E46 M3 track slag turned around in a day

[billyboysm3]

Update
So since last couple of track days, steering and braking was all over the place. With new wishbones and discs and pads car was so nicely balanced today at Snetterton.

Before today I decided to buy one of these


I've been using my iPhone on and off and go pro and I never seem to record the right bits.

Sorted out some decent camber again.

Before today I wanted to work on a couple of places at snettetton to maintain speed, first was riches and the other was at coram. I thought that of I can just dab the brakes into riches and turn in hard like karting i can maintain a high apex speed.

I never seem to have perfect conditions, was losing the front end at riches all the time.
Outside temp was 15• and just could get heat into the slicks.

I ran wide into the grass a couple of times at near 100mph.

Also from the bridge to the back straight as little brake as possible and virtual flat out through bomb hole and coram. Coram was 100+ in 5th gear for me.

I got to follow John round today, his driving is now bang on the money, was able to keep me honest. All the seat time has paid off. Also what's cool is that these are both road legal and normal looking cars.

I smashed the 2.09 barrier loads, lapping 2.10-2.13 in traffic, and 2.15 -2.16 in heavy traffic.

I reckon on a day with sunshine a 2.06 is do able, I had it flashing up but never had a clear run, very few clear laps.

First session of the day and hit it.

Racestudio says if I wasn't such a pussy my best that day if I hooked it up was so so close to a 2.06



It flashed up a few times, so maybe next time.

So far any of you geeks out there.

Here is a video from RaceStudio from Snetterton comparing a 2.07.781 v a 2.09.378

Stock engine BMW M with airbox, Intrax 1k2, AP's, 4.1 diff. Car weights 1355kg with half tank of fuel, no driver.

Video show's two laps, a 2.07.781 v a 2.09.378 at Snetterton 300

The pink is the quicker lap followed by the black.
The blue on the track shows where I was quicker on previous laps.
The red is where I aced it.

So 5 corners to work on.

The 2.09 was following John in traffic. Epic driving.
You can see on the right that I had no clear laps.

Looks like the lap was achieved from as early on as the first hairpin.

Outside temp was 15*, track temp was cold and could not get heat into the tyres.

My theoretical best with this data was a 2.07.057, so close to a very late 2.06. Easy said than done.

Im in 3rd gear on the hairpins and 4th gear on Hamilton, Palmer and Williams, and 5th round Riches and Coram so not thrashing the car keeping it nice and balanced.

Does it give the lap distance in metres for each of those two laps to see if you took a better line with more or less distance ??

For those two laps the slower 2.09 one was 1 ft longer. So similar lines but most time made up breaking under bridge and from bomb hole.

What was the distance out of interest?
