Massive Brakes!

In a word yes, how much it weakens it is anyones guess.

[e30Alex]

yes but there will be a fine line, do you know if its been done?

[Martinaston]

No idea, you'd need to find one that matched the hub centre hole. 66mm.

[stuartgallafant]

the audi tt discs are your best chance. as far as i know, you have to machine 1mm out of the centre hub of the disc, and then drill 3 other holes.

drilling the holes wont really weaken the discs a great deal, as long as the holes arent extremely close to each other and you've drilled them properly

remember, that the big old wheel you put on there is sitting tight upto the disc anyway

[e30Alex]

Hey everyone, spent all day researching big breaks, and i have come to the conclusion that z3 suspension arms with 2.8/3.0 disc/caliper setup will be the cheapest Vs power. Am i correct in thinking these z3 arms are a direct replacement?Im pretty sure ther are. Feedback please!Cheers Alex

[e30Alex]

bump!

[Martinaston]

Depends how much you can get the arms and struts for. Then you need the five stud wheels and tyres to match

[e30Alex]

Ive got the wheels already, just need to know wether the arms are a direct replacement?I think the e30 struts will bolt straight onto the z3 items. I think i can get the brakes relativily cheaply. What do you guys reckon?Alex

[bigdek]

z3 stuff bolts on

[e30Alex]

hehe, im glad that has been confirmed!if there good enough for a z3 3.0, there good enough for me!

[stuartgallafant]

what advantage is Z3 lower arms gonna give you? if you bolt the strut off the E30 upto it, you're still gonna have the same hub arent you?

[suzie650]

What's the offset (don't know if it's the right term for brakes) of an e30 disc?


Edit: Found it It's 35mm...

[e30Alex]

Hey Stuart, as far as im aware the z3 kingpin, the bit the caliper ataches to, will not fit the e30 arms.I may be wrong, please tell me if iam!

[stuartgallafant]

e30Alex, can you be a bit more specific on which parts you want to use?

im assuming you'll be using Z3 strut/hub assembly?

[stuartgallafant]

anyone know where you can buy JUST the wilwood calipers?

rally design

[stuartgallafant]

buster, whats the best one's to get on that website? bang for buck wise?

i dont wanna spend a fortune, but i'd spend good money on descent calipers, rather than cheap money on crap

[buster]

dunno mate,i bought some of these :



I was going to be using the audi tt disks,but then i changed to 5 stud.
Also ,the calipers wont fit behind the bbs splits so im just using standard m3 for now.

[stuartgallafant]

jesus!!! how much were they!!

[buster]

£450 each
I only paid that for the pair though.
Plus £110 for ebc red pads

[stuartgallafant]

wow, i think i just threw up in my mouth!!!

thats a f*cking lot of money!!

[buster]

LOL,you can get them cheaper,i just like new shiney good quality stuff.
Used ones on ebay all the time.
Just a shame that i cant use them now unless i change the wheels.

The Z3 front setup is E36 stuff. The kingpin bolts to the strut on the Z3/E36, its all one part on the E30 - the Z3/E36 kingpin will not fit the E30 strut.

You can use the Z3/E36 complete front struts in the E30 (with other parts), but it will mean a swap to 5 stud.

[stuartgallafant]

i've seen hundreda of E36's and hundreds of E30's, yet i still dont know what you're on about!!!

Kingpin - part 2 in the link.

[stuartgallafant]

oh right, the hub! king-pin/hub, whatever!!

so what adavntage will this give anyway?

[jmc330i]

None as it wont fit the E30 strut.

Fitting it with the E36/Z3 strut will give you 5 stud and larger (E36 size) brakes, but you do get the wheel alignment problems although that can be sorted.

[stuartgallafant]

you wouldnt even have to remain 5 stud.

im pretty sure the front wheel bearings from an e30 would fit the e36 hubs

[jmc330i]

The E30 M3 fronts might fit the E36 stuff, but I dont think the 4 stud E30 stuff will. The E30 M3 and E36 use larger front bearings than the 4 stud E30s, Im sure its been discussed in one of the many 5 stud conversion threads and I dont think its that easy - if it was, I would have 5 studded my car by now.

Anyway, if I was going to the trouble of fitting the E36/Z3 struts and brakes and making do with the slightly out front wheel alignment, Id sure want to change to 5 stud to make it worth while.

[stuartgallafant]

how does it put the front wheels out of alignment?

is this any good matt?

[Martinaston]

Don't temp me, i've decided to go with the E46 325 (54/22) calipers and have just spent the last couple of hours out the garden making some brackets.
I gave up looking for them as the only ones i'd spotted looked too deep, i could still do with a picture of the back of those calipers to be sure if anyone can help.
Has to be the one with 57/25 ate stamped on it.
Cheers anyway Stuart

[jmc330i]

how does it put the front wheels out of alignment?

Using the Z3/E36 stuff moves the wheel backwards in the arch, so the wheel is off centre and there is also an effect on the camber IIRC. It can all be sorted by using the lower arms from an E36 M3 Evo (97+) and some other offset bits and bobs, but it will still be a little out.

If you read up on R3vlimited.com some say the E36 stuff effects handling, but TBH, Im not sure if it does - maybe noticeable on an out and out track/race car, but not so much in the real world. It certainly wouldnt stop me using the E36 parts to convert my car.

[stuartgallafant]

fair enough james. cheers dude

matt, what master cylinder you going for? you'll have to show me your setup coz it sounds a lot cheaper than 4 pots!!!

[Martinaston]

I'm hoping to use the E34 25mm master, the rod that sits in the servo looks longer than the E30 one but still has the same amount of travel. the only problem is it may catch the diaphragm when fully pushed in, but hopefully that won't happen once its got the fluid in it.
I'll have to have a better look at it later, i should have a pic somewhere.
