Hi,
What are your experiences with different brands and type's of brake pads/discs ??
I drive with OMP Racing discs and OMP (971) Racing pads fitted on my 33 16v...
And soon I replace the pads for Ferodo DS-3000 pads..
The OMP setup is good.. no fading or overheating on the track..
Hope that the Ferodo's do even better... ( they should as thay have a 0,62 coefficient of friction and the OMP's around 0.42 )

Hi Lon,
Whats the braking like, with the OMP setup, when driving on the road? (normally  ) does it brake well from cold?
All the Best

When cold it brake's like you have a not so very new original brake setup  ... (pretty bad but not too bad).
I think that with the DS-3000 it will be worse than with the OMP's ( as the OMP's are between hard use and track use in... and the DS-3000's are track use only  )

I use DS3000 on the front of my sud (mainly for racing) and I think they're great. The DS3000 are o.k. (maybe not great, but certainly o.k.) from cold too. The WRC guys use DS3000 - imagine Rally Monte Carlo or Sweden with brake pads that didn't work from cold!
One thing with the DS3000, I found the wear rate quite high on the track. Alfasud brake pads are very small and I'm told the wear rate is better if you can run vented rotors and duct some cold air to them.
When some race pads say they are for "race use only" it's often just a disclaimer to prevent any claims against the supplier. In many countries it's not legal to use non type approved pads on the road. Some race pads have high wear rates when used on the road. They are optimised for track use and wear rate for road use is not a design consideration, so if you use race pads on the road, check the pads often.

Here an update on the use of the DS-3000 for road use..
The wear is very low, after 3000kms the thinkness is almost as when new.
The thikness of my discs is not noticable decreased so that looks good too.
And when it comes to braking... 
No real brake distance tests done yet.. but the 100km/h to 0 is better as with the OMP pads fitted... ( less than 40 meters )
Does anyone here have brake distance reports for the 33 ????

I used to run Ferodo DS2000 on the 'Sud for track use, which I found excellent for the level of punishment I gave them (not too much really). I was told at the time by another club member not to run them on the road however as they are too hard and can score the discs when cold - does this sound right? I used to swap them for cheapy soft pads at the end of the day.

This is most likely also depending on the disc's you have mounted.... I use vented OMP Racing discs (22mm, grooved and bored) together with the DS-3000 pads it is mostlikly a good combination when it comes to braking hard even when cold..
Though when warm/hot the braking gets even better, so much that my front wheels often block, rear wheels do not block at that time so it gives a very nice cornering setup... I only need to lift my foot from the brake and give full throttle... and that was the corner... leaving some people starring behind me as they can't believe what they just saw..
I still need to test the DS-3000 OMP combination on the track, but when I have done that I will post an other update here...

The DS2000 are apparantly fine for road use, but they've since been replaced with the 2500 model (which I'm going to fit next month). |

Finaly after a long time.. I have tested the Ferodo DS-3000 pads with my OMP discs at Zandvoort..
When everything is warm, the braking distance realy is short.
From 180km/h to 90km/h was amazingly short when I compare it to my previous setup ( OMP pads and OMP discs )... instead of start braking at 150 meters from the Tarzan corner I could start braking at 125 or even 100 meters and stil have space left for even later braking poinst.. but i did not test that..
As I needed to drive home with my car i did not test the real braking limits as I did not want to end up crashing or standing still in the gravel..
