New calipers...
So these just came in on the UPS truck... They are 4 piston brembo calipers from a 2002 S-Class...I know i need to cut the dust shield but would i need to shave the steering knuckle...can i use c32 rotors or r129?

345MM Calipers?
You may use C32/C55/CL500/C230 Sports.... the list goes on but I would use the C32 rotors and cyro treat them!
You might need to trim the steering knuckle but I would try to find an alternative and try to route the brake line differently with adapters and etc so you can avoid that.
Congrats on the new brakes too! It's gonna feel gooooooooooooood on the 300E.

I think these are 330mm calipers... they have 7250.02 stamped on them..I'm not really sure on the part number....you have a v8 and these are supposed to be bolt on but do i need the change to a late LCA?
or they may be 345mm from the s55 but im not sure?

Unless you track
the car cryo treating the rotors is going to be about the same expense as getting a new set the next time you replace the pads.
Great process if you race the car as they freeze with liquid nitrogen the rotor down to -300 f for a few days and it changes the crystalline structure of the metal to make it even tougher then heat treatment.There are places you can send new rotors out to for treatment but it costs a few hundred dollars for two rotors after all is done.
good luck with the brake change,how are you going to proportion the brake balance front and rear?install a proportioning valve?

I used these calipers with the c230 sport rotors. I had to use a spacer on the caliper. I think that with the 129 rotors this would not be necessary. I do not know about the others. I like the set up I have because the brake are offset the same as the factory.
The brake lines are pretty easy. I got custom stainless braided ones from Paragon Performace. Confirm the fittings on the ends. I ended up getting the wrong ones on the inboard but made them work. The length they have for this application should be good. He kept the info for this conversion.
I used a banjo fitting on the caliper for the clearence issue.
Besides the stainless lines really firm up the pedal.

Well, after doing some research these are w220 w215 calipers from the 00-02 S-Class CL500. I would need to get 330x32mm rotors and apparently the 02 slk32 also has the same size rotors. I don't think it came with the same calipers. I need to know how much of a bolt on a 300e these are. What parts would i need?
You need 17" and up to put these on with enough clearance for the caliper on the spoke.

Get a two piece rotor if you can. Those big 'uns are about 10lbs heavier than the 278 and 300 mm rotors. I thought about doing this upgrade on my coupe and it seems that the added weight of the rotor really cancels out the weight lost going from the cast iron 300E calipers.
With these brakes you'll def want to pick up a set of SL500 rear calipers and rotors (the 300mm ones) to maintain some semblance of brake balance unless you put a valve in line like ohlord suggested. Some of the SL500s up to '02 had 334mm rotors, and the caliper looks exactly like that. You probably will need the newer LCA. If you aren't running the biggest stickiest rubber you can find I would recommend that also :p Put some SS brake lines on there while your at it. This mod is really more for looks than anything. You can get pretty much the same stopping power out of a 2 or 4 piston ATE with R4S pads and a good rotor. But it does look bad *** when its done.
Good luck!!!

Thanks Quicksilver. It's just a daily drive and it's more for looks. I guess i'll just get the ATE 4 piston calipers and some cross drilled rotors.
So, chris still have those ATE 4 piston calipers?

My calipers are from the CL500 as well and they are exactly the same as the C32/C55 but the brake line part was different.
The ones you have I am REALLY confident you will NOT need to trim the steering knuckle. You'll need to purchase some L-Shaped adapters for the brake lines. Can you take pictures of the caliper where the brake line connects to? If I can - I am trying to get my car worked on this weekend and if it's on a lift I'll take a picture of what I'm talking about. Anyways, C32 rotors will work or even those SLK32 rotors you're talking about.
17" Wheels of course
and also - You can invest in 2-Piece rotors like Mike suggested but keep in mind how costly those are.

I have a grinder and can make space and could get some stainless steel lines from russel performance. The only thing i don't want to do is to change the lower control arms. You have a e420 and i guess the lower control arms are different. If you can take pics for reference that would be great.
