Rear Spoiler Air Brake

[Deathwish]

Has anyone made or attempted to fit an air break on their car?

Im currently in the planning process of putting on on my RB25 GTS-t which has 549bhp, but im putting an RB30 in with a lot more power and brakes can only do so much. Im using hydraulics to raise and lower it, but I want be able to manually/speed adust it for higher speed corners to help with cornering.

I will try to put up pictures when I start the project.

Thanks

Interesting. Have you drawn your designs or just see how you go? I guess it will need some sort of fail safe, if your really depending on it to supplement braking into a corner and it doesn't activate, we'll you know. I think it's inherent design should be on/open (as in activated for braking) so if it fails it slows you down rather than doing nothing. Now having said all that are you sure that the time and money involved isn't better spent on say tyres suspension and brakes.?? Plenty of really fast cars get by without these. Also these can be bought of the shelf.

Good luck

I actually wanted to do that for my Uni project. You can either write a programm that would sense changes in G forces to activate it in terms of lifting it up when cornering. Another option is if you can get access to the circuit that triggers the brake lights you could put hydraulic pistons that would be lifted when the brake lights are engaged. When you disengage them you might need some sort of digital capacitor with enough voltage to drop the spoiler down after you let go of the brakes. As for higher speeds if you have a digital speedo you can log the circuit to open once you get to that speed.

The reason why i dint do it was the cost. You could spend that on a crazy big brake setup and custom suspension work.

P.s you might want to calculate the drag coefficient that your air brake might create and see if you get much stopping resistance out of it. But otherwise or the satisfaction of designing that would be awesome.Defs you should have some pics man.

Well im going to be using a small 2 ram hydralic system that was originally off a small convertible car. Im still in two minds as to wether to use a large flat (bootflush) drag style spoiler, or the high drift style type. Someone mentioned about using a pressure switch on the brake pedal. The sysrem from the caor uses a two way 3 wire switch that raises and lowers the roof. Im thinking of using a lever to raise it faster. I'll try and do a drawing of what im looking to do with the bits i've already got. Been thinking of doing a similar system for a front splitter which would push the splitter forward and down at speed. It would help with speed ramps too as my car is pretty low and catches most things on the road.

The system only weighs around 8-10lb, the pump is about 3" diameter and 8" long.

make sure you do a lil documented project it could turn out to be really good.
