Gents, regards the Griodiscs I fitted them to my B5 RS4 and found them very good. They are so much lighter than standard cast discs so help with unsprung weight as well. You can just replace discs as well and keep the bells. That was with 18Z Cayenne calipers.

They were 350mm 2mm thicker than std discs so again better for heat dissipation. I did around 5000 hard road miles and there was plenty of life left.

On that are there any mods required to fit the Giro sold for the C2 as if you going bigger disc surely you want bigger pads as well as Im assuming swept area increases?

340mm Giro discs use the standard caliper and pad, the discs come with spacers to move the caliper out to allow for the additional 22mm of disc.

Improvements would come from heat dissipation as oppose to pad contact area.

Giros are around £1k

Cayenne calibers + those Girodiscs sounds very tasty!

Just had a look at the price of the gyro disks on d911 and it's 450 quid per disk which seems a little steep to me

That's not bad if it includes the bells, spacers and so forth.

I was thinking more of the brackets...but yes I could do that, the hardest part is holding them in a jig.

Thanks, are they a straight fit onto a 996 Carrera 2?

2000 Porsche 996 Turbo

PostPosted: Fri Sep 28, 2018 11:27 am    Post subject: Reply with quote

Interesting but expensive thread on brake upgrades.

I have a 996 TT which is daily driven on the back roads between Peterborough and Derby. It is now nearly due new discs and pads all-round so I've been looking at the options.

Given I haven't the budget for the Giro or the 6 pots, the 350mm 997 discs looks like a reasonable cost upgrade.

My main question, is the upgrade to the 350mm discs from my 330mm ones worth it and will I feel a difference?

Second question, does anyone have the dimensions to get the spacers made, I have access to tooling to make them myself?

'll be looking at fitting some stainless braided pipes, tidying up the callipers and fitting up-rated pads too.

Thanks

Thumb

10mm I would assume if they are 20mm larger?

Cheers Rdodger,

I should have been more detailed, what are the bolt centres and sizes.

I use my car daily so would have to make them up prior to doing the swap.

Bigger diameter discs would require different calipers and/or mountings so that the pads sit on the swept area of the discs.

If, as I suspect, the discs have a larger swept area, they will require larger calipers and pads.
