This is an old thread, but it is my old thread so I figure I can bring it back to life if only to close it out.
This is the $1,500 TR4a IRS that sat for 25 years in a car port, suspension was all goofed up with mismatched parts. When I sorted that all hot she was sitting too high, which I was bemoaning above. I swapped out the rear springs which took care of that end of the car but then she was in a tail-low stance. Not good.
The new Richard Good springs finally went in today, and as with all his stuff they were perfect. I hereby pronounce her level, lowered, and ugly, but ready for fast road use.
Thanks for all of the help and coaching along the way!
