Hi all.

I'm looking to modify my 3.0si z4 but want to start on the brakes first - any reccomendations on the cheapest most effective way to do this.

Thanks
 
A decent set of discs and pads will suffice unless you are going to be tracking the car.

As standard the fronts are 325mm, which is more than big enough for a car of this weight for road use.

This. :driving:
 
I’d leave the discs and lines as they are and just upgrade the pads. Performance Friction carbon metallics for the win :thumbsup:
 
Only advice I can give is don't delay if they need doing. Just replaced mine the day before some idiot decided to do a right turn across me, needed all the brakes I cud find to miss him. I was doing 50 mph speed limit at the time. Quick pant change was needed afterwards.
 
As said,the the 3.0 Si had bigger discs than earlier 3.0i......
Start with Performance pads,and a decent set of grooved/slotted discs and braided brake lines if you want to go further.
EBC are well priced,or Brembo for not much more.
 
Just bought a new set of front Brembo grooved front rotors and pads, waiting to install this week. 210 with sensors from carparts4less, decent price for Brembo a I think. I use to buy ebc for my 350z, but they double the price of Brembos
 
Lots of good advice and sensible suggestions here

I upgraded my brakes a while ago using part of a kit I had for my E36 but sold the car before I had chance to fit them.

Porsche Boxster S calipers with E46M3 CSL discs and fitting kit, matched with standard E85 3.0 rear calipers and vented discs

I know it’s a bit over the top, but considering I had the parts laying around it made sense to do it. If I hadn’t already got the Porsche calipers I would’ve gone with the 3.0 front setup with good pads
