The cheaper way to convert to 280mm brakes

[grifty]

Hey guys,

I stumbled upon some build threads on various froums stating there is a cheaper way to upgrade to 280mm brakes. I have put together a parts list for the conversion below.

This conversion requires no rotor spacers or caliper bracket machining. It also does not require re-drilling brake rotors to 4x100!!!

This only works if you are currently running stock 262mm knuckles. If you have 242mm ones you will need to upgrade to 262mm ones first. This will work on any ED/EF/EG/EK/DC/DA.

1. 262mm kunckles.
2. Bendix DB1206 pads or any of your choice as long as they are the same design. DC2R pads are the same as well.
3. 17CL15VN calipers and matching brackets. You will need to trim the dust shield to fit the calipers. It's a 1 min job.
4. DBA2526 or RDA7996 rotors, these numbers are for blank rotors.
5. 1 inch master cylinder with matching booster.

The rotors are from a 2007+ Mini Cooper non-S. They are 280mm in diameter, 4x100 and have the same centre bore! The lug nut holes are a little bigger but this wont effect anything. These fit perfect without issues, no modification required all bolt on!!!

The required calipers can be found on CG Accord V6's, DC2 Type R's, Odessy's, Legned's, BB4/BB6 Prelude's & CRV's. Don't be fooled by paying top dollar for ones that came from a Type R, they're all exactly the same. You can pick them up for $50 the pair.

Master cylinder & booster can be used from a late model GSI Integra, EK9, DC2R, BB4, BB6, V6 CG Accord. Just make sure it has the 1 inch marking on it.

I paid $132 for the RDA rotors from my local parts store. you would normally pay $190-210 for the RDA 282mm blank rotors redrilled to 4x100 + $40-50 for the spacer or caliper machining. That's a saving of over $100!

Also another note, this setup will pass a engineering inspection & design as well if you are looking to get it done.

Performance rotor part numbers:

DBA 4000 series T3 slotted: DBA 42526S
DBA 4000 series slottled & c/drilled: DBA 42526XS
DBA T2 slotted: DBA 2526S
DBA slotted & c/drilled: DBA 2526X

Confirmed to fit over EM1 stock wheels & EK4 Blades.

So the mini cooper rotor will clear the caliper without the 3mm spacers/machining calipers?

Yes that is correct.

what's the centre bore size on 262 kunckles? 56.1?

btw found this on h-t
"the caliper you'll need is known as the 17CL15VN front caliper.
the 17CL15VN is one of the biggest single piston calipers honda produces.
you can easily identify this caliper from the stamp.

this caliper can also be found on:
97-01 ITR,
97-99 CL V6,
91-95 legend,
96-98 rl,
95-98 tl,
92-94 vigor,
95-02 accord v6,
91-97 accord wagon,
97-01 crv,

not 100% sure on the centre bore size but the mini cooper rotors centre bore is the same.

[pat88c]

great information so grifty

would be great dies to size rda or dba disc rotor to double check it and screen shot each disc rotor

look forward to more update

I'll do some research myself too interest in this option too

[mocchi]

fuark nice grify. +1 bbc penetration

btw FS: BNIB mini rotors $120

Good stuff mate :thumbsup:

Used this setup on my daily/track car for two years without issues, Mini Rotors work really well; like OEM.
Also using this setup on my current build, got my mini rotors from the States for $80 delievered. :D

[carayan]

Gonna head down this road in the next few days, I have to ask though, did you have to modify your lines in any way? Or it did it fit right up?

[grifty]

They fit perfect. The same size line and bolt is used for the brake lines. Only modification you will need to do is trim the dust shield around the caliper.

Good stuff, and any year BB and calipers fit fine?

[grifty]

Yep as long as the have the same caliper code that I posted in the original post. Would most likely be a BB4 or BB6.

[curtis265]

Repped. Good thread.

Thanks grofto

[dougie_504]

How do they go clearing rims? Do they clear most 15" setups. IE Fat Fives, EM1's? Aftermarkets?

[grifty]

No Idea, but this setup would be the same as any other 282mm.

From my research they fit under Fat fives, don't know about the EM1's though.

