K-Sport 8-pot/330mm brake upgrade for 156

Hi all

I've read various threads referring to this upgrade package including a couple of failed group buys. Has anyone actually bought the kit? I'm considering it for my 156 V6 but want some reassurance that they will fit without any problem (I have 17" GTA rims).

Any help on the clearance question along with any other feedback on this kit or alternatives greatly appreciated.

Cheers

Cheers.

I would recommend a 6-pot 330mm instead, easier to live with.

Hi Zeggi

In what way would they be easier to live with?

Cheers

Less pads, easier to find, etc.

well im runing with a similar setup...
and pads sure there are a few, but the main issue is that a 8-pot setup isn't for everyday use.
Since you need to brake much more late than with lets say OEM or 6-pot.
The calipers are in 2 different sizes, 2 big and 2 small, all of them don't push out all the way when slowing down gently so with the 8-pot setup you will have to slow down alot more late and really hard.

So for everyday use, go with a 6-pot setup instead of 8 and also i know a few people in Sweden that have tried both K-sport and D2 with heat issues and calipers not pushing out all the way etc..

as i said before im runing with a 8pot setup and im not comfirtable with having to slow down so late, what if you brake late and the brakes fade? you'r screwed thats what... happend to me once

You won't have any problems with the 8 pots.

To get the best out of them you need to brake hard and late, but thats the whole purpose of big brakes.

Hi guys

Thanks for the feedback, appreciate it.

As it stands I can get the K-Sport 330mm 8-pot kit for far less than a similar-size 6-pot kit, so even if there is some compromise I'm inclined to put up with it. Frankly it's probably overkill for a roadcar but so is too much horsepower, and I'd go for big stoppers first. I had complete brake failure at around 180 km/h some years ago and fell off the road in spectacular style, since then I've always preferred too much brakes than too little.

My main concern was - and still is - will the damn things fit behind my 17" GTA wheels?

Cheers
Rory

I think its easier if you check the specs on the OEM 330mm and compare sizes

there should be a post regarding 305 compared to 330mm i guess you could find some info there.

What style of GTA wheels are they??

I think they changed the styling when they fitted the 330's to the GTA's to get them to fit.

If you have the multi spoke version you may have problems??

I have the later GTA teledial style, which fits the OEM 330mm set-up. Alfastumper do a 330mm 6-pot upgrade for non-GTA 156s which also fits with these wheels, so indications are that the K-Sport ones should fit. But, all it would take is a few mm difference in caliper dimensions and you've got issues.

Sod it, I might just buy it and try it.

Diameter of the wheel has nothing to do with caliper clearance in this case. Only if you were talking about 16" wheels, but the from 17" upwards you will only have issues caused by the wheel design.
GTA teledials are pretty good at clearing calipers, though.

I had made the decision to take the punt and buy these, and the day I did I lost my job & all unnecessary purchases had to go on hold. Apparently, a brake upgrade is an 'unnecessary' purchase

Sadly, I'm still not working, but when I am this will be right back on the table. Keep you posted.
