Hi everyone,

I am about to finish my project so far I ordered below for the track use:

Enkei RPF1 17x9 +35mm wheels

Nitto Nt-01 R Compound Tires 235/40/17

Fortune Auto 500 with Swift Springs (9k/9k), Radial Bearings and Extension Upgrades

Custom Brake Ducting

OEM Oil cooler

OEM Camber Bolts

Grimspeed MC Brace

Koyo Radiator

Perrin OP

Invidia FP

Stoptech Brake Pads ( yeah I know)

Front Lip

TRD QuickShifter

Soon to be ordered :

Kraftwerks Supercharger Kit
Ecutek and Tune
Raybestos ST-43 pads with matching rotors (after it becomes a necessity with FI power)
JDM underpanel (if it really works)
Lightweight battery
Perrin engine mounts (if I don't like the shifting feel after KW)
schroth 3 rallye harness ASM
Affordable Hans device

I also would like to improve the aero and reduce the drag as much as possible so I searched but couldn't find a descriptive thread about the aero parts and their effects on our cars (other than the visual mod threads)..I don't really care about the looks, stance ..etc..

My car is BRZ Limited so it comes with the rear spoiler and I am not sure if it's functional at all.. I want to improve the high speed stability so I also added this part to the list

I am on the fence of adding an extension to the front lip like my friend did to his MX-5 since I believe it will improve the air flow for the brake ducting and reduce the lift.. In his case it's believed it has a positive effect when it's combined with a big spoiler.. We know a local guy who can fabricate a custom abs lip like in the picture below

So, for those who invested in aero parts, my question is did you ever notice any increase in stability after adding a bigger lip( possibly with rod) or did you see some negative effects of doing so?

Before adding any other aero parts to my list (canards, rear diffuser ..etc) I would like the hear your experience with them. Since the car will be FI pretty soon, high speed stability is really important for me and the last thing I want is to hurt the car's stability ..also I learned that in some cases adding a bigger front lip also requires a bigger wing to compensate the added friction in the front end or tail happy feel.. I am also debating to get this JDM underpanel but not sure if it really helps reducing the air drag

Any input would be highly appreciated it..
