Will the EBC 300mm BBK fit under 15 inch wheels?Fiesta st

This is ebc balanced brake kit for the mk7 fiesta st. i chose the 300mm version in the hope i could still keep using the 15 inch team dynamic pro race 1.2s i currently have.
This video is all about testing to see if its possible

I'm impressed by how many of you have mentioned scrub radius. It is a concern to me but I did not explain it in the video for simplicity and also thought no one would understand. I guess I was wrong lol.

[@akkual]

I am just happy too see content that they actually will fit for 16". Many big brake kits (ok, these are not that big) mention that one needs to use 17". I live in Nordics, and I need my 15" or 16" winter tyres, as there's no 17" proper winter tyre option in size that would fit Fiesta ST. I can get 205/45R17 from Continental, but those are super expensive size and hard to find, 215/45 would be easier, but likely won't fit at all.

[@williamwagstaff]

I have been looking for a video like this for a while thanks for making it!

[@Sparkplugsteve]

Thanks glad it helped.

[@steve19901988]

So a rule of thumb is, the bigger the wheel the better the brakes fit? My friend got the 330mm kit and we are scratching our heads as to what offset the new wheels should be. I have the fullrace A from Braid on et40 7x17 and on my 300mm tarox kit it fits perfectly, you can even fit an extra finger. But I don't think the EBC's will fit under an ET40 wheel. Our goal is to not install spacers. By estimate, do you think that ET35 would be enough?

[@cooperSpartan117]

Wouldn't it be best to run the 16's with a 3-5mm spacer and spend the extra on tyres when needed. My concerns with the 15's and a 25mm spacers is that the scrub radius will be way out messing with your tuned handling. Also the thought of widening the track by 50mm just using spacers, won't the wheels poke like mad and upset the balance unless you also do the rear? Not wanting to shut down your plans just hoping to get some insight

[@Sparkplugsteve]

Hi. Yeh I will have a pretty bit positive scrub radius with them. It's not ideal but it can still work. Il probably get more torque steer and some wandering on braking. It's something I did want to avoid but il try it and see how it goes

[@kevinevans3237]

Good information Steve. Hope it all works well, yes I agree the callipers look good and the wheels looks awesome. 👍👍

[@bryandebruyn4410]

Love the vids Steve. Always in for a challenge it seems. Wonder how you will like the EBC brakes. Found a great secondhand deal myself on a Ksport 304 BBK. Fits nicely with 20mm spacers on standard wheels and good for the 16" winterset I hope too. For track use I found a 25ET 17" set which clears the brakes nicely without spacers. Keep going making those vids

[@19marshall80]

I went with the mountune 6 pot big brake kit 302 discs, fit behind OEM wheels no spacers needed :)

[@philivey4300]

Bloody hell.. Ordered EBC discs and pads on Wednesday, that code would have been handy 😂

[@Sparkplugsteve]

Iv been spreading it around for a few weeks. Shame you missed it.

@@Sparkplugsteve I'll be sure to use it next time, don't worry 😁

[@Pwilliamz]

i work for an engineering company and ive had people bring wheels in for the inside diameter turning out so they will fit over the caliper. i guess it all depends on what colour trousers you wear i guess lol. great vids ste keep them coming.

Yeh that scares me lol.

[@DanielP-c9g]

Another great video steve! Cant wait for the LSD and big brake kit videos. I wish i could get a big brake kit for my car

[@Pu1gcerda1]

Hi Steve, Just to add to the suggestions, could you not get a machine shop to weld up the holes in the carrier and redrill them a few millimeters closer to the hub? as a few mills on the radius will mean a lot loss spacer. Secondly, whilst you are looking at the brakes, have you thought about replacing the servo , perhaps one from a Mondeo ST or even a transit, as they are likely to give you more pressure. Keep up the great videos and keep safe Phil

[@eddb2994]

Feel for you Steve, would look MEGA with this setup... would having it spaced out that much look silly? (As well as affecting geo) Is there an option of machining the team dynamics or speccing some custom ones from them directly? What about other rims like OZ etc

[@chriswhite5843]

I actually thought from watching your track videos that it was already really good on the brakes.

[@Sparkplugsteve]

Yes it is. But heat is a big issue and I'm cracking discs very easy.

