I am not saying that there is is a problem, I am just pointing out that you should check things like this when changing components. It would only take a minute to measure your setup and check if you will need to change pads early or not.

Digging up an old thread.....
Im fitting the same calipers to a 327mm rotor at the moment (Using a standard LX knuckle)
I will post pics when complete.

[BENN0]

I have been busy installing Nissan 4 spots to the front of my LX.
I have kept the standard Torana stub, and am using VP GTS rotors (327mm) and a custom bracket to fit the calipers.
The conversion was a peice of cake.
$100 for the calipers, $80 for the pads, $420 for the rotors and a few bucks for new bearings and caliper paint. The bracket cost me nothing as I had a guy at work convert my CAD drawing into reality.

Pic was taken before the bracket was finalised.

Finished goods rear (Almost, just need to centralise the caliper on the rotor and have the bracket coated) You can see there is a bit of clearance to the rim (17")

There has been a fair bit of work on the rotors converting the stud pattern to suit the wheels I wanted to run, but this wouldnt be required in most cases.

Even if you had the brackets made at a machine shop, the complete setup would cost around a grand (including calipers, pads, hoses, caliper rebuild kit, rotors, bracket, bearings and grease)

excellent, any idea on how much the track is increased with this set up ? looks like it clears the top control arm too.

I will still notch the control arm. It clears when the front corner is at full droop (body on jack stands) but at full lock over a bump i think it will go a little too close.
I havent measured track yet. But 17x7.5 (+4) wheel sit about 5mm within the front guards and clear the suspension arms.

So did you buy second hand VP ommodore rotor/hubs?

I bought new rotors.

I havent measured the track as yet. The front end is apart (painting, rebushing etc). When its all complete, I will measure it up and post info.
The bracket took a little bit more machining to centralise the caliper over the rotor. But nothing too major. All in all, it was a fairly cheap and simple conversion.

Definitely dragging up an old thread here.

I am aware this brake setup was initially designed for a race car application, but do you think an engineer would sign off on a modification like this for street duties? I have bought some bits & pieces to do this conversion, but now I'm wondering whether to bother as far as legalities are concerned. Cheers for any comments

I am in W.A.

Cheers,

I doubt anyone would sign off on a conversion that requires drilling of the stub axle.... but ask an engineer

[dattoman]

And the fact S14/15 are cast iron calipers... heavy

[jef]

do you still get full lock or do the calipers hit LCA

[BENN0]

Another thread dig.....

The caliper looked like they would hit the subframe (brake hose connection). So I had to cut off the protruding "ears" of the subframe and square them off. 

It has pushed the track out by around 8mm so front wheels (no flares) are becoming a bit of an issue. Clearance issues with the wheels are around the guard when the wheels are turned. Its not so much the bottom edge so trimming might not help. Wheels are a 17x7 +20 with a 215/45 tyre. Will try a smaller rolling diameter tyre to see if I can get around it.

You can leave the cross member alone and mod the caliper. I changed my calipers over to Banjo's and used the lower of the bosses on the caliper for the Banjo, and reduced the height of the boss the Banjo sits against, I also got some dome head Banjo Bolts, all sits nice. I'm running VT discs 298mm? with UPC hubs and 15x7 GTS (Pontiac) steel wheels. Caliper sitting out the front.

[BENN0]

Do you know if the UPC hubs/late model disc push the offset outward like running a pre-VT rotor?

Also do you run flares, what offset on the wheels and what tyre are you running?

[mick_in_oz]

Yes the UPC Hub and VT Disc push the track out, from memory its about 8mm per side. There really is no way using the commodore disc cant push the track out as the overall height of the disc is 83mm vs 72mm and there is little room behind the disc for it go further back, the lower arm is in the way.

 

Yes Flares, wheel dish was made to suit, I'd have to go and measure it, I went from 14x7 and 14x10 to 15x7 and 15x10, when I couldn't buy 265 50 14's for the rear any more, so made up the 15's and took the opportunity to add the big brakes.

 

The wheels are very deep dish and I had to add a touch more negative camber than expected to get them off the flare, the tyre height change caught me out a little more than expected. Front tyres are 215 60 15.

 

I can measure the offset/back-space if you need me to.

Cheers for the info. Im not running flares, so don't have much flexibility around wheel/tyre.

Thanks for the offer to measure, but I dont think it I need it. Cheers
