172 & Cup brakes

[RobFenn]

I understand the Cup uses Laguna brakes (front and rear or just front?), is this just discs and calipers or is there more to it? Do the laguna brakes reduce or add to weight? Also how big are the discs on both the Cup and 172.

Cheers

[geordiepaul]

I thought they both had the same brakes??

 

[RobFenn]

Ive managed to find the cups:





Brakes Front
280mm vented discs and calipers

Brakes Rear
228mm vented discs and calipers

 

[telford_mike]

They are the same. Also the ones on our Megane are the same (front).

 

[Tom]

no they aint

 

[RobFenn]

ive just found this site - http://www.renaultsport-clio-172-cup.co.uk/http://www.renaultsport-clio-172-cup.co.uk/ is it someones on here?

Still cant find 172 disc sizes..

They look the same - are they different then?

 

[Tom]

Yep my cup brochure is at home so i cant tell you the disc sizes

 

[RobFenn]

They are definetly Laguna ones at the front.

 

[telford_mike]

Or does the Laguna have 172/Cup brakes?

 

[RobFenn]

The laguna came out before the Cup..

 

[Tom]

gotta hand it to you rob you know your cars

 

[telford_mike]

Yeah but the 172 came out before the Laguna

 

[RobFenn]

But the 172 doesnt have the same brakes

 

[geordiepaul]

If you go to http://www.renault.co.ukwww.renault.co.uk and loot at the technical details of the clio you can compare the 172 and Cup, they both have the same

172 on the left and cup on the right






Front Disks (Diameter mm)
280
280


Rear Drum (Diameter mm)
228 - Rear Disks
228 - Rear Disks

 

[RobFenn]

The same same diameters might account for the Megane ones looking the same then.

Cheers Paul.

 

[RobFenn]

Now what is the lightest material you can get aftermarket brakes made out of? (fastroad use)

 

[telford_mike]

Lots of tasty looking ones in the new Demon Tweeks brochure, including discs made of a blue coloured alloy that would look stunning on a Cup. Ill have a look when I get home.

 

[RobFenn]

Thanks

I thought we settled this AGES ago.

I told people that the 172/cup/megane coupe/cabrio have the same calipers. Found out through the part #.

What DID confuse was when i also said that the cupRacers used the laguna V6 brakes as they ALSO used the laguna front struts and a heavily modifed front subframe. Later, i mentioned that the cliocup (which the team which runs a cup racer got hold of) told me that he was surprised to find that they also ran the Lag front brakes.

Which is why i wanted somebody or people to copar a cup and cup when they next met. But its without a doubt now, they all use the same.

 

[BenR]

as for lightest brakes........cerametallic or carbon compounds......but they wont be available for clios or most cars.

steel is about as light as you can get, without undue wear and the right CoF.

 

[telford_mike]

None of the manufacturers seem to want to tell you how much their discs weigh. But the really cool blue ones are Mintex C-Tech. The pads that go with them are allegedly dust-free.

 

[BenR]

Blue discs!!??

where this?

C-Tech pads are mintex 1144.....great...but deffo NOT dust free, ill show you my wheels...they are supposedly silver..lol

 

[Ozzhedian]

I know for a fact that the brakes on the cup arent the same as the 172s. The 172s come with ABS.

 

[BenR]

he stumped me!!!

im out! lol

 

[Carlouk]

Just becausee the 172 has abs and the cup hasnt doesnt mean they have different discs on them. You can have exactly the same setup without abs.

So the cup racer brakes arent completey track biased and can be used on the road then? Do you know if this set up is lighter than on the road Cups?

I thought standard road car brakes disks were made of Iron due to its thermal / friction properties etc where as steel while being lighter wasnt up to the job

 

[BenR]

its not a pure iron.......

Rob, not fully track, but brake pad compound wont suit the rd...and theya re laguna struts with laguna brakes.... alot of effort for little gain. Get teh brembo kit for the megane etc etc....

Carlouk - i was being sarcastic......i know!

mike....BLUE DISCS! surely it wears off in 2 mins???

 

[RobFenn]

Im not looking for better performance per se, priority is saving weight but thanks all the same.

Think youre right there Ben, a lot of discs give a purpley/blue hue which wears off.
