Anyone know the differences between the Big Reds and Ruf brake kits for the 964 C2?

Also, where can I purchase a set of Big Reds - complete front and rear kits with everything you require for a direct bolt-on install and go on the 964 C2 in Europe at a good price?

Thanks in advance!

Ruf uses the same Brembo hats that Porsche does, as far as I know.

Try Carnewal or FVD, both should have the stuff you need.

Thanks, ilko!

Any ideas about the caliper differences (e.g. piston size, etc.) between the Ruf "BTR" brake kits and that of the Big Reds? Ruf says their kits will simply bolt-on under 17" wheels and come with everything you need (i.e. no need for master cylinder change, etc.).

big reds will also fit under 17"

in summer i use 18 in winter 17" and i have big reds.

they are in europe also expensive, even without shipping.

993 Turbo front calipers, "big reds" will fit under 17's. That's all I run, and have no clearence problems at all.

Thanks, guys.... Have just been told that the Ruf "BTR" brake kits are essentially the 965 brakes, painted black so not sure if they're worth the premium over big reds.

Anyone knows where I can get the best deal for a complete set of front and rear 993tt big reds for direct bolt-on to the 964 C2?

By the way, is it recommended to upgrade the standard fronts to 993TT big reds and move the standard 4-pot fronts to the rears? I was told the standard fronts can simply bolt-on to the rear?

No, the standard fronts dont fit the back, you need c4 rears. (or late c2 rears)

I allso am after bigger brakes, but iam trying to find a cheap option.

Bill Verburg

though you can bolt on 993tt rears you will need to give up the parking brake
because you will need custom 2 piece rotors which cannot accomodate the p/b

and yes yoy can bolt the 964 fronts to the back but that doesn't mean that they will work well for you in that position.

fotr 965 or 993 or 993RS/tt fronts the best choice for the back of a 964 is 993 rear calipers w/ stock 964 or 964RS rotors

I'm also trying to find the same. Do post if you find a cost effective solution. Cheers!

So the rear Big Reds kits available on pelicanparts and most other vendors eliminates the parking brake? Wasn't aware of that.

I wonder if this also applies for the RUF "BTR" brake kits which are based on the 965 setup?

So what I should do is to get a set of front Big Reds kit (say from pelicanparts) and matched them with standard 993 rear 4-pot calipers (which I could also purchase from pelican?) with standard 964 or 964RS discs? Do the standard 993 rear calipers bolt on directly to the '90 964 C2 without any adapters, etc.? And I guess I need a set of steel brakelines while at it.

Also, I assume I should also swap out to the 993 master cylinder?

Sorry for the many questions... very new to Porsche cars!

Why doesn't anyone offer a complete bolt-on front and rear setup for our cars, with everything one needs like master cylinder, adapters, etc?

Bill Verburg

the biggest rotor w/ parking brake that can be used on a 964 rear is the stock 299x24 or the RS 299x24 all the current BBK's w/ bigger rear rotors use 2 piece sets ups w/ hats that do not accommodate p/b, Race Technology(the NA arm of Brembo) used to custom make a bigger rotor but afaik it is nla

964t(aka 965) use a 299x28mm rotor that is incompatible w/ 964 n/b. The best you can do while still retaining the p/b is to use 993 rear calipers, this is what 964RS did.

yes, though there are several options that should be considered prior to purchasing anything

not necessarily

the 964 m/c @20.6mm is marginal for the larger pistons in these BBKs, 993 m/c @23.8 is very much prefer, besides the fluid handling capacity the bigger m/c provides a higher & harder pedal, 964RS used 25.4mm to this end.

low volume production cars get little aftermarket attention, it's just not profitable enough. The best choice for most is to emulate what the factory did w/ the RS and Cup cars of that era.

Thanks again, Bill! You're a great help!
Will start to source for a set of 993tt Big Red front brake kit (like those listed by FVD or Pelican) and a pair of 993 C2 rear calipers with 964RS discs, plus a 993 master cylinder. I read that I will need some adapters to fit the new MC and these may be purchased from 9M in the UK. Put in new Pagid Orange pads and some steel brakelines plus a full bleed using SRF and I'll be good for the track!

I have a friend with a Ruf turbo that used most the same components as the BTR. His Ruf uses the medium S4 caliper sized pads front and rear with larger pistons. It also comes with a very nice set of aluminum hats with 1" dia holes in the sides of the hats for weight reduction.

hackzi

I understand that Ruf "BTR" brake kit uses 300x25mm rear discs and retain the parking brake function. From the pictures, the Ruf kits uses 1-piece rotors versus 2-piece rotors with alloy hats.

Sorry my apologies i was mixing up the BTR with the CTR.
