To get the Marham trackdayers into the mood, I thought I’d start a discussion about the ideal line around the whole circuit - I don’t think it’s been done before.
The line I’ve described works for me with 100bhp and FWD, but I’m sure the faster guys will have other opinions. So come on, let’s have it!!!


For ease I’ve written it like a guide. The track layout will look familiar to the regulars but hopefully any newcomers will be able to follow.
I've had to make up some names for parts of the track. On the diagrams cones are marked by orange lines.




Corner 1
Starts straight away at the exit from the paddock, but you're on the wrong line. First time around fast cars will merge from a blind complex on your left.
The corner is very long and wide and the apex is right at the end, out of sight to start with. The right line will have you out to the edge of the track, then back in to clip the apex on the left. Follow an imaginary constant curve (which takes practise to find).

Main straight and east complex
The main straight is very long. The challenge comes from the corners at the end - over a crest where you need to be on the left to get the correct turn-in.
The corners go right, then left (under braking), then sharp left - and there’s a vertical drop in the middle.
The first apex is hard to see at speed, and you need to learn to look for it.

After the sharp left the track goes right then left – all easy and great for drifters!



Piano keys
The piano keys are a large zebra crossing painted across the runway - the track skirts around the side.
It’s a right hand bend then a left, but you can approach this from the east complex with either one huge curve or a curve - straight - curve. I use the first approach as it seems to fit best with FWD.

The tip going into the piano keys is to get the speed right down, the RH is tighter than you think and there are lots of spinners here. There's plenty of tarmac run-off on the left if you need it.




Paddock straight
It’s fast here, and tricky to see what's at the end of it. What follows is... a tight corner!
The whole complex becomes more difficult if you enter the first corner too fast. Learn to look for the braking point.




Paddock complex 1
The tight left at the end of the straight tightens further into a right. It’s setup as a drift corner, and it's TIGHT!
The tip is simple - slow in, slow out

Paddock complex 2
A short straight links 1 to 2, but you need a good line. Get on the right midway down it, as you've got left - right - left apexes.



Corner 1
Then... you're back where you started, but this time you're on the left hand side of the track exiting that blind complex. You can take a left apex before settling back onto that imaginary curve.

That east complex looks like a heavy trail braking area to me whats the run off area like if you get it wrong.

There's about a hunded more yards of unused threshold on the end of it

this complex eats tyres

Not as much as corner 1

Thanks for info the pic looks like a very short run off area. Got the tyre problem covered i have 4 sets of old hard slicks to use, assuming there is still a tyre fitting service at marham.

yerssss!

I suppose between the two of them we must leave tonnes of unwanted rubber for the clear up crews to play with

I always think the hairpin section eats most of mine on the Midge though

350 kgs of pig iron over the front wheels of mine ensures any corner at all hammers the tyres - marham grip levels just make it worse

Think you got the piano keys wrong - last time i was there it was piano keys on entry and exit confused
From the picture, it looks like the red 'lines' are actually shown as being on the grass? The stright red lines need to go further down the straight and then turn a tighter left hander.
I always took the 'longer' route to it which was def quicker for me, and if I remember correctly the actual piano keys curve was a much more right handed tight corner/hairpin.

Hope you all have a good weekend, unfortunatly unable to make it again frown but hoping for september/october date?

Shame about numbers likely to be attending, but at least allows 'open pitlane'.

I think the line over / around the piano keys has changed a couple of times - last event it was definitely quite tight and I think it missed the painted bit completely on both entry and exit. The paint is quite slippery when wet, and I assume it was decided to avoid actually running over it in order to give a more consistent and predictable grip level.
Tightening the corner has definitely added a new dimension - the approach is fairly quick and the combination of heavy braking during turn-in and then a sharp change of direction makes it a real challenge! I guess that's the beauty of airfield trackdays - you probably couldn't have that type of corner on a conventional circuit because everyone would be off on the grass!
My diagram isn't quite right then for the current layout - I'll change it if I get the chance.
It's a shame you won't be there - the Sunbeam is definitely one of the highlights of the event both when parked in the paddock and flying around the track.

Looking good.

I've printed out a huge photo of the airfield for you all to examine over the weekend.

I'll put it up in the briefing room.

Just to say the descriptions of the lines helped loads Rob, and hitting them right made my day even more enjoyable. Thanks for the effort in writing them up!
