RennTech C63 Vs. GTR
A friend of mine just had his '10 GT-R custom tuned with the Cobb AccessPort (std. Cobb AccessPort GT-R tuning map + then custom map tuned @ a local tuning shop)...
Stock: 434AWHP...the tuner said this is the highest he's seen ANY GT-R dyno!

Tuned: 514 AWHP, 484 lb-ft AW TQ!!!!!

My friend is not b.s'ing either; this is what the dyno read and it was a Mustang Dyno. I think that's some crazy ***** right there and he's got himself a 640+HP Supercar now that should probably run in the 10's in the 1/4 mi..

The issue of the '09 transmission failure is now over, and even '09 GT-R owners can get a s/w update for the LC2.
I drove my friend's 2010 GTR extensively (in fact we switch cars once a while) all i can say is it feels like a tuned aftermarket car. The suspension ride like coilovers which gives the car a extremely stiff ride and puts a lot of pressure on the chassis. Theres a lot more i wanna comment about that car compared to GTR but i don't wanna go on and on.
However one comment my friend with GTR give me everytime he drives my car is that C63 is probably one of the best daily driver money can buy and will still race exotics in straightline and take some very high speed corners. so take it for what its worth.
The Best of Mercedes & AMG
Traditionally with everything technologically even; with conventional drivetrains and transmissions and moderate power outputs, weight has been the main enemy. With non-classical active drivetrains and dual-clutch transmissions, whilst weight is still an enemy, we see that somewhat paradoxically, velocity, or rather the need for higher velocity - as induced by RWD, street-legal tyres and manual gearboxes - becomes a greater enemy wrt the equations for KE and centrifugal force/centripetal acceleration.
All of a sudden that extra weight doesn't seem like such a problem when it's traction and DCT advantage at the start of straights has other cars accelerating, braking and cornering their tyres off just to stay in touch. It's that extra 5mph that the GTR puts on at the start of straights and the DCT that puts area (representative of distance) under the v-t graph and does the damage against cars like the ZR1. The ZR1 catches up eventually but by then it's time to brake for the next corner and even then the GTR seems better than most cars on the way into corners. So the ZR1 can out-accelerate and achieve higher peak speeds and cornering g all day long but the GTR will make it up on corner exit and entry. People will remain confused because there are no measurements for the latter and all they see is a car that laps ridiculously fast but seems to have decent, yet not spectacular, peak speeds and cornering g.
Motorsport is not about peaks, it's about averages, i.e. the average speed on straights and the average g across the full length of the corner. More importantly, it's not about speed, it's about time. Roll-racing has broke people's brains and the emphasis has moved from ETs in quarter and mile runs to trap speeds, with some vague logic about them being more indicative of a cars true potential. True potential for what? To morph into an exocet missile at the end of a straight and crash into a wall. That's useful. People should look at v-t graphs in the likes of Evo and Autocar and see for themselves just how useless achieving warp factor 8 just before you brake is at putting area under the v-t graph.

And I brought this back from the dead.

Just because it's a Nissan, come on now.
Both my brother and one of my buddies each have a '10 GT-R; my brother's is stock and he absolutely loves it (his other car is a Lotus Elise and he just ordered some new Ferrari), and my friend's is one of the fastest (slightly) modded GT-R's in the state of Florida...runs the 1/4 mi. in 10.4 sec. @ 132mph!!!
You cannot deny the shear power and "bang for your buck" of Godzilla.
They may not have the quality of an MB or BMW German driving machine, but for $80k, you can OWN just about every friggin car on the road...that's pretty good in my book!

btw -- I used to have 2 Infiniti vehicles, and I actually thought the quality was quite up to par with the German cars, and virtually no issues unlike my BMW 335i.
For what it's worth, I think the GT-R makes a great stablemate to a C63.

I disagree with you about the quality of ANY Japanese car vs a German car. For example, I used to have an LS460L 08 model fully loaded MSRP was $84,000 back then. Amazing Lexus, very stable, beautiful interior, had a lot of technology and gadgets (that are usually optional in German cars) including the ability to park by itself. Driving feeling and overall quality of the car was below the S-class or a 7 series (have never driven the A8 so can't tell) IMHO, but that's probably the reason why it was traded for an S550.
