Hi everyone,

As the title says, can this be done without rubbing? I know it depends on offset, but my rims have custom offset.

All I can do is show you few pics of how flush my rims/tires are in the rear... anyone with this combo can chime in with your experience?

It's a good look but your offset looks poor for lowering in these photos.

Shave the centres and bring them in a bit.

Do this: Make a right turn into a driveway at about a 45 degree angle and go up a little more than halfway. The LR wheel should compress and tuck in. Check for clearance.

^^ I was thinking about putting 3 adults in the back seat & stop the car on a speed bump to compress the shocks fully... to see the clearance.

sjugh, are you dropped & what size tire you have? I'm not sure if it's worth the trouble with shaving here & there just to have 0 wheel gap!!

i have 20x10 in the rears with H&R lowering springs and i have no rubbing issues. My rear offset is et 50 and im using 275/25/20 nitto invos

The problem is, OP doesn't know his offsets because the company that made his wheels consider it "proprietary info" and would not release it to him. In another thread, I was guessing 50 or 51 because it looks like my 19 x 10 et50.

Wheels/tires look pretty much flush with the fenders, I think there might be a possibility of rubbing if dropped. I'm judging this be looking at the pics you posted. You can always roll your fenders for extra clearance..

I can't believe the 007 stuff, what’s so secretive about offsets.

I have 285’s on 20x10.

My car is not lowered but it now has the necessary clearance so it can be done.

My rims initially stuck out like yours with an offset of +51 and scrubbed badly with and without passengers and lowering wasn’t possible. I had 5mm shaved off the base plates to fix the problem. There is more clearance on the inside than you may think and the inner guard is made of a soft felt material. The biggest issue is to ensure you don’t take off to much material and cause your centres to touch the brake callipers. Measure to see how much you can come in there before you do anything, I have 3mm clearance, more than enough.

efx1, do you have pics of your car? I believe the C350 can run lower offset than our C63 without rubbing.

sincity, I think you're right, my offfset looks to be around +50mm... but it looks too close for comfort even at stock height, so I'm not sure with the drop.

AMG, not much to be rolled on the stock fenders? I have rolled my Lexus fenders, but it looks so much different from our fenders. I would be too afraid to mess up my new fenders... hehehe! I don't have any rubbing right now, but I hardly have rear passengers.

sjhugh, thanks for the pics of your wheel... it looks good! Is it even safe to shave the wheels? Roughly how much to get the job done?

Here in Australia, the legal requirements for any type of modification to vehicles is as tough as nails, far stricter than the U.S., I have no idea about Canada. This is a country where it’s not even legal to use wheel spacers on road registered cars. Under or oversized sized tyres on rims are also a big no, no and if the Police see them, they will defect the vehicle and put it off the road until the correct tyres are fitted. There are also very strict limitations for changes to rim and tyre sizes over stock, you can’t just throw anything on and modify the vehicle to suit.

The rims were done by a wheel manufacturer who’s been in business for 40 years or more using a professional wheel rim lathe. A part of their business is also the repair and modification of all makes and styles of rims. The most important aspect for them was to determine the thickness of wheel bolt seats and to ensure the integrity of the rim was not compromised. Otherwise they would not do the work. They said the base plate was very over designed and that 10mm could easily be removed and still stay well within the ‘Australian Design Rules’ for rims. I only needed 5mm to be removed.

The machining only took a couple of hours to do but the measuring up of the vehicle prior to this work took a few days. The rims were checked first for the mod. A suspension shop then confirmed how much travel the suspension would have when the car squatted making sure the wheel/tyre combo wouldn’t foul any components or jam in the wheel well under full load. And a body shop checked to see what modifications could be done to the sheet metal if required. Everyone helped out at no cost, the only charge was for the machining which came to about $50 or 60 Australian Dollars.

The lip of the rim originally sat just outside the outer edge of the guard/fender, it is now inside and the edge of the tyre wall now passes by the guard lip. One of these days when I’ve got some time, I’ll have the car lowered to improve the look.

I put H&R springs on my 19" ForgeStars with 275 R11s, and they rubbed going around mildly tight corners at 5mph. Ouch. Be sure that your set-up will work before you spend the $$$ to install them.

Roswell

sjhugh, thanks a million for your input!! I kind of figure machining the rims would be the field of profesionnal & not really a diy for safety sake!

justthebest, thanks for sharing your experience. It's making me think twice now before lowering. I will experiment things on my car first before I drop it... if too much headache, it will stay as is. I will kick myself if I start rubbing left & right.
