Spring mods = Porsche GT3RS killer!

And so it begins...
Custom fender flares, 305s in front on 10.5” wheels, 325s in rear on 11.5” wheels, camber kit giving -2.5 camber and new ECUtune, high flow cats, 3” exhaust, carbon intakes giving 650hp. And still very streetable.
BC Forged will have my custom wheels made in about five weeks. Will have all the rest of the other work done by then. Should be a fun spring for me but I imagine a lot of expensive two door sports cars owners are going to be pretty shocked at the track!

Love it. Ride it hard cugine. Where did you get the new intakes?
the fronts are flared already?, its hard for me to tell because of the color and reflection from the shop lights.
would love to see how they came out, I'm sure getting more meat on the asphalt will help the cause.
also are you going monoblock or modular?

Thanks. Should be a she-beast! Don’t have the intakes yet

Oh no just getting started!
The photo of the front wheel is with 5 Lugnuts put on the hub to simulate a 21 mm spacer then the wheel put on there to simulate approximately how far it will stick out. But actually it will be another 4 mm out than what is shown.
The photo of the rear is a Corvette wheel just held up there my tire it will be the same size as that tire but it won’t stick out quite that far we couldn’t fit it over the lug studs as the pattern was different
Flares will stick out about 2 1/4 inches when done. They will be made out of metal and finally finished I think I’m going to Hydro dip them to make them look like carbon fiber.
They will also have a chip guard in the front and mud flap in the back incorporated into the design to help protect the side body panels.
Monoblock wheels

The mockup for front flare. Looks about the right size. See the built-in chip card and mudflap to protect the lower body.

Hello to you too... how are you?
It will be a 300 cell high flow cats 3 inch diameter directly to a Remus 3 inch diameter exhaust.

Hi, lol, sorry, just a fan :)

I've seen Eric's post and his qv is impressive, but I'm curious, what made you choose remus, and also a 300cel vs 200cel.
Looking great. Can't wait to see your completed "she beast".
By March 16th my new BC Forged custom wheels should arrive 10.5x19 and 11.5x19 to be mated to 305 and 325 width tires, can’t wait!!
Regarding my fender flare project it’s been changed a bit.
After we painted the mock ups black and took it out into the sun to take a look at it.
First impression when we put those big wide tires in there it’s gonna look great!
But we also decided that the fender flares are just too wide to do only the flares.
Instead we decided to do a mild widebody ground effect kit instead. Basically were just going to bring the front flares out into like dive planes so I’ll get more downforce and tie the front flares into the back flares utilizing the existing side body and then fill out the back ones too. Like the photos I am showing here. And of course the finished flares will be much smoother and less angular than these mockups. The one photo outside with the flares painted black kind of shoes how awesome it’s going to be once fenders are filled in with wide tires.
Should look really smooth. We are trying to hard to keep this car extremely beautiful and also be functional at the race track with the materiality wider tires.
Big shout out to those who has been helpful and in understanding that this is a process and a compromise.

hope the fender flares all work out for you. The wider tire set up and ideal race upgrades should be huge improvement at track. Curious to see the times you put up. The GT3 rs is a very formidable opponent. it’s better or equal to mclaren 600lt on many tracks.

Some people don’t understand tracking or modding a car to make it go faster. Look at the title of this post for therapy.

Thanks you know about Ideal Racing, modding and which cars are fast at the track. I wish everyone on here was as qualified as you.
Stock GT3RS is [email protected]
my modded Giulia QV is [email protected] to 650hp.
So I’ve got my work cut out for me.
Both cars have excellent suspensions, brakes and are well balanced so it will be a battle!
Modding a beautiful car to be faster at the track with wider tires and stay beautiful is a hard mod. And as I’m sure you know sometimes you make compromises to make both work.
And would it be boring if no one did anything special with their car?
Or how about a “family sedan” that can whip ass on a $300,000 2-door sports car! LOL

I would suggest looking at the alfa montreal group 3/4 racers as inspiration in refining the visuals.
Although I'm sure many consider those to be sacrilege - but purpose speaks for itself.

I’m working with some other people in other forums that are quite helpful. In fact the lineup photos were done by someone there.
It’s funny one of them sent me this Montreal photo I believe that’s what you’re talking about. The other photos were all sent to me by other helpful kind people Who understand this.
But it’s funny these many people are sending me lots of widebody pictures and pushing me to go full Liberty Walk type huge body kit. And then like you say other people are upset I am at modding my car because and they don’t understand how I’m not doing it for looks or they are there just common haters of anybody who does something different than they would or could afford to do.
If this mod turns out right it could be something beautiful too. Certainly will be unique because nobody’s offering a widebody kit. And the only Giulias I have seen with wide bodies are either just computer renderings or full on racecars. I’m just doing a moderate widebody and ground effects mod.
I’m sharing this on this forum because I know there’s some people who appreciate and enjoy looking at the process and who understand it. And also for the people who understand the tracking ability of this amazing car

What happened to that measurement you made and posted that came out 3620 pounds? I was assuming that you had taken measures to trim the weight of your car to get it that low.

That weight figure must’ve been from years ago when the car first came out and Alfa didn’t even release wet weight figures.
Now there’s several sources that say it weighs a little less than 3800 depending on the brake choice.
I haven’t done any weight reduction actually when I went to the Girodisc steel rotors I gained about 45 pounds.
I don’t think there’s a lot of weight reduction you could get out of this car. Talking to my Alfa technician the rear seats don’t even weigh that much. Although I have thought about replacing that large lead acid battery with a lithium one. You probably could save 50 pounds right there!!!
Although personally I’m fit my car choices seem to get heavier and heavier!
In 2016 I bought a 4C [email protected], in 2017 a Giulia [email protected] and just last week a 2020 Stelvio [email protected]
But what the hell all of these Alfa models are a lighter weight than their competitors.
Kind of cool to own all 3 of the recent top Alfa models although the 4C needs body transplant LOL.
My dealership and also Alfa USA take really good care of me and the cars have been reliable and especially since I track them hard.
FYI I put lowering springs in the Stelvio and dropped it 2 1/2 inches. Plus I have my Giulia QV OEM Tecino wheels that I’m going to use as track set up wheels for the Stelvio. Tge Tecinco wheels and the tires I put on will drop it another 1.4 inches plus a lot less wheel/tire weight. That’s pretty exciting drop in COG and of unsprung weight.
Dropping the car really transformed it into a hot hatchback.
Can’t wait to track this Stelvio soon in about a month when the tracks open. I think it’s going to be stupid fast.
But the Giulia QV will always be 500 pounds lighter so it should be faster and with my new mods i’m hoping it will be a real screamer, something hard to touch with most any car.
Here’s a couple photos of the dropped Stelvio QV

I would not worry about what other people think. It’s your car, you’re money and you drive it hard. Most alfisti or car guys should respect that even if they disagree with it. A lot of people by a fast car and never drive it above 80 mph or try to get 25 mpg in A mode. Better to die on you’re feet than live on your knees. keep Driving it hard.

You’re posts are very helpful. I’m not a fan of some of the wide body kits but we know it’s important for what you are trying to achieve on the track and still keep it street able.

Looking forward to seeing what you do to that stelvio. I’m not into hot hatches but I think alfa really missed a big opportunity to introduce a focus st or civic type r competitor. That IMO would have absolutely catipulted the brand in America when every 18 yr old suddenly becomes an alfisti. The marketing would of been huge. So since alfa failed to make one we will just rely on you my friend. No pressure haha
