VW Racing Big Brake kit product review
danishmkvgti:
So what you're saying Dave, is the Tarox 2 piece calipers is to be avoided? :wink:
:sad1:
DaveB@Vagbremtechnic:
That's unfair to say Jake, a lot of the most popular and successful calipers are two piece. If I was going to make my own I'd want to ensure they were of an advanced design reflecting the most modern design and manufacturing techniques.
Two piece calipers are a third of the cost to manufacture than monoblock unless you're making 10000 at a time
I'd also like to say I'm not for certain saying the VWR caliper Has rigidity issues, I just can't think of any other reason its reported that it works better upside down than the right way up, Caparo no doubt did the analysis.
Regarding rigidity some mono block calipers have a bolt through pad retaining pin to help, some two piece calipers such as the R8 rear (a caliper i really rate for a mk5) have a reinforcing bar across the front face as does the larger R8 front which is monoblock and has a re bar as well
We tested the xyz calipers on the bench with some pads and a hand levered master cylinder and the flex was very visible, we also then tested an AP Racing CP5020 on which the XYZ caliper was "based" which did also flex but nowhere as much, the castings will evolve over time with added mass and material. AP have had 40 years to get that casting correct.

Thx Dave, so calipers stay, but will catch you regarding your floating discs :drinking:

if you cut out the hype of which calipers people are running, in the pit lane it's simply down to what pads people run. The calipers at that level are simply there to hold the pads in the correct place nobody gives a rats arse what calipers you run, it's accepted they're up to the job and pads are what count. There's a place for the VWR kit, my issue with it is Value for Money, I've not commented on my own personal viewpoint on the kit until now, take the badge of it and it's a £1200 inc vat kit which would be competing with Forge, K-Sport, XYZ, willwood., Hi-Spec. ..... What aspect of the kit makes it £800 more expensive?

I'm getting value for money with my kit as I'm the development car for my particular kit which is a 4 pot setup instead of the current 6 poT option. Id understand if I was paying alcon money, so imnot losing out as much as others

It strange as my brakes are strong the amount of times I have lit the emergency lights up just by giving them a good jab :signLOL:
