I'll do my best to write up a respectable review once I get them installed and get a few hundred miles on the odometer.

I just ordered the Whiteline diff bushing kit. As of now, the plan is to buy a used pumpkin and swap the parts with it. Once the new gear and bushings are in i'll swap out the diffs. This way I have my stock as a spare and I can sell the upgraded one down the road.

I was also looking at using the Nismo finned cover but would rather find a decent diff cooler if I can without spending too much (looks like not). I'll be participating in the autocross events here for the first time and knowing me and my addictive personality, I'll be doing this a lot more. It's been 110-115 degrees in the shade here in Boise and I think the finned cover will be far less effective in this kind of heat. If anyone has autocrossed their G in extreme temperatures with or without any additional cooling and zero problems, maybe I'll just get the Nismo cover and call it a day.

 

Autocross runs are a couple of minutes at a time. Even in hot weather there's no need for any additional cooling at all.

 

Good to know. I guess I was just betting on the turnout to be relatively small here and the time between runs not sufficient enough to allow the fluids to cool much. I've only participated in the NHRA late night drags back home in my driving career so I never had to worry about mid-day heat.

 

I am interested in this Mod but first I want to know from folks who have purchased this Aluminum Drive-shaft have they heard any noise or felt vibration coming from this Aluminum Drive-shaft???

 

No vibrations. Slight noise from 1st to 2nd gear although its more like a hollow tube sound. Doesn't bother me since I have motordyne exhaust.

 

Now much is it?

 

Ditto what WARAT said since he has my old Z1aluminum one. For the PST CF one I have, even less noise (barely any at all) and no vibration whatsoever.

 

It's listed on their site for $600 plus ship. They're made to order so anyone buying one should expect to wait a few weeks before receiving it.

 

I get some noise and vibs from my E370 so a little extra noise won't hurt.

 

you have Vibrations with the E370? something loose or hitting the frame?

 

No problems at all. I was just referring to the relatively loud exotic note of the exhaust.

I'm scheduled to get a dyno tune next month and drag race. I know it's still over a month from now but thats the first chance I'll get to go back home where there's a reputable UpRev tuner. I'm excited to see what kind of numbers my G produces.

 

Higher gear ratios allow for less tire spin.

Overcoming tall gears wastes torque, and causes burnouts.

I remember going from 3.35 to 4.11 in my 70 Mach1, all torque, no more rear wheelspin!!
