What temps did you see later, as I didn't see anything out of the ordinary for track use?

Around 100°C for water and 115°C for oil is not out of the way for good quality oils. I would say anything under 110°C (230°F) water / 125°C (257°F) for oil is acceptable (providing good quality oil is used and changed regularly).

The Honda S2000 runs a 1.1 bar radiator cap = 125-127°C boiling point with a 50/50 mix.

If you change to an uprated 1.3 bar item, this increases 130-132°C, before the coolant boils, so up to 110°C gives a good safety margin.

Regarding the brakes, I would always do a full lap of the circuit to try and get some cool air through everything (trying not to use the brakes, but at a good speed but high gear where possible).

@ Fellblade in the wet i was using Goodyear GS-D+ (old which i have kept for wet days) and in the dry Toyo R888R but also used Toyo R888 Pirelli Troefo R, Avon ZZR

im not sying they are the worst tyres but i have used T1R on my S thought they were quite good untill i went to a more focused track tyre, people was telling me how much better the track focused tyre was i was like 'yeah ok' until i tried the tyre with no other changes in the car so much better on track and you can push more, it gave me a lot more confidence in the car.

Highest water temp I saw was 105, oil 115 and both still rising after 10-15mins session. Air temps were 18ish, plus sun was out, so not that warm. I had a full lap off the brakes and a slow run down the runway and back before parking up. The discs were about half worn, but probably 30k+ miles and a couple of hands full of track days.

Also, oil temp is measured at the sump plug, so I kept a bit in hand for that as its probably warmer up near the engine. Running a 1.3bar rad cap too.

Hi all,

Here is my short video from Brands Hatch - what a brilliant track!

Yeah, from all trackday videos mine's doesn't look as planted as some other s2000s.
My choppy driving and tyre choice doesn't help I think
I prefer oversteer to understeer and you can see it from my setup.

Front setup:
camber -2º 20' on both sides, -0º 22' (toe out) and 5º 30' caster
Rear setup:
camber -2º 0' on both sides, 0º 44' (toe in)

BC coilovers on hardest settings, other than that - OEM 99 JDM suspension.

Tyres/wheels combo
17 inch 8j and 9j wheels
Toyo r888r 225/45 at the front
Nankang ns2r 225/45 tw100 at the back

Massively choppy with your steering and I am sure the different tyre choice front to rear won't help.
Soften up the rear a couple of clicks will help.
Your front will be much gripper with the r888r and the -2 camber and the toe out.

Just found this on my searching for track overlay for my GoPro3! What did you use for track overlaying BTW?
MB - raced an s2000 a couple of years back.

MB had a later year car which requires less toe than the earlier ones. Ading more rear toe in will make it less slidey, but more sudden when it does decide to let go.

The biggest cause is the square setup on tyres. Have a look at the "Racing" forum https://www.s2ki.com/forums/s2000-ra...ompetition-11/ or search for square setup fro lots of useful info on how to set the car up.
