Lowering (I know)
I've looked through old threads for 2 hours.
Does anyone know how much one turn on the lowering bolts raises or lowers the car front and rear?
I really don't want to be all the down in the front because I'm scraping everywhere, but I raised it (w/o measuring first, of course) and now I'm too high. This is after lowering the car a couple weeks ago.
Thanks, Cannon

Is there some kind of lever effect working here? I only raised the front 3 turns and I was way higher (by at least an 1/2") in the front than I wanted to be. I was shooting for 4 1/2 or a bit higher in the front. I don't have my measurements at work with me but it was a bit over 5" at the front jacking points. I think I did about 3 turns in the back and now it's over 5" (again, I have the exact measurements at home) at the back. I'm trying for just a touch under 5" at the back jacking points. I'm on stock size F1's with about half wear to the wear bars on the tires.

I think you`re just going to turn them a few turns at a time then check it after settling til you get it where you want it. These cars height will vary a bit all the time. maybe a quarter inch. from one park to another.

Yes, there is. Turning the bolt enough to move the bolt 2 or 3 mm will lower/raise that corner MORE than just 2 or 3 mm. Just how much... well, I couldn't really tell you. It seems like most of us have to just keep adjusting it until we get it where we want. I'm actually about to lower the front of mine a tad bit more, because I feel there's not quite enough rake.
Also keep in mind that the car will require a little bit of driving for the springs to settle back down. After every time I've jacked the car up in the air, it seems like the car is sitting about 0.5 to 1 inch higher than normal, and usually lasts for about 5-10 miles or so.

once you change the height you need to drive it hard for a few miles to let it settle and then measure. You ever notice how much clearance you have between say your jack at it's lowest position when you first start, and then when you drop the car back on the ground and pull the jack out the gap is a bit bigger?? Everything needs to settle before you can get accurate measurements.

Take it to an alignment shop that can do these cars lowered .. I had mine done at a place locally that we use for car's our rack can't handle and they had no problem doing mine. It's lowered to the max and alignment is perfect.

Another point to remember. You can't just raise the front without also raising the rear. You must have a slight rake with the front about 3/8" lower than the rear for proper handling and high speed aero effect.

I measured mine at the top of the fender on all 4 corners..It takes a while for the car to settle after jacking it up.

The proper place to measure ride height is the jacking points. The fenders vary all over the place, they are just plastic and hung on so that the look right. The frame relative to the ground is what you want to measure.

Now even as a newbie. I may just be inclined to agree with SoloI have also come from the aviation world where X number of turns BETTER leave X number of threads showing. Integrity factor.

Yes I am the green horn here, the newbie.
With regards to my comment on the threads count it was in the intrest of safety.
I am most certain that there is a 'call out' somewhere on how far a nut may be backed out and be safe. (just don't want the nut running off on the guy)
In truth I have never been under the car, or even know which way he's turning the bolt...
Just wanted to make sure he left alittle something for it all to hold onto.
