Amuse Wing to APR?
 

Hi,

I'm thinking about switching out my Fly1 CF Amuse wing to an APR wing because I've heard that it has better function, so I've been toying around with getting the GTC300 or 250 paired with some custom front splitter / rear diffusers.

Does anyone know how well the APR wings do in terms of DF vs Amuse? or had experience with both on the track?


Side note: Amuse wing would leave a lot of holes.... would it be hard to patch it up

Unless you are serious about tracking your car and you actually need the functionality of a GT wing then just stick with the amuse wing. You would have to patch all the holes in your hatch left from the old wing and repaint the entire hatch. It would get pricey.

^^^Agreed! I switched out my Nismo wing for APR GT300 and had the holes patch and painted. It looks great and very functional on the track. If you got the cash then do it. I would spend money on your suspension and track time if you are just starting to track.

So I actually just swapped the same coloured base hatch with someone else who wanted to buy my amuse wing and installed the APR wing which was convenient and no cost. However I'm getting a little more understeer than I would like now even at 0 AOA..

Do you have any aero up front? If not add some to balance out the rear.

He has an EVO-R lip.

have the EVO R lip right now, cooltoy knows everything :P

but I have an amuse bumper coming in a couple months (or whenever amuse decides to make it), and probably adding an aeroblitz splitter or a custom made one to try to balance it out. there might be things I could do with the suspension in the rear too, or maybe more neg camber for better turn in

Do not put a wing on the rear unless you have a splitter and canards in the front. Because you will load the rear and lift the front at speed.

Don't even bother bro.. those splitters will not allow you to go over 100mph

yup.. experiencing that right now, will be an interesting day at laguna seca next week..

my friend said my car looks like it squats whenever i accelerate

know any splitter that would? or have to be custom

They all squat when smashing the loud pedal. It's when you start to get up over 50 mph that things start to get interesting. The faster you go. The lighter the front will get with a wing and no splitter.

Down force from a GT wing versus a single element cosmetic wing is large.

The 09-14 nismo wing generates something like 150 lbs of downforce, i read that in an article a while back but can't find it anymore. Versus several hundred lbs of downforce generated by a GT wing. I've known people who have had to reinforce their hatch and had to put padding over the rear tail lights because the downforce was pushing the hatch down so much that the lights were cracking and the hatch was beginning to buckle.

Like everyone else said, don't run a GT wing without a chassis mounted front splitter. You won't be doing yourself any favors.

yeah sounds like the general consensus in this thread, I will probably only hit up one more track day until the bumper arrives, splitter's made and maybe canards

:iagree::iagree::iagree: I was just at ZDAYZ and discussing this point with another go fast brother as my paint has cracked on the hatch due to the force exerted on it. I will be reinforcing the hatch this summer lol!

Also, at above 100 mph even the Nismo wing quits producing downforce. To optimize downforce you need to lower the car at least an inch to 2 inches as well.

Since it was brought up, where and how is everyone attaching their front splitters? I'm guessing most use the front bumper but has anyone mounted theirs to the chassis in any way, shape, or form? ...and I'd so, which splitter and how since the majority I see are APR (pics would be great).

I have installed a couple of Next Level Performance Splitters and have custom made one on the car. Mine is mounted to the front bumper as stated and then it is mount to my Zspeed under tray. I sandwich the back part of the splitter between the frame and the under tray bolt back edge of the splitter to the six bolt slots on the front the Zspeed under tray that would normally attach to the oem under tray. It a very solid fit. You still need splitter rods up front because under braking or just lifting at high speeds, the front end of bumper will flex downward and the splitter and the front bumper will damaged. Yep, ask me how I know lol. I don't have my car right now so I can't take any pictures for you.

I have the ZSpeed undertray as well so I think I have a rough idea of how you have it mounted. What did you mount the rods to? I got rid of the front crash bar since I'm running Admin intakes and Z1 filters/velocity stacks and have the FI tow bar instead.

Also, thanks for chiming in. I really appreciate it.

The splitter rods are mount through the bumper and a rectangular piece of aluminum is used as backing plate to add strength and rigidity.

Bobby, when you do this stuff. please take pictures. :tup: Because, I'm interested too on how you did this.

Copy, that I need to be more engaging in that way!

When I get my car back I take some pictures of my setup.

Ouch, yeah without the crash bar in place its much harder to mount that splitter to something more solid than the bumper.

Yeah... I've been looking at bar clamps thinking that it may be possible to use that and mount one end of the rod to the tow bar and the other to the splitter. I found a few that should suffice but I need to get a look at the ends of the rods as well as their length to be sure.
