Please your advice people!!

After buying the car 2 months ago I noticed after a while that it had an uneven stance; the right rear fender gap was 20mm( 0.8inch)smaller than the opposite side.The left front fender gap is 10mm(0.4 inch) smaller than its counterpart.

So it is as if the car's weight rests more on the right rear/left front wheels.

We attributed the fact to spring sagging.

I believe the previous owner drove for two years with a defective right rear shock (I thought that was the reason for the excessive drop on that corner).

However, after installment of 4 new tokico shocks and SE lowering springs ,all fender gaps are reduced by the amount advertised by SE,but the stance remains crooked.

 

What could have caused this phenomenon in the first place?( My tech guy is fairly confident the car had never an accident.)

 

 

Should I have the car measured up in a chassis rig to check any torsion?

 

Should I raise the right rear corner with a spacer above the springs or should I clamp the opposite side?

Hallo Hendrik,

 

I just went through this as a step to cure camber issues. You need to find some bodyshop with a proper compoterised digital measuring jig. Something like this

http://www.blackhawk.co.uk/uk/shark/sharkfirstpage.html

 

This will check your chassis / body to within 1mm in 3d on set datum points.

 

Once you know how the car is out, then you can think about how to cure.

 

The old tech of removing the suspension to mount physical jigs is timeconsuming and expensive - I was quoted about £400 or £500.

 

The computerised method cost me £80 and the body shop said the car was within the tolerance they would expect (they try to get within 2mm but settle for 5mm)

 

Most body shops had no idea, I had to find one through the trade association.

Is the car fitted with stock rear arches?

yes, the arches are stock.

Could the uneven stance have something to do with worn subframe bushings or worn bumpstops?

HHhhhhhhmmmmmm

I've ordered new Blitz springs and Koni shocks as my Z is about an inch lower on the rear passenger side than on the drivers side.

I hope the springs sort it after reading this!

The shocks are shagged anyway but it's the only reason for the new springs...

 

sorry guys, should have double-checked the measuring.

I took the car on a nice flat parking lot today and there the measurements were 100% symmetrical.

It seems that if your driveway is not level or flat as a snooker table you will get rather large differences in fender well gaps.

Should have done my homework first!

cheers
