Gears & Springs

I am going to be ordering new lowering springs and gears for my 04 gt...
95k on the car

When I order the springs should I replace the spring isolators as well?
When I order the 3:73's should I have master bearing kit as well?

Let me know what you think, the spring isolators are an extra 60 bucks and the master bearing kit is an extra 80...I would just like to know if I need either one

I have the pro kit, wish the front was a bit lower, the H&R kit is sexy. And 1LOW03GT is right, while you're in there doing the gears might as well get the extras.

A lot of guys like the front a little lower to give it a little more of an aggressive look,so either the H&R Super Sports,or the Eibach Sportlines will do it for you.
I have the Sporltines,it's a little low in my opinion for daily use as the front chin spoilers will get rashed,the the cat's on the h pipe will get scraped pretty good,and the stock k member brace too gets a good scraping.Speed bumps will not be your friend,or slanted driveways either,or anything in your way driving down the road,especial if you get caught in a construction zone!!!
Plus once you go lower then 1 1/2,you will need C&C plates,and fox body struts up front as the stock ones from the '99 to '04 will be to long and bottom out inside the strut body,and damage the strut.
The foxbody struts have a shorter shaft that will allow more travel for suspension travel.

Good advice.
Also, if you go too low and want to put bigger meat out back you may have to roll the fenders if they rub the tires.

I dropped my 04gt 1 1/2 and put 315's in the rear and fortunately they did not rub. I used Tein H-tech springs though and new KYB struts/shocks.
Isolators were fine but mine didn't have your km's so you may want to for sure.
