Like the title says, I'd like to get some different wheels to utilize slicks on our 2012 C63 for the drag strip.

Im not expert, but doing from what I have read previously on this forum you cannot get 16s to fit with the standard brakes.

From what I remember Dads had put the C300 brakes on to fit 16s. With the standard brakes you can put 17s, Dads was running Forgeline SP3s.

I would also consider some lightweight rotors to reduce unsprung weight if you try to get the most out of the car. From what I remember you can save 8lbs per corner by changing the 2 piece performance pack rotors out, and 12lbs from the standard non-performance pack rotors.

Again I am no expert but just doing on what I have read in the past.

Wait for Dads or Dodger to chime in.

I purchased Dad's forgeline wheels and at 17" they clear the brakes fine, ran the hoosier 275/40/17, worked great. Then sold the wheels, when I sold the car. 16" won't clear stock brakes.

Forgeline make great wheels, just call them up and have 'em make you a set of 17".

I'll have to look into that.

Old clk 320 16's fit on stock calipers you just have to cut the handle off the brake pad towards the outside and use a 10mm spacer.

If I remember the specs correctly I picked up 17" TSW Nurburgring RF 17x8, 5x112 bolt pattern, 45mm offset running 275/40R17 M/T ET Street Radials. If you were closer I'd offer to sell as the wife isn't too thrilled about me using them after breaking the driveshaft on the third pass with them lol but Summit Racing has good prices (that's who I got mine from). Here's a few pics installed.

interesting... i was actually looking at maybe a 17x8 wheel for the rears strictly for drag racing... did you have to do anything special to get those wheels to fit? i thought there was no way that a wheel with offset of 45 would fit on the rears

if they fit no problem, then i can think about getting 17x8 et50 and they should fit right?

bluejae

would 17X8 ET45 5X112 bore diameter 72.6?

how important is bore diameter?

i have a drive shaft if u need.

Cant believe u broke it, ****.

Merc his prob using LC on new cars .
Dumping the trans into gear at 3500rpm ant to healty .
We did over 600passes maybe more bc every track rental we went to we did over 50 passes and we rented alot of rental never mind going to joined ones. Dodgers car.
Never had a shaft problem .

Ps save that shaft for me I might just jynx my self.

Can't believe it broke either, but fortunately they fixed it under warranty

Actually I wish I was using launch control (Race Start) because that slips the clutch off the line. I simply floored it with the traction control off which on the newer MCT cars rev up to around 3500rpm and dumps the clutch.

Need4Speed

OUCH !!!

At least they changed the drive shaft under warranty

i would not of thought they would do that ....Since you were dragging the car. i would technically think that they wouldnt warranty the drive shaft

Bringing this old thread back to life, but was wanting to confirm the size of the rim off-set before I order. Anybody run either one or perhaps both of these items?? Wheels are from post #7

I'm not sure about the wheels but I recon you get the Hoosier drag radials in 17in

skaarlaj

I bit the bullit, and ordered the items I linked above, but I'd still be interested in hearing from someone who has used them.

mr747

IF the wheels dont fit a small spacer will fix the issue

if I run 17×9 with a 35mm of set will I need spacers*
