I did some research but still not 100% sure... can someone help me ?


my 2010 c63 amg pp . it has 2 piece front disc / cf trim / LSD / alcantra steering wheel


1.has stiff stock susp. is it slightly lower than reg c63s ?

2. will I rub with 12mm spacers in the rear with stock 18" wheels wrapped with 275s?

2. does it have extra 30hp ? ( I can post vin if needed)


thank you so much

Mort

1. I don't think the P30 is any lower than a regular C 63 but don't know for sure.

2. Try the spacers and see if it rubs. Since you are not lowered you might be fine.

2. (LOL). The P30 did not get the extra 30 hp but the speed limiter is raised to 174mph.

cool thank you!!

no so worried about hp anyway.. a tune would prob get more. ill do that once extended warranty is up.

dchl21

any one knows if its lower ?

dubzAMG

2010 has the p31 which doesn't have the stiffer suspension, and yes you have the extra 30 horsepower

dchl21

..... but I do have the stiffer sus.... its very stiff

Could be P30 or P31 for 2010.

Think dchl21 has the P30 or else he would have the red brake calipers.

The p30 option (on early my2010) does have a lower and stiffer performance suspension. It's the best c63 you can own as the extra hp of the p31 is easy, cheap and reversible for servicing if necessary. After driving a p30, other c63 feel a bit floaty and loose...

dchl21

yes ive p30 ...


thanks a lot guys .. I guess I got it all except the hp.

U will rub with 12mm & 275/30/18.. Cuz ur oem wheels will be 18x9 +44, and 275/30 is very aggressive.

But as Mort said, u got nothing to lose than to try it since u r at stock height, it won't rub unless u have passengers or go over bumps at high speed.

dubzAMG

according to your link, 2010's have p31, which doesn't have the stiffer suspension like the p30??

dchl21

ya ... p31 = red caliper / +30hp

p30 = LSD / stiffer sus

avery.whss

easiest way to tell is if your intake manifold is a dark grey its a P31...if its a white/grey then its a P30...I'd rather a P30...you can get the extra HP from a simple tune...LSD and the suspension helps alot

Mort

Typo, the OEM rear wheels are 18x9 +54

A lot of guys run 10mm spacers on the rear with OEM wheels so trying the 12 mm and seeing how you make out shouldn't be too big a deal.

Yes, the darker grey intake manifold should be proof positive of a P31 engine build.

Roswell

Oups, not a typo just a miscalculation lol

18x9 +54 - +12mm spacers = +42mm offset, not +44mm.

I'm running 10 mm spacers right now (+44mm) on my oem wheels, and I'm on 255/30 & it's tight fit.

My guess is 12mm (2mm further out) & 275/35/18 (20mm wider tires) will not clear the fenders. But stock height & stiffer suspension might minimize rubbing, but I still think it will rub.

It states starting with December production so P30 was offered early on in 2010 model year which would be what the OP has.
