Fadi, the car looks great.
Does anyone know if the GT4 front lip changes any sort of aerodynamics on the Spyder. Does it provide extra front end downforce that would need to be balanced by the rear wing as on the GT4

Yes, it would change the aerodynamics and probably make the car inherently worse without adding downforce at the back. I agree that it looks cool but this mod is probably dilutive.

The gt4 front lip sticks out about an inch , I don't think it's a big difference, and keep in mind at speed our spoilers come up instead of the fix duck tail gt4 one , is it factory approve ??? No but the car didn't change that much.

I doubt it makes any measurable difference for us mortals. It looks great,and the car is as stable as it can be. I will be taking it to COTA in the near future just for fun, and will give you guys a feedback, I had it installed at the dealership BTW.
On my GT3 when I did the sharkwerk exhaust bypass some folks mentioned that it may offset the balance. It doesn't

Not quite a mod, but I just bought two pair of these for working/cleaning on my Spyder.

They work great, though, and plug into the factory lift locations. You lift with a floor jack, then put jack stands directly under them. They are very stable and easy to use.

I am one of the unfortunate folks that didn't get to build their spyder
One of the options I like is the painted roll bar covers
Found a link on planet 9 how to remove it
http://www.planet-9.com/981-cayman-a...r-cover-3.html
Actually quite easy just need t25 torx socket and a few plastic trim pry tools
Only difference from directions above there are two screws that hold front piece on so must pop off seat belt retractor cover first
Will send out this week to have it painted

CAlexio, that sounded amazing! Makes me want to take a road trip across country just to get the same setup done. One question, do any of these changes void warranty, or would you have to reverse one or several components before taking the car in for warranty work? (I know from many of your posts that you're careful to avoid "irreversible" changes). Thanks!

To those interested in the setup, CAlexio is currently running our Sport Header ($3095) and Valvetronic Exhaust ($3295) configuration. We saw maximum gains of this combination at 3600rpm gaining approximately 39whp and 56wtq. Here is the relevant dyno graph (gray vs red).

Who said it was legal?? This is now a sub 4K rpm machine within city limits.. Short shift everywhere. And yes.. When you get underneath the car and watch that beautiful tubing snake it's way from engine block to tips.. And compare to the original setup.. You see how the car now breaths so much better.. And how it can howl so beautifully now. The gear changes are now an event on their own right, there is a bark on each gear change.. Like a mildly contained race car.
The tb and plenum are sitting in a box until I have time to do the install, same with the Cobb. I've enjoyed the slow progression feeling the difference at each step.. With the exhaust side finalized, it's now time to fix Inlet breathing... I love every interaction I have with this amazing and pure machine.

Decided to go with the entire section maybe a mistake but I find the black factory plastic looks rather cheap
Also debated doing seat belt cover and black roof cover that flips chose not to for now but they come off real easy so I could add later and him save some extra paint so it will match
I dropped them off this morning will have back by Friday
So we can decide if it was bad decision or not
Also ordered clear plexi wind stop to finish it off
So my mods to date
3m full front
bolster seat covers
Ipd plenum and Tb
Cobb AP
Gt4 lip
Roll bar covers pained
And famous last words my final mod Kline manifolds inbound tmrw
So should have everything buttoned up by Friday
scheduling a dyno session for next week
Then drive her like a giddy teenager

Agreed !!! I have inconel exhaust on my tts , love it
So had to wait a bit to get them but I'm sure it was worth the wait
Will give a review when I have them in my hands and planning on doing the install myself as well so will take pics along the way
