Eurospec 280mm rear brake upgrade, MK4

dirtride · Oct 25, 2014

Has anybody tried this kit that can provide feedback? Eurospec 280mm rear brake rotor upgrade, solid ~ not vented but drilled and slotted. Uses stock calipers with extended mounting hardware. Not sure how the rotors will clear the dust covers or if they have to be removed/trimmed.

Also are coated with a grey substance (paint) that I assume is a corrosion preventive, but how will that effect the pad wear when installed?

why bother? The rear brakes aren't all that effective on our cars in the 1st place.

Better off upgrading the front brakes if you really want to upgrade your brakes.

Agreed the fronts are a better upgrade - that said I've sold plenty of front and rear kits and the feedback on the rear kits has been very positive.

I have a set of these, solid-NOT drilled nor slotted, on my Mk3 with 5lug conversion.
Mainly purchased for filling the 16' wheels to match the aesthetics of the front brakes, 312mm rotors with Boxster calipers.
But Eurospec 280mm did noticeably increase stopping power,
and the pedal feel with the Boxster calipers was phenomenal.

dust covers had to be removed.

the grey substance/corrosion preventive, doesn't effect the pad wear once installed

So if you have big front brakes these rears are a nice match/upgrade.

That's nice to hear. I have an email to them now asking how much the 280mm solid rotors cost without the brackets.

BleachedBora · Oct 26, 2014

You need the brackets to make it work FYI...

yes, I'm talking about the second time I need rotors. I was planning on buying the first set from them and if need be rotors after that.

Thanks for this info, it is what I was looking for.

And yes, these will compliment the TT front set up I see in the future.

Ok, the rotors alone are $94.50 plus shipping, just got a return email from Eurospecsport

Each? Or for the pair?

did you upgrade the brake master cylinder to use the Boxster calipers ?

Email I got said for the set. Bora Parts is a dealer and is confirming that price. I got the email directly from Eurospecsport

No, the piston sizes in the Boxster calipers are a close match to the stock caliper's area. So the stock master cylinder works fine on mk3 & mk4 installs.

The greatest improvement comes from the rigidity of the Boxster caliper and the increased rotor diameter.
The resulting pedal feel leads to a huge increase in confidence in the brakes.

Since the kit is close to $300 with the brackets, I would imagine the price is EA for the rotors.

tongsli · Oct 29, 2014

They gave me the wrong pricing.

3L3M3NT · Nov 7, 2014

I upgraded to the 280mm rear rotors and I've been happy with them. I'm not sure how much of an improvement they make, since I upgraded to 312mm fronts at the same time, but overall there was a noticeable improvement in stopping distance and brake pedal feel. The upgraded diameter also helps fill in the gap between the rotor and 17" wheels that are on my car.
With 18" Aristos

Hope that helps.

Very nice

Installing mine this weekend. I assume the e-brake cables are long enough?

Nice. Did you have a problem with brake lines or brake cable?

Lito,

To start, this kit comes without any instruction or pictures. Just the parts. Sure, it is pretty self explainatory, but still....
Brake lines were no problem. E-brake cables were a little shorter than I like after the caliper adaptor installed. What I did was "open up" the clip on the bottom of beam arm to allow the cable housing to move back a little for more slack. E-brake now works just as before the mod.

My only concern is I had to remove the splash shields for clearance. You cannot just bend them back because the rotors are deeper offset and sit a little farther in to line up with the caliper adaptors. Since I did not want to R&R the axle stubs/bearings, I ended up having to cut the shields around the radius of the beam arm. Not hard to do but the ABS sensor/tone ring and everything is exposed now. Some have said it is nothing to worry about, but you know how it goes. The shields are there for a reason. My ring and sensors were overdo for a cleaning as well.

I know what you mean about the splash shields but the wheels/rims probably protect the rotors more than we realize.

thanks for the info on the brake cable. Still haven't decided what to do on my wife's 2004PD. This kit or the Audi TT rear brakes.

Hey,

In case you're interested, the larger splash shields for the 256mm vented rear rotors are larger and it looks like a 280mm rotor will work with it.

We should have some type of confirmation soon. There are two of us who are trying to upgrade to 280mm at the rear brakes.

Just FYI

Here are some images of the shield and 256 rotor

232 to 280mm

This bracket takes you from the stock 232mm to 280mm or a difference of 24mm

dirtride · Jan 29, 2015

I like this! It bolts right up to the beam I assume? I have another question for you, going to send you a PM.

I got the PM and answered. But yes, the 256mm splash shield bolts right up and in your case, you don't need to trim it in any way.

The only downside is usually, a new bearing is necessary because it's nearly impossible to pull the hub without taking the bearing apart.

Tmcbride · Jan 4, 2019

What rotors and pads are you using for the 280mm? I know the front rotors of a tdi are 280 but what are you guys using for pads?
