No problems Eddy. You will love the 55.

They are 19's. I'll be sure to post the pics when I get these wheels... should be next week. They are similar to TSW Bremma, but in gunmetal finish and you can buy them from www.euroteckmotorsports.com

Keep in mind that these wheels are very cheap (1,000$) and weigh as much as stock wheels. After spending over 25,000$ on modifications for my SLK55... I'm kinda short on cash, if not I would probably get HRE or iforged

P.S. The pic below is TSW Bremma, painted black. They fit SLK as well and are available in 18's and 19's.

Ynot,
thanks for that.
I have sent off e-mails to all the companies asking what they have for the SLK in 8.5X19 an 9.5 X19 plus prices and weights.

Cool, also check out wheelsdirectonline.com, they have Seva's for really cheap, discount ends this month, they are custom made, so it should fit the SLK. http://www.wheelsdirectonline.com/sevas/sevas.htm

Ynot,
Thanks again - I look forward to getting some replies from these companies.

Are the seva's wheels light, they look great as I assum fit and finish is up there with HRE and the other forged manufacturers.

It's the same as all the other forged brands, 24lbs for the fronts (19x8.5) and 26-27 rears (19x9.5)

jliu · 07-16-2007

are not the same. 24lbs for the fronts and 26-27 for the rear is considered on the heavy end for 19s.

the next step up is to be around 20lbs at 19.

then the next step up is to be around 17-18lbs with magnesium rims.

Then the next step up is around 14-15lbs at 19 with carbon fiber rims.

I am saying the weight, I know not all are forged the same way. From what I've seen most HRE, iForged, DCR's, DPE's, forgedline, etc, are 23-25lbs for 19x8.5 and 26-27lbs for 19x9.5s. They are advertised as light

20lbs for 19 would be considered ultralight, and closer to 30lbs for 19"s would be consider heavy.

17lbs would cost an arm and a leg

14lbs per wheel, just give them your bank account number and let them take whatever they like.

jliu · 07-17-2007

I'm sorry to disagree but the 20lbs are Renntechs and Carlssons and they are about the same price as HREs. There are quite a few others that are 20lbs and under that are priced under (list) $2500 USD a rim.

grigio · 07-17-2007

Hi,
Carlsson quote 9.6kg (21.6lbs) for the 19 inch Ultralight-not sure if this is the 8.5 X 19 or 10 X 19.
HRE Comp C21 was quoted to me by the UK supplier as 8.5 kg(19lbs) for 8.5 X 19 and 9.0kg(20lbs) for 9.5 X 19.
These are the lightest I have found up to now.
I-forge told me mid/late 20lbs.
Carlsson Ultralight and HRE Comp cost `about` the same.
These are all expensive rims.
Dread to think what Magnesium or Carbon cost.
I am still trying to sort out in my mind if I want under 10kg a rim for alot of dough or if I can live with 12-13kg for about half the price.
Just out of interest does anyone have the complete weight of wheel and tyre for say AMG III 7.5/8.5 X 18 with 225/245 18 tyres versus lightweights HRE/Carlsson/Renntech with 8.5/9.5 X 19 with the 225/255 19 tyres?
Is it realistic to expect a lightweight 19 inch combo to weigh less than the standard 18 inch AMG set up?

Its very ordinary for a 19" Forged wheel to be significantly lighter than the AMG cast 18" wheel. The Carlsson's are very classy, I would sport them.

grigio · 07-17-2007

I think/guess the 18inch AMG IIIs are around 12/13kg? without tyres.
My point was regarding unsprung weight:
Is Carlsson/HRE say with Front/rear 9/10kg+ 19inch tyres
lighter than
AMG III say with front/rear 12/13kg + 18inch tyres?
Is the weight saved by the light wheels then taken up by the larger diameter/very slightly wider tyres?

jliu · 07-17-2007

That carlsson quote was for the 10x19.

Yes you can expect them to be significantly lighter than a cast 18 stock rim. EX is the 030 rims (which are heavier than the normal rims) are over 32lbs a piece.

Larger tires will be heavier but it is not enough to offset the massive difference between UL forged rims vs cast. Also weights of same size tires are different dependant on make and brand.

ALso there is one other aspect that I would like to bring up. STRENGTH of the rim. the forged rims are significantly stronger than cast. Work in the costs of repairing bent rims or replacing a cracked rim ... I'd go forged every time.

grigio · 07-17-2007

Jliu,
Good point with the strength issue.
Just for my own peace of mind I will go through the exercise(sometime in the next few weeks)of weighing my current AMG III 18 inch set up.
By then I can hopefully find a slightly better price for HRE (or maybe Carlsson) which would allow me to change with a relatively clear conscience as far as my bank balance is concerned.

I researched this a while back...

Some links to read:
http://www.mbworld.org/forums/showth...t=wheel+weight

http://forums.mbnz.org/forums/forums...osts=12&fid=27

You'll find this data in the threads:

Okay, I weighed the stock wheels/tires. I measured them several ways and multiple times to ensure accuracy. I then subtracted the weight of the Continental tires (21 & 22lbs according to Tirerack).

Fronts = 25.6 + 21 tires = 46.6 total
Rears = 26 + 22 tires = 48 total

vs. US 030 package

Fronts = 28 + 21 tires = 49 total
Rears = 30 + 22 tires = 52 total
(according jcanabal)

Hi,
These weights show me that the only way to get a 19 inch wheel /tyre combo to weigh less than the standard 18 inch AMG III or V (not 030 package) wheel/tyre set up is to go to the expensive ultralights from Carlsson/HRE COMP.
Assuming the weights for HRE I quoted earlier and the guesstimate of 19 inch tyre weight I reckon it might be possible to shave a total of 1.5 -2.0 kg a corner.
(I read here in Germany - Sport Auto Tune up SLK55 Std to SLK55 Black- that AMG claim the 19 inch Black Series Ultralights save 1.5kg a corner over the STD 18 inchers)
Assuming unsprung weight `counts double´ this means 12-16kg `real weight´.
Not much but you do have the potential handling as well as aesthetic advantages of lightweight 19 inchers to consider.
(I have to try and justify it somehow!!!!)

jliu · 07-18-2007

Heh I was off by a few lbs. It has been so long though!

THanks for the correction.

**dsb** · 07-19-2007

No problem.

I should mention that I believe my overall weight of my 19" wheels with wider-than-stock tires weighs slightly more than the 18" stock setup. That said, I still decided to do it. I should mention that I don't feel the small increase in weight is a big detriment on the street. This is how I see it...

19" DPE wheels compared to HRE, Renntech, Carlsson
+Cost
+Look (tied with HRE)
-Weight
-Performance

Since weight and performance were the only drawbacks, I decided to keep the stocks and put some softer compounds on them. That way, I have a dedicated set for the track, etc. BTW, DPE now makes true 3-piece wheels but I'm not sure about the cost or weight.

Addicted2Speed · 07-25-2007

OK guys I just got my 19'' Sport Edition SL65-style wheels from euroteckmotorsports. They weigh around 24-25lbs
