Jake's Epic BMW 135i Build Thread! (5+ Years of Ownership)
-
Great garage, Jake! how friendly is that lift for very low cars? looks like driving onto boards may still be required for some
The minimum pad height is 3.5", so as long as it's that or higher, you should be fine. Fits under my lowered 135i, but I can see needing to jack it up or driving on some boards for very low cars.
For comparison, the Atlas lift I had at the shop would not go under my 135i. Very close, but needed to jack the car up first. I'm so glad it fits under the MaxJax arms without an issue.

I made it to the drag strip the other day and want to share the results! I am now one of fourĀ manual N54-powered vehicles in the 10s... in the world!
2560 DA
Log: https://datazap.me/u/suspenceful/1090-1369-mph?log=0&data=1-4Adjustments I made to the car:
- Replaced my blownĀ stock shocks withĀ Competition Engineering drag shocks for a 60s-70s Ford
- Fresh NGK 97506Ā spark plugs gapped to 0.022"
- Implemented 2-step/antilag (didn't hold RPM consistently)
- Installed a clutch slipping device (didn't work properly)
- Removed back seats and interior trunk panels (~50-100lbs)
Dragy results from the same pass:
-
Turn it up!

The picture 2nd from bottom looks like its from Forza or some video game. I dig it LOL
Saturation, clarity, vibrance:

Cool to see how accurate Dragy is.
I had always questioned the accuracy of it, but the dragy app compared to the time slip really proves how accurate it is.Ā
Impressive stuff for sure! -
Only one in the 10's still on stock diff?
Cool to see how accurate Dragy is.Ā Before smartphones were a thing I nearly bought a G-tech, there is no point now with how good phone apps are
You just made me look it up... yes, only manual in the 10's with stock diff. The other three guys all have an LSD, some with upgraded axles as well.

Yeah, Mike Heffner is his name. Super cool guy, glad he shared some pics he took with me.

Impressive stuff for sure!Yeah, it's really an awesome device. Tracks many more things in addition to the 1/4 mile as well!

Thanks Pat!
Congrats, very impressive! Any future plans to get that 60' down?
Eventually I'll get an LSD, some bias-ply slicks, etc. More practice will help too.
Congrats!
Thanks!

I removed that clutch device and returned the lines back to stock and re-bled the system. Glad I got that thing out.
After running that 10 second pass in my 135i, I was really curious what it weighed. So, I found a local weigh station and put it on the scale. I even brought my stock BMW 335i to find out the difference in weight between the two.
135i weighed 3,300lbs without a driver.
335i weighed 3,600lbs without a driver.
For more details, like the weight reduction I've already done on the 135i and how much gas each car had, check out my video below. I ripped the 135i at the beginning, so it's worth watching anyways.

Ghassan AutomotiveĀ (engine building company) is looking to sponsor their next BMW engine build. As you all know, that's one of the last pieces of the puzzle for this car. To improve my chances of getting sponsored for this build, YOU can help!

As I continue to go down the rabbit hole of weight reduction/track-inspired modifications... bucket seats were next up on the list.
With a budget of $1,000 shipped for a pair of seats and hardware to mount them, I started my search. Ideally, that price would include sliders because other people drive my car and a fixed seat would be inconvenient. IĀ didnāt want fancy, reclining seats because I'm doing this to save weight. I was tempted to go with a pair of cheap NRG seats from eBay, but decided against it. Buying the cheapest possible safety equipment doesn't seem like a good idea.
That's when I stumbled on Corbeau's website and found some attractive, affordable options. I narrowed it down to their FX1 Pro seats for $339 each and E92 (E8X/E9X) brackets with sliders for $119 each. Quality, name brand stuff totaling up to $916, just within my budget!
A few days later and I had a package waiting at home.
Out with the old...
Seat installed on bracket and buckle swapped over...
All done!
I will admit, these seats are pretty comfortable for being a race seat. If I were taking the car on a cross-country road trip, Iād prefer the stock seatsā¦ but when will I be taking this car on a cross-country road trip? Iām much happier that my body isnāt flopping around when Iām ripping around the track!
I ordered a pair ofĀ 8ā³ seatbelt extendersĀ so I could snake the belt through the seat. This allows me to buckle up within the seat instead of over the top of the seat.
Surprisingly, the stock seats weigh a massive 59.6 lbs! For comparison, the FX1 Pro and bracket weigh 27.4 lbs. Thatās a difference of 32.2 lbs, bringing the total weight loss to 64.4 lbs for the front seats. Iāll take it! I also previously removed the rear seats, which saved about 55 lbs.
Next up; a carbon fiber sunroof delete and carbon fiber door panels!
Oh wait... airbag lights...
I used theĀ ProTool appĀ byĀ BimmerGeeksĀ to get rid of these error codes. Simply connect anĀ Android tabletĀ to your car with aĀ K+DCAN cableĀ andĀ OTG adapter, open up ProTools and go to work!
