(IMG:style_emoticons/default/beerchug.gif) Noticed that you want car planted at 30MPH but for really fast times-it neeeeds to be planted at 70.All hypothetical of course.JJackson [/quote] Nows a good time to mention that spoilers usually fit on a trailer easily-splitters require more thought.JJackson |

I know some use big ol airdams with splitters but why not just use an LE style with a splitter? Is it better if it is lower? I know the idea is to keep air out from the underside but wouldn't the benefit of the splitter be more beneficial? That way it would still be able to handle more roads, driveways, trailers...

FWIW I made my front spoiler/dam removable for trailering, which is easy to do. I have 3 different ones. The smallest is an LE-type and the largest is a Sheridan.

Always tired at end of event-just want to pull on trailer. Our new splitter (looks high) is 3 inches off ground 28 inches in front of tire. Our latest was piece from AIR(have to look for it) large squared off piece-we cut the lip off of it.Very well made -heavier piece than I've experienced with other air dams. Will take pix soon.JJackson |

Air pushes down on splitter front and also creates negative air space under at backside-the further back you go the better.Test in mag did not adjust heights (from ground) of splitters.

More than we had in the whole splitter,air dam, and hardware.Could have done it with boards but sometimes already look like the Clampetts. (IMG:style_emoticons/default/sheeplove.gif) JJackson |

(IMG:style_emoticons/default/confused24.gif) [/quote] Ran bolts through original mount points of air dam-ran nut down secure-second nut at back to turnbuckles.Also attached using L brackets at back side of air dam.Was going to run bolt and spacer through splitter to bottom of front trunk-Have not done last one-so far it has withstood some good impacts with no problem.This air dam that I mentioned earlier is heavier made than any I've seen.Broken every air dam I've ever run until this one.Since I just typed that, I think I will add the additional supports.We are currently running "alucobond" panel for splitter-aluminum with resin sandwich-about 1 lb per sq foot-Car really liked that weight there.I'll try to get pix this pm.JJackson |

Be sure to consider venues you plan to run with front spliter design. It was tragic at San Diego to see beautiful cars with spliters cracked, you could hear them scraping all over the place there.
I like the invisble spoiler on the Austin Healy. (IMG:http://www.914world.com/bbs2/uploads_offsite/lh4.googleusercontent.com-433-1306272838.1.JPG) This post has been edited by grantsfo: May 24 2011, 03:34 PM |

Good point. Bumpy/irregular venues are the exact reason I keep all 3 of those spoilers above. I don't use the deepest one if there are cones or large bumps/dips on the course. The LE one was for street use originally but my car isn't really streetable anymore...

And it's great that you can load the car on the trailer without taking off the front splitter. I've got to find someone with one of those long contour bars so that I can get the bottom bit right when I do mine. Given that your using plastic, I guess you could glue on end plates or just bolt them on if you wanted. End plates keeping the air on the spoiler surface have got to be helpful. |

Can you give me details on the swirl fuel tank you got up there in the front? Do you have a smaller pump in the tank?
