You probably don't really need them unless you track, but if you like them and the amount of $ isn't going to ruin your retirement plans, why not upgrade?

 

a fair question and consideration, no doubt.

but my answer would be, for the same reasons i haven't bothered to avail myself of my buddies full gt3 setup that's been lying around his garage for a few years, to properly "finish" my currently adequate ( for my needs ) - yet incomplete by most standards - rwd conversion. e.g. "it's" as good now as i'll ever "need". i have what i want/need and i don't buy parts that aren't gonna do something demonstrably tangible for me

but yeah, it's a good point, and well taken.

 

If you get it for a good price it's worth the upgrade. The 6/4 997 calipers have a better brake bias and move more to the rear.

on a different note though. Using the 996 4/4 setup with spacers and 350mm rotors is a very good affordable upgrade. I noticed a good increase in braking doing this and also has more thermal capacity for track use.

 

I will check with SG next time I am at the shop.

Track day coming up in Feb.

 

as you know, they are the best

 

Question for flewis 763. I track my car and always have brake issues with stock set up except for race pads. Are you saying you found an improvement using the stock calipers, race pads and simply using larger rotors? What rotors do you use? What spacers do you need? Are they for the caliper mounts? If so, this and some cooling ducts seems like a very inexpensive way to improve my brakes! My car is an 03.

 

yes, this is a common upgrade. You use 997 turbo rotors. I ran sebro slotted rotors. I bought aluminum flat stock and bolts and made my spacers but are available from a few places.
a larger rotor always helps with braking all else being the same. You gain leverage ehih increases braking and also heat dissipation because of more rotor area.

 

I bought my TT in '10. Thought about all the stuff I wanted to do to it before and shortly after I bought it. 6 pot front calipers was one with larger rotors, X50 IC's and turbos, lowering with coilovers, sways, lighter wheels, performance ECU mod.

What I did: lighter wheels, lowered and stiffened with coilovers, adj rear sway, took off the rear wing, it broke and I don't like the look anyway. I also removed the front diff, axles and cardon shaft. I'm happy with the quick spool of the non-X50 smaller turbos, my lighter OE 4 pot calipers will give me all the braking I need for canyon carving. I don't think I'd put the heavier 6 pots and larger rotors if someone would switch it over for free, parts and labor while I slept. I don't need the braking and don't want the added unsprung weight. Modded ECU may be nice, but I don't need to tax the stock clutch. I've had tons of fast stuff and raced to the point of burn out. To each their own, what's important to you, may not be to me.

 

Do the 997 rotors and spacers fit under stock 18" twists?

 

yes.

 

someone? asked for pics of the hoses to the calipers which i found:

 

Bigger calipers are not much trouble from a DIY standpoint and you don't need to change the MC or reservoir either.

The idea of only going bigger if you track is accurate to some extent but leaves out the fact that 100+ to 60mph times are lower with better brakes too. Stock brakes are still way better than most cars on the road but if you want/need to stop faster in all scenarios, bigger is better.

Also, painting and rebuilding a set of used may get you close to new cost.
