When it comes to front swaybars. Do you need to adjust them? I bought Heim joints, installed them. Now is the height of the sway bar important to anything? I've never heard of it, but I feel the need to ask.





Just checking if i want to put on the Verde flares or not


RSRacing Suspension lifted as high as it will go on the rear perches. Car can come down 2" in rear still.


Exhaust is so close to ground. like 2.5 inches. Thinkin' of side exhaust.


OMG... You can see my licnese plate number. OMG... Noooooooooooo... Please dont find me. Oh wait what am i thinking. Thats for the weak minded idiots that think you need to cover them up.


I think i need drop spindles, based on lower A arm angle




This is what my exhaust will look like when i am done. Or i might have to go with side exhaust because the car sits very low and scrapes. I made the aluminum plate already but have no photos of it.






Here in MN Spring is around the corner. I cant wait to start working on my car again.
Its in Storage just sitting under a car cover waiting to be driven.

What you are supposed to do with the swaybar is cornerweight the car (can be use with your adjustable rear spring perches) then adjust the end links so they are just the right length to fit when the car is level, not pulling up or down at all. Its probably more complicated than that, but thats basically why they are adjustable.

I remember when my front end looked like that. I had the RSR coils working with dropped spindles too! You have to make a new bracket to attach it though =)

When the car is slammed, usually the sway bar will tilt upwards which should make it stiffer and bind just a bit. It also puts more stress on the sway bar mount. I would adjust it so it sits as level has possible with the ground, then adjust the preload until there is none. Car looks sharp!

So when the car is sitting naturally, Wherever I decide to set the suspension. I need to make my sway bar perfectly horizontal. Is that parallel with the earth or parallel with the body of the car? Lets say for argument that the car is 3 degrees lower in the rear. Would I follow this 3 degree angle with my sway bar? So thats the reason the end links are adjustable?

I have to make a new bracket to attach what? Everything is attached all ready.

It's NOT critical, but ideally the front sway would be level with the chassis rails.

Either way you probably won't notice much if the sway is pointed up slightly, and the links have a bit of preload on them ;)

I think it would be more noticeable if you get the car corner balanced, with you sitting in the driver's seat. Then get the car aligned one last time.

The brackets I was referring to are only for dropped spindles. The RSR coils are too short to use stock with dropped spindles.

I dont' see reinforcement plates in there for the front sway bar mounts...how big is the actual bar? 30mm or so?
The plates aren't on yet. Thats where i finished off last fall. now its almost spring for us here in MN. Then i can continue where i left off. Yes its the 30mm RSR bar. I ordered my own rod ends for I didn't see the need to spend over !00 dollars where I could order my own parts for half the price.

Grant are you saying that I can't use Richards drop spindles with the RSR coils? I don't see what one has to do with the other. But you had this before and I didn't. Are you saying I need to make a perch to sit on my lower A arm to raise the RSR Coil setup an inch if i drop the car an inch via drop spindle?

Yeah, the RSR coilovers don't have enough droop to work with aftermarket spindle lengths. A buddy machined out an aluminum spacer for below, and I used a stiff polyurethane shock bushing on top to space the shock down.

So, to clarify, the swaybar will move up and down as the front suspension moves up and down, (presuming both sides are moving up and down together - imagine driving straight over a speed bump with both tyres) so, to that effect, the angle of the bar at rest is pretty irrelevant; it is meant to vary with a-arm motion. What is relevent, however, is the relative lengths of the right and left heim drop links, making them different lengths causes the sway bar to twist and creates preload, this is how the cornerweights are tailored.

shortening one side causes the sway bar to 'lift' the a-arm by a small amount in comparison to the opposite side of the car, which essentially takes a little weigh off of that wheel and vice-versa. (working with the car on perfectly level ground)

I hope that makes sense, it's a pretty simple explanation and I sure as heck don't know how to set up a car as well as some of these guys^^^^^^^

^ That's not true, if you start at lower ride-height (so the sway bar is angled upwards) when you enter a turn and put the twisting force on the sway bar, it will have less leverage and effectively make the bar stiffer, while binding slightly and putting more force on the already compromised sway bar mounts.

That 30mm bar is ginormous and very heavy. I had one but I sent it back. I requested a 28mm bar instead. Other cars utilize hollow bars when they get large...

Absolutely agreed, but with the lever lengths of the whole system, pivot points and travel of the system in mind, the tolerances are more like inches than hundredths before you start getting any noticable effect, due to the sway bar radius of motion being the longest lever in the sytem by far. My only concern would be to prevent the sway bar from topping out on anything underneath at the top of the suspension travel.
I'm not clear on what the sway bar would be binding with either. It should be free to move right through and beyond its useful travel, as should the heim joints, if they dont, they need some tapered spacers
