Thanks for the help, i have tried to get some information from http://www.timmonsbillet.com/Porsche.html

and if he answers i will buy the adapters.


I allso have Boxter disks used, but i will have a brake reapair shop to smooth them. Is it recomended to use the Boxter or the original SC disks when changing the calipers? Does the boxter rear disks fit right on the SC?

Thanks

:confused: What does that mean? Nothing in Mahler's advice was "wrong", so he wasn't "beaten". His point was don't setup you car for too much brakes, and the added weight of big rotors/caliper that are bigger than what you need will only slow you down on the track. And he's right. Important stuff for a track/race car. If your car is just a street car, bling it out :D

The whole point here was that using Boxter calipers on Carrera rotors is no better than and a lklot more expensive than using Carera calipers on Carera rotors;)

Anybody that thinks they are going to derive some great benefit from using big calipers on small rotors is going to be sadly mistaken.

thechiller,
Do not use SC disks. They are only 20mm thick, use the 24 mm 3.2 carrera disks. You can not use boxster disks, they have a different height of 62 vs. 84mm on a 3.2 Carrera.
As said above, perhaps you get a bit more clamping power with the boxster caliper but you will not gain more heat reserve with the same disk. So unless you only run sprint races where you'll need the extra clamping power you might as well go with carrera rear caliper and save the hasle with the adapter.

Well... in my last post I actually quoted Bill. So he and I agree-- make sure you get what you need, but no more than you need.

I do not post often and I lost track of this thread because I was going racing. Yes, real racing. Not hot rod street driving, but racing. Since I race against Cup cars (996 and 997) and RSR's, and I have a homemade car, I look for eery advantage. Horsepower versus weight is a key area for me. The two worst kinds of weight are high weight, and unsprung dead weight that doesn't help my lap times.

Thanks for the help

I will use 964 calipers in front and boxter calipers rear, yes it's for because they looks nice :) bling bling. I allready have the calippers (used)

I have ordered the adapters for rear boxter calipers so they are now just to bolt on.

Ok it's recomended to use carrera disks, will these disk be just to bolt on? front and rear?

I was planing to use something like this: http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&sspagename=STRK%3AMEWA%3AIT &viewitem=&item=8047067151&rd=1&rd=1

Will these be ok, or is it a risk that the pads can fall of?


After having the engine out for the upgrade, i got some problem with the clutch. when using the clutch i get some small shaking in the engine. Like, if i drive in 2nd gear and then press in the cluch, let the engine rpm go down. when i then release the pedal the engine shake hard when it's forced up in rpm from the car speed.

So i have been recomended to change the cluch and the clutch throwout arm, does any one have any coments on this?


The car is like this today

Thanks all

Chiller, yes those rotors will work fine. Be aware the Boxster rear calipers each have 2 moveable metal pins that will need to be slightly pushed outwards to give clearance to the 24mm Carrera rotors. These pins are very tightly installed but they do move, as only friction is holding them in place. The design will not let the pads fall out.

I have no comment about the clutch judder, I am not familiar with this condition. Good luck, looks like a fine project! Go Bills, stop the Colts!! Glenn

Chiller,

24mm Carrera rotors are bolt on, both front and rear.
They are probably the best and cheapest way (along with Carrera f/r calipers) to improve your brakes. But they are not very bling because you will need a Enthusiast eye to see the diff. and they do, agreed, look tiny.
If you really want bling, go for 993tt brakes or PCCC, you will always run into somebody with bigger brakes and more bling.

24mm Carrera front rotors for use with 964 calipers that was build for a 28mm rotor - hmmmmm, not good.
Std. Boxster front rotors are 24mm so with the right adapter the front calipers should ( in theory) fit the 24mm carrera rotor. As I recall, the pad/swept area are bigger on the Boxster brakes, so you will have pad overhang which is not good.

And 24mm Carrera rear rotors used with Boxster rear calipers that was build for 20mm rotors - another hmmmmm.
Same problem with pad overhang if you choose to use SC rotors.

Remember that the adapters must fit the rotor thickness and offset.

There're no easy and cheap way to better brakes.

My advice:
Install Carrera F/R rotors and calipers and paint the calipers red.
Save the money untill you can install a prober set of big brakes along with 17" or 18" wheels.
