While swapping out my 1LE wheels for winter shoes I tossed them on the scale, not exactly scientific as I have no idea the tire weights. Bridgestone A/S on MMR replica Z28 rims vs OEM forged 1LE with 4S's.

You can get the tire weights of specific tires off websites like Tire Rack when you pull up a specific tire and size. It would be interesting to see the weight difference between the MRR replica 1LE wheels and the oem 1LE wheels. My guess is that the oem 1LE wheels are lighter since they are forged.

Tire weights vary too for the same size tire depending on the brand and type of tire so you would need to look at those weights for the total difference. For example a winter tire might be heavier than a summer tire.

I got 6th Gen center caps for my MRR017 1LE wheels. They fit just fine.

I shoulda have said the MRR 228 uses the 5th gen caps

Oh... Gotcha... Ya that could very well be.

I can confirm, they are a smaller diameter.

So are the lug nut cutouts on MRR wheels, that's why one can't use stock lugnuts (or McGards) but need special, narrower ones for them. I'm not a fan of that design decision.

I am just about to pull the trigger on M017's, 20x10 in front and 20x11 in the rear. Planning to do tire sizes 275/35/20 on the front and 315/30/20 on the rear. I have seen a couple of different answers about front spacers I like to verify, I don't really want to run spacers. I have seen a couple threads say they are needed with MRR wheels, and a couple threads where there was no mention of needing them. In talking with MRR, they don't mention needing them with that set up. All the specs I read make it look like the fronts 285/30/20 stock 1LE size tire is about 1/2 inch wider than the 275/35/20, so I can't understand why the additional +3 offset would create a problem with the MRR wheels. And doing my math, it would appear the rears should be fine without Spacers. I'm not even sure the 315/30/20 in the rear requires the wiring harness relocation.
Any feedback would be appreciated.

I went with the below. This is the stock OEM ILE wheels sizes. No spacers and no need to move the wire harness in the rear wheel well.

MRR M017 20x10 +23mm
MRR M017 20x11 +43mm
Continental 285/30ZR20
Continental 305/30ZR20

If you go to your tire sizes then I do believe you need to move the wire harness for sure. Not positive on the spacers. I have not read or seen anyone say anything about spacers.

You should be fine, I just went with MRR017's on my 2SS, I currently have 285/30 & 305/30's but when tire time comes I'm planning to go 275/35 & 315/30 like you are.

You don't need spacers and as long as you don't run 35's on the rears the wire harness should be fine (I did move mine just to be safe since I was already in there).

+1 on the "no issues, no spacers" with the 275/35/20 in front and 305/30/20 in back on the MRR017's

Thank you!

I wouldn't hesitate for a minute to move forward with your current plan, you'll love them...
