My understanding is Michelin is going to have 2 compounds available (dictated by them/IMSA, not the teams.. they don't get a choice) based on the estimated ambient temps. They have a "hot weather" tire and a "cooler weather" tire.

Talking with some of the GTD drivers the Michelins have a much quicker/steeper drop-off in terms of grip/time but that's to be expected from a normal racing slick. It should have an interesting effect on the strategy/race pace of the GTD and Prototypes. The Continental was very hard/conservative which made for less of a drop off.

Great feedback on the tyre differences Mike! Thank you!

The GTD Entry list is ever growing! Precision Performance Motorsports (PPM) announces a full season effort for 2019.

The Lamborghini seems to be a popular choice.

From what I hear, Lamborghini gives a LOT of factory support to teams that run it's GT3 cars - more than any other manufacturer, according to some sources.

It's one the pricier GT3 cars as well, so I guess it's good that you get something more for the money.

I guess this belongs here. Sean Rayhall to retire:

Strange to me but sounds like he'd like to try something else. More power to him.

It was on Endurance-Info too (yesterday)
http://www.endurance-info.com/fr/sea...a-sa-carriere/

It seems like the lifestyle and all the stress involved were getting to him, and he decided that was not the way forward for him?

Coach Ep · 18 Dec 2018, 14:08 (Ref:3871127)

Saw the guy at Rd. Atlanta a few years back sweeping up the Imsa Lites races before the Petit, blindingly fast, plenty of bravery too.

I'll miss him, always thought he had plenty of speed but he never got to show it in one of the front running prototypes - hope he'll to grips with whatever is bothering him, perhaps one day he'll be back.

broadrun96 · 18 Dec 2018, 14:51 (Ref:3871136)

I'd hope he comes back around for HSR events, he spanked the field on a rainy Sunday in a 914/6 in the morning enduro a few years back at The Mitty. Even the modern GTs with a few pro drivers had nothing for him and was an insane drive. No idea who he was at the time and only hearing the name Rayhall my first thought was Graham's brother is faster than he is. Maybe he will have the time with his new career to be the occasional hired gun to play in a rich guy's toy on track but it does seem like he's a more laid-back guy and the stress of never landing that factory ride and every off season bringing that search for sponsors just wasn't his thing.

Hopefully he still enjoys the racing and it's just the off track business, but very necessary, of raising money that got to him. Too good and consistent to see him go but not sure I could handle the stress of that life myself no matter how much joy the on-track action would bring.

He caught my eye in the Lites races too. I wish him luck in his future endeavors, but sounds like he is done with racing.

HART racing are teasing their 2019 plans....HOPEFULLY its a reboot of their IMSA program, or at the very least an IMSA program in another category.

Coach Ep · 19 Dec 2018, 14:41 (Ref:3871421)

From a while ago:

***Several European Le Mans Series teams are close to confirming LMP2 entries for January’s Rolex 24 at Daytona. It includes Inter Europol Competition, which recently purchased a Ligier JS P217 Gibson, as well as Panis-Barthez Competition. The new-for-2019 class, which will be spun off from DPi machinery, is set to feature Pro-Am driver enforcement.

from https://sportscar365.com/imsa/iwsc/r...ay-notebook-5/

I also vaguely remember Graff expressing an interest.

Edit: bingo! http://www.dailysportscar.com/2018/0...-24-hours.html

We'll see.

PR1 signs Audry and McMurry for their Oreca P2 for the 2019 season:

https://sportscar365.com/imsa/iwsc/p...or-oreca-lmp2/

Those are some quick kids, and the hands on favorite to win the LMP2 title. Mostly because nobody else has confirmed a program......

MaskedRacer · 19 Dec 2018, 16:43 (Ref:3871457)

Just thinking that it could not be out of the question that the IMSA guys will be paying close attention to how DPI speeds compare to LMP1 non Hybrid (Rebellion, SMP, ByKolles) at Sebring.

If it is close enough they could open up these cars to race against DPI's from 2020 onwards. BoP adjustments I'm sure are needed but maybe not be extensive. I feel that it will be close myself.

Nick Woodbury · 19 Dec 2018, 17:29 (Ref:3871463)

WRT Confirmed for the Rolex 24 in GTD in partnership with Speedstar racing and Audi Canada. Fantastic!!!

I think the lmp1 cars will still be 4-5 seconds a lap faster in qualifying trim. But you do bring up an interesting point about the series comparing speeds.

canaglia · 19 Dec 2018, 20:36 (Ref:3871496)

this year DPi didn't receive any boost as far I know, still remain in about 930kg x 580-600hp performance window; I expect time improvements mostly because of michelin.
WEC lmp2 have basically same aero, just lack some torque. Dunlop lmp2 tires shown to be as good (if not better) as lmp2 michelin in past.
To make an example if 2018 silverstone lmp2 pole is 1.44.9; I'd expect a comparable "ideal" DPi pole in about high 1.43 - low 1.44.
Still far from rebellion-SMP 1.39.

TF110 · 20 Dec 2018, 01:33 (Ref:3871533)

They slow down the cars purposely at Daytona also, because they seemingly have a 'do not pass 200mph' order. Lmp2 were doing near 330-340kmh at Le Mans. I think it's pretty certain they could go faster but probably stack on the wing at Daytona so as to limit the top speed. I don't know if that would equal faster lap times though.

jimclark · 20 Dec 2018, 03:38 (Ref:3871558)

'A shame about the wingage (new word?) as I miss the days pre bus stop. Mid '70s 'Greenwood Vette (rumoured at 240; reliable source at the time stated 220+) followed thereafter by 935s honking right along.
I imagine times would drop as there's only the 5 real turns (T1, Int'l Horseshoe, W. Horseshoe, infield exit and bus stop) vs. 3 long ('haven't been since GA days, are they lifting for the kink?) and 2 short straights .

NaBUru38 · 20 Dec 2018, 15:07 (Ref:3871652)

IMSA claims they are close to reaching full capacity for full-season entries.

His amazing story continues. Good for BMW and his codrivers for tacking this on.

That is up to you. There are typically fewer posts around the holidays, but the Roar is just around the corner.

You know, you could start that discussion by sharing your thoughts and observations.

I am waiting for entry lists and such ... but having been through so many Roars, I am personally not going to have much to say until I see some performance numbers---when we can all start speculating about how much each team is sandbagging.

Seems like some interesting teams might be showing up ... but i haven't done much investigating yet.

What do You think?
