A 4L80E would be a wiser choice than keeping the TH400.

You will regret dumbing down the rear gearing. If I could do it over I'd have put 4.56s in the back of my wagon with the OD trans. That's the long term goal anyway.

Put a 275/60R15 on the back.

5664s up front and 5413s out back for a sporty ride.

Welcome and nice wagon. Just my opinion but Ireally like the stance you have now. You do you!!!

Agreed on the gearing.

There's others out there but I like this one because of the vast number of trans it auto populates the ratios for.

Often times people *think* they should want a gear based on what talking heads say, but, in reality when they account for tire sizes and the power band for their specific build they would've been better off with something different to move the usable zone of their power band...

If I would have built it that’s the route I would have gone. Do you happen to know how much tunnel massaging is needed to fit the 4l80

Thanks. Only issue is that the bumper scrapes and the ride is to fluffy for me and I want a wider tire in the rear.

No tunnel modifications are needed for a 4L80 in a G body

Have you run that tire before are there any things one needs to change to run it.

Would say the stock wagon coils should give plenty of “lift”

Will the springs that were suggested change the ride height and if so which way.

without knowing how old(or what)your current springs are,a new set of springs and shocks will do wonders.spend as much as you're comfortable with on the shocks,they're the brains of the whole operation.even cheap replacement shocks will change your current situation but depending on what your goal is will decide on shock selection.
