Like the title says, which performance parts do you wish aftermarket companies were making for our cars? I cut my teeth on 90's era Japanese twin turbos (300zx) and it seems like there isn't a huge aftermarket offering for our vehicles. Lets discuss what all is out there and where we want the product offerings to go.

From my current searches I've come across the following that are currently offered:

- ECU Remap: Piggy back and full flash
- Intake: Open filter or enclosed designs, all within the engine bay
- Exhaust: Downpipe thru catbacks, with a few companies offering smart valve openings.
- Suspension: Coilovers, lowering springs...
- Meth injection
- Turbos
- LSD
- Various transmission improvements (Weistec competition build)

Potential future parts?
- Re-routed intake (filters behind grill?)
- Larger Intercoolers
- Larger intercooler plumbing
- Sway bars
- Lightweight Drive shafts
- Upgraded poly bushings, etc
- Lightweight pulleys
- Strut bars


Let me know your thoughts! It would be nice to have a list of what is currently offered and what we wish we had.

My wish list:
- carbon fiber transmission shaft for less transmission loss
- DTM style huge spoiler
- carbon fiber parts to replace all removable original bumpers and fenders for lighter weight
- larger exhaust manifold
- AMG GTR style active rear wheel steering for much faster power lane changing and cornering for better handling
- Better LSD than current C63S equipped to help put all power down

My current mods:
- Eurocharged stage I tune
- K-Mac bushing kits for better handling
- Spoon rigid collar for tighter suspension and comfortable ride as well as better handling
- Ultraracing Front upper struct bar/lower struct bar, front lower braces, rear lower braces to strengthen suspension and for better handling
- KW suspension for better handling
- more aggressive caster for heavier steering wheel and more negative camber gain in corners, thus better handling
- 265 front and 295 rear to help put all the power down although this setup is still having traction issues

So I have driven my friend's M4 competition package and ever since then I'm trying to improve C63S handling as best as possible, M4 suspension feels so tight and its steering is so precise and responsive, while C63S got the power, it's handling is way much worse, and I want the best from both.

I'd like to see some tubular headers, I'm surprised that people who install big Yabeela and Weistec turbos are still using factory manifolds. There are larger diameter OEM twin-scroll manifolds from the E63S that could be modified (to single scroll) and bolted up.

A TCU tune even at stage 1 would be nice to have too.

We actually have a carbon fiber driveshaft from the factory - albeit, a 2-piece so I don't think there are major weight savings with it.



Current mods are:
- Dinan tune
- PS4S 305's in the rear
- ASR Exhaust Controller

Want to really want to see is an AWD W205 C63S Coupe unicorn with the 9-speed trans and transfer case from the E63S - someone with a facelift, go get it done!

TCU tune for added clutch pressure for stage 2+ cars.
A reasonably priced CAI option.
More choices in aftermarket carbon fiber body parts.
Some type of OEM approved front cooler/radiator protecting mesh.

I already checked, it isn't available for our cars.

Decent DCT that can handle 750 hp without a pressure mod.

Has anyone put the E63 turbos on the C63? Are the exhaust manifolds plug and play between the two vehicles?
