the rear kit uses standard 2.5" ID 12" tall springs so you can buy them yourself if you can find a good deal...
True - and I checked, but the information is so scattered and confusing sometimes. Some people use the 8" springs that need to be 500# so they don't bottom. Others use different threaded sleeves that only work for specific struts. OFTEN no specific part numbers are given, just "for a Honda Civic"...
It was nice to get everything I needed in the ONE box that FITS.
I have 7" sleeves and 10" springs . I originally was going to use 12" springs but they hit the tire with the wider wheels.. I ended up with 375lb springs and the ride is stiff but not as stiff as I had figured..

I ended up using 350# on my '88 LS4 swap. The LS4 weighs about 100# more than the stock cast iron lump but I wanted more road feel and it matches up very well with the Held front coil overs.

What is the benefit in changing to coil overs? More tire clearance, better ride (softer/firmer), adjustable ride height, better handling? Never considered it as my 87 with poly bushings and swaybars seems fine so I'd like to know what the coil overs would improve.

I second on the great product.. I'm running their koni coilovers in the rear at 300# and I have the front suspension kit (upper and lower A-arms and adjustable coilovers)... I went 25# more than stock on those.. I also have their 1"drop spindles on the front.. On all poly.. Everything rides so nice and planted. I'm dropped about 1 1/2" or a little more... I've had this kit since they were called HT Motorsports and Lee was working there. I think he owned the place at the time?....
I also have their 13" rotor/ wilwood brake kit.. Everything worked great, as well... but I had to modify and weld new tabs for the parking brake caliper to have it slide on.... Originally, the caliper would slide off and jam in the rotor.. Bad news!.. NO more
