G550 vs. G63 fender flare width

My G has the narrow fender flares but I'd like to replace them with the late model (or G55/G63) wider flares. In addition to lifting my G, I am putting spacers on my wheels. I'm going to end up with 275 70 R18 or 285 70 R18 tires...I'd like to know if I should buy 30mm or 50mm spacers. Ideally I'd like the tires to line up as close to the tops of the flares as possible. Thanks.

are you keeping OEM rims ? if you're doing the flares even 285's with 31mm spacers will do little to fill our the flare....50mm would push that to the edge almost. What's your goal - handling or just looks ? if you're open to new rims you could get the right offset dialed in and fit up to a 325 in there...... tthat as a set of softer shocks transforms the handling and ride IMHO....

I'm sticking with the stock wheels. If I were to switch, I'd probably go for a set of used G55 AMG rims and have them refinished.



That's from the JWO website. Those are stock G class wheels with the 30mm spacers. That said I don't know if they are 7.5" or wider. I was hoping that, based on the above picture, the wider flares would cover the wheels perfectly.

I'm going to go to the dealership next week. They have a G63 and I'll see if I can measure the size.

I didnt know there was a fender flare difference between the 550 and the 63. Good to know then.

with the 63, I went with 31mm wheel spacers and its perfectly flush to the top center of the flares (stock wheel and tire size)

Through a little googling...it seems (though there are a few conflicting sources) that the G550 is 71" wide while the G63 is 73" wide. Visually this seems roughly accurate - that each G63 flare is approximately 1" wider than the stock one.

Yup - 22mm supposedly.

The OEM G55 rims are 9.5 wide vs. the narrower typical 550 and 500 rims, so IF you went wider on tire then 285 they would work better...

Jack at JWO just confirmed 30mm spacers on 7.5" rims with 285 tires will nicely fill out AMG fenders.

Finally getting this build sorted!!!

Hey JD101b, I am in a similar situation. Looking for AMG Fenders to replace the factory set on my wife's 550. Where did you source your fenders from?

Thanks,
Chris

Jack @ jackwagon has a matte black set of the 55/63 spec flares that work well unpainted, or could be painted ...... easy swap and great price.

pic of them as they came out of the box with 10k on them..

My bodyshop guy is booked solid until late March so I decided to paint the fenders myself.

It has been a bit of a learning curve. This is the first time I've painted a part on the car that requires a really good looking paint job (I've refinished the oxidized underside of the front skid plate and both running boards before). I managed to smudge the paint, ever so slightly, on one of the fenders even though I let it dry overnight. My garage is around 55 degrees and under 30% humidity but I guess that still wasn't low enough to adequately dry. I'm not sure if I should sand the entire fender or simply clean it and give it another coat. Any thoughts?

I'm using the tried and true Rust-o-leum method - a few coats of primer, a few coats of automotive gloss black enamel and then a few coats of automotive gloss clear (the automotive products are formulated to provide greater UV protection). I'd really like to use Eastwood 2k clearcoat but the rust-o-leum fumes are already making their way into the house, and 2k is way, way more toxic. Hopefully the gloss clear will help it to pop a bit more. I'll probably end up brining the fenders to my detailer and see if he can polish them before I perform the install.
