The part number for the APR splitter for AP1 with OEM lip was actually created from a template off my car so what I have on is actually the first one they ever made of it. Jeff (minitoyota) installed mine but basically it's held up with something like 15 bolts under there and I have the support rods there just to help it from sagging (it's a pretty solid piece as is). It's just connected to the bumper with washers on both sides. It does pull on the bumper a bit so it's stretched a bit there but it's been rock solid whether I'm doing 120+mph at the end of a straight at the track or if I'm whacking cones at 60mph at an autocross.

 

the way steguis mounted the support rods are so much better looking than a pair of vampire teeth sticking out lol

 

Thanks man :thumup:
I got mine installed today by evasive motorsports. They did a fantastic job at mounting it and came out looking great. Idk if it's just me but I can feel a difference even at 75mph on the freeway. They used all original mounting holes underneath so no holes were drilled on the car. Ima try to mount it later on differently because I rather have it be pulling the car down from the chassis and not the bumper.

Steguis: Do you see a problem running a splitter without a rear diffuser or a wing?

Here is a pic of mine from today

 

That looks very good.

 

In short, I think you'll be fine without a rear wing but...

There are a lot of factors at play. With a front splitter you will get more front end grip at around highway speeds and higher. If you're turning at high speed, then your rear may give out before the front making the car feel more oversteer prone. However if you're running staggered tires, then it might not be a big deal since you'll have relatively more grip in the rear to begin with. Suspension setup and aero is just one giant balancing act. For reference I run a square tire setup (255s all around), have a bit front sway bar and no rear sway bar and 800f/700r springs.

 

Yea I totally noticed a difference on my way back home how much more planted the front felt while driving 70mph on the freeway. Kinda felt like my rear was lifting but that could be my mind playing tricks on me. I'm currently running 17x8 17x9 +45 with 225-45 f and 255-40 rear. I'm on stock suspension currently but will soon be getting coilovers. How's the ride quality and if you don't mind me asking what kind of springs are you on?
Lots of great info thank you steguis.

 

The ride quality is great but the caveat is that I'm running Moton triple adjustable shocks so it has no problems controlling springs this stiff. They are eibach 6" springs with helper springs.

 

Bringing an old thread back from the dead with a question...how much does the splitter weigh?
