So, if you were swapping in a big block, but wanting to keep excellent ride quality as more important than ultimate cornering, but still wanted to not have to slow below the speed posted on the yellow warning signs, on 245/50R16 tires, what springs would you choose?
Moog's 5610s are listed as 11.00" load height, 0.69" wire diameter, 420 lb/in rate, 15.16" free height, and 2444# total front weight. The 5664s are 10.75", 0.76", 767, 13.18", and 2618.
And how about KYB GR2 struts? I'm thinking of buying and installing a pair of these at the same time, to replace my old mystery struts.

 

It seems the 5610s should ride best, but not if they let it keep bouncing off the bumpstops. The 5664s being a factory item, should be tolerable? Anyone?

 

Nevermind, I missed out on that Rat, someone bid $1 more than me, in the final minute. Dammit!
