Hello folks, I'm a relatively new owner of a 2007 350Z , purchasing it in Aug 2012, but as its my 2nd car I don't get to drive it too often. So I've decided to do at least one track day a month for the next year, to enjoy the car and develop my skills as a driver, as I'd like to enter some form of cheap club racing events, in something like a 240sx or BMW E30 (dream on?!). But I am in no way ready for that at the moment, hence my plan to improve my skills.

The second motivating factor is I watch a fair bit of YouTube car shows (eg Drive), which are very entertaining, but they are somewhat irrelevant to me and I believe the avg driver. They are either hooning around in hypercars on airfields (ala Jeremy Clarkson) and/or expert drivers like Chris Harris power sliding cars on winding roads. What % of 911 drivers have done that on the road? (ok done that and not crashed?!!), never mind taken their car to the track??

I hope to have a video or 2 every month, where I'll briefly outline my objectives and then cut to a video of the track day, hopefully speak to some fellow track day enthusiasts and check out there machinery (nothing wrong with a little automotve eye candy). But rather than just the usual single camera track day video looking forwards, I'll have multiple cameras set up (forward, rearwards, driver facing so I can talk to 1 camera, pedal box and instrument binnacle, not outdoor body panel cameras to begin with. I'll occasionally change to my BMW E46 330Ci (to mix it up, & so i dont become too accustomed to one type of chassis set up), and once over the next 6 months hop into a Porsche Cayman at the Porsches driver centre, for 1-1 instruction at Silverstone race circuit (already done this once in a 911 last year).

The first trackday will be at Bedford Autodrome on the 15th July, video will follow shortly after.

So my first query is:

I currently have Bridgestone RE050, with a staggered set up, 225/45 R18 at the frontand 245/45 at the back on Rays Alloys. Rear tread is at about 3mm, fronts at about 4-4.5mm

Finally getting to my Q!! I feel its important, as a beginner that I learn to recognise that I am approaching the limit, rather than outright cornering speed. My rear tyres will need replacing after the track day on the 15th, but what should I replace them with? I think the Bridgestones RE050's at 245 width will mean the rear may be just too sticky, and the overall grip limits just too high.

Also I'm not a total noob to track days. I've driven the following on experience days at the track: Aston Martin DB9, Subaru Impreza Wrx sti, Mercedes C63, Mercedes SL65, Porsche 911, and a couple of proper track days in my own 330ci over the last 4 years. Of these cars i was able to "unstick" the AMG Mercs out of slow corners, but the 911 was planted on throttle, but I could feel the grip limits on corner entry, and really feel what the front tyres were doing.

Any advice and comments would be greatly appreciated.
