I have a gs430, I wanted to know if the is a way to lower the RPMs at cruising speed. Is there a way to make the 5th gear longer? Right now I can cruise at 75 at like 2500 rpms or so. Is it possible to get that down to lower that? I want to gain some MPG's on highway cruises. Will this affect my other gears and how they shift?

 

the gs3 cruise 75 at over 3k. i would like to know too

 

u can switch over to the gs430 set up, but you will lose acceleration.

 

My older G35 sedan was the same way, and it guzzled the gas. The 6 speed technology helps. Unless you plan on some solid mods to the transmission I would say there is not a lot you can do other than slow down to save gas

 

ok sounds good

 

Hmmm would have to say you would have to switch out the rear end , dunno which one though

 

bigger wheels/tires.

 

if i switched out the rear end, wouldn't this affect all the gear ratios? i am really only looking for a longer 5th

YIKES!
