Scale guy out of state at race, no scales yet. RH spring is 14.5" overall length, 5.5" outside diameter, 4" ID. Lower control arm at level with cross member is 9.5"= 5" compression at ride height.
5.5"x9.5 springs are available in any spring weight. I will take the spring to the race shop and get it checked. More later.....

 

springs removed, safely with no spring compressor, cut to 11.5" and easily re-installed.
lower control arms are level with the weight on them. Scales arrived and will get the numbers on here tonight.
a/c compressor not mounted, rh seat not mounted, no water, no a/c unit and condenser/ fan in trunk, no exhaust and tailpipes only headers.

 

Okay, I will bite. How did you remove the springs without a spring compressor?

With me(220) in it: 1601 front, 1598 rear, bias was almost 50/50 and 50/50 side to side.
2764 without me and fuel weight .My Camaro is3150 with me and fuel load.

 

Car up on jack stands with tires removed; removed lower shock bolts(4), floor jack under a arm, remove spring plate bolts(6), lower floor jack and then remove upper shock bolt. Lowering the jack and removing the upper shock bolt is accomplished together.
The front corners were around 800# a 5 1/2 x 11 850# spring will be sourced and installed. When I cut the coils they got softer not firmer. Usually the other way around.

 

Called Eaton Spring and got a"BOOK" guy, nothing listed for Jaguar? Do you have 5.5"x12" 375# springs? The "BOOK" lists by make....
I have figured a way around my problem with minimal $ and work that will maintain my ride.
