BBK for e30 318/325s, e30 M3s and e36 M3s

[Massive Lee]

I just emailed you another question, can you attach that PDF (4-pot) when you reply (david.moffitt@ .... )

PS - any real reason to want bigger than .81 for AutoX / Street only? (I have another car for the track)

As I may have mentionned earlier, the kits are intended for racing or drivers schools. Even though I have produced .81" kits in the past, I elected to stick with the heavy duty stuff. Thicker rotors will dissipate heat much faster. Obviously, they are more difficult to fit as space is usually at a premium with the e30 wheels. But usually, track junkies will buy their wheels around their brakes.

Hi Mike.

Please email me either at l.vuong@sympatico.ca or massivebrakes@gmail.com and I will reply with the mock-ups.

BTW here are a few shots of the rear e30 M3 disc, along the original rear one.

This is racing stuff. No ebrake. A street rear kit with ebrake will be produced over the winter.

I'm very interested, I'll be eager to hear how the e30 street kit turns out as my current car is still my daily driver.

The street kit uses the same caliper (only not as wide) and same disc diameter. Instead of being 1.25" thick, the rotor is 0.81". The difference in fitting is that the caliper, being thinner, is recessed in the wheel by (1.25" - 0.81") 0.44" of roughly 11mm.

It makes fitting a bit more easier but do not expect to fit any wheel. Anyway, stock ATE calipers are okay for all around driving (the Girling calipers are shit, whatever you use them for) and my kit aims mostly at the race crowd.

Do you have pdf files for both the race kit and the street kit? If so I'd love to see them, fidhle -at- yahoo -dot- com. I'm used to a very different brake feel from the other cars I've driven and I will be racing my e30 more starting next spring so I am very intrgued with your setup. I thought I'd have to swap to a five lug system to get the type of brake system I had in mind but with your system that wouldn't be needed.

Check your emails. I forwarded you the two mock-ups: 0.81" and 1.25" discs.

BTW Swapping to a five lug suspension to get the e30 M3 or e36 325 brakes is only a temporary cure. You will like the improvement at first, until you hit the limit of the brakes. Sliding calipers are flawed: the principle of the sliding caliper calls for flex by design. And the more the pad is worn, the worst it gets. Which is why there is no better than a fixed caliper. The pedal feeel is also better as the pistons are always a hairline away from grabbing the disc, unlike a sliding one where you must eliminate the initial distance caused by the flex before grabbing the disc.

I run an e30 M3. Brakes are always initially great. Then get worst when brakes get hot, or pad gets worn.

Im really interested in these kits. The car I would be using these on is going to be a street/track car. Ill be driving the car alot on the street and every now and again on the track. From what I am gathering, you would not reccomend using the front kit for street use? Or just the rear kit?

Wonder if these are a no-go with the et25 16x7" RXs...

Also, are the rotors easily aquired?

[browntown]

someone with kopi's has to fit them, if they fit without spacers on Kopi's, there'll be a line to purchase.

it's probably been mentioned already but how thick are the brackets?

Hi Josh.

Currently I do not have rear kits for e30 318s and 325s, only for the e30 M3. The thicker 1.25" rotor can be difficult to fit on most 15" wheels, and even some 16" ones. Which is why I may resume production of the street kit with 0.81" thickness and 11.75" diameter (up from the stock 10.15" diameter).

If you use your car as a daily driver and DE car, then the street kit (0.81" discs) would be okay. I have the pdf mock-up for that street kit. Email me and I will forward you the file to test against your wheel.

I tested a street kit a few years ago on my 16" x 7.5" Hartge wheels with et25, and it required on a 3mm spacer. But because all brands of wheels have different inner dish shapes, I can only recommand to test any wheel with a mock-up that I can supply by email.

Hi double-tony.

The adapter brackets are 5/16" stainless steel. The distances beween the strut's ear and the caliper's ears are very short. The caliper will brake in two before your start even bending the bracket. On my 2002 racecar, the brackets are 1/4" thick. They never moved.

Great! My email is bimmerdrivin1@yahoo.com

Like I said before, I do quite a bit of performance driving on the street. I am the local CCA event coordinator so I do ALOT of driving year round and am looking for a better brake system for the E30. Did I miss when you said you would have the street version ready to go? Will the price be the same for the street kit? I assume after its all said and done, the total price with everything will be anywhere from $850 to $1100 depedning on options? Ill be running 16x7.5 all the way around on my car. Im interested to see the mock up.

Hi Josh. The e30 325 is an awesone car but has a major flaw: lousy brakes. I went from Girling to Ate calipers on my H23 and found only a marginal improvement. When you install a better brake system, you usually ask yourself how you could even drive the car before on a track. I used to bleed my brakes every two sessions.

The street kit might be $50 more as the hats are deeper and require more material and time to machine. Calipers are about $120/$125 each, rotors are dirt cheap at about $25 each, pads depend of what you prefer. From $70 to $140.

So, basically, you get the kit for under $950.

I will do the front street kit if I can have 6 orders which is my minimum order with the CNC shop. I already have a few sets of race kits in stock. Check your emails for mock-ups.
