Just thinking of doing my first track day, will be quite a while away yet, want to make sure my rebuilds well run in first, what's the name of this free iPhone app then?

We were at Castle Combe on Tuesday and the sound chap there said some meters work the sound on air pressure as well. He seemed a bit of a boffin but I also recall seeing him in this months Redline magazine. He said that some cars although seem quieter are not due to the pressure. All very complicated

Hi i see you're from apex trackdays, as a noon and first timer what do I need to do to do my first trackday (in my own car), I take it I need a helmet etc not looking to do anything major just have a little blitz round the track in my car, how does it all work? Thanks

Mike @ ApexTrackdays

For one of our days. ( Mallory next week would be a cheap first day for you at £130) generally need the following
1. Helmet. Hire for say £20 or buy
2.Long trousers and long sleeve shirt. Alot of circuits insist
3.Driving license. Many circuits insist
4.Prepare your car well. Empty the crap out of it. Get it serviced, tyres etc, change brake fluid to dot5 or motul 600 or similar. Will pads be adequate? They will take a pasting. I think a hand held fire extinguisher is important.
5.Take it easy to start with.
6.Try to get tuition on track. Free with us!!

Enjoy it!

I downloaded one, but maxed out 100db, so my mate downloaded another on his iphone, which ran to 130db They wont be precise, but it will give you an indication
