Default dropped LCAs?

i remember seeing some lower control arms (i think they were lcas) that dropped the car 1.5 inches on stock suspension. ive searched for lcas on here but now im thinking they were another part.

sound familiar to anyone?

thanks!

I think you are talking about the front knuckles, not LCA's, that basically shortened the upright so the car sat lower without putting your axles at odd angles as would happen with traditional lowering methods. I forgot the name of them, maybe someone can chime in with that. They were powdercoated all sorts of different colors.

i think dropzone made them they made the shorter forks and a special rear lca that lower the car.

i dont think they make them anymore.

edit: suspension techniques made them.

Anything that lowers the car, will change the axle angle. The tire size remains constant and the axle attaches at the same height, but the chassis has been lowered in comparison. This will change the axle angle the same as a traditional lowering of the same amount.

However, with a drop knuckle, your suspension geometry will stay the same. As long as all dimensions except for the axle location remain the same, no changes to camber, caster, bumpsteer, etc...

Yeah I remember those from back in the day. I remember seeing a white 96-00 Civic 4-door with them in Super Street mag back in like 98 or 99. They were called DropForks and ProArms from Suspension Techniques (the car division of the BellTech truck suspension company).

Pretty trick items, although the LCA's had no swaybar attachment points.

I've seen those, but haven't seen any reviews or anyone who has actually used them.

Looks like a pretty good idea, all suspension components would retain the same angles as it did at stock height with stock components. Then if you wanted to you could use just a mild lowering spring to get a more extreme drop, but with minimal effects on suspension components.

Lowering a 92-95 or 94-01 Integra the "traditional" way, we seem to run out of suspension travel before the tire drags against the fender. With a drop spindle like this, when during the suspension travel will the tire contact? Is anyone here a suspension engineer? Can anyone say that roll center, instant center, camber curve, etc..., are better with the control arms in their stock position or better for handling in a lowered position? Lowering a car without changing suspension angles sounds like a good idea at first, but there can always be unforseen consequences.

Example:

Where is the attachment point for the toe link? And is it just me, or does the RTA bushing seem like it wouldn't allow the same range of motion that the stock unit does? Similar to how polyurethane RTA bushings will bind.

You are tripping. The only thing these do is move the hub upwards. Well besides reducing weight. Compared to traditional lowering methods, there are almost no side effects (except ground clearance of course). Just stick to your lowering springs and aftermarket rear LCAs.

Those spindles make the ball joint pretty damned close to the tire. Plus they cost as much (almost) as a new suspension does. $500+. Lowering is one thing, body roll and performance is another.
