Redundant. Front lips are like splitter wannabe's.

Having a lip in addition wouldn't have any additional benefit over the splitter, but may complicate mounting. This would be determined on a lip by lip basis...if you will.

Sorry I haven't updated this thread lately, Wasp has been caught up with some local noise complaints. Apparently making carbon splitters during daytime hours is loud? *sarcasm*

Giving it some time, I wouldn't want to take any orders that can't be filled at the moment regardless

Do you know if they are going to offer different "levels" for the splitter, like how they do for the s2k?

Yes, I believe he will offer a street version as well, in addition to a "lip protector" style lip.

As a small update, here's some photos of the splitter OFF the car compared to APR's offering for the Evo X (Sorry we didn't have an APR FR-S splitter on hand)

Sorry the photos aren't very good, I took them with a potato

Let's not forget that the load being placed on that splitter material is not the direction of the load being generated by the splitter

The Wasp stuff is definitely strong, but I haven't heard of any APR splitters snappnig on the freeway or track either.

You might want to compare race application to race application. Here is APR's Nomex dry carbon honeycomb composite splitter material. Nomex honeycomb is fire retardant and also FIA approved material for race cars.

Lets be serious... those honeycombs are ridiculous $$$. Not even the same league.

Very interesting. Do we have any more information on it yet, including weight, drag force decrease, downforce increase (both front and rear) and aerodynamic balance?

Also, what is the mounting process like? I am assuming holes have ot be drilled in the crash beam for the four mounting rods, any other holes that have to be drilled?

As far as weight goes, since you're removing the underpaneling in front of the metal skid plate, it just about evens out. I'd say, if anything, there could be a pound or two variance max counting the support rods.

With that out of the way we do not have access to a wind tunnel, and quite honestly CFD analysis can only tell so much. For example, it does not account for any flex in the system. This splitter will not flex as it is chassis mounted, however I do recall another FR-S specific splitter that did have a CFD analysis done and it did show some improvement. What it didn't account for was the fact that it was mounted to the bumper cover alone, and any downforce it was creating was merely pulling down said cover, not actually pulling the chassis to the ground. So no, I could not reasonably give any specific numbers without it being a complete guess, as a wind tunnel is the only real way to get such numbers.

Finally, by feel alone, I can tell you that if you're not going to be beating the hell out of the car at the track, it will not be absolutely necessary to add a wing. It would help a lot, but under those conditions it does not upset the balance *too* much. If you are going to track the car, especially on a higher speed track, the balance will be shifted enough to the point that a good wing will become necessary.

Do the four the support rods clear the plastic bumper without modification? Do the side supports clear fog lights, washer reservoir, or possible coolers?

Any word on the street version?

You say the wind tunnel is the only way to get such numbers but that is completely false and misinformation. One big misconception of wind tunnels are they reproduce what the car will see on the road or track. This is false because wind tunnels only simulate the conditions on the road or track. Simulations inherently deviate from reality and it is often hard to quantify all the sources of error. Wind tunnels idealize temperature change, wind boundary layer, wakes of other car just to name a few.

Sources of these inaccuracies include; the rolling road systems, wall effect (tunnel sections), tires (shape from deformation), cornering conditions (steer and yaw), sting interference, wheel lift, and model is not actually moving (relative motion isn’t the same). Wind tunnel data is precise but saddled with inaccuracies. Road data is free from the inaccuracies but are not precisely measured. Anyone who will quote you extremely accurate numbers from a wind tunnel is trying to sell you something.

Also on CFD analysis, I would be careful saying what it can and cannot do unless you really know. CFD can in fact account for “flex” (deflection) in the system. Some programs need to be coupled with another program to do this, but saying it doesn’t is completely false.

Also, this "other" splitter which is solely mounted to the bumper cover is again false. It mounts to a structural support in the rear. Yes the street system deflects at high rates of speed, but for the street (sub 100 MPH) this is perfect. If it is hit on a curb, or going up a driveway, the splitter will deform instead of cracking like a carbon fiber piece. Even though the splitter is deforming, the forces transfer through the car, they don't just vanish because the bumper cover moves. Instead of going directly to the chassis, it travels through the bumper into the radiator support, which is structural. On top of that, if the user purchases the race upgrade, this directly connects the front lip of the splitter with the chassis. Actually the same mounting points were chosen by Wasp. So when you say it isn't pulling the chassis to the ground, this is false for both the street front splitter, and the race upgrade which is then chassis mounted at the front and the rear.

Please do not spread false information about other people's products or false information to the general public about CFD and wind tunnels.
