fordom Member 145 Member For: 15y 7m 28d Gender: Male Location: sydney Posted 20/03/12 06:28 AM Share Posted 20/03/12 06:28 AM Hey guys, its time to change my front rotors on my f6 (4 piston) brembosim just wondering which rotors you would choose and why? I have decided to run the ferodo ds2500 pads, but not sure if its worth the extra $300 for the 5000 series over the 4000?the car will be fitted with braided brake lines, and 5.1 fluid and will be tracked 1-2 a year, other than that it is a weekend car.thanks Link to comment https://www.fordxr6turbo.com/forum/topic/79374-4000-or-5000-rotors/ Share on other sites More sharing options...

I've had the 4000's and 5000's. 5000's noticeably lighter and being unsprung weight that is compounded. Biggest benefit I found though is they dont chew through front wheel bearings like the 4000's did. Heat is not transferred as much through the alloy centre hat. I also go through one set of front rotors every year, so changing just the rotors is a bit cheaper (I think....may be wrong!)That said, if I wasn't taking my car regularly to the circuit, I'd save $$ and buy the 4000's. On the road, there is no difference. Link to comment https://www.fordxr6turbo.com/forum/topic/79374-4000-or-5000-rotors/#findComment-1212303 Share on other sites More sharing options...

I suggest getting those but slotted only ,not drilled. 1 Link to comment https://www.fordxr6turbo.com/forum/topic/79374-4000-or-5000-rotors/#findComment-1212307 Share on other sites More sharing options...

The weight benefit and heat transfer might just lead me to pay the extra for the 5000's. Especially if I decide to keep the car long term Link to comment https://www.fordxr6turbo.com/forum/topic/79374-4000-or-5000-rotors/#findComment-1212394 Share on other sites More sharing options...

Also consider that the ongoing cost of the 5000's (disc only replacement) is significantly lower than the initial investment in the two piece assembly.Anyone who goes through two sets of discs a year may as well go with the best.They should be a hoot with the braided lines.

I kept a set on the front for 200ks, replaced them with Brembo dics and gave the DBAs away free to needy home just to get rid of the noise.

I also use the ds2500 pads and have had no issues at all.
