Default C6 Base to Z06 wide body conversion parts?

I am looking to wide body my base model C6. I know some have said to use factory Z06 quarters and fenders but they are not easy to find, or I am not looking in the right place, and I want the rear quarters, front fenders, and bumper asap so I can keep my project moving forward. I found this company by the name American Custom Industries (ACI) out of Sylvania, Ohio. They claim to have been around since 1968 and specialize in Corvette fiberglass parts. I figure if they have been around that long, they probably have the fit and finish down by now, but I don't see many reviews. Has anyone used their body panels? Any recommendations where I can purchase body panels? Thank you

Dino’s has front fenders and maybe everything else. I didn’t check. These are reproductions and I personally don’t know how good they are. https://www.corvettesalvage.com/prod...set-2005-2013/ Keep in mind you’re going to need a bunch of other parts like front and rear wheelhouse liner sets. I recall seeing a forum member’s thread that listed all the parts that you’d need. Maybe a search would find it. Maybe I saved it in my PC.

I did the rears recently. I used the ACI fenders they fit very well. You're issue is going to be finding the liners and the brake ducts and the mud guard flares are very expensive also.
I didn't do the fronts and I have zero plans to do so. Whole rear conversion including wheels/ tires and paint was about $5000. Likely be over $10k doing the fronts and rears and at that point you'd be better off just selling and buying a GS imo (unless you have alot of mods in your car already).

Functionally, I only need the rears to fit wider tires, and you make some good points regarding cost. Your car looks good with only the rear being wider. I may go that direction. It’s good to know you had good luck with ACI. Thank you.

I am unsure as to which way to go now, wide booty (z06 rear quarters only) or Z06 quarters, fenders and bumper which cost obviously more. I will absolutely need the rears for wider tires for grip (widest possible) so rear quarters are a must, but don't really "need" the front. Aside from aesthetics (some liking and some not liking the look) are there any disadvantages of only doing the rear (i.e potential understeer, etc.). My primary use for the car would be a daily driver that I could run some at the strip as well as road race at Sebring periodically. Approx HP would be 1000whp. Not sure what the max tire sizes would be that I could run if I only did the rear quarter panels. Looking for any advice. Buying a Z06 or Grand Sport is not an option. Appreciate any input or experiences.

I’m in a similar boat. I really like the aesthetic of the wider rear arches but the handling aspect is a consideration. Buying a wide car though, getting hold of a GS or Z06 isn’t an option, I’m in the U.K. and finding the car to start with wasn’t easy. I assumed sourcing the rear fender panels of a front end collision car would be pretty easy?

I am starting to hear horror stories of several not being able to get the inner fender liners, and the cost when you do find them is more than the cost of the fenders. The rear isn't too bad, and watching a lot of YouTube videos, it looks like you can do the rear quarter panels cheaply (less than $1000 for both rear quarters) and you can keep the rear inner liners and fill in the gap easily where it is not really noticeable. It seems the front is the issue; besides the fenders, you need the bumper and inner liners which are not easy to find and cost more than the front fenders, and it doesn't look like you can modify the front inner liners like you can the back. I know

I am doing the rear quarters for sure. I am wrapping the car, so in the future, I can always do the front, but I think I will look for the wheel well liners and bumper first, and when I have them, I will then purchase the fenders and just get those parts wrapped before I install them. I'm still concerned about the cornering, but I guess I will just have to feel that one out. I need the grip in the rear, so not going wide in the rear is not an option. I feel sorry for the Grand Sport and Z06 guys who need to replace their own fenders with all of us base model guys out there also looking for them.

Doing some quick research, so others with real life experience may say different but it would appear the difference in the amount of wheel pushing away from the body is around a 1” up front, the gain toward the body is minimal. The rear is around 1.75” and 1/4”. Looking at the car an additional inch would fit, albeit with aggressive fitment and likely some modifications to the inner arch.

Well, it’s ~$2000 to get the front fenders and bumper wrapped again later (if I decide to do this later) which is about the cost of aftermarket fenders and bumper. So that said, it may make sense to move forward now with the aftermarket front fenders and bumper as doing them now and not having to wrap them again later in effect pays for those parts. So I’ll just deal with the fab work and figure it out. Everyone’s input was very helpful, thank you. Now I just need to figure out where to buy the best aftermarket bumper??

And I will follow up and let everyone know if I made the right choice and how difficult it was to maybe help others. Some may say just save the $2k, and all the frustration, and they're probably right, we will soon see.

With the ACI kit I wouldn’t need the bumper as their kit can use the base C6 bumper but requires a couple other pieces for the base bumper to look right. I like the fit of the Z06 bumper so I’ll likely be ordering the JD Corvette fenders and bumpers that mirror the OEM Z06.

Thanks for info! I am thinking of keeping the base bumper what other pieces does it need?

EOS makes really good rear quarters. The fit and finish is flawless!
They also make an OE style pp front bumper. MUCH MUCH MUCH MUCH MUCH MUCH (times infinity) better than fiberglass!!!!! It's made of the same material as the factory bumper.
Check it out all good stuff.
Btw, the rear inner fender liners, aren't too hard to find, but shipping is more than the parts. The brake ducts, and inner vents are very hard to find.
***edit***
There aren't any handling issues with the rear being widebody and front base. Feels just like it did before. HOWEVER, without the rear ducts and everything you WILL hear a VERY audible whistling from the rear.

If you go with ACI, and want to use the base bumper, you would need the following which is from their website.

C6 - 2005-2013 FENDER, C-6 Z06 STYLE, RH - American Custom Industries2005-2013 FENDER, C-6 Z06 STYLE, RH

This is the latest and hottest item available from ACI for your C6 Convertible or Coupe body style! Add that aggressive look to your Stock C6 Coupe or Convertible when used with either our Custom rear Quarter Panels (Convertible), or Stock Chevrolet Rear Quarter Panels (Coupe).

And our version of the Z06 Styled Front Fender allows you to retain your stock front Bumper Fascia, reducing the conversion cost for you.

These fenders also require our wide front spoiler
(# ASF 725), our installation kit (# AFB 059), which includes everything you need to finish the job, and our new Front Fascia Flares (# AFB 051 and AFB 052).
This is what it looks like with the parts installed using your base bumper. Hope this helps.

I owe it to those who responded to my request to let you know what direction I took as far as the body kit goes. I ended up ordering from JD Corvette the Z06 rear quarter panels, ZR1 fenders, and the Z06 front bumper. I liked working with Angel at JD Corvette and felt confident they would take good care of me with my order. I also saw other success stories with JD Corvette parts on YouTube. It takes 5-6 weeks to receive the parts so we will see how it goes. I did NOT order any wheel liners, vent inserts, or any other parts other than the fenders themselves so I will be doing some fabrication and ordering off Amazon to try to make this work. Will post an update to let you all know how that goes and offer any suggestions from my learnings after this venture.

And btw, I did not compare JD Corvette to American Custom Industries (ACI). ACI may be equally as good. I just had a good conversation with Angel at JD Corvette and liked the way he followed up with me and the experiences he shared. I gained a good comfort level is all. Now let's see if they come through for me.
