$225 is a damn good price for a functional part.

Mounting? - "We used a bolt at the upper rear of the air dam on each side, the front 'hooks' over the grille opening."

Brake Cooling? - "We have included the cooling duct opening but no attachment."

Is there an underbody portion? - "Yes it is completely closed on the bottom."

Got this from Mike @ ISC Racing

looks pretty tight

I'd like to see one painted.... because right now I vote that it's horribly ugly but most likely functional

im gonna say not functional depending on what its mounted to.

judging by the stuff they sell id bet its very much functional

As long as it prevents more air from going under the car, then it's functional. I'd probably mount it sturdier if it were mine.

Anything that ugly needs to be functional unless it also fits Civics.

lmao ^

I bet it would look a ton better painted.

I agree on the paint.

lol.. paint just adds weight.

If i didn't have a RB nose, i'd get it.

holy snow plow

It'll look even fuglier after a couple speed bumps.

That thing pulled a full 1.5 second off a 2:30 lap time. It was designed around the "limits" of the SCCA ITA rules, so it's looks are come from function and rules first. The one I ran was made from the notorious BSR sheet plastic and an aluminum carpet threshold. Stuck to the front using industrial velcro. Never deformed, never came off and held at 120mph over and over.

i like that one, but it further implies the mouth look, but he looks happy

they have some great parts, glad you put up the link.

it kind of resembles a spec 7 front, I like it, but needs better mounting and paint.

i hope you dont have dips or bumps or steep drive ways or youll be saying bye bye

It was never meant to go up a driveway, because it's meant for a race car.

:werd: that doesn't seem to be getting thru
I may get to try this thing out in November. :D

+1 to kotomile. It's way to low for the street. Fugly is just dandy at the track for a functional part.

I consider mine a race car that is driven on the street. I am running the SM linear spring rates (700FR/325RR). :cool:

Race car = race car, street car = street car. A street car that sees track time is a track car.

What about?
 

So what is a Porsche 996 Cup Car that is full race spec but driven as a daily driver? Race car, track car, or street car? Oh, it is used for some AutoX, but no track time.

symantics ftl.

ISC does indeed have some nice items. I am running their oil cooler. Don't forget it appears to be low because it's on a lowered race car. Might make a nice addition to someone's car that doesn't already have a splitter. I'm going to keep my GV front splitter for now. I already made a DIY undertray for it.

I thought I was the only one running those rates. :rly:

EDIT: besides actual SM cars, that is.

I am thinking about upping it to 350-400RR, kind of soft at 325.

pics of said undertray? I have a GV coming and would like to do something like that.

Try to take some today. To explain it, it's about .080 ABS plastic, in the shape of a mushroom. The front edge of the abs fits inside the GV lip right at its base, screwed into the lip with a few short screws, then extends back to where the OEM pan bolts to the crossmember. The sides extend as far toward the tires as possible without rubbing. There is a noticeable improvement in front stability with it in place. I did a little test on the same highway with and without it. I will eventually duct air from each of the splitter holes to the rotors, for now they're just open. It's very easy to make, esp since the GV lip is there to support the front of the abs.

Heh, am I crazy to be considering running 900/450?

perhaps. The 700s are plenty stiff.

630FR/315RR 'corrected rates' don't seem too bad. I was considering 500-600FR/325-400RR (725-850FR/475-575RR spring rates), but am gonna start low and then work up till I find a setup I like. The right setup has alot to do with the size and setting of the swaybars, too.

Well, SCC did a good write up on the actual motion ratios on the suspension for the Miata. It's like 1:0.7, so running 700lbs is like running 490lbs on a Mac Strut car.

Everyone who has driven my car is amazed that it isn't that rough, plus anyone who runs SM will tell you they are undersprung for a racecar. If you talk to "pure racers" they use the sprung weight of the car as the initial spring settings, and then increase them as needed to get the handling characteristics they want.

