what caliper is that?

[romkasponka]

E38 6 cil engine only

[Gunni]

if you can fab up a adapter strong enough then no problemo,
not sure it will cleare that wheel and run 300mm´s

I guess if you want to stick with BMW, but have you looked into the 300zx tt aluminum calipers? Nice, strong and light saving on unsprung mass. I had a set awhile ago but really contemplating on getting some used ones again to see how the measurements would line up.

[romkasponka]

these are brembo 3,2kg, ferodo DS3000 racing pads available ;)

ya, if you use the BMW calipers your unprung weight would increase. do they nake adapters for the nissan calipers for our cars?

nope. everything about that would have to be custom made.

but the price for these was 2x25$ ;)

I tried using these calipers already. too large and cumbersome that is why I did the dynalite calipers and they fit in 15" wheels. I figured no matter what the price of the calipers, if they dont work right who cares.

I'l try to fit them in 15" wheel, will see...

What do you mean by saying they dont work right?

[dino245]

What is the piston diameter. Compare this to the factory piston and then compare the increase in caliper piston area and the master cyl. piston area. I would guess that the calipers have pistons that are way bigger than what the stock master can move. I looked into these brembo calipers but the bodies and the pistons are way too large and for mee look out of proportion to the car. It would be like putting a big block chevy in a chevy sprint. This is just my opinion.

The guys in Russia just swaped and they say it works fine. I have few xls calculators for brakes and will try to make some calculations..

very nice :cool:

[ak96ss]

Nice, but the holes look mighty close together... don't they have one drilled for just a four-lug setup?

[Tonyb]

Why are you doing this by the way? I think the factory setup is fine for the street.

[318is91]

he rallys his beemer and look at his other mods they are very purposeful and well thought out for its purpose.

with the 4 pot set up, I suspect u need to step more for the brake to bite... Cos more fluid needs to be displaced to push the 4 pots.. That's what related to me by a buddy of mine running a 4 pot Nissan brakes... next up is the E38 dual diaphram servo.. Actually, the E32/38 servo conversion is one of the common upgrade here to increase brake feel but it locks up the wheels easier too, especially in the wet..

No, brake discs are from audi A3 288mm

Make sure you have the seat belt on!

?? How is the project going on?

What about theese AP racing rotors?

I like the disc! Stock, but definately more effective. Ferrodo... They start braking a while after You stap on the brake pedal - as they get warm enough... Nice setup :)

OOPS... I meant "PCV"

Any benefits from this?
