seems to work fine with the 4.0 dive planes

Viperbob1

Ok... The turbulence of the air rolling over the car hitting the rear wing coupled with the.... No 3M is fine, for you... Note to self, do not get behind Dog.... Wait, no body is behind Dog so all good.

TRAKCAR

Huh, never mind...

I don't know for sure what tape we used but dams it was a bitch to get my Gurney flap off. Never coming of unless you really want it to.

Viperbob1

Oh yeah there are some special tapes u can use. Just standard Lowes 3m is not one. I have used some that wete damn near impossible to get off.

@Deputy: Just get the PORSCHE MOTORSPORT CUP wheel lip spoilers with matching hardware.

They are made perfect for our 997.1 GT3 front end with cup lip and are cheaper than the ones you showed.

I added them to my front cup lip and they compliment each other well.

Get the cup wing after that

Here are the MOTORSPORT parts needed for your front wheel extensions (911slow helped me source the part #s) and you can order them from GMG or any other supplier who can get MOTORSPORT parts.

2x separation edge - part number 997.505.355.90

8x tapping screw ST4,8x16 – part number N .906.487.02

8x plate nut ST4,2 – part number 999.591.699.01

and a few pix of the wheel extension behind the cup spoiler

The wheel lip spoilers have limited downforce. What they do is to make a sharp movement of the airflow around the spoiler. This causes a low pressure area to form behind or at the wheel. This helps to suck airflow from the wheel area to this high pressure zone or really from the brakes in order to aid in brake cooling.

@Viperbob: You are correct bro...... Deputy just added that to his list of mods on this thread. Just wanted to point out an alternative and a REAL motorsport part to the one he suggested.

Nizer

Now the question is how do the wheel lips interact with the RS 4.0 dive planes? Redundant or different purposes completely? Do the dive planes reduce the effectiveness of dive planes?

Izzone

Are the 997.1 amnd .2 parts the same?

Ive heard the same on cooling

I like brake cooling

M3EvoBR

+1... what he said.

Viperbob1

Physics is same for .1s and .2s. Except Dogs. His .1 already registers 5 seconds faster than real time. So this might create black hole or proof of Higgs Boson with his car.

mdrums

I need help with brake cooling....can we fit these to my car?

Dawg thinks his massive trailer hitch gives him mechanical rear downforce!

Viperbob1

I have fit them to non-GT3s before. Your car should not be an issue Mike.

I would like to think I have mastered the technology to alter govt launched gps satellites orbiting the earth, but I'm not quite there yet. Till then you'll have to trust my data.

Centralized additional hanging rear weight gives a pendulum effect thus increasing rear end traction.

Why not just use the sierra composite ones? They're universal, are made of carbon, and are probably less expensive than the motorsports parts. And most importantly, they look cool.

deputydog95

What did they cost? The Sierra ones appear to go higher around the fender.
