Hi all

Has anyone had any experience with the 4003 pad on the Williams? It's meant to be specifically developed for lighter cars. The blurb below:-

Ferodo's 4003 was specifically developed for lighter cars (Formula 3, Formula Ford, Formula Opel, Formula Vauxhall, Formula Renault, Formula Campus) and Rally use. 4003 is the most commonly used pad worldwide in F3 championships. The main characteristics of 4003 are:

* High coefficient of friction (0.48) at all speeds and temperatures
* Short bedding-in time
* Excellent initial bite
* Predictability and reliability
* Low drag/good release

4003 can also be used in the rear axle of front-wheel-drive racing cars (off-road, asphalt, track).

They have a slightly higher coefficient of friction than the DS2500 pads, so I can't see them being bad. Any users on here?

Thanks. :)

The coefficient of fricition is meant to read 0.48.

Thanks.

I can't find the FC data for the ds2500, only the ds2000, which is 0.42. I have the ds2000 (ds performance) on my RSi and I'm not particulary impressed with them. They're OK, but no better.

If the 4003 is designed for light cars then the fade resistance on a clio probably isn't going to be great

Thanks for the reply.

Apparently the DS2500's have a coefficient of friction of 0.42.

Would you not class the Clio as a light car? I always thought it was. :)

if you look at the examples, they're aiming them at cars which weigh half as much as a clio ;)

That is true! Just googled the weight of an F3 car.... 550kg is what I found.

Hmmm choosing pads is a real mine field!
