Hi
I`m looking at fitting an uno turbo rear disc set up but have 1 question,if i use uno discs and hubs won`t that mean i need different offset wheels?doesnt the hub size dictate the 45mm offset on the uno turbo?
Cheers

Basically, No.

The hub stays in the same place and the disc bolts to the hub so the mounting face for your wheel will be in the same place in relation to the body of the car. The disc has a different depth which should be matched by the caliper design. As long as the disc is not shallower and the caliper further outboard, you should have no problems, unless they are so deep they foul the arm.

Sorry for the digup but its still not 100% clear on what i need for the rear disk conversion.

If i use the Uno Turbo setup, i need the rear hubs and rear calipers, then use the front disks off my cinq?? Do i then need to make a mount for them or will they bolt straight on?

i know i need to alter the brakelines and put in some flexi pipe, just i need to know what i need to ask for/take off when im trawling through the breakers yards.

Thanks

Use the UT rear calipers discs and pads also use UT rear mounting brackets..

The last 10Cm of the brake line needs to replaced with flexy stuff...

Would only get rear discs done when using GT calipers on the front otherwise braking could be a bit interesting

See my members motors thread got them this avo So mounting brackets as is the rear hubs?

Uno rear hubs, Uno rear calipers, 227mm disks, Uno mounting plates for a straight fit.

Cento rear hubs, Uno rear calipers, 240mm (cento fronts), modified Uno mounting plates (caliper holes relocated 6.5mm outwards on the mounting plate).

As recently discovered, all conversions suffered from long pedal travel to stop. This is due to the mounting position on the centos. At Uno, the caliper mounts higher and with an angle to the horizon, at cento lower and in straight line with the wheel line. The latter mounting causes the bleeding valve to sit lower than needed to let the air escape. The solution is to bleed the caliper before mounting.

Asteris,

You saying I could use Cinq rear hubs with UT Calipers, disks and brackets?

ive got rear discs and standard front brakes (not for much longer) dont notice any problems, you can feel the back stopping more now though and the handbrake is amazing

Back end not seem to get a bit light under braking then? :devil:

not really no, u can feel it stop more on the back end though, its not hughly noticeable but you can feel the car making a more powerful stop if that makes sense

If you want to use the cinq hubs, you need a 6mm plate fitted between the hub and the disk. You'll have to custom fabricate this one, but it would probably be cheaper than a set of UT hubs.

What does it have Clearance issues on then the Suspension?

No, UT disks are 46mm fat (total), where the cinq ones are 40mm. Cinq hub is shorter that the UT by 6mm, so if you fit the UT disk to the Cinq hub, the braking sufrace of the disk will be 6mm deeper than the caliper slot. That's why you must fit a 6mm spacer between them, in order for the disk and the caliper to align.

There is another option to avoid this spacer. Take a 240mm disk (cento front) and cut it to 227mm. It then fits straight, without spacers in a cento hub (as it is 40mm wide). Some might say it is risky to cut brake disks, it weakens them and perheps they are right. I have not tried something like that, nor i suggest it. But there is a friend of mine here in greek clubcento, who cut a set of 257mm GT disks, down to 240mm, in order to fit them with UT front calipers and without using front UT hubs, similar to your case but in front. He has done more than 20.000 miles with no probs till now. Rear disks get less stress than front, so it's your choise...

Thanks for your help I fear I may have to go the expensive route and get new hubs

Yesterday i fit a set of Alfa146 rear calipers (same as Punto GT3), my ex front 240mm discs and the modified mounting plates i described in the previous page. All fitted fine and now with 257/240mm, braking is more balanced than before with 257/227, where the car used to dip at the front.

wow some set up.lol im having enough trouble fitting the gt calipers

Hi,

Are the rear brakes of a Barchetta the same as a Punto GT?
I still have my old OMP racing front 240mm disks and want to use them at the rear brakes.

I know that it isn't a straight swap but how do I get the handbrake wiring right.

you would need rear calipers as they have the handbrake fitment

As suggested, use proper rear calipers with handbrake levers, unless you are allowed hydraulic handbrakes your side of the north sea.

MIght sound silly D, but whats stopping us from having hydro handbrakes?

Assuming the system has its own fluid circuit, doesnt drive the calipers (eg: drives a spot caliper or similar) and has a ratcheting mechanism?
