@johnoggy yea mate, car ran very smooth all day. the map is a safe 1.2bar as its all standard apart from FPR,Exhaust and FMIC.
I am currently reviewing brakes and think the AP 6poy setup with RC6 pads is the way to go so ill be ordering them next week for the next track day then post a video to see the difference.
Also i need to source a new fuel tank preferably that has a baffle setup in it and using original sender.

Investigate if it would be easier to fit a fuel swirl pot instead, with the OEM pump acting as a lift pump, and the swirl pot feeding a separate pump. Might be cheaper and easier
swirl pot and large Bosch 044 fitted and works like a charm, i run almost empty at a shakedown test on Monday and it was perfect.
The knocklink did flash and detects the det and fuel starvation but my Zeitronix ZT2 detects a drop in AFR just before the event which is good and the logs from it help massivly.
the car has also since been corner and cross weighted and geo setup, still understeers like **** but the below should help including the castor adjustment.
Geo is still really bad so i have alot of whiteline stuff ordered-
some vids of shakedown on Monday
@DDS789 i have it corner weighted and all. setup for -1.5 front camber and -0.7 rear camber and 2mm toe in at rear. Running Tein coilovers (unsure of spring rate) with front 4 clicks from hardest and rear full hard. The above items from whiteline come tomorrow so i will fit for Monday and run a shakedown before i race again next Saturday. I have absolutely no feel after initial turn in(weight is on the front) once i go neutral and/or power it is ICE at the front. So antilift/castor + bump steer correction kit will help put the wheels into positive castor a bit as well as the really beneficial ARB on the rear.
I will be putting both ARBs on not just the rear so i will have to play with how hard to run them. Im thinking of running both the 22mm front and 24mm rear on the middle setting, any advice here?
Lets hope i finally get the frontend grip needed on the R888's and if its really dry get slicks on.

What's your front toe? Your rear toe is good Im running similar but with -1.5 rear camber and -2.5 front, I'm running decent toe out front and the car is brilliant no understeer!
The anti lift will help A LOT imo
Just fitted bump steer correction to mine this week doing all the diff bushes and engine mounts as well, also gone adjustable arms at the rear as the bushes were gone in the original arms
If I was on a track day with you I'd tell you to experiment with softening the front dampers and less tyre pressure front
Would soften turn in but may gain grip mid and exit of the corner corner
i think the arbs will help, do you have them fitted?
I just cant wait to sort mid and exit turn, i loose all my time in hairpins and tight corners, my other vids on my youtube channel will show that also on a trackday in Kirkistown.
I have my front camber that agressive before Geo was done 2weeks ago, that camber didnt make a difference for me so for tyre wear and coverage we adjusted to less.
after i fit all the above i will need to then look at rear camber bolts potentially depending on how it acts.

Hmmm
I must admit I've tried a few different camber settings and not a massive difference
Wouldn't worry about tyre wear too much scoobs (at least for me) seem to be very gentle on the tyres
It's toe that's done the most for mine. I've run parallel and moderately aggressive toe out on the front the difference was crazy
Ive run toe in and a toe out rear set up as well
Toe out rear was over steer madness on turn in, mid and exit
But was very hard to control
Best set up by far for mine has been toe in rear toe out front
Yes I have the same arbs front and rear mid setting rear soft at the front, have all the other bits you've bought as well ha
Got BC HM coilovers as well , definitely haven't taken advantage of the compression and rebound settings yet! That's something I want to learn about

@DDS789 thank you mate, i hope to get a shakedown done before the big day next saturday, i just hope it stays dry so i can feel the grip. my word it would be nice to have frontal grip, i pass things after chicanes or on straights as ive good exit speed etc but to find them right behind me as i understeer my way to the grass lol..
maybe harrys laptimer will no longer show me red in these areas.
I just posted up asking the arb setting questions but i see you have it answered above, perfect pal.. ill also look at sorting my toe out at front and keep the 2mm toe in at rear before the trackday.
Fantastic build there. What do you have in terms of oil control? Baffled sump?
yes big kit under the 18;s and just about fit. i run with very good and probably the best CL RC6 pads.. amazing and best money ive spent yet and im still standard engine etc.
oil control is the mocal massive radiator and thermo plate feed with anodised lines all heat wrapped.
next is the baffled sump /plate which ill order from somewhere??? and put in during xmas.
Also in my new fuel tank i put some baffle form in the opposite belly to the primary walbro fuel pump.
I can literally run near empty now and my walbro supplys the swirl pot and bosch still have plenty of suppy to the rails.

Get a baffled sump in before running slicks. Long bends pull the oil away from the pick up in std sumps. Get in touch with Alyn at AS Performance, he will be able to sort you one.
lost my previous post there. thanks i ran slicks before @LewisScoob and i know i was worried with the G i was pulling in the hairpin. ill contact alyn, is there a contact here for him? also i assume its the baffled plate setup will be ok?

Alyn will tell you better but you'd be better with a twin scroll sump and then baffled which would require a dipstick and reinforced suction/lift pipe.
Plates/trays prevent oil going to the heads, which is an issue but less so compared to keeping a good depth of oil around the pickup pipe as baffled sumps do.
Given what you've spent on the other mods, unless you're planning a rebuild soon you'd be better spending money on the sump
@LewisScoob no im all for that, i mean the baffled plate will be ok with the baffled sump or do the go hand in hand. anyway ill call him and get ordered.

when I asked RCM about running both they recommended one or the other. The reason they gave was running them together could restrict flow back to the pickup area.
I went for the baffled sump on that basis. Plus it has a port for returning catchcan oil.
@GT_MAXER
Will have to check but was a similar number to the rear
Maybe 1.5 toe out
Did you say what you're running on the front?
Also my mate does the videos there's 3 of us that do the track days in 3 cars can see some footage here, only really started doing the videos like this this year, get into the videos a bit for fast footage

Been running mine with no issues with an oil scraper and baffle plate with standard pick up
But it also depends on the tracks your visiting and how fast you are as well
From what I know there's a couple of southern England tracks with specific corners that are engine killers
I mainly visit blyton, cadwell, croft, donnington, Anglesey, and nurburgring and have had no issues
Doesn't mean I'm not looking into oil control though ha haa
If I was to do the least extra I'd go twinscroll sump and the WRC pickup pickup
Bare in mind my engine is forged and 10 years old now so it doesn't owe me much! I think next build will a 2.5 engine for the extra torque and spool
My front is neautral no toe yet. but i might go a small toe out before next week, 1degree would be approx 4mm i think so a bit less than that.
early next year i have to upgrade the turbo to something still focused on no lag and good power delivery so maybe 18g billet suit my rev range and requirements or even 16g. who does these as whole units ready to ship?

Nice to see the videos too, keep them coming.
