4m6 - 36 / 44 = 2538 mm²
6m1 - 28 / 32 / 38 = 2554 mm²



3. aftermarket - mismatch:


Forge: 707 mm² + 1046 mm² + 1164 mm² = 2917 mm²

Im on the road to sorting my Ed 30 out. I had Tarox 6 pots on my old APR stage 3 MKIV and these worked well on track. I also looking around and was considering the road Tarox 10 pot kit or VWR kit or AICON
I also am ordering .KW Csports and anti lift kit before I get diff and APR STAGE 2. Any one using Tarox kit.

Tarox fail in salty and wet weather conditions. Anodized finish + no dust seals.
If you drive it daily get painted and properly sealed ones.

I had Tarox and as The bruce writes they are not ideal foruse on the road, and my set was extremely noisy so i went for a set of 4 pots with 370mm discs from AKS Tuning, they are miles better than the Tarox 10 pots GT34 with 330mm discs i had before 

[Msportman]

The Finnish on my old 6pots went off on the calipers but the pedal feel was great. The discs and bells were very expensive to replace. I may consider the VWR kit and others before deciding.
Tarox kit certainly performed well in my experience and they got a real pounding.
My track orientaated .MK2 16V does what I need for track which is somewhat holding me back on what i do to the Ed30.Icertainly will sort out suspension and brakes if nothing else.
Has anyone got experience of the anti lift kit? Will it stop axletramp?

[tony_danza]

I ran Alcons, I believe APR have them on their Golf R and Regal ran them on their MK5 the year it won the VW Cup.

In 2 years the discs were half worn and I'd used 4 sets of pads. Say 20k and track days into double figures.

Seals are internal, rather than Brembo style, so don't perish. Pads are generic Alcon shape, so vast range of options and about £120-200 depending on type. Clever anti rattle plates and staggered pistons meant they had very good road manners. I honestly couldn't fault them, and I'd buy them again every time.

I may well have a set of VWR brakes and a set of AP 330mm brakes both coming up for sale in the next week or so if interested?

Can any body confirm what is needed to fit VWR brakes to Cupra alloy hubs/carriers is it just 20mm longer bolts than what normally comes with the kit
