R35 Gt-r Too Noisy? Too Much Nvh? Fix It!

[GT-Ricer]

I've decided to re-trim the rear child seats in good quality leather to replace the horrid vinyl / pleather, which detracts from the rest of the interior.

Just another cost cutting measure by Nissan not meant to be noticed by us, the crazy "speed freaks" who never look over their shoulder.

( Yes, I really do love my car so don't all jump in telling me the usual things, how fast and "affordable" it is etc)

When I removed the rear seats it became painfully apparent to me how much mechanical noise comes from the transaxle, suspension and rear tyres road noise.

Most of it is remarkably well muffled by those flimsy rear seats, but not all.

Also, the heat which the transmission generates goes straight to the console and the rear seats- just touch them when the transmission oil reaches 90deg!

You can boil a soft drink in the rear cup holder after one hour in the car.

Solution: line the rear seat compartment with heat shield fabric and 3 layers of recycled cotton Removalist Blanket sandwitched and stuck with double sided tape from Bunnings. Total cost $50 + 4 hours.

The job takes a bit of effort, but it's worth it. My car has been transformed to a much higher level of interior ambience, which added just 2kg to it's weight and $100K to the way it

sounds and "feels" inside.

If the clunking noises of the gear box, the thumping of the rear suspension over the pot holes and the roar of the rear tyres add to your overall enjoyment of the GT-R, this mod is not for you,

because they are all gone now and I can enjoy the sound of the engine and the BOSE sound system uninterrupted. I love it!

I might have a little project for the weekend...if I can show my wife that it is quieter...then the Willal mid pipe may be an option.....hmmmm

Leather seats now installed.

Looks the goods, well done.

Excellent modification GT-Ricer, Im really impressed with that and from what you say makes a big difference. Did you install any of the sound deadener yourself? or was it done by the motor trimmer who did the leather seats?

Also correct me if I'm wrong, but you have an E55 AMG? If so, how does this compare to the GT-R when you stick the boot into it??

Thank you. I did all the sound and heat proofing myself. There is nothing to it, just patience.

My rear seats look even better now than these photos. The trimmer has now heat shrunk the leather so there is no more sagging and it looks totaly original.

As to my other car, the E55, it is very fast for a 4-door sedan but not as fast as the GT-R. To start with, it is pretty hard to get traction with RWD and 700Nm so the ESP robs you of all this torque on launch. 5 gears are much taller, especially the first two. My best 400m was 12.35 sec in the E55 and best 0-100 4.5 sec but generally I would do 12.6 and 4.7sec. The GTR alraedy did 3.9 and as it loosens up, it will hopefully do 0-100 in 3.6-3.7 sec and 400m in 11.8. Around EC the E55 will do 1.53, Wakefield 1.09. I hope to do considerably better in the GT-R. In all gears the GT-R just feels ballistic and is never overwhelmed by the engine. The E55 is a great sedan, but if you mash the accelerator and try to use all its power and torque at once, it just disappears in a cloud of smoke.

mind you, if you know how to use it, it still totally destroys all FPV's and HSV's around OP , Wakefield and EC as well as a few Porsches, M3's and Audis RS4's, but it would never match the GT-R on the streets or the track. The GT-R will never match the E55's refinement and quality though.

Different cars entirely.

Thanks for your feedback GT-Ricer. The GT-R and E55 AMG are definately my two favorite cars, if I recall you had the CL 65 AMG rims too- magnificent! I guess they don't come cheaply?

Anyhoo, I was most interested in the seat of the pants feel of both vehicles, the more I read owners views about the GT-R the more I believe it is the world's best sports car. The E55 sounds like the best of its breed too. I was abit disappointed when Merc went to the n/a 6.3. It's great but the 720Nm/1800 rpm, plus the 5.5 S/C noise is too good.

Very nicely done on rear seats. Looks OEM. Should have been OEM.

[URHYNS]

looks great

[LSX-438]

damn, i dont even have the rear seats in!

[handbrake]

haha, yes, best solution for poor rear seat quality - remove them.
