Trackday mods?

[OleVix]

Having completed my first trackday in the chim, I cant help but wanting more of the good stuff that improves handling. I want your opinions on what works and whats horseradish. Was chuffed by how the chim handled itself against more modern and more expensive equipment... wasn't surprised to see the mx5s in the rear view mirror though

What Ive done so far:

AST adjustable suspension from racing green. Major difference in handling and predictability. No surprises anymore. Car is a bit lower. Camber is -1.5 all around.
Leven droplinks front and rear. Didnt notice much
Lightened flywheel. Now its 10kg, it was 12.5. Felt a nice difference, want to lighten more! Heard of a billet 5kg one!?
Decats, usual smooth bore, big K&N filter, shorter trumpets
Toyo 888 tires, huge difference!
CG lock seatbelt lock, helps some

Future:

Stage 3 4.6 hicomp engine. All parts ready, putting together this winter.
Brakes?!
4 point harness?
Roll hoop?
Lower rigid seats?
Bushes?
Removing stereo, which never is in use anyway
Moving battery? Was thinking two mc batteries linked to save space

That's pretty much the recipes of my old 4.6!

Front camber was about 2 degrees, no toe in.

I'm gonna experiment with thicker ARBs now but you've just about got it.

What springs are you running, should be at least 400/450.

Don't know about the springs, does it say on them? Just bought the package from racing green, they installed and set it up. I was thinking that the ARBs are connected a bit far inwards on the Y-arms, have someone experimented with a wider ARB and moving the mounts?

Thanks guys, will check out the brakes next... I have 16" front, but the main pronblem with the Image wheels is that there is actually less clearance in depth now, from the back of the centre to the beginning of the caliper. Maybe I can find calipers that dont extrude too much, 2 pot in the back or 4 small pots? I have the tools to make adaptors myself

Rears - no need to upgrade, they are already 273mm IIRC. Just change the pads for something like Ferodo DS2500.
Fronts - the Sierra Cosworth 288/289 kit seems favourite for 16 inch wheels, but you would be advised to find someone running them and try your wheels on their car before you waste £££££ (or Norwegian Krone) on something that will catch.
Is the car in Norway or England?

The car is in Norway. My neighbor has a mk1 Escort in progress, can borrow his calipers to test cossie engine, brakes, group A fenders etc

The most important mod if you are using R888s is a baffled sump. On fast left hand corners if you at the limit of grip without one you will get oil surge and destroy the engine. I speak from experience having destroyed engines this way in 2 of my TVR's. John Eales do a good one. It just bolts on about £400. A lot cheaper than a rebuild!

Can the existing sump be modded with baffles that work? Have fabrication and welding at hand

I do have some experience from before, did a season of 6hr races with a group of mecanics... 10yrs ago had the licence... i know a bit about flow and consistency and choosing correct lines. But I am rusty and need to get a grip on my heeln toe... I have big feet!
