So I assume Chevy just uses different springs to drop the z06?

how much lower is the z06 vs the regular c6? I know the c6 is at 6 inches on the frame in the front(jack point).

also is there any coilovers or anything that will give me 3-4 inches of drop?

I can't afford dropped spindles! those things are plain insane...

 

What? Corvettes since 97 have one long transverse composite/fiberglass spring for the front and one for the back. They have bolts that adjust the ride height... Corvettes are not needing drop spindles. You can put coil overs on them, but from what Ive read, they normally ride worse (although handle better). you can SLAM any Vette by modifying the sping adjuster screw bolts... just cut all the rubber off them and lower it all the way... OR you can just take the damn bolts out if you want is SUPER low (C6 only-C5 requires a longer bolt in the back).

 

You can lower a C6 the cheap (free) way by adjusting the bolts on the leafsprings. On the stock bolts you can get about 1/2 and 3/4 inch drop. If that is not enough, you can cut the bushing on the stock bolts and get about 2 inches. You can also get aftermarket lowering bolts to get the same.

I have coilovers and lowered mine about 1.5 inchs from stock. I am not sure why you would want a 3-4 inch drop. I have a hard enough time getting out of my driveway at my current height.

 

I guess you haven't looked under the car lately. Factory adjusting bolts can give you and easy 1/2 " while aftermarket bolts give like an 1 1/2" or so which will just about put the wheel lip at the top of the tire.

A 4" drop will severely restrict the roads you drive on and your handling.

This ain't no truck or Camaro ....

 

well I have a c6 cradle on a 1970 gto, lowering 3-4 inches isn't a big deal.

Its just my body is probably 9 inches off the ground, that means my frame is at 10.5. I am going to drop the cradle by about 2 inches.

which would put the body at 7 inches.

I currently have a "c6" spring with the lowering bolts and I will be at 8.5 on the frame... I would like to be at 6.5 on the frame.

The Z06 uses a different spring, I was wondering if the z06 spring has the inherent "2" inch drop built into it. Then you can lower or raise the z06 with the factory bolts.

I want to be about this low...

Helps to know that going in, don't 'cha think?

Other than the spring rate, the Z06 is pretty much the same spring as any other C6. Your best option will be coilovers.

Some pics of the front frame and suspension would help

 

Just a thought...........

If you are going to be droppng the C6 cradle that much relative to the spindles, you are going to be significantly changing the geometry of the suspensin (A-arms to frame and spindle angles) which can affect the load they can carry or withstand (braking, cornering, bump absorsion, etc).

Also, I'm willing to bet that that GTO body is heavier than a Corvette body, so you may wind up with some "unintended consequences"............even more drop at some point........

Makes me think the dropped spindles may be a safer route to go......

 

"same" geometry... same weight if not lighter. I also have a LS3 and TR6060 in the car, like the car in the pic, its a fiberglass front end.

Aluminum rebars front and rear, I maybe putting rebar shocks on the car if I need to up the weight. I am getting VERY light. Stock is 3700 lbs... the rear bumper and front bumper takes alot off there, fiberglass trunklid... front clip loses nearly a ton, doors are like tanks though. I am estimating 3500 lbs.

obviously there are some differences(105 wheelbase vs 112).

This car will be a "two seater" since the engine is pushed back about 6 inches into the cabin.

I have built everything to c6 spec(purchased the upper control arm mounts) on my wheelbase and I am getting my frame down.

I am going for coilovers but I am just trying spell out my options.

Corvette is only 1 inch wider wheel track up front.

I am kind of just doing the mock up right now, cut the firewall back and my frame is a little higher than I would like with the stock C6 spring and lowering bolts.

I am dropping another 2 inches on the cradle mounting. I guess I will just get the coilovers now and make my life easy. I just wanted to know if you could simply lower a c6 with z06 spring(leaving the bolts in approx same area).

So... If you put a z06 spring in a c6 and the bolts are in the same spot will it lower the car???

 

No, it will not lower the car. Use lowering bolts to get the maximum drop with the springs. Check with Hardbar for the bolts.

 

Z06, ZR1 and GS sit .4" closer to the ground then the base C6.

 

i measured a GS, it was 4.5, C6 was 6 at the frame jacking points

 

I do not have a definitive answer. But thinking about it, the Z06, ZR1 and GS all have higher spring rates than a base C6, so everything else being equal (including vehicle weight), they should sit higher than a base C6.

Two ways to change that is longer bolts, or a dfferent arch in the spring (when unloaded). So if you can compare that on the different springs you should have your answer.