[@chriswhite5843]

@@Sparkplugsteve Fair enough, good luck with fitting them. Looking forward to the next track video.

[@rivalrepairs]

Hey Steve, what is you current scrub radius on your wheel setup?. Do the wheels have OEM offsets?. If you add 25mm outboard to tyre tread center you could introduce some dogey handling characteristics im sure you will be able to notice. Maybe you could take some material off the caliper :-) or best going with the 16", if you looking for performance gains on track. Maybe worth buying Competition Car Suspension: A Practical Handbook. Thanks for you vids

[@Sparkplugsteve]

Hi and yes scrub radius is a big concern of mine. I didn't mention it but don't worry it's been considered. Thanks

[@NicolaasPhotography]

You are going to love those!

[@davidunderhill1343]

Very informative Steve, Hope it works out ok for you, myself I'd go for 16s , always enjoy watching your vids 👍👍

Hope you went back and checked they still fit with the hose on.

[@mattwills87]

Should be fine just went back to look were they attach on the back

[@esoxecosse66]

Hi Steve, just caught up on watching all your video's from YBO & ONO up to present day, have enjoyed it all immensely, it's amazing what you've achieved from that wee shed, one thing I have noticed is there doesn't seem to be an air compressor in there ? I might be wrong, I bought one a few years back on a whim and use my one almost daily, can't understand how I managed without one now, anyway I'm waffling lol, keep it up, your video's have been great and only getting better, cheers

[@Sparkplugsteve]

Hi Mark thanks for the comment. Glad you liked the videos but no i don't have a air compresser. Limited space.

[@b4rr0s]

Videos are brilliant, keep up the great work! :)

[@midlifecrisis9269]

16s are far less hassle. The scrub radius will be to big on the 15s. No doubt you would get it to work changing settings and it will handle ok on track, but it may handle like a mwchin on the road. Hard to say until you do it I spose. Nice brakes though 👍

[@dixiedean2911]

Great content very helpful for the track cars 😁👍

Are 17 inch tyres sum times not cheaper that 16 inch tyres ? I know that they are a size up mate but sumtimes a 17 is cheaper

[@chriscotton2555]

hi steve. not entirely relevant but really coincidental that I've just got home from a 600mile round trip to Glasgow from Atherstone collecting a pair of Hi Spec 4 pots for my maxd out stage 2r...at a bargain price, may I add. The price was the enticement but having to have bigger brakes has finally caught up with me. it's going to transform the car! (mine fit under 15's but are being fit under 17's, so no sweat). keep up the good work pal. maybe see you at a track day

[@DJM-Racing]

What size discs are you using fella? I wanted to fit the 300mm ebc kit under my 15" dynamic wheels but going off the clearance diagram they sent me they wont fit. Tried to contact hi spec but they don,t reply.

[@Sparkplugsteve]

Dan iv already done a video in testing 15s over ebc 300mm kit. You need a big spacer which runs into other issues with arches

[@DJM-Racing]

@@Sparkplugsteve it's going onto a race car with adjustable top mounts. So the tops will go inside the arches. I already have 25 offset wheels so that should be another 10 mm clearance.

[@Sparkplugsteve]

@@DJM-Racing just realised this is the video lol. Yeh so you may do it on a 15mm spacer

[@DJM-Racing]

@@Sparkplugsteve trouble is without buying it I can't tell for definite.

[@jamiesweeting1770]

I’ve been running ebc 330 brake for about a year now , the yellow stuff pads lasted about 5 laps of Blyton park and they were done , so I’ve swapped to rp1 Bit of a tip , when you come to bleed the brakes , roll up some blue roll/ paper and get all the excess fluid out of the centre of the bleed nipple The bleeder goes really deep before it seats in the calliper and your left with some above the seal, under the rubber dust cover , so when it gets warm it weeps out and makes you think they are leaking ......... just my experience with them mate 👍🏻

[@Sparkplugsteve]

How did the rp-1 perform?

