VW Racing Big Brake kit product review

You should have said, I'd have come over - how long you there for? I must bust the office....

will text u next time

I think he's talking more about the spigot not sticking out enough to mount the wheel on, rather than the bell/hub.

Where are you testing?

this is exactly what i was talking about. I just got home, i'll make a shower and go out to test them. First impression is that i have a vibration in the wheel when i push the brake pedal. I just made 10 km. This night i will do about 200km. I hope that after some serious braking everything will be ok

More impressions later..

[xht20]

First impressions after 100 km: A lot of problems:

1. Excepting the fact that the spigot is not sticking out enough to mount the wheel on and i made a custom piece on CNC machine, like an extension of the spigot.

2. At speeds beyond 50 km/h if i press the brake pedal the car starts to vibrate very powerfull, it is like the disc was deformed. The steering wheel vibrates very strong, the car vibrates.

3. When i steer left at maximum something is rubbing at my left wheel. When i steer right at maximum there is no rubbing. I sounds like metal on metal  

4. The brake pedal feedback is very low, i have to push it very well for the brake to actionate

What i think that is the reasons are:


1. The vibrations could be from the custom piece. In the brake kit it was included a set of bolts longer than the normal ones. Could it be that there are strong enough to hold the wheel without the custom piece to be fitted? Could the bolts be forged?

2.  A fabrication fault of the brake discs

I attached some pictures of the spigot with the OEM disc mounted, a picture of the spigot with the VWR disc, 2 picture with the custom made piece

TEFF, with all those problems you list, your best bet is to go back to VWR and see what they can do. They'll want to solve these problems and are always very helpful in my experience.

been running mine for a while and they have been fantastic and i can drive them crazy hard but as Robin has said give Mat at vwr a call as thats not good as i think the spigot ring you have fitted will be making the car vibrate so get it off and bolt the wheels on without the ring and see if that helps.

i have sent what u said to Mat for u

I'm from Romania and i cannot go all the way to UK  . I know they are helpful, that's why i don't want to give up so easy with these brakes

i have sent what u said to Mat for u  

The only person with which i talked all the way from the beginning from VWR is Sam Roach. I don't know a guy called Mat

Thanks for the help guys

I would not like to try this method until i'm 100% sure that it  is safe. Until i get this sorted out i will not drive outside the city

Teff, the bolts will be strong enough - try removing your spigot addition and just be very careful to torque the wheels (with them off the ground for the first bit) a little at a time, picking an opposite bolt each time.

So 12 o'clock bolt. then the 5 o'clock, then 10, then 2 then 7 - it'll naturally pull the wheel central.

Rubbing noise might just be the screw in the arch liner, as you've increase the track width of the car.

As Mike says above and if its Sam your dealing with then thats fine but if u speak to Sam and i send the info to Mat we have both people covered

I will do so tomorrow because today i don't have the time to go to the service and remove the spigot addition. Please, can you tell me exactly on this draq which is the screw in the arch liner?


Thank you again guys for your support

its the plastic in side the wheel arch on the car nothing to do with the brakes

[MAT ED30]

the bells that are on my car is the old bells ie first prototype ones the can take a spigot ring

[xht20]

Oh i see, but if it was that, why there is no metal rubbing in the right side when i steer right?  
As i see in the picture you have enough spigot clearance and you can sustain your wheel on it and then torque the bolts

I just thought to a solution: if it's possible for them to cut the so called built-in spacer on the disc bell so that it doesnt covers the spigot so much?

[MAT ED30]

it would be better to have a mm taken off the bell to get the room u need
