Awesome John, thanks for this post! I love to read about what is done to stock production based cars turned into race cars.

What is the rules on wheel are tire size? Did you change out the brake caliper and rotors to something else?

Would the rules allow for a PDK car?

 

BGB, good luck this season with the Cayman S. Hope you close some ground on the competition with the extra hp from the mods. Wished they had allowed for a bigger Wing than just the factory aerokit. That would have made a BIG difference.

Are you going to be testing at Homestead?

 

Awesome John, cant wait to see it January.

 

Mr. Gomez,

We will indeed be at Homestead for testing. We've never met but we should if we ever can. I hope things with your Cayman are still going well.

 

Mike,

We're only allowed to update the front 318mm rotors and rear 296mm rotors by 5%. So they're Girodisc front/rear rotors with race pads, but with stock calipers.

Thanks again.

John

 

What cars are you testing and running this year? What drivers are coming back?


I sent you an email through FB.

Thanks for the report. There is a lot of interest in the Cayman as a race platform and Conti Challlenge is a great format. Conti is one of the only race series I religously record and follow after F1. I hope to see it running at Homestead.

 

Mr. Disasterman,

I wish that more people thought like you! I pray that slowly but surely people will lean towards the PCNA variants, specifically the Cayman, even though the 997 Cup is a true race car. No one wants to pay $50K for engine/trans rebuilds and we've been getting interest from people that have Cayman track cars, to have some true Cayman offerings. Fingers crossed. Thanks again.

 

Anthony,

We're just going down to de-bug the new car and try and get it close to the black car. For that event, it's just Cosmo, Stew Tetreault and myself. I figure I'll let Cosmo do the whole rear wing vs. no rear wing test in NASCAR 3 and 4 and he can tell me if we need it or not!

 

You are such a nice guy to let Cosmo test that.

Cant wait to see this thing run!

 

John, who will be the drivers for the car in the upcoming season? Will seats be available for rental?

 

Frederick,

That has yet to be decided. We've always in the past tried to get people for the full year. I'm working hard to find someone with funding to take the car for the whole season...no luck yet. If we had a 3rd Cayman built for one-off races, i could certainly do something like that. I told Mike P. to send Carlos' street car down and we won't tell him...and just convert it!

 

thanks. How about the 911? Will it be available? Funding for a full year is not that easy for mere mortals

 

John i asked Elmo to try and get me some funding!!
