Brake Upgrade Kit ......

[sindako]

Mates , What do think ?

Tomorrow i'll take my conversion plates from the forge ,
i am Upgrading the brakes of my e30 ,
Using E32 Calipers , with Auti TT 312mm x 25mm Rotors .

I Guess Now the Car will Have Better Brakes ,
I've seen E30 with EVO6 calipers and rotors , Subaru Calipers and Rotors , Mercedes w124 brakes and rotors .
But those TT 312mm are damn too good , So I am Goin For it ,
Also It's Amazing i don't have to Miss up with my Hub and the 4x100 diameter , just the conversion plates and Some Rotor Redrilling .

Photos Will Be Posted Soon .

Cheers .

I'm just in the process of doing this conversion myself.

With calipers that big you'll probably need a larger master cylinder.

I've Read about it somewhere online , And The Conversion didn't include any master cylinder replacement , I'll try it on the OE Master Cylinder , If It's Rubbish i'll get an e36 M3 one or maybe a 7 series one .

I'll hit the Realoem to see what cars had the same cylinder as the E30 , if the 7 series had the same then there'll be no problem .

You don't want the same master cylinder as the e30 one
You need a bigger bore one with a larger piston inside

Did I comment on your post on Facebook?

7 series E32 master cyl a must have on this I'd suggest

std m/cyl will work but long pedal bigger piston area means the m/cyl needs to displace more fluid per stroke to be an effective upgrade

Do you need to change the brake flexis too?

I'm looking at doing this next year, and have Goodrich hoses at the moment, which I'd like to keep

Its either this or the Porsche 986 set up

But I want to find about the hoses before I commit

[Lurch320i]

My braided hoses fit the bigger a calipers just fine

Thanks Lurch

The bolt spacing on the E38 brembos is different to the E32 540i ones.

What's the minimum size wheel you can run with this setup?

[clarko74]

These will work with 16" Hartges but I think that is about the only 16"wheel that will work with this setup.

Thanks Clarko.

I use a 25mm master cylinder

Some pics of mine here - http://www.e30zone.net/modules.php?name ... &start=200

[Lurch320i]

I fitted this setup with my 16" bbs lm reps
No spacer required but I did take a grinder to the caliper slightly to clear the inside of the rim

[DanThe]

Whos make of BBS reps are they? Any pics?

[satan16v]

Will this master cylinder be a straight swap? And improve the pedal feel, when running brembos up front and 540i rears?

Demlotcrew had a set on his turd

My reps are from a company called bmautosport
They look like this


Forgive the state of them, I'm currently in the middle of polishing the lips and painting ther centers

[DanThe]

Any manufacturers markings on them?

If you fit a bigger ms because of larger pistons and having to push more fluid does this mean the rears are more likely to lock up quicker because of more fluid being pushed down the lines?

If you fit a bigger ms because of larger pistons and having to push more fluid does this mean the rears are more likely to lock up quicker because of more fluid being pushed down the lines?

Other way round, the larger m/c area creates lower line pressure for a given pedal force, the clamping force on the pads might be recovered at the front caliper with larger pistons (depending on the actual piston sizes) but the rears don't so you get a bias shift to the front.

Do you have pictures?

As I Have the same setup

540 brakes and tt discs

the calliper wont clear my 16" alpina's

[DanThe]

He said Hartges

I have the same problem, want to fit my Alpinas but the fronts need redesigning, new bracket/caliper and smaller disc. Rumour has it you need a 308mm disc to go under the Alpina wheel

Loads of pics in my thread, linked above
