Car in question:




That car has been running stock /4 brakes for how many years? WTF?


(IMG:style_emoticons/default/agree.gif) What he said.

Genuine BBS LM wheels at those sizes, with what I am guessing is a powerful V8, but steel 914-4 calipers?

Time for an upgrade, and with that kind of power I'd be looking at some sort of 4- or even 6- piston setup up front and four pistons at the rear. With a footprint like that, it's definitely worth the best wheel bearings you can get, as well. The 993 GT2 ran wide 18s and was at the limits of its front bearings...and those were the much larger 964/993 concept. Then again, at least the 914 is a fair bit lighter, and I doubt you are running slicks at race speeds for 12 or 24 hours.

Holy Crap Trevor, what a crazy 914! Great job Engineering that Beast!
You shouldn't have any problems figuring out bigger brakes...


Haha thank you and yeah I won’t have a problem but I like to look at it from all different angles (IMG:style_emoticons/default/beerchug.gif)

I have been running this setup for over a year now and had no problems at all my setup is huge and my rear tires are 335 r888 so this is why I’m looking for a good break setup. Before this car was just for cruising and shows. Mow I’m looking to get into autox and some road racing.

Yeah did everything but breaks last because it was just a weekend warrior but now I want to race and I do plan to run a 6/4 set up mainly looking at willwoods

Trying to save some coin and time.


I have Boxster calipers on all 4 corners.
Best brakes i ever had on the 914 and trust me, i tried a lot of different setups.
The adapters as well as the calipers are readily available.


I'm not sure how reinventing the wheel fits into "saving money and time". There are already plenty of options out there and a good portion of those are (still) affordable.

On 15” wheels? And what about the e brake?

Or a 914-6 rear caliper. Rotors could be re-drilled to 4 lug.


(IMG:style_emoticons/default/agree.gif)

But still a boat anchor. Of course, then there's the trailing arm...

It surprises me that no one has done an Elephant Racing style trailing arm for the 914, one with better mounts, better adjustments, and less weight. Between that and the caliper, I wonder how much unsprung weight might be lost in the rear alone. Which raises the question of how much weight might be saved up front with the GT3-style system now available, as well. There's a lot of steel in the 914's suspension. It works, but...

If we are adding lightness into the equation, the 914 trailing arm only weighs a couple pounds. It just looks chunky. Eric Shea/PMB made an aluminum 914-6 caliper. It only got a luke warm reception (914 guys are cheap) but weighs half the steel caliper. I'm sure you could track down a pair. Go with the alloy 3' Brembo caliper on the front (3" struts are lighter than 3.5) the 911 alloy crossmember and you have a killer lightweight big brake setup that bolts on.

(IMG:style_emoticons/default/happy11.gif) (IMG:style_emoticons/default/agree.gif)

Anyone have a set of the rear alloy calipers they want to sell? I have the fronts down.

When Eric came out with the alloy rears, I was finding rear Ferrari 308 calipers for $250-400 a pair and sending to Eric got the GT conversion. That supply dried up and Eric got tired of selling the alloys near cost. (IMG:style_emoticons/default/sad.gif)
Even the alloy brembo fronts have gone up a lot.

My idea of the ultimate 914 brake/suspension setup.


911 GT3 front suspension with coilover shocks and Boxster Brakes

(IMG:http://www.914world.com/bbs2/uploads_offsite/www.elephantracing.com-1143-1539108861.1.png)

Boxster rear suspension complete with brake calipers.

(IMG:http://www.914world.com/bbs2/uploads_offsite/image.superstreetonline.com-1143-1539108861.2.jpg)

Go full race bushings on the Boxster rear suspension.


Very adjustable and capable of handling a lot of HP.


Very cool idea, Clay—and GT3 Cup control arms are a direct bolt in for the rear, which offer a lot of precision with more than enough compliance to be nice on the street.

Raise the upper damper mounts for the rear with custom coil-overs and...that would be a very trick setup. And there are a fair number of dead 986s out there. For the very adventurous out there, the GT4 stuff is even nicer....and set up to work with a gearbox with a limited slip diff, axles, and gears good for 385 hp with 300+ lb-ft of torque in a 3000+lb car with sticky 295s out back. If all could be adapted, it might be the ultimate setup for a 914 with a lot of engine. Might have to "downgrade" the brakes, however, as everything is set up for 20-inch wheels. 19s fit over the standard GT4 brakes; 18s are trickier with the knuckles...making the 986 (which used 16s) or 987 era (with 17s) a better fit.



I am seriously considering this after I get the 4.0 and cayman 6 speed in my car. Then I can use stock cayman trans mounts!

Ok sorry I should have been more descriptive of my build I have a 914 group5 wide body with a Chevy v8 and I also have a 5x114.3 bolt pattern and my wheels are BBS LMs 18x11 front 18x14 rear. As soon as I figure out how to post pictures I will. If anyone has Instagram my name is @anigav_480

Thanks for all the replies

Car in question:



That bolt pattern could be a blessing or a curse being a common Ford pattern.


On the plus side tons of big brake kits for Mustangs so the aluminum hats are available however the rotor offset might be funky. You will also have to deal with the hubs being so large in diameter, I ran into this when I did a 4x100 conversion on 914 years ago.

I would research what people have done with earlier 911s and contact Wilwood or Patrick motosports.

Might have to piece something together, but see below for some ideas.

I was going to say mine work well, but now that we’ve seen the car, you need something like PMB is coming out with. Mine is Ferrari 308/Alfa alloy fronts, and PMB alloy 914-6 rears.

The new PMB calipers, without the other things you’ll need to install them, will be in the neighborhood of $3500.00. But you’ll by god stop! Even that monster! Which looks pretty trick by the way... (IMG:style_emoticons/default/evilgrin.gif)

As cool as those new calipers look, the rotors are way too small for those 18" wheels.

They're radial mounted so you may be able to change the adapter size and bolt em up to the Carrera 24mm rotors. Other rotors with increased diameter are questionable so you might have to go to a full on 918 setup! (IMG:style_emoticons/default/happy11.gif)

Lots of cars are 5x114. In particular the Nissan 350z/370z. Lots of big brakes there. Caliper spacing is 4" but you would need brackets to clear 12" rotors anyways. They also mount outside the hub, so cutting the rotors off stock hubs might work out with spacing.