Same here. I meant the 700s plenty stiff for the street.

Here are some pics of it painted from the website:

Not too bad painted. For a street car, I kinda like the Garage Vary better. Just an opinion though.

The one thing to keep in mind about the design is it MUST fit within the SCCA IT rules for spoiler specs. I qualified the 92 ITA Miata on the pole for the ARRC enduro with this spoiler AND it is a phenomenal piece. It may have slowed the straight line speed but more than made up for it with corner speed. The added traction to the front end on entry to high speed turns was absolutely astonishing. The car did exactly what it was told. Unfortunately the owner got run off in turn 1 during the race and the spoiler dug into the clay and basically ripped the entire bottom half of the nose off the car. That incident demoted us to a second place finish.

Bump because this seems relevant to my interests.

Has anyone besides m2cupcar installed this and liked it? I'm thinking about buying one.

On your ITA car, were you running any spoiler to keep the rear planted? This sounds like an awesome mod but I'm afraid of making the car oversteery at high speeds.

+1 Looks great painted definitely looks better than the stock one!

Car + logbook = racecar

No rear spoiler - rules didn't permit it. Of course we're talking about 114rwhp too. I have run a wing on another Miata (NB) and it will do what you want- plant the rear. Sav posted up another spoiler thread here somewhere. We had no issues on the ITA car with oversteer and made no adjustments to the corner weights or alignment after install. Here's post incident:

Their site lists a bunch of braces and stuff. Which of those are necessary to actually install the front lip? Is it still an affair of simply bolting it on in 2 places on the side and letting it hang there?

Any advice on wing? If you were in my shoes, what would you do? Is the little ducktail spoiler enough or should I go for full on bookshelf wing? I want the car to be safe, but I am semi-afraid of attracting attention from ricers and cops.

We were one of the first ones and didn't use any of the brackets- just the bolts. It last through a sprint practice, qualifying, race and then enduro practice, qualifying and 1/3 the race. I think it would still be fine w/o the off.

What are you doing with car? tracking it? If so, then get another deck lid and mount a wing to that, then just swap it in for the event. Lots of discussion on wings in that other thread. I can say that even the OE deck lid lip spoiler makes down force compared to none, but the ricer wing I put on added much more. Of course cheap wings in general create more drag, but with boost you'll be less worried. And the more down force you have, the quicker you go through the turns.

Alrighty, trunklid swap it must be then.

Also, when seen in person, is the ISC air dam really as hideous as it looks in pictures? I just don't want to become a cop magnet from the uglyness.

I'd say it ranks up there with a wing when driven on the street. But if you're tracking the car you can back up your "rice". ;) Seriously? I think it looks badass:

A good shot above showing it at the max forward point- even with the bumper above. Imagine it with a splitter. :D If it really did bother you, you could always do a nose swap before the track event too. :giggle:

looks like a fake mustache

I actually like it. I think it will look nice with a splitter.

Just waiting for the guys from ISC to get back to me.

And I gotta find a body shop in the tallahassee area that does good work. I see too many donks driving around with horrible paint jobs and it makes me nervous of soliciting the local businesses.

Does it come with it's own underbody panels or are you supposed to fabricate your own?

From the lip base, it comes back about 6-8"- probably for structural purposes as much as anything. The rest is up to you.

Just a quick reminder. This is not intended as a street piece. It's functional racing gear. Pretty don't matter.

ITA rules prohibit it from going beyong the front tires. It also can't be further forward than the forward most part of the original body, so they designed it around them.

I don't think he cares- he's not running ITA with it, and I know the IT rules. :D

I was just explaining some info on the design.

I actually don't think it's that ugly and I'm running it on the street anyway. So long as it's reasonably sturdy I should be a happy camper. There are a few areas in town that worry me in terms of ground clearance, but I can just take the other car if I need to go to those places.

Once I get it installed and I'm happy I'll start ordering up sheets of ABS for underbody panels.
