I looks like for 2007 the rules are WIDE OPEN to ANY FWD 4 cyl car!!

IMHO, This will be a can of worms compared to Spartans rules,,,, to many Rare. expensive cars are legal,,,NOTE last year they only allowed SOHC cars, so the NEON was the car to build,,

You guys are very smart, so,,,In your opinion,,,What would be the HOT cars to build???

DOHC Cobalt?

Dohc Focus?

Eclips?

Neon?

Hyundia Triburon?

What do think of these rules compared to your rules??

well the IMCA engine rule is pretty open but the claim rule and imca claims frequently keeps things in check a little but those rules are pretty wide open. in my mind the cobalt will be the car to build because the ecotech motor is really strong and you can do alot. but yea that's gonna be an interesting year for the imca sport compact class

However, who in their right mind would buy a Cobalt, turn it into a race car, and compete in a $1500 claiming class?

Instead, you'll see junk old Hondas being used.

and Quad 4 oldsmobiles, they were about 185 HP in Calis, with just a little de-smogging = over 200 HP.

also the killer Eclips will be used too.

Trick, Rules like this are what is costing racers to try to out spend each other. It unfortunate that with all the wisdom of IMCA that they would allow such a haphazard set of rules to be put in place. I for one have been working very hard to keep a cap on the pony rules at Spartan. This is and should remain a class in which exotic cars and expensive tires are not allowed. Lucky for us Mr. Leisure was receptive to the drivers and others at the rule meeting and didn’t put in place the misguided tire rule. Otherwise we might be in the same boat. Mg

As the owner of a Cobalt that I drive to Brighton daily, and for 'round the town use, (13 months old, 49k miles already) I wonder if it may be the new pony stock hot car in the future when they start to get used up or whatever. I know this much, it has good power and seems to handle well when I get froggy, but I don't know the particulars of running a FWD on a track like Spartan.

What do you all who know ponies well think, is that going to be a top notch 4 cyl car, or would it not fit/not run well within the current rules?

Just curious, maybe someday my wife or daughter may wish to give this sport a try from the drivers side as opposed to the crewing side.

have a good day,

schinde

Im with you on that one Torg38. This class was started so people could race with out spending alot of money, and over the last few years it has gotten way to outta control. You can only imagine what kind of drama this is going to bring to this class, trust me this class does not need any help creating drama. this will definitly bring un needed tension. Maurice do you agree with the rule changes? And Why? Just wondering. Do those rules applie to the fig.8 cars?

Bo, those rules posted above are not for our tracks (Spartan & Springport).

Those are rules posted for IMCA Sport Compact racing at other tracks that use the IMCA and I believe Trick was only posting to gauge what people thought about those rules.

It doesn't matter to us. These rules do not apply to Spartan or Springport.

Notice how Arnold stated in the first message "This will be a can of worms compared to Spartans rules".

He's referring to the IMCA rules which are used by IMCA sanctioned tracks for their 4 cylinder class. It's just a friendly discussion to get our opinions on the subject, not to change our rules in any way.

Heres just some obsevations of what has happened up here with the opening up of the rules in the Pony Stock/Mini Stock class at some of the tracks.

A couple years ago a few tracks allowed 16v sohc cars to run , this brought in the Neons and the Hondas (non vtec) . At about the same time they opened up the tire rule any tire 7"wide max H rating . Overnite this made the exsisting cars just about obsolete .

The tracks that went this route have had car counts dwindle in just two years and now have pony stocks that are very $$$ . In what I see as a foolish move two of these tracks have now decided to let dohc cars run to see if they can get their car counts back up . I know of atlest one guy that is now building an Acura that is very exotic with adjustable struts etc etc.

On the other side of the coin are the tracks like I run that kept the rules more like you run down there at Spartan but no Neons (12 V sohc max) . These tracks also have a points champion must move up a class rule and a weight added to any car deemed to fast rule . The results are at my track they have around 50 cars a nite and have had to go to an A and B feature format .

Thats just how things have worked out here in the great white north , your opinion and mileage may vary .

At this point in time, since nobody has seen this car or know who the driver is, it would be best for him to just show up at the first Sunday open race. He won't have to pay the $50 registration fee for the Sunday shows. If he were to run a Friday show, he would have to be a registered driver and if we don't like his car, then what?

By the way, who is the driver and what is the car? And where has this car raced before?
