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?

There's some conflicting ideas that seem to be going back and forth here. You can either set the corner heights perfectly to your liking, or you can have a shop put your car on scales and balance the weight at each corner to optimize handling.
The compromise you have is that that the stock rear perches - unless you use shims to raise or lower the perch - cannot be finely tuned. Therefore, the shop will use the height adjusters in the front to balance the weight as best possible between the 4 wheels. You will end up having slightly different ride heights at each wheel. You can tell if you have 911 a arms if by the torsion bar spline count - I don't recall the number difference, but you can't interchange them. Sounds like this is a new setup, and you haven't really tried any of it out. If I were you, I would set right height, get an alignment only (or do your own), and drive the car to see how it handles. If you autocross or drive hard, take notes on what you like or don't like about it. I would suspect with a sway (stock or aftermarket?) and the 911 front end (depending on size of tbars), you might get some unwanted understeer. You can play with the sway bar and see if you can tune it out, but you might need stiffer springs (like 165 progressives (IMG:style_emoticons/default/happy11.gif) ) for the rear. Regardless, I wouldn't spend the time/money on a corner balance until you know you dont have to make any big adjustments to springs/tbars. |
