Subscribed. Good luck. Are you using front rotors and just putting them on the rears?

 

It's similar to what the Speed 3 guys do for a inexpensive upgrade. Moving the caliper farther out will provide more torque and help balance out the brake bias, at least that's the plan. Mazdas have a different bolt pattern than Ford but Volvo has the same bolt pattern. So I'll be using a Volvo rotor and a Mazda bracket.

I got some schooling from Todd on braking and help from Alex for part selection.

Researching has shown me the the ST has a somewhat unique rotor size. similar sized cars have a 280mm and the heavier cars have a 302.

 

Success!

2010 Volvo V70 302mm rotor vs the ST 271mm. The Speed 3 gets a 280mm and uses the same caliper.

2008 Mazdza 5 bracket. Parts.com for $75, Mazda wants $108.

Thanks Alex for suggesting the proper bracket.

 

That's all one needs? The volvo rotor and the caliper bracket??

If so, I'm all over this. Thank you for sharing!!

 

Yup, that's it.

 

I bought budget rotors because I wasn't 100% this was going to work. Slotted rotors should be available.

Might as well get some SS lines from TCE to finish it off while you're there.

 

So, Kevin, I assume your track time has lead you to want to change the break bias? When is your next track day so you can report back on the results?

 

March 21. My braking points will probably have a significant change.

This what I did to the front a few weeks ago.

This was to help equal it out. Speaking with @Alex@Stratified the ecu might learn to adjust the bias. I don't want to put words in his mouth so maybe he could comment on that further.

 

NICELY done sir!

 

Awesome - had a feeling this would work out! Glad it did Kevin!

The car has EBFD and I am not sure how much of it is learned but it definitely uses it as part of stability control and ABS.

Thanks again for your help.

 

word

 

Just verifying, this still retains use the factory handbrake?

 

Yes

 

Do you have any pictures of the Brackets side by side to compare the stock and the upgrade? I like the idea of keeping the factory look in the rear just larger rotors.

 

I forgot to take some but this a pic of a Mazda 5 bracket next to a Speed 3, they all look the similar

The Speed 3 it taller than the ST

 

very cool, nice write-up

 

Damn this seems like a very good upgrade for not a lot of money

 

If you can find a crashed 5 to rob from you can do this dirt cheap! I couldn't find any in Phoenix area.

I'm working on an idea for Frankenbrake II. This would use a vented 22mm rotor but would in addition of a different bracket (not the 5 ) would need calipers. You'd be looking at a factory upgrade for around $450. In an unrelated question, anyone have access to a 2013 Volvo S60? :big smile:

 

Word on the street is that the Volvo s80 brakes bolt on the front but they are massive and no one really makes performance pads. This rear setup is more than enough even for heavy track use with the right pad.

 

Just a hair bigger than the 14.5+ ST rotors at 336mm vs 334mm

 

Amazing thread. Great job.

Question on the diameter for the rear with the Mazda 5 bracket limits us to 300 or 302mm dia rotors for the v70 2010. What is the max thickness we can run with our calipers on these rotors? I see you have 11mm and 12mm is available and there are also much thicker veined options out there for the v70 that meet all prerequisites if max thickness our calipers can accept is known.

 

The bracket will only allow the thinner solid disc to pass through. the vented 22mm is not going to fit. I'm not sure what the max allowable is for the caliper but visually it does not look like a 22mm would fit.

 

Someone should put the parts together and sell this as a bolt-on upgrade kit.

 

It's really just the brackets. Pick your poison for rotors, StopTech, EBC, Stock, or any other manufacturers that might make a performance V70 rotor. Right now I'm sporting Duralast from Autozone.... Budget rotor for a budget upgrade.

 

Nice work Kevin, much props.

 

nice worK!

 

Does the bracket have to come from a specific year of Mazda 5? The volvo rotor is a rear rotor from a V70 2008, but a 2010 will also work?

 

Same rotor for those years. This set up is for a solid rotor and not the vented. The bracket is pre 2008.5. Use the part number I provided

 

Damn, so all this is a bracket and a volvo rotor?

 

Yes Sir, yes it is

 

Ahh on parts.com the caliper mounts are under rear suspension components not brakes. Explains why I couldn't find it on the site.

 

I'm just curious if a picture of the pads sandwiching the rotor could be posted? Would like to make sure the entire pads are making contact with the rotor and not hanging off.

Sent from another galaxy.

 

I dont have that but it's a perfect fit.

 

Damn I was just going to go with the Duralast autozone rotors with some new pads to check some things out before upgrading all 4 corners and the rotors are out of stock and unavailable.

I'll probably be ordering some EBC slotted rotors instead. But thanks for the info. I never even thought about other applications I could use to get bigger rear brakes.

@Kevin

Can you alter the first post in more of a How-to?

I am gonna sticky this.

I also added to your thread title so people know what this is before clicking in

 

Done

 

@Kevin what is your plan for the Fronts with an S50? I found a few at a junk yard not to far from me. Might be something I'm willing to do depending on the plan, and the significance of the upgrade.

 

It was an S60 for the rears. The S60 uses a 302mm rear rotor like the V70 but it uses a vented 22mm instead of an 11mm solid. You'd need to switch calipers, brackets, and rotors. My plan was to see if it would bolt up. Needs more research
