What Spring rate?, My 100# springs are on backorder... Options

[bmtrnavsky]

I ordered some 100# rear springs for my 73 2.0 and just found out they were on back order. My stock springs are toast... Everyone always says WOW! you set that up really squatty in the rear, and I'm like ya the springs are toast... so I was planning on putting in some 100# springs with Boge shocks. The fronts are done now and it is a BIG improvement already, but I have been waiting on my rear springs to do my rear shocks all at once. I don't really want to wait until October to finish this job, so my choices seem to be a stock spring... I don't really want this, a 90# at factory ride height, 140# lowered 1.5 inches, or the stock 65# spring. At this point I realize ANYTHING is better than what I have... but I am leaning towards the 140# springs.

I commute in the car on nice days but the car is mostly driven for fun, and I REALLY want to start taking it to the track for AX. I thought the 100# was a nice balance in performance and ride... is the 140 pound going to ride too harsh on the road?

I guess it's subjective, but I don't want to ruin it's manners on the road where it spends 90% of it's time. But I also want the car to handle really well and I get that I will have to make some compromise.

Thoughts?
