Hi fellas,
I just bought a set of HRE M49 wheels/tires originally sized for a C63. Talked to the original retailer and HRE guy who verified I'd need spacers.

OK, my questions are 1) what size spacers would people recommend and 2) what size extended lugs would I need?

Here are the specs on the HRE's:

Front: 20x9 offset 39
Rear: 20x10 offset 53
(just about standard offsets for stock C63)

I'm guessing I could run the fronts without spacers but would need ~10mm spacer in rear? If so, what size extended lugs should I buy?

Thanks guys!!!

get H&R spacers -- front: 10 mm spacers w/ 14 mm x 1.50 bolts (40 mm length) and rear: 15 mm spacers w/ 14 mm x 1.50 bolts (45 mm length).

this will give u a nice stance, nearly flush w/ fender.

make sure u run 245/30/20 (front) and 285/25/20 (rear) tires so u don't rub.

of course, post pics ASAP.

Man, i kringe at spacers, especially that big. send them back to HRE to have the barrels fixed.

+1, the beauty of buying HRE wheels! Also don't forget that Porsche used 1"+ spacers on the rear of ALL their Turbos up to 1989, so running thick spacers with high HP is OK, but if you can have HRE change the offset so it is more -ve (which they can) then I would go that route.

jangy, ideally u don't want to use spacers but if u get a great price on a set of wheels then spacers r ok, as long as they r hubcentric.

i am running H&R 10 mm spacers for both front and rear with my HRE (pictured in my sig) and u can't even feel ur running them.

my offsets: front 28 mm and rear 37 mm. no rubbing w/ 245/30/20 front and 285/25/20 rear tires.

when i contacted HRE to see if they can change the offsets, they said they can only do 2 of the wheels, so my only option to make them fit was to run spacers. i'm very happy w/ the fit and feel of my wheels. no issues and they look killer

Agreed, your car looks incredible..very yummy!

Thanks guys for the suggestions!

Just as jtc55 mentioned, I got a very good deal on these HRE's and don't mind running modest size spacers. If I could fit the fronts without spacers I would.

Can you guys clarify about HRE changing the offsets? Didn't know this was possible. Can anyone provide more info?

jtc55

don't know if ur front wheels will fit w/o spacers, mine didn't. even if it did, i would have run the spacers anyway b/c i want an aggressive offset for that "flush" look.

regarding changing ur offset, call HRE directly and give them the 2 "serial" numbers on the back of the wheels. they will tell u if it's doable or not. good luck and get the wheels on already.

You are taking a leap. To further prove your point, companies sell spacers and people use them so they must be ok.

I hate spacers because it is a compromise that does not need to be taken. The safety issue is actually only a small part of my hatred for them. I hate how they "feel". I spend thousands trying to reduce unsprung weight only to add anchors to them?

jangy

Those are good offsets for the tire sizes and i never doubted that spacers could help get the proper offset on a wheel that otherwise is not going to work.

jangy

The wheels are three pieces. Two make up the actual width and the third is the face. The size of the two barrels is what gives it an offset. For example, on a ten inch rim, a 3" and a 7" gets you an offset of about 40.

+1 Those who roll dubs are not going to be bothered by spacers jangster.

jangy

I thought of that after I was responding. I saw a few E55s today with 20s and they do look sweet.

Stupid question guys...

Are typical HRE lugs usually "ball seat" or "tapered?" Need to know this when ordering the extended lugs but my seller couldn't recall right away. Figured I'd ask the veterans!

jangy

Ball

zefpashko

I thought that HRE's typically used tapered or cone type lugs? Double-checking with the original retailer before I order them. The seller didn't know off-hand either.

Vader55

Why not just call HRE ?

They are whatever our OEMs are NOT. I thought that I remembered the OEM ones being coned and the HRE's being more rounded, so I assume that means ball. I remember something about acorns?

OK guys,
Finally got the H&R spacers and extended lugs and now I'm having some other issues:

1. The 10mm spacer for the front doesn't sit flush on the hub. I got the correct 20556659 with the extended hub center but it's still a tight fit. Sitting about 1cm off the hub. Don't want to hammer it in for fear of not being able to get it off!

2. The extended lugs I got for the front, 40mm length, are too short. If I mount the wheel without the spacer, the extended lugs are just about long enough. With the spacer they'd be too short. If I try the OEM length lugs with the new wheel without spacer, they don't thread at all. Way too short.

FYI, my HRE M49 wheels use the ball-seat type lugs.

As you can tell, this is starting to really aggravate me! Much bigger headache to fit these incorrect offset wheels than I thought it would be. Just trying to salvage this project without a lot more headache. Any help is much appreciated!

I am having the same problem did you get this sorted?

the centre spigot bore on the front hub of the car sticks out by 25mm and I am trying to fit 15mm hub centric spacers so the wheels will clear the calipers. But they do not go on because the step inside the spacer is not allowing the spacer to go on. I think I will go with non hub centric spacers as that will still leave 10mm to line up the wheel, has anyone else had to do this?
