BUILD THREAD 86 GP 2+2~Blown 6.0

I've also decided, it needs more low.

Once it gets the oil pan swapped i might cut 1 1/2" off the springs. Its got factory length 5660's and .5" longer lower ball joints in it, so the fact it's as low as it is is pretty good.

Drop spindles! Or, get a pair of 5662s to cut. I think it'll be too soft once the 5660s settle.

I'd do 2" drop spindles and stock 5664s - my wagon rides like a dream, so did my Buick (it's 5664s were chopped a coil with B-body spindles).

So I have a hollow 34mm front 3rd gen sway bar and the 1" blazer frame mount rear bar.

Are 5664's over sprung with that heavier bar? I know the concept is heavy bar/soft spring or soft bar/heavy spring. Is heavy bar/heavy spring OK to go with?

Drop spindles aren't out of the cards, but since I have modified stock spindles right now to fit the LS1 brakes I'd have to modify another pair which I can do but I'd rather not. My 5660's have already been on 1 year so I think all the settling they might have had in them has happened.

Heavy bar heavy spring is fine. SSLance does it on his Monte named Barney and he does SOLO racing....

I dont think he is as stiff in the front as you think. BBSS

He has no bar in the back with 600 lb rear springs on his coil overs, no drive coming off. I told him take a big swing with a stock ish rate bar and cut the spring rate in half

So I talked to a guy at a autocross that has a LS monte with everything that DSE makes on the car.
I think this?

He used to have a swaybar on the back and it just picked up the rear axle on turns. Not sure if thats too stiff in the rear or front (I guess that means the front is loose and the back is tight?)

The purple sticker and lots of buyer's remorse.

Your car needs what your car needs. Plus sized tire/wheel package, supercharged iron block LS, etc will need something different than some random guy with a purple car.

5664s and a 36mm sway bar is a factory combo in a 3rd Gen F-body. It hardly qualifies as big bar/big bar.

Putting 800lb/in springs and a solid 1.75" swaybar up front is a better start.

Cool. I didn't know the 5664 was a factory spring. My car is without a doubt heavy with the blower, coolers, and eventually ac compressor.

I'll get ac on and maybe look into some heavier springs with a coil cut.
