other models brakes fit?

^ beware... lug pattern may be the same but hat height may be very very different. look at the leganxa rotors... the rears have a HUGE hat hieght on them

Yeah, I didnt think it was that easy.

How would you figure out the hat height?

i used the tenzo r rotors for an acura integra and built my own brakets.. like they said. but it wasnt easy the first time i tried to build the brackets i faild horribly.. the rotor would rub on the caliper when braking. so i tried again.. and i made some that worked but i was worried about strength so i made them again with thicker meterials.. they are amazingly touchy now.. it will put you in the windsheild if your not wearing a seat belt

i would help you out with this one but i dont have a clue what a forenza rotor looks like nor do i have access to one.. they dont sell they around here

The Saab calipers are a direct fitment... the rotors need to be redrilled to a 4 bolt pattern because the Saab's use a 5 bolt pattern with a different hub spacing.

So..... cut some new holes for the 4 bolt pattern, get a hubcentric ring machined to adapt them and your off to the races.

The Saab shares an Opel platform with the Vectra.... but obviously the Saab rotors are easier to purchase.

Some of the Astra MKII guys use Willwood brake kits..... I was going to contact them this spring and check their application (as I found a "kadett" on their list but it might be for the older 60's Kadett sold in the USA)

Still though, ANY saab rotors and calipers?

How will I know what size hubcentric ring I need made? I could easily take the saab rotors and stock forenza rotors to a shop if thats what I need to do since I have extra forenza rotors.

I think it was the Saab 9-3 and 9-5 rotors which have a 5 X 100mm pattern and a hub center of 65.1 ( vs 56.6 for the daewoo )

It's been a while since I found out about this..... so my memory isn't great..... perhaps the calipers were from the Saab 900.

You could go down and grab a saab rotor and caliper and then return them after you've checked fitment ( I did this with some integra rotors )

Ok..... here is a good place to start.... http://www.cardomain.com/ride/305222

This was a 1992 Astra F which is nearly identical to the Astra E which is the same chassis as the Lanos.

He used....

Front: Saab 9-3 Turbo (290 mm discs and calipers) 5x110 hubs from Saab 9-3
Rear: Saab 900 Turbo (standard Gsi calipers) 5x110 hubs from Saab 900

So I guess it's mishmash of Saab 9-3 and 900 parts.

Now.... I do know this works for the Lanos/Nubira/Lemans but I'm not sure about the Optra/Forenza.... I haven't actually tried it yet.

I think I cross referenced the part numbers for the Optra calipers and they came out the same as the Saab 9-3 calipers.

I also think it might be possible that the Optra front/rear disk brakes might work on a Lanos/Lemans.... but I won't know until I try it with my Lemans
I know there are big brake Saab kits.... all the way up to something like 310mm

Unfortunatly..... without having all the parts and trying it out..... there is no way to know for sure.

Personally..... I still want to go with a Willwood kit.... but I have to wait for my Drag racing rims/slicks to arrive so I can measure the inner diameter to determine how big I can go.

that is the big one.. if you go a to a 12" rotor your rim has to be at least 17"

with my 16" rims it is scary.. there isnt more then 5mm between the caliper and the rim.. if something happend where the caliper sliped those 5mm it would hit the spokes and i dont even want to think about what would happen...

i had a hunch...

since the zuki-woos have different lug patterns than the lanos and such... i figured why not start with a car that has the same lug pattern...

and thus we have the S13 (200sx silvia)

go measure and see if you're close... it's a start for sure

Audacityracing - What year is the Nissan 200 SX brakes is that?

Also heres Bremo product catalog:

http://www.brembo.com/NR/rdonlyres/BEF3 ... es2006.pdf

It has the mesurements of the brakes, which should be helpfull.

Sweet. Is this is MM?

Here is the measurments of the stock front rotor in CMs. If 10mm equals 1cm then I converted it.

A-25 1/2 (maybe 3/5ths) *255-257mm*
B-
dop-
d1-6 *60mm*
d2-n/a
h-5 *50mm*
c- 11 1/2 approx. *115mm*
ports-4 + one for a screw to hold it in place but isnt needed
E-approx 1 1/4 *12-13mm*
I dont know exactly what measurment B is and what DOP is?

lol... did you miss it twice?

damn i'm blind, sorry

yes... that's mm. the b and dop readings are from the top of the hat to the disc surface
