nice write up FireSilverLullaby.

I'm assumming driver side is a tad higher because the majority of time driven there's only a drivers weight on the high side evening level.also most cars have differnt weight on all four wheels.

I have changed every bushing on this car ( at low speeds it has a sqeak) except these, on my 300zx these booties wore though the spring created a sqeak.These thing look kindoff thick for a spring to wear though?

I'm assumming the ride quaility has harshened some?

When I replaced all my rubber bushings w/ polythuothane ride majorily harshed?

anyone concerned w/ u=joint angle change?

Thanks

i wouldn't be surprised if the ride height is different due to the spare tire. what size hose is recommended for the best?

Well, that can't be the case since I have removed my spare tire, and put a sub box on the driver's side and still have a 1/2" higher stance on the driver's side.

Thought the extra spring rate is probally there to compenaste for the torque applied to the rear wheelks under acceleration.

as noted in the first post - rotate your rear springs to correct height differences.

I am about to replace my stocker shocks and I am torn between the bilstiens and the koni's. I want to but cant lower my car much due to 3" dual exhaust all the way back.. I have like maybe a pop can worth of room to the ground from the pipes. the rear on mine was over 28" from ground to fender in the back and about the same as what ive seen in this post in the front. The gap drives me crazy.. I wanted konis for the front lower perch to lower the front along with the back HH mod on stock springs, either that or Bilstiens and just do the HH mod on the rear.. what do you guys think?

Yes. The hose takes it's place.

Correction.... from the ground to the fender at the middle of the wheel i have 27 1/4" LF 27" RF and 28 7/8 on both rears.. Do you guys think i should just go with the HH mod and use bilstiens with the stock springs or go koni and lower the front and do the HH mod?? a little off topic but im sure a few are wondering the same thing. I was wondering about the HH mod on just the back making it look like the back is squating like others have mentioned.

I would go with the Koni's. That's what I am doing.

There is really no easy hose mod type fix for the front but your options are koni shocks have a lower perch that you can mount the spring on & it will lower the front (but they are not cheap) or buy lowering springs(gonna still need better shocks) or cut your stock spring(not recomended but with a good shock is not too bad) Good luck w/your choice!

I actually got Konis recently so I could have used the lower perch on the fronts and done the hose mod, but I decided I want ground clearance more, don't feel like scraping everywhere, plus I can just barely get on my ramps as it is.
