Softening up my GXP

[Doug Hilliard]

I do have some eibach's sitting in my garage that need to be put on....

Come on up! I need to hear your exhaust again anyway! Only thing is, I don't have spring compressors so you'll have to provide those!

Kevin has em lol. It will be a nice change of pace instead of working on Mustangs lol. Although changing springs on the rear of the Mustang is 1,000x easier.

I LOVE reading these things. Not because I like to see you go threw it, but because it allows me to contemplate what direction I want to go with my car.

I think Livernois uses a different rear axle "Driveshaft Shop" if memory serves. Andy told me they had better luck with them on the G8's. May want to look at those too.

You could look at a complete Corsa system for your car. They're NOT cheap, but you don't go cheap.

He has American Racing headers. He's only looking for the axlebacks, no need to hack up an awesome setup.

Btw, if you want some help with those changes, I've just reorganized my garage and it's clean, organized and roomy! You bring it over and we'll go at it!

Once I have things to do, definitely! Right now, all I've got on hand is the shifter mount. The axles will have the car up in the air for a few weeks, undriveable. So the best thing to do in your garage is the shocks/struts. I'll keep posting up, so you'll know when that's closer. We can definitely make a time of it.

Well the good thing is your new ST is supposed to be a pretty good track car out of the box. Maybe try that in an HDPE and use the GXP as a tourer/pleasure car. Not saying to mod the ST because that is now your DD, an awesome DD, but a DD nonetheless lol.

The coworkers I went to the track with last weekend told me I should have taken the ST for the fun of it, since it's such a small, tossable car that came with sticky tires and has grippy Recaro seats. I definitely will take it one of these events! It'll need to be somewhat cool outside, however, since turbo engines can suffer crazy-high oil temps.

I know what you mean about the ride with your setup. Mine is definitely unforgiving at times especially with the SRA, but I love the way it handles too much to change it lol.
I may change to some Viking adjustable or QA1 adjustable for the strip.

And that's always the trade-off. But the G8 doesn't spend enough time on the track to be worth optimizing for the track. Especially not when it's a 4000-lb grand tourer.

Really, it still makes a lot more sense to save up and plunk down for a track C5 Z06 or Miata, since they can be had on the fairly-cheap.

I'd be willing to hang out and lend a hand as well. We need to have another G2G.

Sounds like a plan to me! I even now have a propane forced air heater if it's cold out to make it more comfortable!

I haven't even started doing anything yet, dangit! This is all just planning!

Ah, now that's something we can have a get-together for. I do have spring compressors, and I can pack up and bring air tools. If at all possible, Troy, if you still plan to pick up the FE3 shocks, pleeeease do so before we put the springs on. I'd prefer to have to do that job just once, and retain the right to refer you to Performance Chassis for Round Two.

That's why I posted this thread. That and so people can weigh in as I go.

Actually, I was on their site earlier looking for the anti-wheel-hop kit. I should contact them and see what they've found and why they carry that brand.

The same reason the American Racing Headers system rocks is the same reason it sucks: it's a full system from engine to axles, in need only of axle-backs. So if I get a Corsa cat-back, that unfortunately means I'm looking at fab work to get the Corsa to attach, and I'm removing pieces of a system I paid for. So I'm stuck with axlebacks, and Corsa doesn't make just axlebacks for the G8 anymore, if ever they did.

[Chewy]

I hear ya! This is why I went Kooks. I REALLY wanted ARH for whatever reason, but I wanted the Corsa more. You honestly lose very little power going with GXP mufflers over your MF's. The killer is the price of them and the weight.

I don't get any drone with my OBX + Js, but then I have catted 1 3/4" ARH, and an L76 rather than LS3. My Js are the Solo adjustables though, so I can tune them just right for my ear.

[GXPaycheck]

Hey Kevin, I picked up a shifter gasket that is supposed to fit the G8 and get rid of some of the vibes. You are welcome to try it out.
They are cheap and I can get another one. CobraBob says it fits the stock shifter. Might fit the MGW.

And you are welcome to try my magnaflow axle backs. Might give you an idea of which way you want to go.

The problem is that I need multiple J-pipes on the Magnaflows. They have a nice, deep tone. But the downside is that they resonate too strongly at low RPMs. So the J-pipes are currently set up to quell drone at about 1800 RPM. And they certainly help. But it's still loud enough to be annoying.

It will fit the stock shifter where it connects to the body, and it should do the same for the MGW. But I want to try the MGW bracket solo before I add any more padding. The Stang Shifter Bracket softens the mount point to the body and will allow some slight movement in the mount itself, as opposed to rigidly connecting the mount and then use bushings within the mount (which is what the stock shifter and the MGW shifter do).

Magnaflow is actually what I've already got. Which actually makes me wonder...

I'll have to check and see if Doug has his old GT axlebacks.

Flowmaster is another option, actually.

And I also just put in a call to Solo Performance. We'll see what they say when they call me back.

Also, been meaning to post this, here's MGW's new rear bracket. Video says it's for a Mustang, but the bracket works in the Camaro/G8 as well.
