E46 M3 track slag turned around in a day

[billyboysm3]

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.

Let me know also If less Or more on faster laps

Also Be interesting to compare against top
Speed and corner speed v 1A and 1B road tyres to see
Where the gains are.

Think it was 65metres shorter than the 2.99 miles.

Last time on dunlops front wishbone gone, track less grip than Monday, Only got data for one session from iPhone which wasn't best.

Either tracks got grippier or I'm now smooooother with the car.

Nice bit of camber

Love these next two pictures, under the bridge about to hit kerbs on the left.


Nicely loaded up


Ready for Nelson, camera man got me in the air.

I've ordered some 10j rims for square set up to fill the rear arches.

I have owned the car for over two + years, my aim was to build a car quicker than my previous CSL round a track.
I have acheived this over these two + years, started with a nice low millage manual example.
I drove to Scotland and back as it had to be right. 5 hours each way.
Car has been meticulously maintained, serviced every 2 trackdays, had new plugs, alternator, coilpacks, battery, steering arms,
Mishimoto rad and electric fan, OEM wishbones, every bush has been replaced with powerflex yellow along with the dreaded subframe with redish plates and resin injected in by Bartletts. At the same time they changed the brake fluid and rear brake lines.
To make the car a proven weapon on track I have added these upgrades, it was all about corner speed and getting on the power early.

AP Calipers front and rear with brand new RS29 front pads (1 TD old) and rear pads (2 TD old).
Brand New performance friction front discs.

Weighing in a 1355kg last time with nearly half a tank.
Since then had new Team Dynamics rims, Carbon airbox fitted and
Supersprint lightweight race back box, so with 1/4 maybe around 1335kg, easy.
Car is very clean inside and out. Body work bar a few places with some surface/rust bubbles on
front wings and rear as you would expect with age.
I have not painted these as id rather you see it as it is.
I have video’s of my progress and a build thread.
Price £21,500. You could not build this car for that in 2nd hand parts.
This car needs nothing. Great for euro trips, driving to work and out performing other M3’s.
Anyone that has been on track with me will know this car is setup superbly at no expense spaired.
I managed a 2.07 at Snetterton a couple of weeks ago.