[@jamiesweeting1770]

Spark Plug Steve haven’t has chance to get back to Blyton yet , booked for 26th sept , now with blue stuff on the rears and rp1 up front , ebc did recommend blue on the fronts too but I don’t want another track day cut short due to brakes so gone with rp1

[@fordyford]

Jelly AF. That's a rad kit Steve. Keep in mind expansion with heat, generally if you have a couple of mm clearance it should be OK but it is something to keep in mind. If EBC want to donate a new kit I'll happily do many more track days and review them time after time lol. Enjoy mate.

[@Sparkplugsteve]

Haha. I was thinking about that yes. If it rubs it will self clearance lol

looks to me like it's just catching the sharp edges of the caliper, i've ground off the edges on the caliper before with good success, sound brutal but does work.

[@Sparkplugsteve]

Yeh I'd also do the same but the brake pipe that joins the the 2 half's is equally close and I can't alter that. But I will fit them up again and see if a bit of shaving can reduce the spacer size to a 20 maybe

Forgot to ask, is there another style of 15" wheel available that might need a bit less spacing it out ? Cheers

[@jameswilson8820]

Do they work OK. What's the cost of the kit

[@isoconfused8744]

Can't you get the edged of the calipers machined down?

[@leighrichards9111]

And maybe lathe the inside of the rims slightly aswell

[@TheJambo2014]

I'm sure I remember one of the aet cars (Ben I think) used to run 15" team dynamics pro race 3s with a BBK without Spacers. Remember asking him and he said pro race 3s fit with BBK but 1.2s don't

[@Sparkplugsteve]

That's good to know. Il look into that.

[@MrAdammurphy1993]

Yeah pro race 3s are designed for big brakes, i need 20mm spacers on stock 17s for a 330mm revo kit but the 17 Pro race 3s go strait on with no spacers

[@jackford5216]

What’s the reason for putting 15’s on instead of the standard 17s? Any benefits to this, just curious

[@Sparkplugsteve]

Cheaper track tyres

[@Amsinckster]

Cant you move the caliper in and get a deeper hat/center for the disc?

[@Sparkplugsteve]

No the disc would hit the ball joints.

[@Amsinckster]

Spark Plug Steve ah okay. Sometimes there’s a few mm to get there

10mm spacershould do

[@alanparis7256]

Would be more easy to grind a bit off corners on the calipers and repaint calipers.

[@Sparkplugsteve]

Its an option yes.

[@alex98uk]

Been looking at these, but I really want to run my 16" without a spacer to save the hassle of switching studs (they're already et35). Anyone know if the AP Racing calipers are any thinner and less likely to catch on the spokes than the EBC?

[@Sparkplugsteve]

Look into whether a 5mm spacer can be used without changing the studs? But even if you change the studs it's a real easy job.

Is 300 big? My boring Skoda has 312mm discs

[@Sparkplugsteve]

It's bigger than the 280 mm I have now. 😁 It's not just the diameter through. The disc is thicker and has better internal cooling vanes. The calipers are much larger so they dissapate the heat better . And being fully floating disc they are far more resistant to warping and cracking. But yes your disc are big boys

Sell the 15's and tyres and the money from those, buy 2 sets of 16 inch rubber, sorted 👍 saves dicking around with spacers and maybe damaging something...🤷‍♂️

[@mikeberry304]

Taking it too far out Steve , there will be no support on the hub flange , the studs are there only to stop the wheel from falling off , all the weight is on the flange , all the geometry will be cocked out again causing camber, excessive tyre wear , easier to just put the 16 inch wheels on bud , sell your old 15 inch wheels , the flange is very important for support for the wheel support

[@Sparkplugsteve]

I wouldn't actually drive the car with the washers I fitted today lol. I will use bolted spacers but yes it will alter the scrub radius but camber will not change. Thanks for watching.

[@mikeberry304]

@@Sparkplugsteve make sure the wheel centre is still sitting on the flange of the hub or you will need to extend the flange to sit inside the wheel centre , as I said the wheel is supported by the flange

[@RS_Rowe]

mike berry the wheel is not supported by the flange 🤦🏼‍♀️

[@mikeberry304]

I think you will find that it is , the studs are not designed to take the weight of the car on them, they are there purely to keep the wheel attached to the vehicle , the centre of the flsnge iof any wheel hub is designed to fit inside the centre on a wheel , that is why the hole is a similar size to the wheel centre , it's not put on the wheel to put a badge on it , it's there to support the weight of the vehicle
