!!Brakes!! Help needed.

[HaydenVRX]

Hey guys just need some help from people who have experience with brakes on magnas.

1. I'm changing my Ralliart front brakes to 380 brakes.. Is this worth my time?

2. What are the best slotted rotors to fit the Front 380 brakes and rear ralliart brakes?

3. What is the best street pad that will also be made for both?
Looking at: -QFM HPX
-EBC Greenstuff
-Any other suggestions?

4.What is the best brake fluid to use?

Thanks alot in advance guys.

Why 380? You might as well go with front BREMBO ones as they are meant to bolt right up and accommodate a little larger rotor.

Fluid: I'm not sure but if its fresh and lines were flushed, stock should still be ok. Remember that some fluids can kill the seals.

If you wanna save mass then I heard (it might be incorrect) but DBA 5000 series are good and come in both slotted and drilled

1. If i get brembos i need rear ones too.
2. i'm 19 and not made of money like some people on these forums
3. I need to modify my wheels to accomodate them

..but i am still considering.

1. I'm changing my Ralliart front brakes to 380 brakes.. Is this worth my time?

DynamiteZerg went from the AWD front brakes (same as Ralliart) to the 380 brakes and thought it was a good upgrade. But then again, I went from the standard single piston brakes to the 380 setup and the difference wasn't as great as I was hoping.

Rotors are the same size between Ralliart and 380, it's just that the 380 rotor is marginally thicker, and the caliper/pad is larger.

2. What are the best slotted rotors to fit the Front 380 brakes and rear ralliart brakes?

DBA 4000s for the front.

For the rear, I'm not sure if any manufacturers do slotted rotors for the Ralliart rears? I had the feeling there was a group buy a few years ago, as DBA or RDA wouldn't make up an order unless they got a minimum amount.

3. What is the best street pad that will also be made for both?
Looking at: -QFM HPX

I'm a big fan of my QFM HPX. Low dust and noise for a performance pad, without sacrificing braking ability. I would definitely get them again.

[HaydenVRX]

Thanks for that red, Yeah only problem is i need The same discs front and rear so it looks the same (Otherwise i will cry)

Hmm really not sure about the 380 brakes but i really do want to upgrade.... I guess they are better then nothing.

Anybody got information on buying AWD rear discs and spacing to fit ralliarts?

[Dave]

Sounds pointless upgrade to me. Spend the money on braided lines front and rear, Motul 600 fluid, Ds2500 pads and decent rotors but not DBA 4000 as they are made in china now.

Brembos for the win though. Rear brakes do 20% of the braking so rear brembos are just wank factor. Much more sensible upgrade.

TRW GP600 Dot 4 Racing Brake Fluid

QFM pads (HPX or A1RM if you give them a hard time, but these are noisier and dustier.)


I thought the AWD and Ralliart rears were the same?

The only reason I would go to 380 fronts over the ralliarts, is if the ralliart calipers have died.

Best slotted rotors IMO are DBA, but again I'd only look at doing this when current rotors need replacing.


Personally I'd leave your existing rotors/calipers, get the TRW fluid and A1RM pads and the braided lines if money allows.
I reckon you'd notice a significant improvement.

Then if you want better results save for Brembo's.

[HaydenVRX]

Dave, Because they are made in china doesn't mean they are bad, they still get rave reviews.

Brett, The reason i was looking at 380 fronts is it's basicly a free upgrade, if I replace all my rotors anyway i can buy 380 fronts and sell my ralliart fronts with a difference of around $50

[Jasons VRX]

If its costing you nothing to upgrade the front then do it otherwise theres SFA between Ralliart and 380 fronts (ralliart caliper is cast iron Vs 380 alloy. Ralliart rotor is 294x24mm Vs 380 rotor 294x28mm)

Ralliart/AWD rear brakes will be fine with brembos on the front. Plenty of people have run that combo (myself included)

[vlad]

The alloy callipers will offer some weight saving especially at the front. I've also got the 380 front callipers and rotors. I have noticeda difference. Put it this way, each pad has 25% more surface area and the pistons are larger and provide more even pressure.

As for the differences between AWD and Ralliart rear rottors, the AWD ones have a taller hat height, but otherwise they are the same.
