Thanks for everyone's ideas and info. I have a plan. I'm a little gun-shy to just order new springs, since I got burned by the Detroit Speed springs that weren't as advertised.

Plan A) install 1" lowering blocks and do the Herb Adams modification to the front spring mount which should drop the car by about another 3/8". (I didn't do this the first time around because I thought it would be too much with the advertised 2" drop). Going to raise the front by 1/2" and then see how things look and check ground clearances. If that's not enough, then...

Plan B) take out the lowering blocks, buy the Hotchkis springs that 76TA462 described in post #5 and see how that works out.


Thanks again,
Eric

Update: I did the Herb Adams mod to the front mount and put in the lowering blocks. It's still not low enough and I don't like how far the springs are out of the axle brackets. Road courses will put lots of side load on those.

So it's time for Plan B...Hotchkis springs. I had a good talk with John Hotchkis yesterday and he was pretty interested in my project. He's going to sell me the springs only; since I have all the other parts from the 2409c kit.

After doing a lot of research, I see the problem. The Detroit Speed springs have an extra leaf and are just too stiff. The Hotchkis springs are progressive.... they compress a bit before all leaves are engaged. Also, Hotchkis has different springs for 70-73 vs 74-81. Detroit Speed has a one size fits all. I have no clue what's the difference.

30 day wait for the new springs so it's on to other tasks.
