Suspension setup

[custom442]

Here's what I'll be setting up on my car, after a long time thinking about it.

Front:

Moog 5662 front coils, will be cut for 1" - 1.5" drop (I need one above 700 lb/in spring rate)

any fully adjustable front shock, set at hard

Front anti roll bar, found one on summit at 1 3/8"

positive caster, negative camber, toe out (just a little)

Rear:

Moog 6377, will be cut for the same 1"-1.5" drop (need one above 140 lb/in)

fully adjustable shock, set half

stock rear sway bar for now (I don't want to go bigger than 1" unless I have a hard time putting power to the ground, in which case I'll need to make my own front sway bar to compensate cuz they don't make one bigger than 1.5")

Wheels/tires-
16x8 gotti 3 piece aluminum rims
some sort of summer performance 255/50/16 tire (will need to find appropriate backspacing, could be a headache to fit on the front... but I will make it work)

new jounce bumpers

already have a GM fast ratio 12:1 steering box

stiffen it all up with as many braces I can get, and new bushings on everything I can think of

take a little air out of the front tires and a little more outta the back and it should be handling much better than a FWD ricer

both those springs have one tangential end so they can be cut a good ways without hurting performance, just make sure you don't want a smooth ride before installing

Where did you get the Gotti rims? I'm looking for them and see you can order them new online from Europe.

yep, that's them. Those wheels are great. A company called Simmons makes a similar rim to the one we are looking at by Gotti, a lot of GN owners get them. Also very expensive though.

weights for some Gotti J55A:

8J x16" ..... about 8.500 kg / piece = 18.75 lbs each
^^^ this is the one I'll be getting, with the center painted black, these are 465$ per wheel plus major shipping costs

10J x 16" ..... about 9.500 kg / piece = 21 lbs each
500$ per wheel

I just like the gotti ones better, but that's because I want to go with the FE3x theme

I heard gotti makes their wheels under a different name for older bmw's, porsche's, and european sports cars

the french only make directional rims...they all go backwards .... :lol:


if you using your car on the street that suspension set up will be extremely stiff.....for the front I'm running 660 lbs with Afco shocks -#7 valve which is the stiffest they have in that shock and it's pretty stiff but I like it......the moog spring has a 706 spring rate and when you cut the spring that will increase the spring rate. Also the front sway bar will significantly add to the spring rate of the springs...

Like I said, I thought about it for a long time 😀

for the back the springs you listed are double pig tails so if you cut the spring you'll need to change the spring pocket. You might not need to cut them tho. You need to find out what the rear weight of a Monza since the ride height with those springs in that vehicle is 10.25 which is the original spring height load height for a G body. The Monza spring is also almost 2" shorter at it's free height compared to the G body spring with a comparable spring rate. I'd suggest you try the spring before you cut it and see how it's sitting after a few days to let it settle.

:evil: I thought the 6377 had a tangential end. The spring rate is 141 lb/in on this one which is about 20-30% above my stock springs. But you're right I'll need to find another one that I can cut easier. Thanks for pointing that out

No, wtf lol... the 6377 does have a tangential end. Maybe you were lookin at the 5377
