So after getting the trailing arm rebushed on the drivers side I wanted to check the rake. The rake looks good. I checked for level port to starboard and I got a lean. Almost like the s10 lean when the big dudes drive around on them all the time and the springs get sad. Front is leaning too. So my question is - Will the rear suspension affect the front suspension in regards to balance? I realize if the driver rear is super low it will have some affect on the driver front, but its almost like a 1:1 ration where as I thought the front would not suffer as much.
Oil tank is on the driver side accounting for some of the additional weight. I was not in the car when checking the side to side level. Rear springs are 100lb 914-6 ones two perches up on both. Front is an SC setup with a front sway bar. Will new rear springs solve all my problems or do I need to investigate something else like adjust the front driver adjuster also? At the donuts Drv F - 4 & 7/8 Drv R - 5 & 7/8 Pass F - 5 & 7/8 Pass R - ~6 - hard to determine as there was console work done on that side and the donut was remounted at an angle (IMG:style_emoticons/default/headbang.gif) From those numbers it doesn't seem like the rear should have as much variation, but it does. The fender on the Pass R is about 2 in higher than the Drv R. Maybe the guy that put on the flares was careless (IMG:style_emoticons/default/confused24.gif) The lowest point seems to be the Drv F with 1 inch lower than the pass F and Drv R. So maybe if I adjust the drv F and get that donut in line with the pass F then I can start to adjust the pass R down one notch to bring it even with the drv R. Is this logic sound? Where you at Phil?

I don't know if I can explain this very well in words but let me try.
I think of weight (and ride height) distributions as a 3 legged stool. It takes 3 points to establish a plane (i.e. the level ground the car is sitting on). When balancing race cars you'll forever fight the 3 legged stool trying to get all 4 corners to balance perfectly. Using the 3 legged stool analogy, you'll tend to find that two legs are carrying the majority of the load . . . the other two are more lightly loaded and the car is sort of "teetering" back and forth across the diagonal. One of the two that are more lightly loaded, one will be heavier than the other. Picture: H=Heavy L=Light empty circle = lightest corner So in top picture we would want to add weight to #3. #1, #2, and #4 are the 3 legged stool But when we do that (bottom picture) you'll find that the diagonal bearing the weight can shift and all of sudden #3 becomes heavier than you anticipated and #4 is now too light and/or becomes the lightest corner. The weight sort of "toggled" or falls over to the other side of the two legs that were "tallest" . #1, #2, #3 are now the 3 legged stool I'm not really doing this justice in words. I've just learned this 3 leg analogy from corner balancing a lot of cars and watching how the weights and ride heights shift in relation to changes corner to corner. So in your case, with the driver side listing, with the car being lower in the front, I'd focus on bringing the driver front corner UP. That will move some weight to the passenger side and also will move some weight to passenger rear. However, you will get more weight transferred to the passenger side front (and lower ride height on pass side) with less of it going rearward to passenger rear. If that doesn't do it alone, you might need to drop the passenger rear shock one detent. At that point, I wouldn't be surprised if you find the driver front too high, and then need to lower the driver front. |
