Suspension Lowering Opinions

[Mikz86TA]

Looking for opinions on these options. I want the front a little lower but not too much. I prettymuch like the ride I have so far with the stock ZQ8 suspension.
If you dont know or recall, I have poly bushings on the sway bars front and rear, poly front endlinks and +1 blocks out back which leveled it out.
I am ok with the current rear height. Ok with the front 1" more lower in the front and have a slight rake.

I would say spindles but that's an inch more then you want.
Doubt you are going to find a 2.5" drop spring (would only be and inch lower then ZQ8 springs).

[Mikz86TA]

Yeah. I kinda wanted a 2" drop. Damn GM and the 1.5" drop spring :(

[87wildside]

Tall lower ball joints. Just don't tell the alignment shop about them or they may not want to touch it.

I don't think 3.5 on your truck is going to be to low. If you do it and really don't like it you can all ways get those belltech poly spring isolators (or what ever they're called, that fix chevy lean) to bring it up about an inch.

As for the back you have more options, 1/2"- 3" blocks from JTR. The 1/2 blocks bolt to there other blocks.

When I put 2" drop spindles and blocks on my Jimmy the ride quality didn't change one bit.

[Mikz86TA]

Hmm. So maybe 2" spindles and stock sprngs.

On GTO's there is a company I forget that makes zero-drop performance springs. Keeps the same height in the rear (due to GTO's having limited fender clearance with 18 or 19 inch staggered rim swaps) but gives it a better performance feel.

[Mikz86TA]

Pedders..thats the company

I was being conservative when I did the 1" blocks on the Cameo now I see its not enough, especially with those tires I have though it handles pretty well.

[rentedmule]

I didn't know what to vote for at first but Eric's idea about the tall lower BJ's is great. That'll get you an extra 0.5" of drop and improve ride quality. I'd also like another 0.5" of drop in the front - I'm not sure I could go lower than that and still clear the monster tires.

[Mikz86TA]

Rear I dont really want lower. Maybe if they made a 1.5" block..LOL. The 1" blocks I have leveled it out nicely. Just sometimes I feel it would look better with the front a little lower. And also I thought maybe a bit of a tighter spring rate would make the ride feel tighter. The ZQ8 spring up there is nice but it could honestly be a little better. There is some front 'bounce' thats a little more than I care for on some uneven rises in the pavement at highway speeds. Basically the front lifts a bit too much.
I was thinking if stock springs/drop spindles Id still get the same exact feel but better look. Then again with the 'rake' stance it would have some of the forward lean would put a bit more weight on the front and eliminate some of that front lift.
But a 1.5 spring and 2 spindle would net 3.5 drop. Maybe too much drop for my taste.
Thats why reverting back to a std height spring and the 2 spindle would be more ideal. But then Im only going a half inch lower than I am now. And Im surely to be unhappy with the spring performance. Which is where the thought of a zero-drop performance rate spring would be ideal. But no one makes a dedicated bolt-in unit for the S-series. Id have to find out the OEM spring installed height, find out the OEM spring rate and compare it to the ZQ8 rate. Then maybe go a bit tighter on the rate and get it the height I wanted. All info I dont have..LOL QA1 Im sure has a spring I need tho.
Or I was looking at the Eibach 2" springs and keep the stock spindles. But thats only a .5 drop lower than now.

Hahaha!

IIRC you have Z85 rear springs which are stiffer than std ride and ZQ8....plus a 2" block?
Up front I donr recall what you have in terms of drop products???

The bj's are another thought in the mix tho.

Whats your take on those bumpsteer correction endlinks like Spohn has? How low and what lowering products (springs or spindles or BJ's) warrant the actual need?
Id figure spindles not so much since the knuckle position isnt changed but springs Id prob guess do warrant the bumpsteer....on certain drop levels Id assume

[12sws27]

2" coils and tall lowers bj's? JTR has 1/2 blocks that bolt to their 1" blocks btw.

[rentedmule]

I have stock ZQ8 coils and sway bar with poly bushings front and Z85 leafs with 3" blocks and ZQ8 sway bar rear.

[87wildside]

Umm, you want a 1.5" block either use a flat block and a JTR shim (might end up less them 1.5") Or you could get a 2" angled block and cut a 1/2" off the bottom you anal fvcker...lol


Just so you know, I want your coils if you pull them. Those, tall LBJ and spindles will be perfect but I don't trust people selling ZQ8 springs cept for people I know.

[Mikz86TA]

Why dont u trust them?

[87wildside]

Cause 2.2 sh!t will make it so the LCA is not optimal for my application and standard Z85 springs are to stiff and to tall. People lie. I've had good luck but a coil spring is really easy to lie about. So "sale" me yours...lol

[Mikz86TA]

Ok gotcha. I think mine still have the 3 code tag on it. If you find a set of ZQ8 springs in the meantime with the tag and need to know the 3 code ID for the 6cyl versions just ask.

[rentedmule]

And also I thought maybe a bit of a tighter spring rate would make the ride feel tighter. The ZQ8 spring up there is nice but it could honestly be a little better. There is some front 'bounce' thats a little more than I care for on some uneven rises in the pavement at highway speeds. Basically the front lifts a bit too much.


HAL / QA1 adjustable shocks make a giant difference with what you're talking about. Mine did the same thing and the new shocks cured it 100%. A friend just put them on his noma and was shocked at the difference they made over the stock decarbons.

[Mikz86TA]

Hmm. I got Bilsteins stock. Do you recall the part number on those?

[rentedmule]

I think it's TC1914P
