Ralf, good work on booking early as I see it's now sold out. Matt has an AIM Solo and will bring it to record all of your times, but it might pay to remind him as the times are so bunched that any other time keeping method won't cut the mustard. Maybe talk to Chris about plans for the card and remote. Next week it will be Walter and Tony who will need access.

Thanks, will find out who he used.

Thanks Ralf. I will see you out there on Saturday. I really appreciate your effort in getting new brakes for BB. I will certainly use them but it appears as if Chris hardly touches them. After my last rushed and frantic effort to decrease my time I will be trying for smooth and calm this time.

John McM

Three fastest runs to date.

Plenty of time on the day to get that low time. They should be perfect conditions. Maybe Chris will share the secret?

I think no brakes so he just drove, powered through the corners ?

John McM

Not sure Doug. He said the brakes were starting to fade during his session. I think he nailed the time in 3rd lap and then buttoned off. We thought he knew he'd beaten Pete's time and was cruising. We now know he wasn't able to push it with the brakes he had left. Certainly turn one is taken differently to the more powerful rear wheel drive cars. Next time he's out I'll shadow him in Herman

I was studying some traces from the GT3 last night. I did one lap out of 9 on Turn 10 sweeper as a tightening radius the rest were double apex. The tightening radius is definitely quicker and this is the overlay between two laps (7 and 8 - end of 8 lights were flashing for 9 which was warm down).

I think its a good graphical representation of what is happening when you double apex vs constant radius turn 10...

A star studded line up there. She's already booked in for the 23rd too (Tony, the ticket says the gates open at 8am) so here's hoping nothing happens to her that won't polish or push out...

interesting Macca - needs a big sample size to see what is faster on average but maybe at pace the double apex has a couple of advantages.
1) As Troy said on SITT 'the endurance line' is kinder/less wearing on the car and tyres
2) for non pro's the double apex may be easier to be consistently near the target pace as I think the margin of error on the grip side at the key entry part of the corner is more because the tyre is stressed mainly in forward rotation only not side.

The last corner at Manfield is similar as you can use both lines. I always use double apex

Macca

Swings and round about I think Graeme. Double apex you keep the speed higher going into the corner but scrub off more mid corner where as tightening radius you brake earlier but hold more speed through the corner. I think you are right though it depends on the cars chassis, tyres and limit of adhesion. I actually think double apex is harder to get right than constant radius as you need to time your braking and turn in precisely whereas constant radius you just sit on a trailing throttle slowly squeezing it and can feel better where the traction is (outside wheels under load).

John McM

I am positive that BB will see a few more sessions yet, however eventually we need to expect some issues. No-one is taking it easy and the track can bite even at these speeds - witness various gardening episodes and a close call on Turn 1. There's also the possibility of breakages. Within reason I think we drop it back to Jono in need and ask him to fix it. We can poll co-owners if it's a biggie.

Maxem

Last one in her at time of catastrophe gets the job of putting her up on blocks on your front lawn and running $1 parts auctions till she's all gone.

John McM

The seat, harness bar, harness and extinguisher will hopefully live on no matter what. I'm hoping we get bored with her rather than end up with a $1 auction. I still haven't come across a similar car for myself. At least not one for less than $2,000. We bought well considering our common car buying weaknesses.

John McM

BB co-owners - I've just received the notice that BB's rego expires 7/9. I think WOF is November. We can probably sneak in the NITT without renewing, but I think there's merit in renewing 3 monthly for $77.50 as it gives us options e.g. If someone needs a car because of some issue at the track with their own it gives them the option of taking BB.

Thoughts?
