Racing. I assume someone already sent theirs in to get measurements but if not, you can send your old rotors in and they can make blanks. lutfy did this for his, IIRC years ago.

There is, I have order before. But you have to order direct. They don't over for the rear 355mm only 380mm from my knowledge

Generally, neither feature adds benefit other than to accelerate pad friction degradation. So looking for a quality blank disc replacement to get longer pad life on track.

For anyone ever looking, Girodisc now offers 380mm blank rotor discs for the ST60 kit. GD380.32.52 is the part number, and you just have to call them to let them know you don't want slots before you place your order. $800 a set. Really good service over the phone too.

Yes that is for the ST60. Not sure on the Trophy kit but I thought everything is the same except caliper spec? Give them a call to confirm, they were helpful over the phone

StopTech "Aero Brake" rotor rings are cheaper at 350 per side plus 10% discount from BuyBrakes.

31.846.1101.01 (Left)
31.846.1102.01 (Right)

What the benefit of the Girodisc rotors at more per set? Does it include the rotor hat as well or just the ring and hardware?

Ximian · 07-19-2021, 07:42 PM

I got in touch with Girodisc and they don’t make the 380 rotors for the ST60 yet.

Richbot · 07-21-2021, 09:09 AM

Looks like they can only help with the rear ST40 kit for our cars right now (355x32)

My original question was looking for discs WITHOUT slots or cross drills. The reason is increased pad life with very little to no performance loss. To my knowledge you can't obtain Stoptech discs without those features. Interesting they told you they don't mKe that, they told me they did… Did you reference the Girodisc part number I included above?

31.846.1101/1102 are the part numbers for the blank rings. If StopTech still makes them, that's another matter.

I didn't reference the part number since I assumed their sales manager would know what they have to sell.
