Here's a link to a StopTech kit for about $3200 for our 128s:

As fas as the BMWP BBK - it certainly must be an improvement over stock. And the cracked pistons are only an issue with folks running certain pads, IIRC. Not only that, but you can easily upgrade the ceramic pistons to steel if desired ( Turner sells a kit). Not nearly as good as a real BBK, but last time I checked, they were half the price ($1500 vs. $3000). About a year ago, they were selling for $1000 - wish I had jumped on them then.

I'd say you also have a problem if you're NOT getting fade with street pads on the track!

first: I have been running them for almost 2 seasons of track events (summit point, Lime Rock, NJMP, Watkins Glen, Pocono north, ) ( 12 or 13 full track days at approx 4 or 5 sessions per day at approx 50 laps per event ) ( countless auto-x's also) Lime rock 1:06.7 The Glen 2:27.7 >> there was a full track R-comp/ rollcaged / lightned track ready 135 there also best time 2:13.2 for comparassion summit point 1:32.0 NJMP 1:22.5 Pocono North 1:07.0 times not posted to pontificate, there for comparassion and to show that i do push the car hard. I have visually inspected my pads and rotors after every event. Rotors not cracked,and they are the slotted / cross drilled (actually they are worn .5mm from there minimum thickness with theses pads on them now) Pistons and seals in PERFECT condition and original Calipers not discolored / and i suffer no uneven pad wear The car is my Daily driver.. I dont swa pads out i started on Stock ( 135 ) BMW pads that came with the kit, They got me thru Lime rock and NJMP and pocono no issues at all. I love the initial bite of the stock BMW pads for daily driving, absolutly great on the street. I then swapped to cool carbons.. I did not like theses pads.. they dusted less but pulsated at high heat / threashold points. ( i did bed them in correctly and rebedded before each event ) Now I have Ferodo 2500's WONDERFUL track pad.. can be used on the street with no issues at all ( performance wise ) , a little noisy at times, and the red dust that comes off is more annoying then the black BMW dust ) With the combo of all the upgrades in my Signature, for a 128 on the cheap you cant get any better bang for the buck. ( if you intend to go FULL RACE .. No OEM supplied stuff will work correctly as they compromise to much, but if you are in it just for the weekend warrior Time trial or HPDE...then like i said.. it cant be beat ) Also remember the 135 is almost 300+ lbs heavier then a 128 ( optioned like mine, no sunroof no nav no power seats etc ) having 135 brakes on a 128 weighing 300lbs less is a win win win win, and that is why i say they work. In addition a 135 carries about 20+ MPH down the straight into any tracks turn 1 which is usually a heavy braking zone, here also the 128 gains by actually being a bit slower, and not having to rely on the brakes alone to slow for the turn and carry speed thru the corner. also to note The BMW BBK is made by Brembo and the Calipers are Stamped Brembo, and the have a Brembo Part number. I do agree that you must take care of your equiptment.. My f30 backing plate Mod ( many threads about it ) has worked.. but for a 135 not so much. There is alot about driving style that leads to taking care of ones equiptment.. so in conclusion: I highly Recommend the BMW BBK on a 128 for spiited Canyon running / driving.. I also Recommend it for moderate to heavy weeked Time Trial / HPDE's IF you take percautions like i did. If there are any questions , feel free to ask ..

http://www.trademotion.com/partlocat...catalogid=4462 And once again, I'm not saying that it isn't better, merely that the dollar to improvement ratio isn't nearly as good as the other two options. Go to two less track events and you just made up the difference. Man we are getting side tracked, I like this thread.

For street I would just upgrade rotors and pads. Stop-tech makes 128i stock sized slotted rotors. Pads are from other sources, like cool carbon

As good as the 128 is one of the places it can benefit is in the braking dept(if the car is to be tracked). The 135 Brembos are a couple steps up from the stock 128 binders. Anyone who says the 128's are better than the 135's are seriously delusional. |

I forgot to add to my other post above..
If you go BMW BBK upgrade.. you also maintain FULL warranty and Maint coverage*** (if you stick with BMW pads)

Just because the numbers don't exist does not mean that it isn't the case. If we only believed what was written in stone than we would still think that the earth is flat. I do believe that if we were to compare apples to apples (ie a bone stock 135 vs bone stock 128 with the same driver/conditions) the 128 would in fact be the quicker car around the track. I'm not saying it would be leaps and bounds quicker but it would edge it out. |

Most track times for the ZR1/Z06 battles have the ZR1 coming out ahead of the Z06. Nurburgring(Holy Grail track for many) for one example of many. The E92 M3 is also faster than the 1M at the Ring as it is at more tracks than not. I think its safe to assume that the 135 is faster than the 128 around most tracks as well but because the 128 has so little official track times posted anywhere(leave it to you to figure out why) its all speculation, I guess.

You really have no idea what the backgrounds of some of the people in this thread are do you?

I have to agree that comparing a bone stock 128 to a bone stock 135, the 135 is quicker overall.
why.. because ive been beat by them, and drivers with similar weekend warrior experience. although i can see with the right driver (and not worring about driving the car home because its his daily driver ) i see a 128 putting up quiet a battle. I think that it can slow quicker and carry more into the corner while not sacraficing corner exit.. BUT 135 corner exit is STUPID quick as its in the correct RPM range for power. front straight speed is always 20+ mph faster .. Like i always said.. one is a better drive if one can drive a slow car fast as opposed to a fast car fast.. p.s. i usually race with my buddy in his Miata.. I enjoy following him because he NEVER brakes ( well you know what i mean ) its such a momentum car that lifting is enough.. very cool to watch .. he also beats my time every event in his S2000.... another blast to watch..

But let's agree to disagree because until more data is formed than all it is speculation. I just wanted to put 2 cents in. I actually like the 135 I just stuck with N/A because I like the smooth feeling rather than boost. Now getting back on topic, are there any good sites for parts in general for suspension. Sorry I'm a noob to the BMW world. I just bought my 1er I'm February. Y previous car was a RSX Type-S so I don't even know where to begin. My original plans were to do an all motor build but after seeing that there aren't too many parts around I got discouraged. Idk if Cams were discussed earlier but are there any available? |

from some of the statements made so far I would say the majority have minimal knowledge of brake systems and minimal experience on a track

I think it would take a very tight track with short straights for the 128i to stay close to the 135i. Or a large discrepancy in driver skill. The chassis are exactly the same, so it's not like comparing a faster car to a Miata, for example (as an aside, I did a few laps in the right seat of an instructor's Spec Miata this past spring, and it was pretty epic).
In any case, the 128i is still plenty of fun on the track. For me, that's enough. I don't have anything to try and prove versus cars that are obviously faster, except to say that you don't need to have the fastest car at an event in order to enjoy yourself. At the track days I've attended, my 128i is usually in the middle of the pack in terms of power. Until I can drive it at 10/10ths, I don't feel like I "need" a faster car - in other words, the biggest thing slowing me down at this point is me.

In any case, I still think it is a pretty good option if you can get it for the right price. It's not meant to be a dedicated track setup. Unfortunately, the current prices really are getting to be unreasonable.

And more pad surface area = more contact = more friction.. 135i discs are definitely lighter, they have less material lol Ed: and if we are only talking a front upgrade (rears still do a decent percent of the braking btw) then the bmw one is only like $1000-1200 new :/ (and <1000 used) |
