Donington last night was a success!
Ferodo DS2500s - they still seem to be missing the initial bite I used to have with the Mintexs so I'll try and bleed them again, but they didn't fade at all so I could push it with longer sessions
Avon ACB10s - awesome tyres, once I got used to them they offered loads more grip and haven't worn anywhere near as badly as I expected
Also tweaked the coilover damping with some help of Chimp's friend, stiffer all round and much stiffer on the back. Car wasn't as back end happy as last time but it definitely made a good difference. Left them like that for the drive home and it felt horrific on the roads lol
Problems to address:
- Sprung a coolant leak, think from the radiator itself
- Drops oil pressure on idle, came back in after a few sessions tapping its nuts off from the top end
Going to whip the radiator off and get it tested/fixed and look into racing oil (opposed to GM 10/40 semi) and probably an oil cooler.
Ian was kind enough to lend me his bullet camera which looks like it got some good footage, sorting that out now...
I didn't get any pics but if anyone else did please post them :(

Glad the evening went well mate, as for brakes what calipers you using? My V6's seam to bite too much and lock sometimes too easy..
And for oil issues, i had some oil leaks and top end tapping, sticky tappets etc, so i got sick of it, and decided it was poor oil choice, so i placed some Mobil 1 15/50 in before i got it mapped, best move i could of done, as since then it's leaking less (lol not good to leak at all at the price it is!) due to it being thicker, and the top end tapping has gone, and no more sticky tappets after it's sat for a while, though when using thicker oil you need to let it sit and warm up for a few mins on start up, as it's very tappy for 20 seconds while it forces the oil around the engine, then it runs lovely.
It's not cheep mind this stuff, and you must let your engine completely run dry of all oil, best to take the sump off and clean it out, as it wont mix with semi synthetic, as it's full synthetic stuff, try find it in your local auto parts trade counter, as you might, or will get it cheaper, i pay £42.00 with vat for 5ltrs.

You'll have to try explain how you set the car up, as I'm guessing you need more pressure into the track under slicks etc? as i set mine on the Kumho's so the rear end squats in.. so there medium set.

Brakes, still on the 256mm ATE calipers with the old flat vented discs. They bit a bit harder before so I'll try another bleed. They aren't bad tho, but I don't feel like I'm going to lock the fronts up which is a bit unusual.
That does sound like some expensive oil! I'll try the cooler and get a calibrated temp/pressure gauge fitted too.
Set up was a bit of a guess on the tyres, 23.5psi front and 21psi rear and they seem to have worn quite evenly so wasn't far off. Damping was upped on all four corners and stiffer on the rear than front I think - I am still to check what was done as I'm not sure exactly what it's set to.
Few pics!
Kitcar chasing looking hardcore with only one headlight lol

Post-trackday tyres, looking a lot better than the T1Rs did afterwards!

Worst one bit of peel on the front left, but it's to be expected:

Had a look at the rad, it's leaking from the cambelt end but the pipework and sensor are fine so it's a duff radiator, out it comes:

The exhaust has snapped ANOTHER set of poly centre mounts, snapped clean through em!

And as my treat for the car doing so well, it's getting some nicely flocked dash parts fitted!

Only had these spare, taking the headlight switch surround over to do this week.
Flocking was done by user Prey off here and he's done a top job (has the proper equipment etc): http://www.pngclub.com/forum/member.php?20591-Prey

And some in-car vids (vibrating quite a bit so not ideal but oh well), me overtaking lots of stuff:

Clear lap where I managed around 1 min 30 secs:

Looking to be absolutely flying mate!
Take it both vids are with ABC's on? Do they need to get warm to get into there own for grip, or is it almost instant?
Cant remember is this diffed? looks to be keeping traction through the corners well.
PS: That oil is worth trying mate.
Oh one other thing, do you think pray might do some flocking for me? binnacle and center vents light pod? pm me, and if priceing..
Cheers.

Yeah I had the ACB10s on from the start. Defo needed heating up to begin with as they had gone a bit hard, but after a few sessions they were nice and soft. I just held back a bit on the first lap of each session and they seemed to be nice and grippy after that
Yeah Quaife ATB in a standard F20 box, I found myself relying on the diff to get me round the corners a lot less than I did before with these new tyres, which was nice.
-
Ah cool, forgot it was diffed, i also had issues with snapping exhaust mounts, but i have the black Polly sports on from rally design, there still in tact for now..
Should i pm pray about flocking?
-
I think it's putting too much strain on the centre rubbers and the red/orange polys I've fitted are just under too much pressure. I might cut and reweld the centre hangers, or bodge something up with a big jubilee clip through the hangers to get adjustable length
Yeah I'm sure he'd be happy to answer PMs, I really am chuffed with how those dash bits look I can't wait to get them fitted!

Annoyed i couldnt make it!!
Good stuff Iain, that looks to be flying through the corners!!! Plenty of grip there, easily outhandles my old small block. Good to see you pushing it too and not giving it an easy time like a ghey :cool:
Re-Exhaust issues, have you got another mount supporting that front box you put in?
Stiffer rear is usually the way to go on track, keep weight pressed over the front.
