any body know the best brakes for four lugs that work well in our teeners and are in a decent price range? I figure I can get some used bmw calipers at a used parts yard If I knew the model and years instead of throwing down 400 bones for two bmw calipers at AA? any good knowledge out there on brakes?

I believe the early non -vented 320i E30 ones are a bolt on,easy to rebuild if you get them from a salvage yard,just make sure you get them from a car with the brake system still intact otherwise they will be rusted up,its a very common mod from way back should be heaps of info out there,cheers.

I see you are new here. Go to the Classic threads and read up on brakes. Everything you need to know is there. BMW brakes are an urban legend.

Go to NAPA and get a set of rebuilt 320i front calipers and use your old Porsche 914 calipers as cores. Pelican has the tech article in their 914 catalog section. You need to machine .060 off the caliper mounts to center the caliper over the rotor.

I don't condone this swap - though I have them on one of my cars, but here is the article: http://www.pelicanparts.com/techarticles/9...MW_calipers.htm

Machining is only required for mounting on later-model cars. I got mine for a '70 and they bolted right on. I had to do a little grinding on the calipers to clear the big wheels, however. I got mine as remans at NAPA, for a '78 320i, I believe...it was a long time ago.

Before heading down the heavy BMW caliper road, call and talk to Eric Shea @ PMB. The stock Calipers are a very good caliper the problem is that after 40 years of neglect they are not performing at 100%. With a caliper restore from PMB and an upgraded pad they will perform as well as the BMW upgrade without the weight.

Lots of effort, just to do something dumb. A proper rebuild with good pads blows this "upgrade" away... (IMG:style_emoticons/default/blink.gif)

I am very happy with the results of the BMW calipers. Our '70 has a 17mm to 19mm upgrade on the master and with the stock front calipers, the increase in pedal pressure needed to lock up the front wheels went way up. Adding the bigger piston BMW units brought back the balance and the brakes work great. I also bought these calipers as remans from a parts house fairly cheap. There wasn't anything wrong with the old calipers, they just were not a good match for the bigger master cylinder. For an inexpensive brake upgrade, I would definitely do it again.

I track my car and before I began to understand the physics behind fluid dynamics and braking systems, I had already swapped out for the BMW calipers. As you'll read, if you can already lock up the tires on the car with stock brakes, then you have all the braking power you'll ever need. Add in big, sticky slicks and the situation changes somewhat.
That being said, the only advantage I can see to having the BMW calipers, is since I am running a 4-lug setup, they are the most economical, physically larger calipers available, which in theory, translates to a bigger heat sink, HOPEFULLY keeping the fluid from boiling. I have never had any signs of brake fade, but then again, the car only does 90 down the backstretch at Sebring and I have also fabricated brake ducts to the calipers themselves and I run good quality, high-temp fluid. When I go to a larger engine in the future, I'm hoping they'll hold up, but the only way to tell is to run it. |

If you decide to go this route with all the pros & cons, make sure the calipers are ATE.

"So, moving to BMW/911 front calipers and a 19mm MC means you spent a fair amount of time, effort, and money to get something really close to stock brakes. This is why this "upgrade" is not a worthwhile idea." |

The BMW brakes are not a "dumb" idea at all. Slightly better brake effectiveness and slightly greater pad wear. Most importantly however is that you do what you want with your car. Some people thought installing fiberglass GT flares with dzus fasteners is a dumb idea but then (IMG:style_emoticons/default/WTF.gif) do they know. (IMG:style_emoticons/default/laugh.gif) If you enjoy tinkering with your car and it is something you can afford to do, go ahead with it. The great thing about the 914 is the many improvements, upgrades and just fun things to do to make it perform better and look the way you want it to look.
