suspension Question on CRX alignment!!
ok my CRX was aligned perfectly a couple months ago before i lowered it with Lowering Coil overs (Ground Control)........ and when i lowered it i didnt measure perfectly from the rear passanger side and rear drivers side coilovers, and ever since my alignment was off, so today i figured if i measured all 4 coilovers to be dropped even that the cars alignment would be fine!!, but its not!! it still pulls to the right, What is my problem????????? this is very aggrevating!! Thanks
I BELIEVE that the toe is the thing that is causing your car to pull like that BECAUSE the crown of the road (tilt to drain water, ect...)
or am I off.......does it pull even on flat ground?

all cars pull naturally to the right---also keep in mind you have a car w/out an intermediate shaft causing 'torque steer' even though there is no torque.lol
Modifying the caster (in general on all cars) is what is done to compensate for road crown. Changing caster can induce a pull to one side without affecting tire wear.
All cars can pull to either side IF the Toe-In is not set correctly. This is caused by the "crown" in the road. Anyway. Take a machinist adjustable 6" square or a really good tape measure and set the perches so that they are the same on the rear from side to side and do likewise for the front. What I do for a baseline is measure the distance from the ground to the jacking points and get all 4 corners as close to the same as possible. For Improved Touring we are allowed 5" of ground clearance so that is what I shoot for. This is also a home-brewed corner weighting technique.
Having done that it is time to return to the alignment rack. You will find with the 5" ride height that the rear should be very close to -1 degree (still in spec, btw). The front will be around -2.2 degrees and thus very far out of spec. In fact, the driver's side negative Camber will be very obvious and nearly 1/2" in on the top. Solution for this is Specialty Products kits that sell for $150 for both sides or your choice of another brand. The kits I am using are replacements for the anchor bolts (another rule) and they have a range of 1.75 - 3.25 degrees. The 1.75 will get you to around -.45. This is about where the car started life. Setting the Toe-In for your roads after all of this will make driving a lot more comfortable and predictable.
As was stated before-cars do pull due to torque loads and road "crown." There is little other than a good alignment that will help compensate for this. An alignment is strongly recommended any time you take the suspension apart or change ride height.
Good luck.

Toe is the one part of a CRX that is adjustable. The front is adjusted via the tie rod ends and the rear is adjusted throught the swing arms.
A good thing to check before you alignment is that all your tires have the same, correct, air pressure.

You beat me to it slowpokesi.
Just like he said. Everytime you mess with your suspension, you have to get it re-aligned. Raising or lowering the coilovers will cause the toe to go out. I'd suggest you adjust your coilovers to exactly where you want them, and then go get it aligned. Just remember, if you drop it too low, then you will need a camber kit.
A alignment is needed after a camber kit install.

Just to second on all the big things mentioned for installing parts, make sure things that need to be preloaded are installed at ride height, make sure tire pressure is correct, and align when finished. If you don't have access to a rack, get it done somewhere familier with correctly aligning modified suspensions on Hondas.
