I want to do one of these options this june but I don't know which one to do first. I want to know what most people would do first. I like how the lsd gives better traction and launches but I also love how Benzworks long tube headers will give me 30hp and torque while making the exhaust note a lot louder. I already have a tune on my car by ETG and row air boxes/filters so if I did the headers I would probably have to get it retuned again.

 

prolly LT headers first...

 

I personally went with upgrading my lsd first. IMHO, the car does not need more power, it's nice to have. I upgraded my lsd, then went with a tune, then followed up with my arh/mhp LT headers.

Some people will tell you that if you don't track the car, you don't need to upgrade to a lsd, but I noticed the difference. The car has better traction and the traction control isn't triggered as often.

 

Is the launch a lot better too? Are you able to notice a significant difference in your 0 to 60 time with it?

 

get the LSD, i have it compared to OEM and the car picks up pretty good, never tire spins even if i WOT it off a light, it just hooks up and goes

LTH is loud..really loud

Heres a video (not my car)


but it sounds like a lion running down the street looking for heads to eat, you might **** alot of people off

 

Do the diff first. Headers are going to just exacerbate the issue in the rear end even more.

LSD changes these cars entirely. You won't be disappointed.

 

The C63 has grip issues at the best of times. LSD is a must have.

Do you have somewhere you will use the extra power everday?

 

LSD --> Tune --> LTH /thread

 

Seconded.

Although I went: Tune (Eurocharged V5) --> Wavetrac (On Order) --> LTH (Still Shopping).

 

I did drop and tune first followed by exhaust work. But Im looking to get a LSD next... theres so many out there wavetrac, quaife, kleemann, renntech...is wavetrac the preferred brand?

 

The Wavetrac unit is great. Installation is pretty straightforward and the overall value is tremendous.

From what I've read, there are many out there that prefer the Wavetrac unit to the optional OEM LSD.

 

wavetrac has advantage when one wheel is off the ground...
technical details are on their website...

os giken provides diff to renntech...
