Proven where? Read what I just wrote, Max Safe ENGINE RPM and Where Redline is set are two different things. Nissan did their homework I am sure, but if you can find any info on it, i'd be interested to read it.

 

I wouldn't do it, as you lower the psi your gas mileage drops with it too, and you'll eventually have sidewall damage. Your sidewalls simply aren't made to be driven on, and you will go through tires a lot faster if you do drive on them excessively.

If you over inflate your tires, you will wear out the center of the tire much faster than the rest of the tire. Again, going through tires at a faster rate.

I would just stick to the 30psi, you will get the best mpg and life outta your tires. If you want a better ride quality, I would suggest getting some 17's. Typically more tire = better ride quality. When i went from my OEM 17's to low pro 20's on my Z, it was like night n day. I felt every single freakin rock I ran over lol

Just my .02

 

Someone dumped water on my i-Key and now its broken

I checked on ebay and tons of people are selling OEM keys but they are not really OEM keys they have aftermarket internals. Anyone have experience with this?

 

Id go by door jam psi which is 32 for the sedans, 30psi is a bit on the lower side. Just need to check it frequently so it does not dip too low

Here is a good read on PSI and Wet Tire Performance http://www.tirerack.com/tires/tirete...e.jsp?techid=3

 

link to one of these aftermarket internal ones?

I never knew/heard of such things.

 

Best way to transport coupe seats ?

For anyone who got them shipped how much did it cost?

 

Do the coupe Brembos fit the sedan? I am pretty sure I read it somewhere that they do. And it logically makes sense that they do. Also I guess is there a difference in the ABS or brake cylinders etc that would have to be changed too?

 

Yes they fit.

I don't think you have to change master cylinder, but you do have to change brakelines IIRC.

Not 100% sure though, so you should probably wait for someone else to chime in

 

Brembos are a direct swap you need to trim you rear dust shield tho. Depending on your wheel situation you may need spacers also.

 

How do you guys hold the steering wheel? In all different situations?
-Highway?
-City Driving?

When I am driving at high speeds on the highway like 75+, I feel like I dont have enough control with 1 hand up top... How would you hold it if you were going that fast?

 

1 hand at 12 o clock is gangstalicious. I hold it at 9 oclock or partially rest my arm on my lap gripping the wheel somewhere on the bottom half. The other hand somewhere on the upper half. Taking it off only when shifting the car. (Real shift, not one of those fake manumatic up-down things)

 

left hand, approx 8 oclock

 

9 oclock in steering wheel tumb part. Right hand on shifter usually. (MT)

3 oclock for spirited 2 handed driving.

 

they fit in the backseat. you just gotta put them on a sideways "69" position and be careful when you close the door so you dont scratch your door panels with the seat rails. maybe put a towel under the rails just to be safe.

 

how much force is exactly need for this move?

This could save me a LOT of money if the coupe seats can 69 in the back seat Joking and seriously.
