How much better will the M6GC CP be

[JOHNBMWM5]

To drive than the LCI M5 I am part exchanging for one?.
My M6 GC CP has been put back till October delivery because the factory is closing for summer holidays for 4 weeks

I did briefly drive the M6 GC months ago and can't remember how it would compare, anyone?.

[jeroguz]

tighter steering, 20% stiffer suspension on sport plus. I really felt the difference when I drove them back to back.
15 more HP. Supposedly brings it sub 4 in a good launch control. Suspension 1 inch lower and makes it look slick!
I have it and I love it.
I wish i had twister roads here in south Fl

+1 All correct except the suspension isn't really 1 inch lower, and non-CP M6s have hit sub 4s as well (3.7s according to some publications). The steering improvements alone are worth it.

Thanks for your input guys.

It's worth the upgrade. I love the CP!

I didn't get that! are you comparing M6 GC CP with LCI M5 or CP with non CP ??
Also as far as CP it's 10mm ( not 1 inch) lower than non CP as far as I know...

CP M5 is 10mm lower than non CP M5
no difference between CP M6 and non CP M6

Interesting. This FAQ post came after and it has almost the same information but doesn't mention M6 in the lowered suspension part:

http://f10.m5post.com/forums/showthread.php?t=861925

"• Stiffer and lower suspension (shocks and springs) (10mm lower than standard M5)."

also,

"How is the suspension improved exactly?

The following is my own summary: 10mm lower suspension (M5), stiffer front bushings, revised springs/shocks and stiffer sway bars."

Anyone else wants to solve the mystery?

From BMW official website,

BMW M5 Sedan Competition Package:

"A modified exhaust unit provides an especially sporty engine sound − with goosebumps guaranteed. On the racing circuit and in everyday use, the specially designed suspension, which has been lowered by 10 millimetres, and the extremely sporty direct steering ensure that every command is executed with maximum precision.

M6 Gran Coupe and M6 Convertible have the same text. All M6s don't mention about 10mm lowered suspension.

My M5 is none CP.

[lfc3153]

It says in the German price list that the M6 is lowered 10mm.

I did a PhotoShop comparison of Palnuts two M6's, one CP and one non CP, the ride height was identical.

Non CP

Thanks for the comparison. It looks fantastic!

It's weird that when I browse related web pages, some media say the lowered 10mm suspension only applies to M5 and M6s are not affected, while some say it does to both.

[lfc3153]

I repeat, in the German M6 price list it states that the car is 10mm lower. Mind you 10mm is not a lot and the + or - tolerance probably covers this. On the other hand UK and US versions of the Comp Pack may differ to the German one. Anyone care to look up their price list? I don't have a UK or US one. Cheers Brian

It seems like the US price list doesn't say 10mm lower suspension in the CP part.

I feel they are not identical! I mean the first and second pics show different at right side of tire! anyways I measured the fenders to ground the other day. All fenders to ground measured 27 3/4 inches. My car is stock M6 Coupe non CP. Any body has stock M6 coupe CP to measure and confirm?

Maybe on the GC it made a huge difference by on coupe it was very marginal and the key standout item was the exhaust - it sounded better.
