Default Lowering the C3

So I stopped off at Midas after work today (took the Vette to work since it was quite hot today). I booked a wheel alignment and asked if they could lower the vette while it's in the shop?

I tell the guy to cut a 1/2 to 1 coil off the springs and he says that's not the proper way to do it. You need to get "drop spindles." He said that by cutting the spring it'll throw the geometry out and things will start wearing faster than normal.

On CTOF, that's all I hear about is people cutting springs. What the Midas guy was saying seems to makes sense. Have any of you cut your springs and then wish you hadn't, or have some of you used drop spindles before? Have you cut your springs and all is still right with the world? Which way do you think is better?

Do you really want this in OT?

Cut the springs or get shorter springs. Drop spindles will f-up the geometry. The scrub radius will change dramaticallty.

But when you cut springs, they get stiffer, too. Just be aware of that. Personally, I cut 1 full coil off mine and got a frop of about 1.5-2"

Would you also recommend cutting a new set of springs? I'd be concerned that with old springs the drop wouldn't be the same on both sides...

If the springs are sagging to the point where you think they're uneven, you'd be better off getting new springs that are already lowered. That way you have some control over the spring rate.

It's a complete knuckle except the spindle part where the wheel bearings ride is raised relative to the rest of the knuckle by an inch or two or whatever. So the suspension sits at the normal height, but the wheel is shifted up higher. So the "spindle" provides the lowering and not the spring.

That's a VW drop spindle. The "axle" is moved up on the unit 2" from stock, which drops the car the same 2".

What springs were you running originally? The Gymkhana springs (550# springs available from VBP) should give you a nice drop and a decent (but not great) ride.

I lowered my 69 442 with a pair of Chevy S-10 drop spindles and by cutting one coil out of the front springs.

Rode and handled pretty good for what it was. Stopped better too because I used the disc brakes off the S-10.

In your case, the alignment shop should still be able to give you the proper alignment with 1/2 a coil cut. It does mean you will run out of adjustment sooner as parts wear. Drop spindles will give you the lowered stance without causing alignment problems. I've never heard of drop spindles messing up suspension geometry.

Personally, I would either get lowered springs or coilovers. I went with coilovers so I can lower or raise them easily should the need arise.

If there's a way to do something with or without the use of a torch, always pick the way with the torch.

Torching a coil spring is a no no. Use a hacksaw to chop.

You can also heat the spring to compress it, but you will mess it up.

Given the choice of a hacksaw or a torch, always take the torch.
