Hi all,

I have just booked my first track day at brands hatch for the end of november.

I have a classic wrx with 215/40/17 tyres i no i should increase the pressure for a track day but im unsure on what to increase them to.

Could anyone please advise me on what pressure i should run for the day.

Thanks in advance.
Kieron.

awesome.

What day i might join you. not done bands since last Jan. Paddock is FUN in the wet (& snow last time)

I just kept my tyres at 30 when was using road tyres. If its dry they will go off within 2 laps anway.

Firstly tyre pressures are VERY important but really depends on how the car "feedback" feels to you. As said dry and wet days are different.

Some tracks tell Novices on "Sessions" suggest to raise your Road settings by 3-4 PSi, so the car turn in is more responsive and won't fell as "swearmy" and the fact they are Novices will not generate the heat into the tyres and wheels (braking). Although I disagree with the above, it's a long time ago since I was a novice

On a trackday on road tyres, I normally let 2-3 Psi out then 2 laps come in and re-adjust Pressures back at what I prefer 2 Psi Lower than "Road setting" but may not suit you .

After first session re-check tyres and wheel nuts, you maybe suprised how much heat is generated both from the tyres and brakes to wheels. this Temperature will depending on the tyre make etc, how aggressively you drive and Brake. The pressures can raise greatly and soon the car becomes a wishy washy jelly on a plate car

My RE070's went from std 34f & 32R and 4 laps at donny to about NSF 55psi and mid 40's psi on back.

Also take your wheel center caps off, the alloys expand greatly when hot and lots of cars lose the Caps because the drop out.

IMHO IIRC

Definitely, got back to the pits at Snetterton with Nate, car cooling on tick over and the front caps just looked like they'd had enough and flopped on the floor. was most amusing

Thank you for the advice people its a great help,

I have book the am session at this novice only day
Club MSV - Car Trackdays with MotorSport Vision - Event Details

I will try 2 psi above road pressure at first and see how i get on and go from there.
Will take a pump/gauge and a small selection of tools as well.

As said above ill take off the centre caps just incase they decide to come out.

Beware of loosening wheel nuts if you clout kerbs too often......

I thought I'd "done" a driveshaft, but it was just the NSF wheel falling off !

Always handy some Elecricians PVC tape and drinking water

I always keep a set of front and back old brake pads in toolbox, as much better than creaming them and having none.
