Stoptech Brakes

I am running R33 Brembo rears!

Just thought I'd give an update.

I ended up going with my first choice of brakes, which was CSC. I'd always said that was the setup I was going to go with once I decided to upgrade, and thanks to a lot of help from Stuart at Benson Motorsport (t01-100 on here) I picked these up last night.

So now the brake setup is CSC 4 pots with 343mm discs, 33 GT-R rear brembo calipers, and a BM44 Master Cylinder with the ABS blanked out, set up for use with no booster. Should be plenty for my lil' old 180SX

Phunky, these fitted yet? How you going with them?

troy, can you remember if the biots i bought for marcus were curved vane? they were certainly sexy and exy enough. lol.

Ahhhh, so we're in the same boat then...

So you don't think something like RDA's would be suitable for the back?

Nick: Nah mate, not yet. Waiting on rear rotors, lines and front brackets and lines... oh, and the car to have an engine in it

[Roy]

I cracked an RDA rear rotor at Calder last year, was kind of scary until i caught on what was going. I didnt get the pulsing in the brake pedal like when i cracked the fronts...so took me a few laps to suss out what was going. On, my thoughts are basically RDA and DBA are all crap if you use your car semi regularly at the track with anything resembling a racey pad with good torque characteristics

[phunky_monkey]

Dang, well that sucks! Back to the drawing board...

[R32gts-t]

brake kit looks mint dane!

good to see some good progress, so, piarc in november?

[phunky_monkey]

Hopefully! I'm shooting for the Sandown Maserati day in October, so got lots of things to do. Picked up a bunch of paint yesterday, so should be getting the sound deadening out and spraying the interior tomorrow, and starting prepping the rear brembo's for paint yesterday. Then it's a rewire, get the tailshaft made, and piece the thing back together

[R32gts-t]

exciting times!

hope it all pieces together smoothly for you...

it must feel good to be close to steering again,

the car is going to be so different!

[phunky_monkey]

Finally there's a light at the end of the tunnel.

Thanks man. My car never goes smoothly though... never

S14 Stoptech big brake kit, Enkei 17" wheel just clears the inner part of the rim, outer clearance from the spokes is fine. Caliper takes common sized Porsche pads.

It's amazing what brakes you can fit with the right adapters and hats.

A mate of mine is running Porsche GT3 front calipers and 993 twin turbo discs on an old 911 under factory 16" porsche rims.

Here's a photo of his front brake setup ...

Details are here ...

Here's a photo of his car with the 17" road wheels he uses. His track rims are factory 16 inch wheels.

He got a custom set of caliper adapters made up and a custom set of hats.

The key is proper measurement of everything - he's a semi retired engineer & was very careful on his clearances.

If you run the caliper too close to the rim, it can get nasty - I saw a touring car rim a few weeks ago where a stone got stuck between the rim and the caliper. With the rim spinning the stone machined a groove right round the inside of the rim. It could have easily have cut the rim in half.

Adam, any idea of delivery and price? I am waiting on a delivery price and was expecting to pay for them on Monday (from the US)

I woudl love to buy them locally but V-Sport seem to want an unusually high amount for them. I appreciate businesses have over heads, but they are some 65% more expensive.

Adam, what size is the rotor and how many pots on the caliper on the Enkei?

Adam, what size is the rotor and how many pots on the caliper on the Enkei?

The front rotors on the supercharged 911 project car are factory Porsche 993 twin turbo rotors running on a custom hat. They are 322 mm x 32 mm.

It runs Factory Porsche GT3 calipers on the front on custom caliper adapters. The GT3 calipers are a 4 piston caliper with a pad area of roughly 153 square cm per caliper. Here's a pic of the supercharged 911's brake setup ...

Bear in mind that the weight of the supercharged 911 with a full fuel tank, no passenger seat and no spare wheel is just 1124 kg, so this is truly a mammoth brake setup on such a light car.

It's hugely impressive that Ray (the engineer who owns the car) was able to squeeze such big brakes under factory 16 inch wheels, particular since 1970's Porsche factory wheels were never designed with such big brakes in mind and they don't have the very square inner profile like many more modern rims do.

As for the Enkei pic, I didn't post that pic - I just replied to that post it was psoted by 260DET. Here is his post ...

Hi Duncan,

Are you talking about the Porsche GT3 calipers there ?

What size disks are you running the calipers on ?

OK. Anyone out there actually running Stoptech brakes? Please PM me if youy are. I'm having problems getting piston sizes from ST and can't determine what BMC size to match their R32 GTR kits to. They are very coy about this information, which really leaves me unable to make a decision.

Any suggestions? Anyone know this info?

[Mr. Keets]

Nick, try the GTR UK site. There are quite a few guys there who have gone Stoptec
