Thanks for the STS input, guys.
Do either of you have an opinion about this question?
Do either of you have an opinion about this question?
My car is a 2011, with 29K miles on it, and the original differential gear-oil. I have two quarts of Red Line 75W90 ready to go, but intended to use them with a 4.083 gear upgrade that I've since moved to next year. (sad) Do you think I should go ahead and swap the oil this Spring anyway, in keeping with the recommended 30K interval? Or can I wait another year and another 5k miles? Or is it the time elapsed that's really the determining factor, like brake fluid? The gear oil was $33 shipped from Amazon, and I figure my mechanic would want $50, because I'm not going to DIY the fluid swap.
So should I put it off, or do it this year anyway?

Figured so. I know how it is to mod on a budget. Back in the early 90's I was heavy into the import drag racing thing and had to work on modifying my Eclipse GSX while paying my way through college all on a Tire Store Manager's salary. Thankfully I was able to supplement my income by rebuilding trannies, doing clutch installs, and other miscellaneous work for my fellow racers.
I have a possible partial solution for you... Why not wait a month until you can purchase your STS and then do the install yourself? That would save you a couple hundred dollars and also knock a month off your target install date... I understand some people are not comfortable doing their own work, so this is just a thought. Either way, car's looking great and good luck with the new mods!

The only caveat I will throw in there is that the initial couple thousand miles is the break-in period for the factory gears, so more wear is going to occur on the ring and pinion gears as well as the bearings during this time while the gears mate and bearings get seated. So the original fluid will probably have a little more "sludge" in it due to this extra initial wear. For my Jeep, after I changed the gears I changed the fluid out after the first 1K miles of break-in. I simply used cheaper fluid when doing the gear change knowing that I would be changing it after 1K miles anyway. So, if you are still concerned about waiting another year (5K miles), maybe you might want to consider just doing a quick gear oil change using a basic Valvoline gear oil for now and then use your Red Line fluid when you swap gears next year... Just a suggestion.

If I had just a nudge into the right direction, like a friend with all the above, then absolutely much of this stuff would be hands-on projects. But that just isn't the situation, so my mechanic will be doing the work.
Thanks for the diff fluid advice, though.

I don't like mine at all, they look cool, thats the only thing going well for it but its function is poor. There is no smooth output on the road as the lights seem to be reflecting all over the place. I felt the stock halogens had a smother output on the road. I don't gain anything by have these LED's in terms of light output at night that I didn't already have with the stock halogens.

Why not DIY it? You change your own oil. Same thing. Actually, easier, you'll have more room to more around with the back up on ramps, and there is no filter

I don't think it makes a big difference, and I bet most people don't change it regularly. It's not like brake fluid in that it absorbs water.

Except the dust boot on the underside. Or maybe it was just me. I cut my hand all up getting that back on. And you need to get the car pretty high so you can fit under what is essentially the center console area. But yeah, it's not bad. A little harder than changing your oil. Most of the work is done inside the car.

I'm researching right now how to drain & fill the diff gear oil.
However, I will not be installing the STS myself... for all kinds of reasons, including the same-time install of the Z1 Transmission Mount, but not to dismiss a very irrational (but real) fear of being underneath my car. Oil changes are about as brave as I can be. (Or cowardly, LOL.)
