I feel your pain on the 3.91's. If I could do that over again I would probably try 3.73's.

This was a good read. Not too often you come across someone willing to put money into a GTO suspension for racing purposes. And I could care less about drag racing.

I sold my 04 in search for a more plentiful(and therefor cheaper) aftermarket and "cheaper to maintain" car. So I drive a 95 Z28, and have loved modding and racing it.

I loved the GTO for the power and comfort. Almost ate someone's bumper in a "oh ****" braking moment with my stock 04 brakes. I'm kinda bummed that everything I did to my GTO was to "fix" issues, and not really to improve it.

Great write up! Sounds like you have a great combination of power, weight, and handling.

Now time to upgrade the steering wheel, that will help make the car feel even better.

The car looks great and I bet it's a blast to drive. Glad we could be a part of the build and hope you like the axles

Thanks
Chris

Chris!

Yes, thank you for all of your help and patience over the years. I LOVE my GF axles and your pinion seal saved my bacon back on the old housing. Hope to someday own a CF DS from you guys when my stocker finally dies a warrior's death.

The car is a blast to drive. It is like a C7 Sting Ray with an extra 180hp on tap at all times (same curb weight too)

Thank you everyone for the compliments. My time and driving instruction at TWS this year did more for my driving abilities and this car than any single mod alone. I am very happy and I hope this little motor lives a long, adventurous life.







-Michael

Upcoming winter mods/finalization:

-Install HID lows and fogs that have been NIB for the last two presidential elections...

-LED lights throughout interior and trunk

-Acquire new stereo head unit and speakers (stock Blaukrap finally let go)

-Acquire traction... (285/40 NT05Rs)


I miss you 1st gear! Hope to feel you soon...


Stay tuned!

Awesome story. I graduated with my bachelors degree on 12/12/15. I'm 27 years old, so I'm right there with you. My Camaro has sat patiently for over a year, unmodified. For my graduation present to myself, I bought myself a roll bar and shocks/springs. I plan to do a few track days this year at VIR, here in Virginia.

So is the 640 crankshaft hp? Didn't see any mention of a Pedders Fastrack, are you running one
Looks like we are running similar suspension

Yup! You deserve it! Suspension mods are yummy. Get to feel it every time you drive, and it will protect you on bad roads with ruts and pot holes where a soggy, OE suspension would otherwise bottom out and rub tires to fender.

VIR is a mean track! Get some good brakes and go have some fun.

640bhp. Made 541 at the tire. See original post.

No fast rack here. They were extinct long before I got serious about corners. People now ask $2-3k for used, dirty Pedders Fast Racks.

I would rather have a smaller, sportier steering wheel myself. The new suspension, alignment, and wider 255 front tires really did wonders to tighten up my soggy steering. Nothing like a German car or a C7 in the steering department, but much improved for an 11yr-old Aussie cow.

Gonna do a nice video this year showing the build, the blown LS2 that shat itself, and Porkchop's rise to current power.

Put a hurting on a 650whp Paxton S197 Mustang with a H/C/I 302ci last weekend. Door to door runs in 38* weather until the Stang finally broke!

Helped him fix it on the side of the road after, because I'm a good sport. So many good Ford jokes that night...

For now, enjoy more pictars...

Have you ever considered a mini-tub in your quest for the elusive concept of traction? I'll be rolling my fenders soon, but have been kicking around the idea of doing a mini-tub down the line

-Corbeau Forzas with microsuede option
-Custom GTO brackets sold by Corbeau
-Stock seatbelts and airbag harnesses retained.

You wouldn't believe the steal I picked these up for in brand new condition... (I'm poor so it was the only hope in hell I had) Seats and brackets purchased new at half price. Right place, right time scenarios.



Seats gained me 2" of much needed head room (helmet real estate for race days!), and put my fat 220# *** lower in the car to promote even better handling.



The stock seats in a Goat are nice but weigh 70# each and feel like you're sitting in an SUV. They're so high that you hit your head on the A-pillar very easily during ingress and egress. Corbeau seats were a smart upgrade and are responsible for 94# of the car's wight loss.


Amazing thread and write up! I miss my 06 GTO

That OTR cai is the sexiest piece ive ever seen!

i wish my 05 CTS V had enough room for something like that!

Now you just need to ditch the factory steering wheel and you will be set!

Swede,

Wish you were local! You could ride in my car around town and feel what I mean. These cars have a ton of suspension failures with bushings and strut mounts that affect safety and tire wear, as well as braking performance.

I HIGHLY encourage any GTO owner (regardless of their performance pursuits) to go through and have the chassis inspected by a competent mechanic who knows these cars and what to look for.

Front radius rod bushings, front strut mounts and bearings, and rear x-member bushings are great starting points. The stock front endlinks are usually toast by 50-70k miles as well.

Focus on this and improving the weak factory braking setup and you'll be on your way.

Engine power is easy, but it's wasted money if you can't safely turn, stop, or put the power down! Best wishes to you. Shoot me a PM if you ever have questions or need help with a project or build route.

Funny how many people are ******* on the crappy stock steering wheel...I never liked the stock wheel. It's big and not very sporty. I just kind of accepted it. If I find a good deal on an HSV wheel I will jump on it!
