Continental Tire SportsCar Challenge

Yes, the Conti Challenge is also now a SportsCar series.

2014 calendar:

Jan 24 - Daytona
Mar 14 - Sebring
May 3 - Laguna Seca
May 24 - Lime Rock (feature)
Jun 7 - Kansas
Jun 28 - Watkins Glen
Jul 12 - Mosport Park
Jul 25 - Indianapolis
Aug 9 - Road America
Aug 23 - Virginia
Sep 20 - Austin
Oct 3 - Road Atlanta

All races but Lime Rock are supporting the United SportsCar Championship. The only missing races are Long Beach and Detroit (where SCCA World Challenge are included), so there's no street races.

And somehow they will be able to run a field larger than 60 cars at Daytona. With pitstops and driver changes.

I'm really looking forward to seeing them at Sebring since the support races have been a little lacking after PWC stopped running there.

Turn Three and Turn Seven at Sebring better have extra tow vehicles on hand if 60 CTSCC cars are going to race there. I imagine more than a few things will happen.

That could be the race of the weekend--certainly the best support race of the weekend.

Thank you for starting this thread. For some reason, I couldn't find one for 2013. Does anyone know what new cars will be added for 2014?

During the Lime Rock broadcast, the Mazda official mentioned that they want to get the new Mazda3 to enter the ST series. What about Subaru BRZ? The car seems to be well matched against Mazda's MX-5. It could have been an interesting battle.

I'd prefer the Impreza STI in ST, and the BRZ in GS.

I am not sure how they're gonna race the BRZ in the GS class with its tiny naturally aspirated engine. In real life, a lot magazines tracked BRZ as well as Mazda MX-5, and Honda Civic SI. They're pretty close. BRZ loses out on the factory tires, but gets a lot better with good aftermarket tires. It would fit well in the ST class, and all the ricers would start watching Conti Tire series ;p

The GT86 races at the GTS class of the SCCA WOrld Challenge. They installed a turbocharger.

IMSA will absolutely not allow that kind of modification to the GT86. Furthermore, the Impreza STi is a hot rod, it would have to be radically detuned to compete in ST. The only solution is STi in GS, its natural class, against natural competition, and the GT86 in ST against natural competition like the MX-5.

I've always wondered how the Mazdaspeed3 is balanced to the 200 HP Civic Si that seems to dominate ST.

Hi guys, I've watched from the sideline for years, but since this is right up my alley I figured I'd post.

The STi in GS. 10 years ago the STi was a competitor to the Camaro, Mustang, M3, etc, but now really has to stretch to compete. Think about it, the STi has stayed at 300 hp while everything else has jumped into the 400-450 range, so that makes it a competitor to the V6 camaros now. Yeah we made it work, but with an aftermarket turbo and a lot of boost, and lots of engine changes.

On the BRZ/Scion in GTS and thus should be in GS. WC let them put a supercharging system that is installed at or after the dealer. The car really belongs in WC TC, and GA ST, but with only putting 150hp stock to the wheels, it needs a lot of help.

I believe Continental Tire series does not allow this sort of modification. What I heard on tv the regulation is "showroom stock". No changes to chassis, no changes to engine block, no engine head mods. Intake, exhaust, and fuel system mods as well as engine tune are allowed, as well as (I assume) brakes and suspension.

Probably extra ballast + an air restrictor on the Speed3?

The Civic SI race car should have more horsepower than 200. The intake, exhaust, plus engine tune should give it more HP IMO.

Here is a nice video about how they build Pirelli World Challenge and Grand Am Civics. The claim is that the HPD engine has 20-25% more power than the street engine:

Did you think that only IndyCar and North American endurance racing had their history rewritten? Well, the Conti Challenge joins them:

The [Rolex 24] weekend also includes the IMSA Continental Tire SportsCar Challenge, with the series returning to the same sanction as its debut in 1985 as the IMSA Firestone Firehawk Endurance Championship.

That was a cool video on prepping the civic for racing. Engine, exhaust, suspension, and brakes are the only mods besides dropping the interior and roll cage

Nonetheless, I think the video underscores the seriousness with which even an ST car is prepared. The commentators during the TV broadcast never really explain the degree of work done on these ST and GS cars. They keep mentioning "showroom stock" format, etc, making it sound as if the guys get a car from the dealer, install roll cage and some bolt-on mods from ebay in someone's backyard, and go.

However, you can see that they pretty much stripped everything from the chassis almost to the last bolt and then rebuilt it. While they can't mess with the engine or chassis much, they replaced a lot of minor parts in the process, such as various bushings (shown in the video). The took out the stock engine and replaced it with another unit from HPD. While the engine block and head may be stock, the engine was probably manually rebuilt with better parts. For example, they probably put in better head gaskets, wires, pulleys, bearings, cylinder rings, and so on. Nonetheless, the Continental cars are clearly stock, just not "showroom or dealership stock".

I found a PDF file which show the modifications that are permitted:

http://www.grand-am.com/Portals/0/Im...013%20Text.pdf

Pretty interesting stuff. The Continental Tire specifications follow past the page 140.

Good news! Between the CTSCC and TUSC spotters guides, that's probably going to be about 140 cars!