[carayan]

One thing I have found, that should probably be noted, is the difference in models. I have to get mine ordered in, and they asked if it was R50 or R56. R50 is fine (2004-2007 iirc, 4x100, 280mm, 56.1mm cb, although be careful, this varies wildly), but some of the R56, even the non-S models, showed a 292mm rotor and different centre bore. Just a heads up, not sure if it's valid, but this is what I was told when ordering the rotors, so yeah be careful, some people don't know what a model number is...

[grifty]

That's weird. You shouldn't have any issues finiding the correct rotor. 07+ non-s 280mm. The 04-07 ones won't work.

I'll get the dimensions up shortly.

I found it strange as well, but someone said they'd look into it for me and let me know, so hopefully it was just a database error or something. Nonetheless, better to be safe than sorry.

this would be very wheel dependent, and theres no way it would fit under stock wheels. my specs are 16x7j +40 and my wheels just cleared everything, so yeah.

[grifty]

Sorry guys, havent had a chance to install the new ball joints and wheel bearings into the knuckle yet, will update once its on! I hope they fit under my rims haha!

http://www.minis.com.au/minis/catalog/product_info.php?cPath=71_85&products_id=1524 are these the right rotors?

[grifty]

They seem like it, you just need to make sure it for a 07+ model.

Hey mate, are these plain rotors and what brand are they? Can you get slotted as well? PM or post here price if available delivered to Melbourne.

Would probably be best to PM him, dont know if he checks this thread alot.

[jspec civic]

Any pic of which part of the calliper needs trimming?

[grifty]

Its not the caliper that needs trimming, its the dust shield. Needs to be slightly trimmed around the caliper. Can do it easily with tin snips or angle grinder.

[BG-33P]

Any information on a matching rear brake upgarde as well??

also, in regard to the retaining screws in the center, i noticed the mini disc only has one hole but does it line up with the hole on our knuckle?

If the lug holes are a little bigger then original, i'd like to have that retaining screw line up.

[pat88c]

As far has I know the rear disc brakes are enough

the only way you can get the hole to line up is to put old disc on top of new 280mm disc mark the hole then drill hole
or drop it off to machine shop to do the job if you think you can't do it

but I would worry too much about it missing lug hole and nut as once the wheel on it clamp the disc to the hub

hope that helps

You can mark it and drill it, they are exactly 100mm apart. But this wont make any difference. Majority of cars dont even use retaining screws as torquing the wheel correctly is more than enough.

[DC2-PWR]

Yep just torque the wheels up and you will not need the screw. I've been circuit racing without them and no problems.

awesome. great thread btw :D

[euRo_noob]

Would the stock replacement rotors be able to withstand all the braking at track? Will it warp?

I got a quote from RDA. $120 each for a plain rotor or $150 each for a 'custom' slotted and dimpled rotor :S

Cause I plan to track the car and just wanted to know what sort of temperatures can the stock rotors withstand. Those RDA can withstand I think over 600 degrees?

[grifty]

No idea when it comes to temperature ratings.

$120 for a pair or each? $120 each is ridiculous, JDM Yard sells them for $132 the pair blanks, slotted should be around $180-200 for the pair. I think RDA Slotted should be fine if you do a cooling lap as recommended. I do recall Yonas using RDA slotted on the EGK24 at the track.

[euRo_noob]

It was $120 EACH.. That's why I was a bit iffy... If it was 180-200 for a pair of slotted, I can fork that out.

DC2R calipers for $150? :\

[grifty]

That's too much for each, I paid full retail $132 the pair from my local parts store, just get a set from JDM yard.

Type r calipers are expensive because they have type r tax lol.

Refer to first post which tells you what calipers you can use and should be able to pickup for around $50 the pair, exactly the same as type r ones.

is it a must to run 1inch booster ?

im currently running ek4 on the ek1 =/

[mocchi]

gives much better pedal feel.
feel dat feels m8

[grifty]

Its not a must but highly recommend, the ek4 one will have more pedal travel compared to the 1 inch

[broken-wheel]

so it retains a working ABS ?

[grifty]

so it retains a working ABS ?

Yes it does as the ABS ring is on the driveshaft not on the disc

They also clear EK4 blades for anyone who wants to know.
