I'm making slow progress on raising the car's suspension, lack of ground clearance and lack of a coilover-collar spanner-wrench have been a bit challenging!

Good news is that I've got some Race Ramps in transit, and the
"previous-previous owner" confirmed that the JRZ's worked just fine at stock GP ride height. Here's some suspension candy:



JRZ also put me in touch with JRZ expert Andrew Brennan (Brennan Autosport) who's going to sort out these two problems:

 

Glad to hear you should be able to raise the car up a little with the current JRZ setup and still have good ride (suspension travel). Is that the rear shock bottom eyelet that is cracked? Looks like one shock had already been welded to fix a crack. Were the shocks scrapping on the ground?

 

Both rear shock bottom mounts are cracked and were TIG welded at some point. Then a nasty scrape took care of one of the welds...I'm not really sure of the history here , other than both shock bodies need to be replaced. What's odd is the bolts into the lower arms seem to be just fine, if a bit long. Maybe a speed bump?

Anyone have a photo of what the lower rear arm to shock looks like on a stock GP?
