Big Brake Modification

[markgq4]

bloody hell!
that caliper looks MASSIVE !!



or perhaps you have little, tiny little feet ?

he is nearly 2m tall and his feet are size 47 i think ( he gets paddles to go whit the boats of the shoes)

Has anybody bought or installed this:

I was going to implement the 166 calipers solution for the front brakes but..

a. here the calipers 166 calipers are rare and will cost me $750.00
b. you cant get the fiat coupe vt20 disks here
c. I need to keep wheel size to 16" and I don't think I can get wheels that I am SURE will fit...

so at $2000 the complete 6 pot solution from D2 that includes disk rotors, calipers, brake lines and even pads looks cheaper and more certain.

what do you all think? I'd rather not be the first guinea pig!

[RMB-Racing]

Well Jim...

From you point of view, I can see that you have some reasonable arguments to buy the kit.

Here in Europe, its not a problem for us to get all the bits to make our own kits with the calipers from 166 or Coupe 20VT.

But with you problems as you referred too, I would go for the kit!

By the way - have you checked the FIA homolegation for the 155 Q4 - is it allowed to have six pots caliper on the car...? (if you are going to use it as a racecar)

[jimnielsen]

They don't bother too much with the niceties of FIA documentation over here.. Brakes are essentially "free" except no carbon disks....

Maybe we could do a group buy on these?
As 286 fits in the 16 inch wheels?
Depending on price i could be tempted.

[wrinx]

My plan was to use Wilwoods inside the Zender Milanos I've got as the 166 calipers will have to go

Or you could just sell me the Milanos, and problem is gone..

[wrinx]

Yes, I see that could be a possible solution....mmmm, let me think about it.....





...NO!

Ok when we tried to mount the calipers we noticed that the brake pad "looks" over the brake disc for a few mm!So the braking effect is not 100% plus its thougher to find a set of 16" rims that fit becouse the calipers stick out too much(they stick out up too much not out ).

We are going to try it to solve this in a way...

[Gery83]

Hi!

Does any of you guys changed the master cylinder too, or you use the original one?

[AlfaJack]

Not heard of anyone upgrading so far...

[Gery83]

Thanks!

[jimnielsen]

Can someone who is familiar with the brake upgrades that involves using the fiat 20V front disks have a look at picture and tell me if these are the correct ones to use? Do the measurements look correct - I am expecting that they will be just a "bolt-on"?? I am planning on using Wilwood calipers so that they will fit inside my 16" speedline wheels with these disk rotors. Feedback appreciated!

jimn~

[wrinx]

Yup, them's the ones, 20v turbo 305mm discs

...and yes, they bolt straight on. I'm also thinking about Wilwoods so am interested in how you go on and which ones you choose. Looked like it was going to be very tight inside the Milanos I've got.

[jimnielsen]

I am not married to the idea of the Wilwood's but I need a caliper that will suit this rotor that is light and physically smaller than the massive 166 type brembos. That way I can continue to use 16" wheels and tyres that are 590mm dia (in 205/45/16R).

Any suggestions about specific calipers appreciated - or even just model of wilwood - there seems to be so many...


jimn~

[wrinx]

I was looking at Dynalites iirc, but for 17" wheels...I was also thinking of using the standard 280 discs...think you may struggle to get both 305 discs and Wilwoods under Speedlines???

All measurements are on their website

[jimnielsen]

Wrinx - how did you adapt the 100pcd onto the Q4?

.....

There's a full secondhand set on ebay now HERE

...and THIS is like the set I bought, although I've got 100pcd

wrinx

.....

[wrinx]

Wobble bolts.

Some people don't like them but I haven't had any problems.

wrinx

[jimnielsen]

any chance of a pic or diagram that shows how you used them? I am going to have to use 4 x 100 rims as well...

[AlfaJack]

Got the pic from this thread on AO (also and Aussie with a 155, he seems to know your car):

[wrinx]

Strange bolts, the cup is loose fitting one side but the top appears to locate in a centre cup which would prevent them from moving properly???

The ones I have don't have the lip around the bolt, allowing it to move freely.

wrinx

[jimnielsen]

Thanks Alfajack! - I'll enquire with him directly! Thanks for taking the trouble to post the pic.. now i can believe they actually exist!

The ones in the pic are the same as mine. The lip bit just seems to stop the wobbly bit falling off the bolt...

jimnielsen:

If you would like to fit spacers(let say 20mm) with 4x100 wheels then the problem starts
