996t brake upgrade - which caliper?

[NBTBRV8]

Guys,

I am right at the point of buying a pair of new front 6 spots for my 996t. My options are to go with either the 996 GT3 brake caliper or the 997t brake caliper. So my questions are:

Given that the calipers are the same price, but the 997t pads are 50 quid cheaper per set am I better of going this way?

Was/is the 997t caliper a better piece of hardware (newer design) than the 996 GT3 caliper?

I believe both are the same for caliper spread and shouldn't affect by brake bias.

So which way should I go?

I asked on 6speedonline and they think not:

I am looking at buying the 997 turbo calipers which are the same part number from 2007 on. Will these fit under the 996t wheel?

Maybe the RS calipers are a bit bigger?

All 997 GT six pot are the same size and will fit under all o/e rims no worries.. btw the the yellow calipers are £100. cheaper than the same reds from OPC.. go figure!?..

Yes, I knew the yellows were cheeaper and I am sure Porsche know that, but that would mean that I need to change the rears to yellows too.

So where is the caliper bigger on the 997 from that was refered to earlier?

I've got the 996 GT2 6 pot calipers on the front ( part number 99635143190, 99635143290 ) with Alcon floating discs. They had to fit 15mm spacers to get the wheel to fit. It does go on and just clears the wing. Of course once spacers are on the front, you have to fit them on the back................don't you?

I'd suggest that the spacers were because of your Alcons rather than the calipers if you fitted them to a 996t.

(Very) old thread resurrection....

I've got some Porsche/Brembo 6pot calipers fitted to my car, and I'm trying to identify the part so as to get the right pads.

They're 996-351-431-30 & 432-30.

They also seem to have PGD P90 EBC Yellow pads?

Are these 996 GT3/GT2 calipers then?
What does the -30 signify at the end?

Those part numbers are for the front yellow ceramic brake calipers. So you want any 03> GT3 caliper to suit.
