Here's one for the Sherlok Holmes of Miata world.
Apologies for the long post but I need help. My 93 LE with original bilstein shocks is a different height on each corner.
I don't know if the car's unibody is crooked due to a collision or the springs need to be changed. I've tried several fixes and I'm close to fed up with the issue. The car, from center of wheel to fender, is FL/12, FR/12.25, RL/13, and RR/12.5 and this makes me sick.
Old Bilstein shocks are still in really good condition (checked by several mechanics) and the car does drive like no other miata. The springs are the right color for the year (f/red & r/yellow), and each pair is the right measure.
Last mechanic I talked to suggested that the factory springs, although measuring the same, may be too old and so their rates are now all different and i need new springs. But I'm so frustrated that if i buy new springs and don't work, I'll shoot the booger.
I thought of cheap coilovers like Godspeed or Megan and adjusting the ride height as i please, but I just don't want to give up on the quality of the Billies--they are really amazing. So now I am more inclined towards your Ground Control/Eibach kit. But I wonder if ride would be unbearable (I live in pothole heaven Puerto Rico) and whether GC's are compatible with Bilsteins at all as they state "no sport suspension" on GW's site.
Car is used 3-4 times a week, including the spirited Sunday drive. I really don't want to spend over $600. (Actually, my wife would kill me if I spend that much.) The car has brand new polyurethane bushings all around.
So, what do you guys think? Springs? Cheap coilovers (with the added benefit of fancy adjustable damping)? old billies with Ground Control? Shooting the beast?
Any commentary would be greatly and respectfully appreciated.
