As always I love the videos and good driving 
About the brakes. Consider brake ducts and possibly an F30 335i front swap. Cheap and very effective. |
Under $15k for a used 135i plus around $10k for the mentioned upgrades…and you have a great dual-duty car that is still very comfortable for daily use and can drive for long periods on road trips with lots of cargo!
And if I had a 1M, I think I would keep it stock. I probably wouldn’t want to change its nature in any way! The handling seems perfect - both fast and loose. If I owned both cars, the 135i would become the faster car on the track for sure.
Thanks!
I have tried brake ducts, but it only allows me to run a little longer before the heavy brake fade settles in. It seems rotor size is too limited and too small to begin with. The brake ducts are also a pain to drive with on the street.

I echo the rear bar comment. For some reason that seems to be a mod few try around here. Another option is to re-adjust the sprint rates. Most of the kits are a bit to heavily sprung in the front versus rear. OP what are your current spring rates?
He is also a professional driver 
It's always weird to me that people think its surprising that a 135i with a few mods can perform the same or better than a 1M. Would it surprise people if a modified naturally aspirated FWD civic does so too?? |
Current spring rates are 392lbs/in front and 672lbs/in rear.
There does seem to be a common misconception that a tune and/or wider fenders are necessary to keep up with the 1M at the track. I made the video to help dispel that.
If that said civic was still pretty comfortable to drive and you can fit 4 wheels & tires, 2 suitcases, 2 golf bags, a cooler, and a passenger…all inside the car? Yes, it would surprise me!
The 1er is special!
