Ive been reading that the v6 camaro springs are alot stiffer than the z28 springs? Would this help in the 1/4 mile? Or are there other cheap suspension mods?

Hey guys,


Ive been hearing some good stuff about running V6 springs in the back because there much more stiff than the stock Z28 springs. If anyone has any input good or bad throw it out.

i have read the same thing in some articles in GM High-Tech Performance. they say that they launch better out of the hole.

The 98-02 springs are supposed to be the same as the z28 springs. The 93-97 springs have a softer spring rate, if you want harder springs go to a ss or 1le spring. You should find a thread in here that has a link to the spec's on all the 4th gen springs https://ls1tech.com/forums/search.php?searchid=2235355

V6 springs are softer than V8 springs. They may help a little on the front, but not on the back. I'll actually be doing some street testing/tuning on a single turbo car tonight running V6 springs up front w/ stockers in the back. Should be interesting.

You've got it half right. They are softer, but we put 'em on the back. A stiff spring on the back will not accept weight transfer, you throw the weight back there on launch and a stiff spring throws it right back up front. A softer (V6) spring will accept the weight transfer.

I did this mod on my '94. Great bang for the buck. Did it at the same time as I did QA'1s up front and started pulling the front wheels on launch for the first time ever.

Actually, on a properly setup suspension, stiffer springs in the back will work better w/ a softer spring up front. This is why guys go w/ a 275 up front and a 150 or so in the back as opposed to a 325 and a 125. Weight transfer is one thing, but you don't want any wasted motion and planting the tires is just as important (something that may not be as good w/ a softer rear spring).

Not a suspension expert by any stretch, so you certainly won't get an argument. I tried it on my car because I'd seen other guys doing it and they were running quicker than me.

I know from watching video and the feel of my car that with the stock springs it would throw the car immediately back forward and that with the V6 springs it accepts it and the 60' is better.

So get the springs for the back and leave the stockers up front?

Rear spring rates are like everything else. It's going to vary with every car and every setup. Some cars will need a softer spring, some a stiffer. Since I don't know the answer to the next question I'll ask for you. How do you figure it out what spring rate you need?

i was going to try this also- v6 springs in the rear. then i searched and asked questions and really thought it over. i have the v6 springs and all, just after some hard thought im not sure i want a softer spring in the back.

my car already squats like a MOTHERFUKER on the rr side, i think it may bottum out so what i was thinking about doing is putting a v6 spring on the left side to get even weight transfer in the back.

the only problem with this is it is trying to fix a problem ***-backwards. putting less pressure on the lr tire that already has less weight onto it doesn't make much sense even if the car squated straighter it would still have less pressure/weight on the tire that needs it.. after thinking about this for a minute i decided to sometime (next season) get an airbag for the lr side.

from my thoughts on it i don't think v6 springs are the answer- and i agree with the one post above that the front suspension is the main suspension to be focused on first. get the car to squat straight (airbag/s) and get the front to come up more (shocks, swaybar!, battery relocation, pin-on hood, bumper support!, a/c! etc...) and you will come out harder. if you have a little leeway and can still hook with less squat adjust the airbags accordingly/adjust the shocks accordingly if you want to spend the cash for adjustable shocks.

98-02 v6 and v8 rear springs are the same. 93-97 had lower rate rear springs on v6's

for better launches out of the hole you want a softer spring, not stiffer.

sleeperstyle, your post is a little convoluted, so I'm not exactly sure what you are trying to say.

What I will say is that I have a hell of a lot more suspension mods on my '94 than '95 V6 rear springs and QA-1 12-ways up front. In other words, I've been racing my '94 since '96 and have tried/done everything in your laundry list and that the V6 springs are just one factor in my entire suspension equation. My car hooks straight (I'm not sure what "squats straight" really means) and gets great weight transfer, putting the weight on the back tires where it's needed. If it were to squat too much, I'd trim my bumpstops and/or add an airbag.

The V6 springs are softer than the z28's. I've heard some people doing this but don't know of the results.

You also posted this in Drag racing tech. See our discussion there. Lot's of back and forth. I think the bottom line is they will work well for some, but not all setups.

I run v6 springs in the rear

by squats straight- my pass-side rear is waaaay down and the driver's side rear is just down, just like the driver's side front of the car comes up alot more than the pass. side front. how ******* hard is that to understand?

idk what anybody does i was just giving my opinion.

TWS- how does your post relate to this question that was posted and i was trying to help with? he said "cheap" suspension mods- he/i didn't ask how much suspension work you did to your "94" since "96" etc...you go on to reccomend v6 springs, then in the next post say how you have tons of suspension mods done to the car and v6 springs are just another part of the equasion. im not sure i understand YOU bro...

cheap= !swaybar, !front bumper support, airbag(s), battery relocation> v6 springs

Ive tried V6 springs, stock Z28 springs, and also my Eibach prokit springs on the same setup at the same track with close to the same weather and my best 60' came with the Eibach lowering springs. Defies everything that I thought I knew about coil springs, haha.
