Default brake options 3.0,16 turbo

Looking for some advise. Currently building new 3.0 16, turbo 968 and I am looking at brake options. The car will also be used for track days but will not be race car light I’m guessing slightly lighter than standard. I estimate 450 -500 bhp. My 951 track car which weighs 1100kg and runs about 350bhp has the Lindsey big reds with 993 turbo disk conversion and fast road/ track pads. They are all that the brakes that car needs a perfect match.
The 968 will be heavier and have more hp. Will they still be adequate or do I need to look at a bigger disk and caliper? I also have a set of standard 4 pots off a 996 turbo how do they compare to the big reds can anybody tell me the piston sizes for any of these calipers and also the 996/7 six pot calipers off the the gt3,s etc

I'm building a similar car and I think the Big Reds will handle it pretty well. A bit of ducting to help clear the heat between braking zones is always of benefit. Your 996TT brakes should match up nicely.

Do you know if the 996 4 pots are as good as the 993 big reds. I know you can run 350 mm disks with an adapter bracket for the calipers

I've run 996 Turbo/GT3 calipers with 330mm Cayenne rotors on my track car for a few years, LS2 engine as of last season, so 400ish hp/tq. No complaints from me, and they really fill up the 18" rims so your friends at the track won't make fun of you for having tiny looking brakes

Car looks good, food for thought.

Big Reds are more than adequate. With the 996 setup and 350mm rotors you are just adding more weight.

This is my concern ( weight). When you say big reds do you mean the 996 4 pots or the 993 big reds

993 Big Reds. The 996 discs are huge and heavy and this is unsprung weight. If the 993 brakes can do the job which they can then why add more weight.

Agreed. That has saved me a lot of money.

Geez, you are completely missing the point of 951 ownership

If you're running downforce and slicks, Big Reds are marginal at best. They were groovy twenty years ago, but technology has moved on.

That's probably the worst part about using a 17Z/18Z. So many are fakes.

Also, if the adapters are threaded AL, I would consider a through bolt instead, or steel adapter. AL threads often pull out on adapters.

What is more important piston size or brake pad area.

We ran Big Reds on the road/track car for quite a while and they were fine. Once the car started getting a bit too fast (ie racecar with 500hp+ and downforce) we upgraded. I'd say you'll be on the edge depending on certain factors. Ventilation, pads, fluid, duration on track, how many really heavy braking zones on your local track/s.

That’s where I think I am. They will be fine for the road but maybe on the limit on the track. I guess I should just try the big reds as I have them and change at a later date if they are inadequate.
