" and there are racers there with stuff you didn't even know about."

 

 

And there, in a nutshell, is why you go to big events...  

[Cap Henry]

Commercially available rule only applies to certain parts I do believe, which doesnt include tires or guides.

If you ask Noose, Im sure he can help you source bodies. ERI doesnt show that Nean body yet, but they do show others so Im assuming its in process.

[usadar]

I would like to know about motor changes after the tech.
The following is right?

The only motor changes allowed after the tech inspection are:

1. During a move-up from one main to another.

2. In case of hand-out motors blow during the qualifying.

3. In the other cases, motor change under the green is not allowed.

[Noose]

Correct

I've got a Question about the rear spoiler. In the rules it specifies the rear spoiler can't be wider than the body.

In my photo the spoiler is wider than the molded spoiler but it's the same width as the body.

It's with the parameters of the wording of the rule.

Is it legal?

Asking for a Friend.

 

 

 

[Dominator]

The spoiler width should be no wider than the area it is being mounted to. In the example of the Lola T-70, the max width of the added spoiler is the width of the molded in spoiler on the body.

[Bill from NH]

Is that molded-in spoiler width different for each manufacturer of Lola coupe bodies or is there one standard IRRA width?

[Hot Slots]

Thanks Dom

I'm going to assume it's different by manufacturer, the body in the photo is a Kelly, the RTR is the same width as the rear fender.

[Dominator]

Bill, they all vary a little.

[Don Weaver]

IRRA doesn't set "standards" for manufacturers.

[Noose]

Well a rule is in essence a min or max standard. We establish rules to be met thus one can say one must meet the published standard.

just get rid of the spoilers, everyone runs the same bodies anyways

[Samiam]

 The spoiler’s length is limited to a maximum
of 1/2” (12.7mm) from the rear edge of the body
and must be no wider than the outer edges of
the body.

 

Body width  - 3.250 at the wheel arches.

According to Dom it can only be as wide as the rear spoiler it's mounted on. I read the Rule differently that's why I was asking. I read the rule as it can be as wide as the body, it doesn't specify as wide as the rear spoiler. But I believe Dom is on the board of the IRRA so I'll accept the answer I was provided.

[Noose]

Dom is right

Try a smaller  spoiler. You'll go faster.

I have been thinking and as some of you know that is not a good thing. 

 

Most of us retro racers run 4 classes of cars and most of the time I only get one race on a set of tires. Yes I get some practice with them, but still that gets expensive. I spend more keeping tires on my cars than any other part. Yes I could save by making my tires from donuts and rims, but that is a lot of work and mess. 

 

In IRRA retro there are three classes of cars using .812 rear tires and F1 class using .790 tires. so you can use used .812 tires on your F1.

 

What are your thoughts on allowing .790 tires on the Can-Am cars as well as the F1 cars? you don't need to change anything on the cars just adjust the rules to allow the lower clearance in the rear just like the F1 rule is now.  

[slotcarone]

That would not change anything. The standard would become the .790 rear tire and you would need that to be competitive. We run more Can Am races then alll the other classes. Stock car would make more sense to do that.

I could not go for stock car Mike. If anything I would put bigger tiers on the stock car but that would require changing the chassis so that is out.

 

I could see smaller tires on the coupe rather than Can-Am, but the Can-Am is the faster class and usually the last raced so smaller tires there seems to work best. because you can run your tires from the stock car or coupe race on the Can-Am at the end of the day.

[CDavis7]

I like this idea of 2 classes each having the same .790 tire and clearance rules. No one has to rejig their chassis and it makes the two top-tier classes have similar tire and clearance rules. We'd all be able to get more use out of our tires.

Im for it!

[Jay Guard]

Personally I like this idea, but one issue with using smaller tires and hence lower clearance on a higher downforce car, like a Can-Am, is that if you need to use softer tires (like at the recent race at Helen GA) there's a good chance of running out of tires/clearance, this almost happened to me at Helen and I was starting with .812" tires.  A lower downforce class like F1 generally wouldn't wear the tires as much.  With this in mind it might be possible to apply the smaller tires to the GT Coupes but they actually have a lot of downforce too so it might not work well there.  Stockcars might be OK but with their heavier weight it might not work there either.  All that said when using a harder wonder type tire using the smaller tires on any class would probably be OK, but that would be difficult to put into the rules.

Funny how rules changes that are designed to save money frequently wind up making the cars faster for those who aren't trying to save money.
