In the roadrace forum there are a few posts about making air dams and splitters. What I am thinking of doing is buying some sort of aftermarket lower lip that is lower to the ground than our stock lips to create the air dam and then attach material to the bottom to create the splitter.

I have noticed that some sort of spoon or mugen replica can do the trick.

Do you know where I can find a lip that is relatively inexpensive and durable (ie no carbon fiber)? Where online? What brand? etc. I already checked ebay and didn't really find what I was looking for (unless, my search string is incorrect).

 

Hi David, I've thought of your suggestion too. But I also couldn't find a lip that is cheap enough to start off as a base. So I ended up getting an aluminum strip that attaches to the bumper, and extend down to hold the splitter.

so basically, create air dam by wrapping the lower bumper with aluminum and bend the bottom of the aluminum so you have about 1/2" to 1" to attach the aluminate splitter.

What were your steps?
1. bang or bend lower part of strip over edge of table/2X4 to get lip for splitter
2. wrap bumper and crimp/cut triangles at curves in the lower lip

I read on one of the posts to not attach splitter to air dam, but attach to car. What are you thoughts?

Actually the aluminum piece is straight throughout. But there're bunch of small L-brackets that connect the aluminum piece to the splitter. Then we used 2 more large L brackets to hang the splitter from the rails where the stock tow hooks connect to.

Hmm I'm not sure why people said not to attach splitter to air dam? Maybe they are concern about damages when off track?

 

Dave, why not just order one from Blake at roadracegear.com

He already has it prototyped for our style Integra nose.

 

Ok, I went to the RRG website and didn't see it. I'll send him an email.

 

Dave, PM me your e-mail and I'll forward the pics he sent to me to you.

 

before I sold my car, I bought one from KIWI at Special Projects.. they make one as well..

 

Mark you have any detailed pictures of yours?

 

David - Dug this up out of the archives for you. Andrew made these way back when but I doubt he still does. Part of me thinks he sold the mold to someone. It's a good starting point if anything

His most recent email (2005) = asites@soe.sony.com

^^ That pic takes me back.

 

^looks like a quality piece!

 

RRG
mine has taken a beating this last 1.5 years. what ever you do, make sure you can either remove the splitter or the entire bumper to get the car on the trailor.

I bought mine from Kiwi Also...

I made some revisions to kiwi's kit I use alumilite for the splitter blade and his airdam and brackets... PM if intrested

It's not an ITR, but I used an ebay lip ($70 shipped) and alumalite. The ebay lip is made of ABS plastic so it's stiff, but it can shatter pretty easily. It's kind of good in that if I go off, the splitter will come off and not rip the bumper cover with it. It's . Bad thing is I'll have to buy another lip.

 

So you did not attach the lip to the bumper?

 

The airdam you all are talking about I feel should be attached underneath the radiator support. The airdam/lip will pull the bumper downwards when it starts to work. Otherwise, like Wai, reinforce the bumper cover.

Airdam (vert piece)? or the splitter (horizontal piece)?

I'm not sure what you're asking. The lip is attached with nuts and bolts to the bumper cover. The splitter is attached to just the lip with nuts and bolts. The splitter is not attached to the bumper cover at all. That's the way I have mine set up now.

I should attach the splitter to the frame rails though. I don't want any flex or shifting of the splitter which can happen since it's ultimately attached to the flexy bumper cover.

 

Wai, is your splitter mounted at an angle? I don't think you should see the splitter rake so much. You're probably getting a lot of uncessary drag that way.

I don't think there's supposed to be a lot of force on the bumper and splitter. The splitter should be doing what it's name implies....splitting the air. It should be diverting the air over the top of the car. The splitter itself does't bear the brunt of the downforce. The brunt of the downforce is applied to the body of the car.

 

You answered my question.... thanks!

I saw on ebay cheaper lips called "Type M" or "Mugen-style". Does anyone know if these are lower than our OEM lips?

My splitter is mounted flat. But unfortunately with the small bumper support of the JDM front end, the bumper cover got pulled down as seen in the pics.

I didn't think it would be that much force on the bumper/splitter either, until I see it in the pics! When I checked it in the garage, my whole bumper assembly was strong and tight, so I thought. I pushed it down hard and it didn't move. But when the car was actually on the track at speed, the whole bumper assembly got pulled down so much.

I agree that splitter is there to "split" the air. In addition, it creates downforce by speeding up the passing air below the front. That's why we try to extend the splitter as far back as possible. Same idea goes with the diffuser. When there's a differential in air flowing speed, a force is created (either uplift or downforce depending on direction).

sorry.. never took pics and it went with the race car when it sold..

I checked out the Special Projects website and couldn't find any there either..

PM or email Jeff (username KIWI) and I'm sure he has something since he made them!
