Top One Splitter: Functional or just for looks?
http://www.toponeaero.com/front-wind-splitters.html
I am thinking of getting one of these, but I am wondering if they would be functional on the track. Is 1/4 inch plastic thick enough for splitter material? I am mainly interested in these because they offer them for the USDM 94-97 front. Anyone have any input?

Def very weak. It's made out of ABS plastic. I was at Wekfest and TopOne brought out their car. I got to sorta 'play' with the piece and was not impressed. The splitter is very weak as I was able to make it flex by putting very little pressure on it. That was with their supporting rods attached too!! I was going to get it but after that I would rather save up for a P1 Kit.
Supposedly, you can stand on P1 Kit!

making your own is pretty easy if you follow the small guide on the P1 Webpage. You might be able to buy the supports/mounts from them too which is really the hard part of the whole splitter package.
It works very well and the new Airdam design tucks in under the bumper to allow much more usable blade area and still stay within the NASA Rules.

Not to bash on the P1 stuff, but you could probably add some kind of L-stock reinforcements to the Top One job to stiffen it up. A friend of mine used corrugated plastic (like found in political signs all over the place...) with a lot of reinforcement and it actually worked very well for him.

I put back on a very old splitter I made for car this past weekend, I hadnt used it in a while..
Design can play a huge roll in the stiffness of the blade. Mine just attaches to the bumper via nut serts and its not going anywhere unless I start john deering it..

If you attach the top one piece per the directions on the site (all over the bottom of the bumper) it should be decently sturdy. I'm hoping with my brackets I'll take it one step further.
Attaching to the toe hook/area isn't even needed.

i built this and used it. Bought the P1 kit, sold it (reasons for selling have been in a few different threads on here)... modified it buy using nut-serts for the bumper instead of rivets and am using it again. Works great, isn't constantly bottoming out, and is actually "quick release" as i leave it on the bumper and the bumper comes off with 2 10mm bolts and 2 dzus fasteners.
Total direct cost $175-$200 Plus a whole saturday. Probably could get it down to 4 hours now, but that was my first time.

Thanks for the replys guys! I think I am going to give the Top One a try and do some reinforcements to it. I like the idea of tring some sort of quick relase for the bumper to get the car on and off the trailer.
Contact Sport Car Motion. I am guessing you have a Integra by the looks of you avatar. Depending on what year Integra you have there is a splitter/lip combination that somebody sells. I forget who makes it, but maybe SCM will able to shed some light for you. The splitter on their car is not the splitter that comes with it from what I believe. I am sorry I forget the name of the manufacturer of the lip/splitter. If you give them a call I am sure Loi can give you an answer and some leads.
Here is a pic for reference.

The CRX Kit has been a nightmare! but when it's done it will be "Bitchen" It will be done soon as will the new RSX version. Not to mention our Uniqe mounting system.
Some of the mounting of splitters I have seen would take half a day to remove or replace.

You are partly Correct-
The Air-Dam and splitter assembly and the uniqe to P1Spec.(Mounting Brackets) that Loi runs on his Civic and the Integra Pictured ('98+itr) were originally P1Spec. Supplied by me. The only difference is that Loi has found another suitable material to make the Blade from. Oh by the way, we also supplied the Side Skirts as well.
Everyone who buys our P1Spec Kits are advised on the Assembly instructions, or by a personal note from me that -
The Splitter Blade we supply with the kit is designed for use in (Road Racing) and to suit the regulations of the particular class the car is competing in. Customers are advised to take a tracing of the Blade before fitting so they can replace it if it gets damaged at an event. We even specify the type of Ply to use.
My Philosophy...
"In Racing- A Splitter is a disposable item. It should be effective yet easy and cheap to replace. If it should become damaged during a race- It should be designed to break away cleanly. Who needs a Black Flag for trailing splitter debris two laps from the end of a race... Especially if you are leading? And finally- If your splitter is still in one piece after a competitive Race Weekend...You're probably not trying hard enough!" Kiwi 2000
We at Special Projects Motor Sports, and myself especially put all we have learned over many years of international and local professional and amature racing into the parts and products we use and sell. We don't deal in "Bling" so those who say they are sick of waiting for a product to be produced... I'm sorry, I don't care! My first priority is to the racers, not to show cars or street racers, no disrespect intended.
Somewhere on Honda Tech there is a Thread on the P1 Splitter kits with about 1500 or 2000 posts, probably more... I'm very proud that Not One of those posts from users of our P1 Kits or potential users were negative.
And I know for a fact that every single P1Spec customer who has ever called me back after using our Kit on the Race Track has had nothing but good things to say about the improved handling they gained.
I encourage everyone to try and come up with new ideas for splitter blades! I've tried them all, and I'm still looking... I don't want this to become an advertisement, but the product mentioned at the start of this thread looks fine! it will still break! and I doubt that it will hold over 200lbs of downforce without some substantial and complicated frame work that creates even more chaos if the thing gets broken.
For $25.00 I can get up to three blades from an 8'x4' sheet of Hi density Marianti 12mm Ply... Or 4 once we release our 2piece splitter design
So if you want "Bling" or a Racing Splitter for your road car ? please don't bother me.
If you are a Racer, and you want good sound advice from someone who has been around the block a time or two, and probably has as much, or more Touring Car seat time than anyone else on this forum, and can point you in the right direction when it comes to any of this theory... then call me. I 'm not hard to find.

Actually no.... We have the new P1 Spec. Design Splitter and Airdam for the '94-'97 US Spec Dc2 Integra in production now. As used at the end of Last Season on John Hsu's #63 Integra.
It works very well and the new Airdam design tucks in under the bumper to allow much more usable blade area and still stay within the NASA Rules.

I've called and talked to you about several issues with the kit, was told it would be fixed and you'd send me a new lip. We talked about the height the air dam needed to be for people who don't run 17" wheels, and issues with the mounts for my application.
I got tired of waiting (we talked back in may/june last year), so i went back to old faithful.
Tons of GREAT ideas on your kit, the execution wasn't there for me though.
that's not completely true...

The '94-'97 DC2 Moulds are being made right now and I should have the Air-Dams in production in about ten Days.
This is a very poor photo of the Car with the Prototype New style Air Dam but without the Splitter...

Yes, I've been waiting two years for a kit for the CRX. Maybe you should take that as a compliment before you go calling me a show car owner or a street racer. I would love a P1 kit to go with my P-CI wing. I've seen the kits at your shop and really dig them, but yeah...I'm sick of waiting. And since I'm not a "racer," I guess I'll just have to come up with my own set up, which I have using a Top One splitter blade.
