inches, mm and spring rate if I knew it at thje time

v bn

hyper coil is 2.5 inch x 10 inch 175# linear
10.1mm or 0.397 inch

i also like the 8 inch one with a 2 inch 50# helper with the coleman hats. this keeps it in contact with the seats while the weltmeister stiff short lowering springs tend to unseat when you jack up the car.
2.5 threaded perch set up also unseats
coleman hats are deeper and have holes to tie the spring

oops: ground control is deeper. coleman has the holes
