This a great thread. I loved my 130i and I can see you're enjoying yours even more.
I find after a track day it usually takes 2-3 days of city driving to get rid of all the brake resin and deposits off so pedal feel doesn't come back until then. I'd recommend a brake bleed before and after a track day either way, it should become part of your track setup routine.
Braided brake lines I wouldn't bother, better pads and fluid definitely.
Also a 4 point harness is a must if you want to do more track days, it's amazing how it'll hold you in and let you focus on the driving. Revolution RaceGear has them. In my wrx I replaced the seatbelt bolts with eye bolts and clipped the harness into them, it was the common way to do it. I'd assume you could do similar on the 130i. I need to do the same for the 1M.
Keep up the updates.

In fact I prefer this track over Phillip Island and I found it to be a more enjoyable and technical layout. We had the long track layout on the day.
I was able to get settled on this track much quicker than PI, although that may have been down to my fantastic instructor haha. Some observations:
1) The tyres are wearing fast (esp. rears) so I may need to consider a set of lighter wheels and grippier tyres. The temps were quite hot so the tyres were overheating much faster than at PI, which was frustrating as it seemed to always happen on my clear runs 
2) Brakes... same story as before although I was much harder on them this time. Overheated with approx. 2 clear laps and I think I may have boiled the fluid in my last session which was a bit scary... luckily it happened on one of the slower corners so no real damage done.
On a related note, I had to brake quite hard and suddenly on the road today and the pedal felt quite mushy... could that mean I have air in the system? Regardless, I'll have the brakes sorted soon enough.
3) Suspension needs to be tighter esp. under braking, and the body roll is still quite evident although not as bad as the sweeping corners at PI. Still felt scary through the chicane on the main straight... kept off the curbs because it felt like it was about to flip if I clipped them. Okay maybe not that bad but still scary haha.
4) Again, engine sounds amazing and feels awesome. Don't think I want any more power if I'm honest... I'd do more damage than good if I do!
Loved finding the limits of my current setup on this layout... my instructor was happy to let me out by myself by the second run but I didn't let him leave until the last session because I wanted to learn as much as I could  PB of the day was 1:48.0101 on my last lap, which I was pretty happy with as I was more concerned with having a drivable car for the trip back home at the end of the day rather than the fastest lap time 
Some things that my instructor suggested were track wheels and tyres, brake overhaul (Ferodo DS pads, higher rated fluid, stainless steel braided lines) and something that I thought was a bit strange - a 4 point harness. He said that it lets you feel the car better and removes the effort of having to counteract the forces whilst cornering... worth a second or two on track according to him. Research backs this up although there seems to be some controversy with running them on stock seats, no roll cage, mounting points, etc etc. |
