Best 300mm Upgrade...


loveland said:
I am running a very similar setup engine wise and found my brakes aren't up to scratch anymore. I have just upgraded to Wilwood 4pot Dynalite calipers with 2 piece 310mm bells and rotors.

For the money this setup is awesome

I bet it is, but out of my price range. :(

Iceman - Drop me a PM with a price... I wont be ready to buy until April tho...

leave it with me, will depend on what new seals and pistons i have to buy and how much it costs me to have shot blasted

another suggestion is something like honda legend front calipers with 262 rear setup, i ran 282 25mm front discs with new legend calipers and good pads upfront and 262 rears on my ek4, amazing braking performance and never let me down on track, prob cost me more than a new aftermarket kit but was so impressed i stuck with it

im actually gonna rebuild them actual legend calipers as well even though 1 i bought brand new from brakes international and other was shot blasted and fully rebuilt at same time

car gone now so no good to me and gonna just sell them on
 
So the EP3 discs dont fit over the EK9 hubs... how do people get around this?

Is there a disc available in 300mm that will fit EK9 hubs... maybe S2000?
 
I encountered this problem a few weeks back I have a jordan and have ep3 calipers with ep3 discs re drilled to 4x100.

Then I have since 5 stud hub swapped my car and found the ep3 discs don't fit over ek9/Dc2 hubs therefor had to get the hub itself machined down to fit inside the bell of the disc fairly simple and cheap to do only downside is having to replace both the wheel bearings as the hub has to be removed from the arm

I'm going to post a thread about the ins and outs of this conversion soon so everyone knows the details of one hasn't already been done

The single piston ep3 calipers with good pads (I use ferodo ds2500's) is more than enough stopping power for the likes of a ek9 in my opinion and would be even better with performance discs but I just have blanks at the moment so get quite hot. Also doesn't break the bank to do the ep3 brake conversion

Yeah I dont wanna really machine anything as I dont have the tools... so may just stick with 282 setup.

I just checked and it seems the s2000 discs are a no go and ATR are 28mm thick compared to the EP3 25mm but should fit over the drive flange and hub centre ok.... not sure if there is any way to accomadate a 3mm thicker disc with the EP3 caliper?
 
Have atr front brakes with mtec race discs and ds3000 race pads and itr 98 spec rears with race discs and redstuff pads absolutely brillant setup in a fully stripped dc2 race car I'd go for the atr's. If guys are running 4pot ap and willwod calipers up front with just standard rears I'm sure you'll be fine. I've had a few setups and mine above was the best and they were well tested :) lol
 
I already have the Ep3 brake setup now guys....

I have an ATR as a daily so gonna try the ATR discs with the Ep3 caliper but dont think it will work.
 
This was my ep3 set up, grinded the calipers down to fit 15". Using 16" is safer

Doesn't work like that dude. Those AP and Wilwood calipers can (and regularly do) offer less brake force that the ATR calipers.

Although the ATR also uses 260mm rear discs like the EK9/DC2, the ATR brakes use a much larger piston in the rear calipers which is why the bias is OK. When used with the EK9/DC2 260mm rear brakes, it becomes front biased.

This isn't all bad, if you're running very wide, sticky rubber and have stripped the rear of the car out, it might be OK. A standard car on road tyres though, it won't perform quite as well as a setup giving less front bias, such as the EP3 setup. :nice:

Yeah ino that mate but is this souly a road car? My car was running r888 on 7inch wide rims with a 15mm spacer to clear the brakes with 15s and stripped out with cage was an awesome setup but as said the ep3 brakes should be more than enough with a good set of pads
 
I have ep3 setup on my ek4 if you don't want to machine the ep3/s2k front brackets brake expert on Honda tech will do you a set delivered if you don't mind paying does make it a bolt on mod though

Its not the brackets... on 5 stud hubs the ep3 disc wont go over the drive flange so not as easy to sort as grinding/spacing the brackets.

Think I'm gonna stick to 282's as these are going on an EG which will be pretty light 840kg ish.

I'll save the ep3 setup for another project!

It cost me £30 to get the drive flanges machined to fit the bell of the disc not alot of money your local engineering/machine shop will do it takes them less than a hour to do as I said before the only downside is having to replace the wheel bearings you also have to space the ep3 caliper carrier out to centre it on the disc with 5 stud hubs as the offset of the hub is different from ep3 and 4x100 it's upto yourself 282's are good on a eg just run some good quality pads and you should be happy enough with the stopping power but ep3 ones are unreal on my jordan
